DAYS 1-5 (JUNE 27 – JULY 1)

A cold front moves across the region to start the week with our only real chance of rain during the next 5 days. I don’t think we’ll see much in the way of heavy thunderstorm activity – probably just some embedded areas of heavy showers and possible thunder in a more general widespread light to moderate shower area. We don’t have enough time for decent heating as extensive cloud cover was already moving into the region to start the day, and there are a couple of other limiting factors in terms of helping bigger storms develop. The slow but steadily moving front slides offshore tonight. Dry Canadian air arrives for Tuesday – a very nice day but with a breeze. High pressure overhead brings another nice day Wednesday, but a much weaker field field will allow the development of coastal sea breezes. A weak disturbance will move across the region quick from west to east Wednesday night with some cloudiness and perhaps a passing shower, but high pressure moves back in for Thursday – a very nice summer day to end June. This high will slide offshore and it looks like the heat will be on to welcome the month of July on Friday.

TODAY: Mostly cloudy. Isolated to scattered showers through mid morning. Widespread showers and possible embedded thunderstorms late morning to late afternoon. Highs 73_80. Humid – dew point middle to upper 60s. Wind SW 10-20 MPH, shifting to W from west to east across there region during the afternoon.

TONIGHT: Mostly cloudy evening with additional showers possible favoring RI and southeastern MA. Clearing overnight. Lows 56-63. Drying out with dew point falling to lower 50s. Wind W 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 75-82. Dew point lower 50s. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 55-62. Wind variable under 10 MPH.

WEDNESDAY: Sunny to partly cloudy. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Variably cloudy. Chance of a passing shower. Lows 60-67. Wind SW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 78-85. Wind W 5-15 MPH.

THURSDAY NIGHT: Mostly clear. Lows 58-65. Wind WSW up to 10 MPH.

FRIDAY: Mostly sunny. Highs 88-95, cooler South Coast. Wind SW 5-15 MPH.

DAYS 6-10 (JULY 2-6)

Warm/humid July 2 with a cold front bringing a shower/t-storm threat – timing on that is uncertain but any interruption to fair weather will likely be brief. A northwesterly air flow arrives for July 3-4 with fair weather and drier air and that high should hang around with dry weather and a warm-up for the end of the period.

DAYS 11-15 (JULY 7-11)

We may be vulnerable to showers/thunderstorms in the July 7-8 period as we’ll be near an air mass boundary with some disturbances moving through. The longer range call is for fair weather to return for the July 9-10 weekend as well as the end of the period.

DAYS 1-5 (JUNE 26-30)

The feel of summer arrived just in time for the first weekend of summer. Yesterday featured lots of sun, temperature in the 80s in general, with some inland locations making runs at 90 while the coast cooled back to the 70s with an afternoon sea breeze. Today will be a touch warmer overall but we still may see some coastal sea breezes, with inland penetration a little less than yesterday. So overall a slightly warmer to hotter day is today’s takeaway. Humidity levels will be in check with dew points hovering around 60 – a bit humid for some folks, but definitely not oppressive. Ironically as the temperature comes down for Monday due to cloud cover with the arrival and passage of a slow-moving cold front, the humidity will spike ahead of the front, so it’ll be cooler but more humid. Add into that a decent chance at fairly widespread showers and possible embedded thunderstorms. The thunderstorm threat is likely to be limited due to the lack of daytime heating from extensive cloud cover, and slow-moving nature of the front, which will tend to produce more general showers. Behind the front, we get a delivery of pleasant Canadian air for Tuesday. High pressure moves overhead Wednesday with nice weather – light winds and coastal sea breezes. We’ll have a weak disturbance move quickly west to east across the region Wednesday night with some clouds and possibly a passing shower, and then another high pressure area moves in with great summer weather for Thursday, the final day of June.

TODAY: Mostly sunny. Highs 78-85 coast, 86-93 inland. Dew point upper 50s to lower 60s. Wind S-SW up to 10 MPH with some local sea breeze eastern shores.

TONIGHT: Partly cloudy. Patchy fog. Lows 62-69. More humid, dew point lower to middle 60s. Wind SW 5-15 MPH.

MONDAY: Mostly cloudy. Patchy fog early. Showers likely and a chance of thunderstorms midday-afternoon. Highs 75-82, coolest South Coast. Humid – dew point middle to upper 60s. Wind SW 10-20 MPH, shifting to W by late.

MONDAY NIGHT: Mostly cloudy evening with additional showers possible favoring RI and southeastern MA. Clearing overnight. Lows 56-63. Drying out with dew point falling to lower 50s. Wind W 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 75-82. Dew point lower 50s. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 55-62. Wind variable under 10 MPH.

WEDNESDAY: Sunny to partly cloudy. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

WEDNESDAY NIGHT: Variably cloudy. Chance of a passing shower. Lows 60-67. Wind SW 5-15 MPH.

THURSDAY: Mostly sunny. Highs 78-85. Wind W 5-15 MPH.

DAYS 6-10 (JULY 1-5)

High pressure shifts offshore with fair weather and summer heat for July 1. Warm/humid July 2 with a cold front bringing a shower/t-storm threat – timing on that is uncertain but any interruption to fair weather will likely be brief. A northwesterly air flow arrives for July 3-4 with fair weather and drier air and that high should hang around with dry weather and a warm-up for the end of the period.

DAYS 11-15 (JULY 6-10)

We may be vulnerable to showers/thunderstorms in the July 6-8 period as we’ll be near an air mass boundary with some disturbances moving through. The longer range call is for fair weather to return for the July 9-10 weekend, but that’s way into the future so the confidence on that forecast is not all that high at this point.

DAYS 1-5 (JUNE 25-29)

In stark contrast to the final weekend of spring (June 18-19), which featured anomalously cool and breezy weather with a lot of cloud cover at times, and an episode of showery weather mid weekend, this first weekend of summer will feature dry weather, moderate humidity, lots of sun both days, and a will be on the hot side – not super hot, but hot enough for most folks. High pressure will be in control, with the center of the high drifting eastward from the Middle Atlantic States to a position off the East Coast. Today’s wind field will be weak enough to allow a sea breeze to easily develop, and cool down coastal areas and for up to a few miles inland too. Tomorrow’s wind field will be a little bit stronger from the southwest, which is a wind off the water for the South Coast, Cape Cod, and parts of Cape Ann, so those will be your coolest areas. But other portions of the eastern shoreline can still see a sea breeze develop for part of the midday and afternoon hours as well. If Boston is going to reach 90 for the first time this year, it’s going to happen on Sunday, as I’m pretty confident a sea breeze will prevent it today. Tomorrow, even if we see the sea breeze there, they have a shot to reach 90 either before it happens or late in the day when it likely quits. So that might be the “most exciting” to track with the weather this weekend, since there is pretty much a zero shower / t-storm threat with the atmosphere being too stable, despite the heating up of the atmosphere. Things change Monday when a cold front slides into and across the region. While this is not likely to be a particularly fast-moving front, it will be moving along, and I feel that the timing of the front will be early enough in the day to prevent the strongest possible thunderstorms from forming. It’ll also present a great deal of cloudiness starting very early in the day, limiting heating, so it’ll end up about 10 degrees cooler than the weekend days, but more humid up until the front goes by. Will we get a widespread rainfall out of this? It’s possible, because we may see a solid band of showers, but it won’t be around for all that long and it being our only real chance of rain during this 5-day period, any benefit for our rainfall deficit and evolving drought situation will be limited. A cooler, drier air mass moves in for Tuesday with high pressure approaching the region, and the high center, while weak, will be right over our region with fair weather Wednesday – a day that would feature a bit of an inland warm-up while coastal areas see a sea breeze. We may see a bit more cloudiness later Wednesday pending the timing of an approaching disturbance from the west. At day-5 that’s a little difficult to pin down as it will likely be a very small, weak, and fast-moving feature.

TODAY: Sunny. Highs 77-84 coast, 84-91 inland. Dew point upper 50s to near 60. Wind variable up to 10 MPH with coastal sea breezes.

TONIGHT: Mostly clear. Patchy ground fog in lower elevations. Lows 61-68. Dew point upper 50s to lower 60s. Wind S under 10 MPH.

SUNDAY: Mostly sunny. Highs 79-86 coast, 86-93 inland. Dew point lower 60s. Wind S-SW up to 10 MPH with some local sea breeze eastern shores.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. More humid, dew point lower to middle 60s. Wind SW 5-15 MPH.

MONDAY: Mostly cloudy. Patchy fog early. Showers likely and a chance of thunderstorms midday-afternoon. Highs 75-82, coolest South Coast. Humid – dew point middle to upper 60s. Wind SW 10-20 MPH, shifting to W by late.

MONDAY NIGHT: Mostly cloudy evening with additional showers possible favoring RI and southeastern MA. Clearing overnight. Lows 56-63. Drying out with dew point falling to lower 50s. Wind W 5-15 MPH.

TUESDAY: Sun and passing clouds. Highs 75-82. Dew point lower 50s. Wind W 5-15 MPH.

TUESDAY NIGHT: Clear. Lows 55-62. Wind variable under 10 MPH.

WEDNESDAY: Sunny to partly cloudy. Highs 77-84, coolest coast. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 30 – JULY 4)

High pressure will be the main controlling factor in the weather heading into and through the holiday weekend with mainly dry weather. A warming trend comes early in the period (June 30 / July 1), a weak frontal system comes through at some point around July 2 with the only shower / t-storm threat foreseen, and probably brief at that, and then a Canadian air mass arrives for the latter portion of the period, based on current timing expectations.

DAYS 11-15 (JULY 5-9)

A little more hinting at reinforcing cooler air from Canada on some guidance while other guidance shows a more seasonable westerly flow, so there is some uncertainty here. What I am fairly confident of at this point is that we stay in a mostly dry weather pattern.

C-19 Chat Post – 6-25-2022

DAYS 1-5 (JUNE 24-28)

We’re finally about to get rid of the weather pattern that was causing the atmosphere to be confused about which way to send weather systems. Today, a low pressure circulation that was sitting nearby departs the area as things start to move from west to east again, but there is enough instability about that we will probably see a few afternoon showers popping up again, like yesterday. Unlike yesterday, these will be moving pretty much in the opposite direction (yesterday’s drifted from south to north, today’s will have a more north-to-south motion). The weekend outlook is a good one if you like the feel of summer, and hey, it’s just in time for the first weekend of astronomical summer. What great timing! We’ll have high pressure in control with a general southwesterly air flow but the high will be weak enough that some coastal sea breezes can still take place each day, while some inland areas make runs at 90 both days. Sunshine will be dominant during each day and the threat of any pop showers or thunderstorms will be nearly non-existent. Things change on Monday, however, as a cold front moves slowly across the region bringing our best chance of widespread shower and thunderstorm activity during this 5-day period. Timing of the system looks like it will produce most of the rainfall threat during the afternoon, but may need to adjust that a little bit as we get closer to it. Tuesday, a cooler and drier air mass is due to move in behind that front.

TODAY: Sun/cloud mix. A passing shower possible during the afternoon. Highs 75-82, coolest coast. Wind variable to SE up to 10 MPH.

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

SATURDAY: Mostly sunny to partly cloudy. Highs 82-89 except 75-82 coast. Dew point 60+. Wind S up to 10 MPH with coastal sea breezes.

SATURDAY NIGHT: Mostly clear. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

SUNDAY: Mostly sunny to partly cloudy. Highs 83-90 except cooler coast. Dew point 60+. Wind SW up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Chance of showers and thunderstorms, especially in the afternoon. Highs 78-85. Dew point 60+. Wind SW 10-20 MPH.

MONDAY NIGHT: Mostly cloudy. Chance of showers in the evening. Patchy fog. Lows 58-65. Lowering humidity. Wind W 5-15 MPH, diminishing.

TUESDAY: Sun/cloud mix. Highs 75-82. Wind 5-15 MPH.

DAYS 6-10 (JUNE 29 – JULY 3)

High pressure is expected to dominate with mostly fair weather for much of this period, temperatures warming to near to perhaps slightly above normal. There may be a weak disturbance or frontal system around at some point around the middle of the period to bring a brief shower and thunderstorm chance.

DAYS 11-15 (JULY 4-8)

Seasonably warm weather with high pressure in control most of the time. One or two shower or thunderstorm chances may occur but pattern looks mainly dry. Shower / thunderstorm threat may increase later in the period.

DAYS 1-5 (JUNE 23-27)

Even unsettled weather isn’t that unsettled in the pattern we are in. If you are familiar with our weather here, and most of you reading this are very familiar with it, if you hear talk of omega blocks and low pressure nearby, and a warm front trying to move in but not quite making it, it likely makes you think of stretches of cloudy, wet weather. But we are experiencing that pattern right now, and other than “on the edge” kind of unsettled weather, the pattern fails to deliver. Ironically we need it too as you know, since we are in a building drought situation. But even what looked kind of promising a couple days ago – low pressure bringing us some rainfall during today – is not going to pan out. Yeah the low is out there, and the warm front is still trying to move in, but failed so badly that it actually moved further away (technically a cold front pushing further inland over the interior Northeast). So now we stand only the risk of a few isolated showers popping up today and have to look to Monday as our next chance of rainfall, and that will be dependent on how much moisture can be wrung out of the atmosphere by a cold front moving into the region. Before we get there, we do finally see a transition from today’s now dry forecast and continued cool air to the feel of summer for the first weekend of summer and the last weekend of June. This will take place as the aforementioned blocking pattern breaks down and allows things to move more from west to east once again, eventually putting an area of high pressure south and southeast of New England, allowing us to warm up. But even in that warm-up, with still chilly ocean water we will see the coastal areas cooler than inland locations. But it does indeed look like a great weekend for outdoor activities, so that’s a plus!

TODAY: Sun/cloud mix. A few isolated showers possible. Highs 67-74, coolest coast. Wind E 5-15 MPH.

TONIGHT: Variably cloudy. Lows 54-61. Wind E up to 10 MPH.

FRIDAY: Partly sunny. Highs 75-82, coolest coast. Wind SE up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Patchy fog. Lows 60-67. Wind S up to 10 MPH.

SATURDAY: Partly cloudy. Highs 81-88 except 73-80 coast. Dew point 60+. Wind S up to 10 MPH with coastal sea breezes.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

SUNDAY: Partly sunny. Highs 83-90 except cooler coast. Dew point 60+. Wind S up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind S up to 10 MPH.

MONDAY: Mostly cloudy. Chance of showers and thunderstorms, especially in the afternoon. Highs 76-83. Dew point 60+. Wind SW 10-20 MPH.

DAYS 6-10 (JUNE 28 – JULY 2)

High pressure is expected to dominate with mostly fair weather for much of this period, starting cooler than turning warmer again. There may be a weak disturbance or frontal system around at some point late in the period to bring a brief shower and thunderstorm chance.

DAYS 11-15 (JULY 3-7)

Seasonably warm weather with high pressure in control most of the time. One or two shower or thunderstorm chances may occur but pattern looks mainly dry.

C-19 Chat Post – 6-23-2022

DAYS 1-5 (JUNE 22-26)

While some eastern coastal areas saw the sun rise and have sun still, much of the region is blanketed by clouds as we start the day. These clouds are triggered by a warm front that’s trying to push across the region, but can’t do it, and in fact will be moving back the other way as the entire pattern retrogrades or moves westward during the next day and a half. This will help clear us out more today and then will bring back our old friend, the weekend low pressure area, but in weaker form, for Thursday. This brings us some chance of showers Thursday, but this event, in terms of rain, looks unimpressive. Things start to move “the right way” as a zonal flow returns Friday through the weekend, finally allowing some much warmer weather to arrive in time for the first weekend of summer.

TODAY: Lots of clouds to start (most sun eastern coast), including some periodic showers through midday in southwestern NH and parts of central MA to eastern CT, then more sun and less clouds from east to west as the day goes on. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

TONIGHT: Partly to mostly cloudy. Chance of showers overnight. Lows 56-63. Wind SE up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers. Highs 66-73, coolest coast. Wind SE to E up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Chance of showers early. Lows 55-62. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 75-82, coolest coast. Wind SE to S up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Highs 81-88 except 73-80 coast. Dew point 60+ Wind S up to 10 MPH with coastal sea breezes.

SATURDAY NIGHT: Partly cloudy. Patchy fog. Lows 62-69. Dew point 60+. Wind SW up to 10 MPH.

SUNDAY: Partly sunny. Highs 83-90 except cooler coast. Dew point 60+. Wind S up to 10 MPH with coastal sea breezes.

DAYS 6-10 (JUNE 27 – JULY 1)

Look for a frontal system to bring a chance of showers/thunderstorms early in the period, then high pressure to dominate with dry weather for the balance of the period, cooler at first, then warming.

DAYS 11-15 (JULY 2-6)

Signs of a dry and seasonably warm to very warm stretch of weather for early July with high pressure in control much of the time. Will probably deal with one frontal passage during this period of time with limited shower / t-storm threat.

C-19 Chat Post – 6-22-2022

DAYS 1-5 (JUNE 21-25)

The summer solstice occurred this morning at 5:13 a.m. and the first day of summer will be a nice one, with high pressure in control, keeping advancing clouds mostly at bay. This is part of the same pattern we’ve been in for a number of days now – a fairly blocked atmosphere with not a lot of progression. In fact, retrogression (westward movement) of features becomes a player in this forecast. While a northwest to north air flow sends clouds into the region, the start of a retrogression of the pattern first sends a bubble of high pressure westward and keeps the clouds from overtaking the region for long stretches of time. In fact, an area of rain that will try to move in early Wednesday will also be largely thwarted, save for a possible shower early in the day favoring western portions of the WHW forecast area. So for the most part, both today and Wednesday will be nice days if you can deal with some clouds at times. But eventually the westward movement of features will get us into unsettled weather, as the low pressure area that plagued us with cool air, cloudiness, some showers, and a gusty breeze over the weekend will make its return for an unsettled day on Thursday. This time though it looks like just a short-stay, and it should be on its way out by Friday as things start to move to the east again. This will also set us up for a nice start to the first full weekend of summer.

TODAY: More sun than clouds. Highs 68-73 coast, 73-78 inland. Wind variable up to 10 MPH with coastal sea breezes.

TONIGHT: Mostly cloudy. Pre-dawn rain possible southwestern NH, cetnral MA, and eastern CT, possibly western RI. Lows 51-58. Wind SE up to 10 MPH.

WEDNESDAY: More clouds than sun. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Rain developing. Lows 56-63. Wind E up to 10 MPH.

THURSDAY: Cloudy. Periods of rain. Areas of fog. Highs 66-73, coolest coast. Wind E up to 10 MPH.

THURSDAY NIGHT: Rain ends, clouds break, patchy fog lingers. Lows 55-62. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 75-82. Wind S up to 10 MPH.

FRIDAY NIGHT: Partly cloudy. Lows 60-67. Wind SW up to 10 MPH.

SATURDAY: Partly cloudy. Highs 78-85. Wind SW 5-15 MPH.

DAYS 6-10 (JUNE 26-30)

Down the home stretch of June we go during this period, and it looks like a largely dry pattern with only one rain threat. We start warm and moderately humid to end the weekend June 26. A cold front brings the chance of showers and thunderstorms June 27. High pressure settles in with fair weather for the middle of next week, cooler at first, then moderating.

DAYS 11-15 (JULY 1-5)

Signs of a dry and seasonably warm to very warm stretch of weather for early July with high pressure in control much of the time. Will probably deal with one frontal passage during this period of time with limited shower / t-storm threat.

C-19 Chat Post – 6-21-2022

DAYS 1-5 (JUNE 20-24)

We’re in the last 24 hours of astronomical spring, with the summer solstice occurring at 5:13 a.m. Tuesday, but don’t think that just because the calendar officially says “summer” that we will immediately experience full summer weather. It’s still going to be a struggle to get us there as our weather pattern recently, while not excessively wet, has certainly not been all that warm either, especially during this past weekend when we had some anomalous chill. But we do get rid of that somewhat right away as we start the new week. Today will be a bright and milder day, governed by high pressure, but light wind will allow a sea breeze so the coast will be cooler. A warm front will approach from the west Tuesday and Wednesday, but never quite get here. It will result in some areas of clouds at times, especially Tuesday night and Wednesday. Some onshore flow may add enough low level moisture from some lower clouds and patchy fog Tuesday night and early Wednesday as well, but at this point I don’t think any precipitation will occur, even though the front gets rather close Wednesday. By Wednesday night and into Thursday, however, things change a little. Although the frontal boundary gets pulled back to the south and west somewhat, a low pressure area is expected to develop offshore and should be in a position to deliver some rain to us during that time frame. This low will actually be triggered by another block-up in the atmosphere and a retrogression (westward movement) of the upper low that plagued us over the weekend. But this time it won’t hang around nearly as long, and it should be back on the move to the east by Friday, with improvement here. To be honest, while people tend to frown upon wet weather as we get to summer, any ran we can squeeze out of the pattern is good, as we continue to run a deficit for the year and experience longer term abnormally dry to moderate drought conditions across a fair amount of the WHW forecast area.

TODAY: Mostly sunny. Highs 65-70 coast, 70-75 inland. Wind variable up to 10 MPH with coastal sea breezes.

TONIGHT: Mostly clear. Lows 48-55. Wind variable under 10 MPH.

TUESDAY: More sun than clouds. Highs 68-73 coast, 73-78 inland. Wind variable up to 10 MPH with coastal sea breezes.

TUESDAY NIGHT: Mostly cloudy. Lows 51-58. Wind SE up to 10 MPH.

WEDNESDAY: More clouds than sun. Highs 68-73 coast, 73-78 inland. Wind SE up to 10 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Rain developing. Lows 56-63. Wind E up to 10 MPH.

THURSDAY: Cloudy. Periods of rain. Areas of fog. Highs 66-73, coolest coast. Wind E up to 10 MPH.

THURSDAY NIGHT: Rain ends, clouds break, patchy fog lingers. Lows 55-62. Wind variable under 10 MPH.

FRIDAY: Partly sunny. Highs 75-82. Wind S up to 10 MPH.

DAYS 6-10 (JUNE 25-29)

June 25-26 weekend looks seasonably warm and a little more humid with a south to southwest air flow. We may see a couple showers and thunderstorms with the increased moisture combined with sun’s heating, but overall it looks like a rain-free weekend. A frontal system from the west brings a better opportunity for showers/thunderstorms about June 27 possibly into June 28 before a push of drier and slightly cooler air for later in the period.

DAYS 11-15 (JUNE 30 – JULY 4)

Signs of a dry and seasonably warm to very warm stretch of weather for the end of June and beginning of July with high pressure in control.
