Similar to both weekend mornings, a large area of stratus clouds sits mainly over inland locations with a few patchy clouds elsewhere to start the day. A southwesterly air flow developing over the region is pushing this stratus layer to the northeast but as the morning goes on it will erode away and dissipate, and today’s diurnal cloud development will be less than the previous 2 days when we had a northeast breeze Saturday and southeast breeze Sunday. Today’s southwest wind will transport warmer to hotter air into the region and it will feel a little bit more like the middle of summer. But now you’re noticing, that sun angle – not quite as high as it once was. And it’s not setting after 8 p.m. not even after 7:30 pm. anymore but earlier and earlier in the 7:00 p.m. hour. But most areas will see it set today as we’ll have far fewer clouds about during this evening. The high pressure heat pump will be at it again Tuesday which will be a pretty warm to hot and somewhat humid day by late August standards. A cold front approaching the region will not do so quickly enough to send any showers or thunderstorms into the WHW forecast area before the day is over. We’ll see some clouds in the western sky later in the day from this activity to our west, but the remains of it will be all that make it through here overnight. The cold front responsible for it will still be moving through the region Wednesday morning, so the chance of showers or even a brief thunderstorm will still be there mainly for southeastern NH, eastern MA, and RI through about midday. In addition, during the morning a little wave of low pressure moving by Cape Cod may toss a swath of showers up across that region. But Wednesday afternoon, drier air arrives, and while it will be quite a warm day, you’ll notice the dew point going down as the day goes on, once that front goes by. Any additional afternoon showers on Wednesday look like they will be confined to the mountains to our north. So ends August, and September will begin on a dry and slightly cooler note Thursday and Friday as high pressure builds into the region from Canada.

TODAY: Early morning clouds abundant in parts of eastern MA much of central MA, RI, and eastern CT, with more sunshine elsewhere, then sunshine dominant thereafter with just some passing fair weather clouds. Highs 84-91, cooler South Coast. Dew point 60+. Wind SW 5-15 MPH.

TONIGHT: Mostly clear except a few patches of low clouds and ground fog. Lows 64-71, warmest urban areas. Dew point 60s. Wind SW up to 10 MPH.

TUESDAY: Partly cloudy. Highs 86-93. Dew point 65+. Wind SW 5-15 MPH.

TUESDAY NIGHT: Variably cloudy. A shower or thunderstorm possible mainly I-95 westward. Patchy fog. Lows 65-72. Dew point 65+. Wind SW 5-15 MPH.

WEDNESDAY: Variably cloudy until midday with a shower or thunderstorm possible I-95 eastward, then sun and passing clouds. Highs 81-88. Dew point falling to 50s. Wind SW shifting to W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 57-64. Dew point falling toward 50. Wind W 5-15 MPH.

THURSDAY: Sun and passing clouds. Highs 76-83. Dew point 50s. Wind NW 5-15 MPH.

THURSDAY NIGHT: Clear. Lows 53-60. Dew point near 50. Wind N up to 10 MPH.

FRIDAY: Sunny. Highs 73-80. Dew point 50s. Wind variable up to 10 MPH.

DAYS 6-10 (SEPTEMBER 3-7)

High pressure will be the dominant force for Labor Day Weekend September 3-5 with warming Saturday and Sunday as high pressure overhead sinks to the south, and then a frontal boundary will come through likely dry and Canadian high pressure will bring slightly cooler air for Monday. Fair weather should continue into late period with another warm-up.

DAYS 11-15 (SEPTEMBER 8-12)

We’ll watch for a frontal boundary crossing with a possible shower around September 9 and possibly some offshore tropical activity later in the period, otherwise high pressure should dominate with mostly dry weather and near to above normal temperatures.

C-19 Chat Post – 8-29-2022

DAYS 1-5 (AUGUST 28 – SEPTEMBER 1)

Early this morning a stratus blanket sits over much of the region but this has already been eroding from east to west so that many eastern MA and RI areas as well as the NH Seacoast are seeing sunshine, and this is progressing inland with time and this general trend will continue. Although a few clouds may be stubborn in some areas and others can redevelop in the form of cumulus clouds as the sun’s heating increases, similar to yesterday. All in all, we end up with a sun/cloud mix but a rather nice day, thanks to high pressure centered to our east. This high will slip southward into the “Bermuda High” position to start off the week, so our heat and humidity levels will increase Monday into Tuesday, but not close to the levels of previous hot spells this summer. Also, it will be rather short-lived as a cold front approaches and passes through the region between late Tuesday and midday Wednesday, based on current expected timing. This timing is limiting for showers and thunderstorms, with most activity during the day Tuesday to our west and north, diminishing before it arrives in this area, and most of Wednesday’s activity firing up to our east if the front is quick enough, and possibly over southeastern NH, eastern MA, and RI if the front is just a little slower, with activity favoring the morning and midday. Today’s forecast update will take into account either possibility and then of course it will be fine-tuned as we get closer with the help of short-range guidance early in the week. Thursday is the first day of September and on cue a Canadian high pressure area will deliver us a fresh air mass from our neighbors to the north, for the first day of meteorological autumn.

TODAY: Clouds dominate inland areas and parts of the South Coast early, otherwise a sun/cloud mix. Highs 77-84, coolest coast. Dew point 60+. Wind SE up to 10 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind S up to 10 MPH.

MONDAY: Mostly sunny. Highs 84-91 except cooler South Coast. Dew point 60+. Wind S 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60+. Wind S up to 10 MPH.

TUESDAY: Partly cloudy. A late-day thunderstorm chance north and west. Highs 85-92, cooler South Coast. Dew point 60s. Wind SW 10-20 MPH.

TUESDAY NIGHT: Variably cloudy. Isolated to scattered showers and thunderstorms possible. Areas of fog. Lows 67-73. Dew point 60s. Wind SW to variable 5-15 MPH.

WEDNESDAY: Partly cloudy. Showers possible favoring southern and eastern areas early in the day. An additional shower or thunderstorm possible through midday southeastern NH, eastern MA, and RI. Highs 83-90. Dew point 60s but lowering slowly. Wind W 5-15 MPH.

WEDNESDAY NIGHT: Mostly clear. Lows 57-64. Dew point falling toward 50. Wind W 5-15 MPH.

THURSDAY: Sun and passing clouds. Highs 76-83. Dew point 50s. Wind NW 5-15 MPH.

DAYS 6-10 (SEPTEMBER 2-6)

High pressure is expected to dominate with fair weather and a slow warming trend from September 2-5 which includes all of Labor Day Weekend. A frontal boundary may get closer with higher humidity and a shower threat by the end of the period.

DAYS 11-15 (SEPTEMBER 7-11)

A frontal boundary may be close by early in the period with a shower threat, then high pressure takes over with another stretch of fair weather, starting cooler than warming up. We may have to watch the waters to our south and/or southeast for a tropical system out there by later in the period as there are signs of a little more activity in the tropics in the days to come and somewhat more reliable medium range guidance has been putting systems out there around that time. At this time of year it’s always necessary to pay attention to this regardless of how quiet or active the season has been thus far.

C-19 Chat Post – 8-28-2022

DAYS 1-5 (AUGUST 27-31)

On this final weekend of August we enter the final 5-day stretch of meteorological summer. But don’t worry too much, if you are not ready to say goodbye to summer you can wait until the end of tourist summer, which is September 5 (Labor Day), or stretch your summer out even longer by waiting until the actual end of summer on September 22 (the autumnal equinox). If you wanted to say goodbye to “solar summer” (the 3-month period with the most sunlight), you’re too late. That ended on August 7. Maybe next year! But anyway, what do the last 5 days of meteorological summer look like, weather-wise? The weekend weather will be dominated by high pressure that is centered to our north today with a light northeasterly air flow, then with its center shifting to the east of the region Sunday, the air flow will shift more to southeasterly. This provides fair and seasonable weather, coolest maximum temperatures along the coast and warmest over the interior, and not bone-dry but tolerable humidity levels. Early in the week, high pressure sinks southward, into a position to deliver us more heat and higher humidity. We won’t be returning to the high heat levels previously seen in the summer, but nevertheless some areas make a run at 90 Monday and possibly crack it Tuesday. We’ll be watching the approach of a cold front later Tuesday that should be passing through the region during Wednesday. The details to be worked out regarding this include a more precise frontal timing and any rounds of showers and thunderstorms that occur. Right now leaning toward most of the unsettled weather being in northern and western portions of the WHW forecast area late Tuesday and pushing east and south through early Wednesday, with an additional shower or thunderstorm possible during the day Wednesday. Obviously, more fine-tuning is going to be needed for this part of the forecast.

TODAY: Sun/cloud mix. Highs 76-83, coolest coast. Dew point 60+. Wind N to NE 5-15 MPH.

TONIGHT: Variably cloudy. Areas of fog. Lows 60-67. Dew point 60+. Wind E under 10 MPH to calm.

SUNDAY: Partly sunny. Highs 77-84, coolest coast. Dew point 60+. Wind SE up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind S up to 10 MPH.

MONDAY: Mostly sunny. Highs 84-91 except cooler South Coast. Dew point 60+. Wind S 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60+. Wind S up to 10 MPH.

TUESDAY: Partly cloudy. A late-day thunderstorm chance north and west. Highs 85-92, cooler South Coast. Dew point 60s. Wind SW 10-20 MPH.

TUESDAY NIGHT: Variably cloudy. Isolated to scattered showers and thunderstorms possible. Areas of fog. Lows 67-73. Dew point 60s. Wind SW to variable 5-15 MPH.

WEDNESDAY: Partly cloudy. Showers possible favoring south and easterly areas early in the day. An additional shower or thunderstorm possible midday or afternoon. Highs 83-90. Dew point 60s but lowering slowly. Wind W 5-15 MPH.

DAYS 6-10 (SEPTEMBER 1-5)

High pressure builds in and may dominate this entire period with dry weather, a cool-down at first and maybe at the end of the period again, with a warmer spike between them.

DAYS 11-15 (SEPTEMBER 6-10)

There remain some uncertainties about the pattern here, but the latest trends are for high pressure to be dominant with dry weather much of if not all of the time and near to above normal temperatures. This isn’t a high confidence forecast though. At this time of year, interactions of even distant tropical cyclones on the larger scale pattern and even our own closer-by tropics, which have been quiet, can become a factor in a short period of time.

C-19 Chat Post – 8-27-2022

DAYS 1-5 (AUGUST 26-30)

Our focus today will be on the thunderstorm chance for the region. Even as I write this update in the 7:00 a.m. hour the short range guidance differs on timing and even coverage of showers and thunderstorms in the area today. Based on this, and knowing the fickle nature of convection anyway, my idea is to forecast isolated showers/storms for the first part of the afternoon anywhere north and west of Boston, and then one or two line-segments or clusters of storms any time from late afternoon through early evening, with the heaviest favoring being in central to northeastern MA and southern NH. We’ll have to watch how far any initial batch can perpetuate itself into areas further south and east as it may have to rely on an outflow boundary and no other focus other than the pre-frontal trough that helps initiate it. Some of the short range guidance develops additional showers and storms in the early to mid evening hours especially along to south of I-90, and some of this could survive toward the South Coast later in the evening. We’ll just have to watch how things evolve and kick into now-cast mode when needed. As a side note, I’ll be in southwestern MA much of today and will try to monitor from there as best I can – though I may have limited access. Thunderstorms have the capability to be severe today, so if you do have outdoor plans or will be traveling, please keep this in mind. Main threat is damaging wind, with hail being a lesser threat. Any storm can produce torrential rain which can drop visibility very low and cause quick flooding, and lightning as well which are always dangers whether a storm is deemed severe or not. Activity settles down by later tonight and the frontal boundary glides through the region under cover of darkness, exiting via the South Coast early Saturday. While the frontal boundary won’t sit all that far to our south this upcoming weekend, it looks like it won’t really have the ability to generate any further activity that would impact our region, so it looks like a fair weather weekend, governed by high pressure that will first be bridged across the St. Lawrence Valley Saturday, with a north to east wind in our region, and then slide its way to our east bringing a southeasterly air flow to us on Sunday. This will turn more southerly Monday as the high drifts to the south and we warm up most efficiently at that time. One more bout of heat may be ours for Tuesday as the high drifts down into the favored location off the Atlantic Coast to deliver that to us. Wildcard for Tuesday: How fast does the next front approach. If it’s quick, we have the thunderstorm chance later in the day, if not, it’s just a fair but very warm to hot day. I’ll look more at that in the coming few days.

TODAY: Sun/cloud mix. Isolated showers/thunderstorms early afternoon mainly southwestern NH and central MA, then showers/thunderstorms more likely in one or two waves favoring central to northeastern MA and southern NH mid afternoon to early evening with a few storms probably into northeastern CT and northern RI to interior southeastern MA by then. Any storms can be severe with damaging wind gusts. Highs 83-90, cooler in some South Coast locations. Dew point middle to upper 60s. Wind SW 5-15 MPH but can be variable, strong, and gusty near any thunderstorms.

TONIGHT: Variably cloudy. Scattered showers and thunderstorms evening, favoring the I-90 region southward. Patchy fog developing. Lows 63-70. Dew point 60+. Wind SW 5-15 MPH, shifting to NW overnight.

SATURDAY: Sun/cloud mix. Highs 76-83, coolest coast. Dew point near 60. Wind N to NE 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 56-63. Dew point upper to middle 50s. Wind E under 10 MPH.

SUNDAY: Partly sunny. Highs 77-84, coolest coast. Dew point upper 50s to 60. Wind E to SE up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind S up to 10 MPH.

MONDAY: Sun/cloud mix. Highs 83-90 except cooler South Coast. Dew point 60+. Wind S 5-15 MPH.

MONDAY NIGHT: Partly cloudy. Patchy fog. Lows 63-70. Dew point 60+. Wind S up to 10 MPH.

TUESDAY: Partly cloudy. A late-day thunderstorm chance north and west. Highs 85-92, cooler South Coast. Dew point 60s. Wind SW 10-20 MPH.

DAYS 6-10 (AUGUST 31 – SEPTEMBER 4)

With uncertain timing of the next frontal boundary impacting the region will include the chance of showers/thunderstorms for August 31 with high humidity. Cooling/drying to start September as low pressure departs via eastern Canada and high pressure follows it, then later in the period shifts to the south allowing the region to warm up again.

DAYS 11-15 (SEPTEMBER 5-9)

No change from yesterday’s idea. There’s a little uncertainty in the pattern as some tropical activity from the western Pacific may have a hand in altering the pattern currently shown on medium range guidance. For now, calling for a mainly dry weather pattern with some up and down temperatures and only briefly unsettled weather at some point during the period.

C-19 Chat Post – 8-26-2022

DAYS 1-5 (AUGUST 25-29)

Pretty typical late summer weather will be ours as we head down the home stretch of August. First, high pressure provides a fair and warm day today with low to moderate humidity. This high slips offshore and the humidity comes up a bit, but shy of oppressive levels, on Friday. We’ll see a few air mass showers and thunderstorms start to pop up during the afternoon, and the approach of a cold front can help organize some of these showers and storms into line segments scattered around the area later in the day and into the evening hours. We’ll have to watch for a few strong to locally severe storms, but it will not be a widespread outbreak of severe weather. If you have outdoor plans, just keep a close watch on the sky and a reliable radar app if possible. The actual cold front will probably not clear the region until sometime early Saturday morning but I do think any shower activity will be limited to practically non-existent once the evening activity is gone. Saturday itself turns out to be a nice day, but noticeably cooler with a northerly to easterly air flow as high pressure bridges itself from the Great Lakes to northern Maine, centered in the St. Lawrence Valley. This high will bubble eastward and bring us an easterly to southeasterly air flow on Sunday, a day that will feature a few clouds but fair weather, a tiny increase in humidity (hardly noticeable), coolest but comfortable on the coast, and a little warmer over the interior away from the ocean’s effect. High pressure remains in control Monday, but centered to our east it will provide a southerly wind with a little more warmth and humidity here.

TODAY: Patchy clouds early morning interior southern MA and parts of CT/RI, otherwise mostly sunny, then additional cloud patches west to east later. Highs 82-89 except 75-82 Cape Cod & immediate coast. Wind variable up to 10 MPH with developing coastal sea breezes.

TONIGHT: Variably cloudy. Lows 61-68. Dew point nearing 60. Wind S to SW up to 10 MPH.

FRIDAY: Sun/cloud mix. Isolated to scattered afternoon showers and thunderstorms, favoring areas north and west of Boston. Highs 83-90. Dew point climbing through 60s. Wind SW 5-15 MPH.

FRIDAY NIGHT: Variably cloudy. Scattered showers and thunderstorms evening. Patchy fog and isolated showers overnight. Lows 63-70. Dew point 60+. Wind SW 5-15 MPH, shifting to NW overnight.

SATURDAY: Sun/cloud mix. Highs 76-83, coolest coast. Dew point near 60. Wind N to NE 5-15 MPH.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 56-63. Dew point upper to middle 50s. Wind E under 10 MPH.

SUNDAY: Partly sunny. Highs 77-84, coolest coast. Dew point upper 50s to 60. Wind E to SE up to 10 MPH.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 60-67. Dew point near 60. Wind S up to 10 MPH.

MONDAY: Sun/cloud mix. Highs 80-87 except cooler South Coast. Dew point 60+. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 30 – SEPTEMBER 3)

A shot of very warm to hotter air for the final 2 days of August, but the timing of a frontal boundary is uncertain for both showers and thunderstorms as well as an air mass change. There will be details to iron out. Dry weather for the first few days of September, starting cooler then warming up.

DAYS 11-15 (SEPTEMBER 4-8)

There’s a little uncertainty in the pattern as some tropical activity from the western Pacific may have a hand in altering the pattern currently shown on medium range guidance. For now, calling for a mainly dry weather pattern with some up and down temperatures and only briefly unsettled weather at some point during the period. Will iron out the details with time.

C-19 Chat Post – 8-25-2022

DAYS 1-5 (AUGUST 24-28)

After 2 days of unsettled weather the WHW forecast area has ended up with a pretty uneven rainfall distribution, and there is no real surprise about that. This is the nature of convective precipitation, and in a case where some of it was very heavy and occurred over similar areas during 2 days, some amounts were very heavy, 5+ inches in some cases, while other areas came away with modest amounts of under 1 inch. So in spot locations, flooding aside, we’ve seen some solid drought relief. Unfortunately, it was not regionwide relief, so we will still find ourselves in drought in general, and will need several more good episodes of precipitation going forward to lift us out of this drought – something that, as previously stated – needs time. You don’t want it all at once as it often does lead to flooding issues and other problems. But we got what we got, where we got it, and now we move on… Fair weather and the feel of summer returns over the next couple days. Today it warms up and is still a little on the humid side to start with drier air to come later. We still have a fair amount of clouds around to start, but these will reduce. However the atmosphere remains just unstable enough that a pop up shower or two can’t be ruled out mainly across interior locations, favoring north of I-90, this afternoon. As high pressure gains control, Thursday ends up quite warm but even less humid. A weak warm front may send some cloudiness into the region later Thursday and cannot rule out a shower at night with the front, leading to a summery day on Friday in the warm sector ahead of an approaching cold front. There’s still a few days to fine-tune the timing on that front but we will end up with a shower or thunderstorm threat from it, right now leaning toward late-day or evening/night and north and west of Boston, weakening as it pushes east and southeast through the early hours of Saturday, setting up what looks like a decent final weekend of August. High pressure’s position to our north would bring us somewhat cooler air and low humidity for Saturday then a slight up-tick in humidity as the high slides to a position east of New England by Sunday.

TODAY: Early to mid morning clouds dominate areas away from South Coast with more sun South Coast, then a sun/cloud mix with a slight chance of a pop up shower this afternoon interior locations. Highs 77-84. Dew point lowering from 60s to 50s. Wind variable to NW increasing to 5-15 MPH.

TONIGHT: Variably cloudy. Lows 58-65. Dew point 50s. Wind N up to 10 MPH.

THURSDAY: Sun much of day, more clouds late. Highs 78-85, coolest coast. Dew point 50s. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Mostly cloudy. A shower possible mainly well west and north of Boston. Lows 60-67. Dew point nearing 60. Wind SE to S up to 10 MPH.

FRIDAY: Sun/cloud mix. Late-day showers and thunderstorms possible, favoring areas north and west of Boston. Highs 83-90. Dew point lower to middle 60s. Wind SW 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. A shower or thunderstorm possible evening, may linger near the South Coast overnight. Lows 60-67. Dew point falling to upper 50s except 60+ South Coast. Wind shifting to NW 5-15 MPH.

SATURDAY: Sunny to partly cloudy. Highs 76-83, coolest coast. Wind N to NE 5-15 MPH.

SATURDAY NIGHT: Mostly clear. Lows 57-64. Wind E under 10 MPH.

SUNDAY: Partly sunny. Highs 77-84, coolest coast. Wind SE up to 10 MPH.

DAYS 6-10 (AUGUST 29 – SEPTEMBER 2)

Warm, some increase in humidity August 29-31, maybe a shower or thunderstorm with a frontal system around August 31. A shot of cooler air may be here in time to start September from Canadian high pressure.

DAYS 11-15 (SEPTEMBER 3-7)

Early indications are for high pressure to dominate much of this period with dry weather, starting seasonable then warming up. Maybe a little unsettled weather during the cooler to warmer transition.

C-19 Chat Post – 8-24-2022

DAYS 1-5 (AUGUST 23-27)

A pretty decent production of rainfall by the warm front portion of our low pressure system yesterday resulting in up to a few inches of rain in the jackpot areas of southeastern MA, especially Plymouth County. Other areas enjoyed the benefit of 0.50 to 1.50 inch but there were some “have-nots” that ended up under the 0.50 inch mark. Such is the nature of summertime rain. But in general, a helpful event for the drought. We’re far from ending it, but anything we get is definitely a positive. And some areas are in for more today. But this time the activity, associated with an approaching cold front, will be more in the form of classic showers and thunderstorms. After a morning that starts out with lots of clouds, areas of fog, and a cool mugginess, the wind will pick up and help clear us out at least somewhat, and enough to get some decent daytime heating. We’ll see some initial showers and possible thunderstorms pop up in a south southwest air flow well ahead of the cold front, and some of these can cause brief downpours. These will be around from midday through the first part of the afternoon. Later in the afternoon and into evening, a couple or a few clusters of showers and thunderstorms will have more of a west-to-east movement across our region, with activity most favored west of and up to the I-95 corridor, with less of a chance of the activity pushing into southeastern MA and RI before it has weakened and is in the process of dissipating. The frontal boundary will pass by the region by late evening but may linger a bit just offshore Wednesday, which will feature some additional clouds. Also, a little disturbance passing by to the north may trigger a couple isolated pop-up afternoon showers mainly over interior locations later in the day, but the probability of any location seeing that is very low. High pressure will dominate the weather Thursday with very warm, dry air. Friday, the high pushes offshore and a cold front approaches. It will be a very warm and slightly more humid day and with the approach of the front, add in the chance for a shower or thunderstorm, current timing favoring those being west and north of Boston later in the day with areas to the southeast only seeing remnant showers sometime in the evening or night. Either way, the front pushes through and high pressure from Canada builds to our north and sends a cooling north to northeast wind into our area to start the weekend, with fair weather.

TODAY: Variably cloudy. Scattered to numerous showers and possible thunderstorms during the afternoon, favoring areas in the I-95 corridor westward. Any storms can lead to brief road / parking lot flooding. Highs 77-84. Dew point upper 60s to near 70. Wind SW 5-15 MPH, can be variable and briefly gusty around any shower or storms.

TONIGHT: Mostly cloudy. Chance of showers. Patchy fog. Lows 60-67. Dew point falling to near 60. Wind W 5-15 MPH.

WEDNESDAY: Sun/cloud mix. Very slight shower threat interior areas afternoon. Highs 76-83. Dew point 50s. Wind NW 5-15 MPH.

WEDNESDAY NIGHT: Variably cloudy. Lows 58-65. Dew point 50s. Wind N up to 10 MPH.

THURSDAY: Partly cloudy. Highs 77-84, coolest coast. Dew point 50s. Wind variable up to 10 MPH with coastal sea breezes.

THURSDAY NIGHT: Mostly clear. Patchy ground fog overnight. Lows 60-67. Dew point upper 50s to 60. Wind SW up to 10 MPH.

FRIDAY: Sun/cloud mix. Late-day showers and thunderstorms possible, favoring areas north and west of Boston. Highs 83-90. Dew point lower to middle 60s. Wind SW 5-15 MPH.

FRIDAY NIGHT: Partly cloudy. A shower or thunderstorm possible evening. Lows 60-67. Dew point falling to upper 50s. Wind shifting to NW 5-15 MPH.

SATURDAY: Sunny to partly cloudy. Highs 77-84, coolest coast. Wind N to NE 5-15 MPH.

DAYS 6-10 (AUGUST 28 – SEPTEMBER 1)

Ironed out the uncertainty and August 28 looks like it will be a nice finish to the final weekend of August with high pressure shifting east of New England, fair weather and a southeasterly air flow, keeping the coast coolest while it warms nicely inland. Fair and slightly more humid weather August 29 and then we’ll watch for a frontal boundary to approach the region with a shower and thunderstorm threat sometime between late August 30 and late August 31 – timing uncertain, and a possible shot of cool/dry air to start September.

DAYS 11-15 (SEPTEMBER 2-6)

Early indications are for high pressure to dominate the first several days of September with dry weather, starting seasonable then warming up.

C-19 Chat Post – 8-23-2022

DAYS 1-5 (AUGUST 22-26)

Our best shot at beneficial rain to scratch the surface of the drought comes today as a warm front lifts toward and into the region ahead of advancing low pressure. A broad albeit weak trough of low pressure will help provide energy for this system, increasing the chance that at least a couple swaths of heavier rain and possible thunder occur with fairly widespread showers this afternoon and evening. My thinking is that a general 0.25 to 0.75 inch can be expected with spot amounts of 0.75 to over 1.00 inch are very possible. Some of the heavier rain can lead to quick areas of flooding, so keep that in mind if traveling. Once the warm front lifts through tonight, the rain chance dwindles to just a spot shower or thunderstorm in the warm sector, but what will be a relatively cooler (compared to the weekend) but humid day today will transition to a mild and muggy night. Tuesday, the low parenting the warm front will bring its sibling cold front across the region, triggering scattered showers and a few heavier thunderstorms. This does not look as widespread an event, nevertheless some heavy downpours are possible and can impact travel for brief times. The front will struggle to clear the area quickly and because of that some cloudiness may hang around Wednesday, so I’m not expecting complete clearing at this time. High pressure will push in though with dry weather returning including lower dew point air which will last through Thursday, a day that will feature more sun. On Friday, the high pushes offshore and we heat up a little bit with an increase in humidity, but an approaching cold front brings the chance of showers and thunderstorms later in the day. The timing and coverage of this activity is uncertain, but early indications are that it will lack good support and therefore have limited coverage.

TODAY: Cloudy. Areas of fog. Showers likely with embedded downpours and possible thunder from south to north during the afternoon and evening. Highs 72-79. Dew point middle 60s to 70. Wind SE 5-15 MPH.

TONIGHT: Mostly cloudy. Foggy areas. Isolated showers / thunderstorms possible. Lows 65-72. Dew point middle 60s to 70. Wind SW up to 10 MPH.

TUESDAY: Variably cloudy. Scattered showers and possible thunderstorms during the afternoon, favoring areas in the I-95 corridor westward. Highs 77-84. Dew point upper 60s to near 70. Wind SW 5-15 MPH, can be variable and briefly gusty around any shower or storms.

TUESDAY NIGHT: Mostly cloudy. Chance of showers. Patchy fog. Lows 60-67. Dew point falling to near 60. Wind W 5-15 MPH.

WEDNESDAY: Mostly cloudy. Highs 76-83. Dew point 50s. Wind NW 5-15 MPH.

DAYS 6-10 (AUGUST 27-31)

There is a little uncertainty in the forecast for the final weekend of August (27-28) with disagreement in the medium range guidance. Leaning toward a sun/cloud mix Saturday (27) with lower dew points, and more humid air and cloud cover for Sunday (28) but not sure yet if showers will threaten. Fine-tuning of this outlook will take place as the week goes on. With uncertainty to start this period, there is obviously some beyond that as well and we’ll be watching for a frontal boundary to approach and pass the region sometime in the last few days of the month with a shower and thunderstorm threat.

DAYS 11-15 (SEPTEMBER 1-5)

Early indications are for high pressure to dominate the first several days of September with dry weather, starting seasonable then warming up, and a chance of some unsettled weather by the end of the period.
