DAYS 1-5 (AUGUST 19-23)

Two systems of tropical origin have some impact on our weather the next 5 days. First, the remains of what was once Tropical Storm Fred pass through our region today from southwest to northeast, in the form of a weak low pressure area, but with plenty of moisture. It will produce a couple rounds of showers, the first being a pretty solid batch of rainfall, steadiest I-90 northward, a little more showery to the south. Keep in mind that the low level wind shear associated with systems like this can sometimes lead to brief, usually weak tornadoes occurring with some of the convective cells. These can lead to locally damaging winds and this is a slight possibility during the morning and midday hours as the first batch of showers comes across the region. Also, some localized flooding may occur with heavier rain in poor drainage areas. The second shower batch will be more in the form of a scattered shower area moving through as the low center gets ready to pull away later on, and this system will have made its exit by tonight. A small area of high pressure sneaks in behind it for Friday, which will likely be a rain-free day with the exception of a possible pop up shower, and it will be warm and quite humid. A back-door cold front will slip down from the northeast this weekend with a bit of a cooling trend and a slight drop in the humidity. Our attention will be on Henri, forecast to be a category 1 hurricane south of New England by later in the weekend. There is still a significant deal of uncertainty with the eventual track of this system and its impact on SNE. My advice is to be prepared for an impact while keeping in mind that we may still be impacted minimally. This is all going to depend on the track and strength details, which will reveal themselves the next couple of days. Subtle details of strength of high pressure ridging to the north of the system and a trough of low pressure approaching from the west will have the final say in this, so for now my forecast will reflect the potential for rainfall from the system later Sunday into Monday, with some wind.

TODAY: Mainly cloudy. Numerous to widespread showers and possible thunderstorms morning-midday southwest to northeast across the region. Scattered showers and thunderstorms west to east again later in the day. Highs 75-82. Dew point upper 60s to middle 70s. Wind S up to 10 MPH. Briefly stronger wind gusts are possible in some showers and storms.

TONIGHT: Mostly cloudy. Slight chance of a passing shower this evening. Patchy fog. Lows 67-74. Dew point upper 60s to lower 70s. Wind SW up to 10 MPH.

FRIDAY NIGHT: Variably cloudy. Areas of fog. Lows 65-72. Dew point upper 60s. Wind SW under 10 MPH.

SATURDAY: Partly sunny. Highs 78-85, coolest coast. Dew point upper to middle 60s. Wind SW up to 10 MPH shifting to E during the day.

SATURDAY NIGHT: Variably cloudy. Patchy fog. Lows 62-69. Dew point middle to lower 60s. Wind E under 10 MPH.

SUNDAY: Mostly cloudy. Rain is possible mainly later in the day favoring southern areas. Areas of fog.Highs 72-79. Dew point middle to upper 60s. Wind E to NE 5-15 MPH, may be stronger South Coast region later in the day.

SUNDAY NIGHT: Cloudy with periods of rain and a chance of thunderstorms. Fog likely. Lows 63-70. Dew point middle to upper 60s. Wind E to NE 10-20 MPH and gusty, may be stronger especially in coastal areas.

DAYS 6-10 (AUGUST 24-28)

A trough moving through from the west brings the chance of additional shower and thunderstorm activity August 24 possibly into August 25 before high pressure builds in with dry and seasonably warm weather thereafter.

DAYS 11-15 (AUGUST 29 – SEPTEMBER 2)

High pressure is expected to dominate, with limited rain chances and fairly warm weather.

C-19 Chat Post – August 19 2021

DAYS 1-5 (AUGUST 18-22)

Yes, I am aware that some operational runs of a particular model bring Henri as a Category 1 hurricane to a southern New England landfall. But I am also aware that the majority of models’ operational runs and all model ensemble means do not indicate this scenario. My advice: Don’t board the hype train, but pay attention to future forecasts from mets and the NHC. Right now, this is a system that would have its closest pass not before day 5. We have a long way to go. In the mean time, let’s focus on the nearer term. That starts with the arrival of the muggy air today, but with lots of clouds. We won’t see the heat we saw with the high humidity last week, just typical warmth of August as we go through the next few days. Before we have to worry about whatever Henri does (or doesn’t do) to us, we have the remains of Fred coming along to bring us some wet weather. But that isn’t really going to happen until tomorrow, leaving today mostly rain-free with limited shower activity mostly well west and north of Boston. It appears that the track of this system’s remnants, in the form of a weak low pressure area, will be far enough north that here in the WHW forecast area we’ll experience a couple rounds of showers/downpours, with the heaviest rain occurring in areas to our west and north.. Also, expecting a diminished rainfall threat for the end of the week after these remains move away from our region. At this time, I am keeping Sunday’s forecast basically the same as I had yesterday, and we will closely monitor the behavior of Henri, making adjustments in the forecast if needed. Other than focusing on the rough surf that will take place starting this weekend (into early next week), we may not need to change much else. “Stay tuned…”

TODAY: Mostly cloudy. A few showers possible mainly southwestern NH, central MA, and eastern CT. Highs 78-85, coolest South Coast. Dew point middle to upper 60s. Wind S up to 10 MPH.

TONIGHT: Mostly cloudy. Isolated showers. Patchy fog. Lows 65-72. Dew point middle to upper 60s. Wind S up to 10 MPH.

DAYS 6-10 (AUGUST 23-27)

Rainfall threat for August 23 will depend on the track of Henri and an approaching low pressure disturbance and frontal system from the west. Additional showers mostly from the system from the west August 24. Generally drier and seasonably warm weather August 25-27.

DAYS 11-15 (AUGUST 28 – SEPTEMBER 1)

High pressure is expected to dominate, with limited rain chances and fairly warm weather.

C-19 Chat Post – August 18 2021

DAYS 1-5 (AUGUST 17-21)

A warm front will approach and pass through our region today and tonight. The clouds will be abundant, shower activity with this front will not be, staying mostly west and north of the region. The front will introduce much higher humidity for the rest of this week, along with a better opportunity for shower activity. The peak of this shower activity appears to be set to occur later Thursday through early Friday, associated with the remnants of Tropical Storm Fred. After that, the axis of most concentrated moisture should push offshore with a diminishing though not disappearing shower threat for the balance of Friday. A push of high pressure from eastern Canada may kill the shower chance by early Saturday to start the weekend.

TODAY: Partly sunny. Highs 78-85, coolest coast. Dew point lower 60s. Wind SE up to 10 MPH.

TONIGHT: Mostly cloudy. Fog patches. Slight chance of a shower. Lows 63-70. Dew point lower to middle 60s. Wind SE to S up to 10 MPH.

WEDNESDAY: Mostly cloudy. A few showers possible mainly southwestern NH, central MA, and eastern CT. Highs 78-85, coolest South Coast. Dew point middle to upper 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Chance of showers mainly CT/RI. Patchy fog. Lows 65-72. Dew point middle to upper 60s. Wind S up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers in the morning. Showers likely with a chance of thunderstorms in the afternoon. Highs 75-82. Dew point upper 60s to lower 70s. Wind S up to 10 MPH.

THURSDAY NIGHT: Cloudy. Numerous showers and possible thunderstorms. Areas of fog. Lows 67-74. Dew point upper 60s to lower 70s. Wind S up to 10 MPH.

FRIDAY: Mostly cloudy. Best chance of showers during the morning, diminishing during the afternoon. Highs 75-82. Dew point upper 60s to lower 70s. Wind variable up to 10 MPH.

FRIDAY NIGHT: Mostly cloudy. Areas of fog. Lows 65-72. Dew point upper 60s. Wind variable under 10 MPH.

SATURDAY: Mostly cloudy to partly sunny. Slight chance of a shower. Highs 75-82, coolest coast. Wind E up to 10 MPH.

DAYS 6-10 (AUGUST 22-26)

Light onshore flow but only a small shower chance with coolest air along the coast for August 22 to end the weekend. We also have to keep an eye out for TS Henri offshore. While most guidance has it staying offshore between New England and Bermuda, it will be close enough to create rough surf along the coast and may be close enough to push a band or two of showers into far southeastern New England at some point, most likely August 23. Front from the west may bring showers August 24 before a drying trend and high pressure moving in later in the period with seasonably warm air.

DAYS 11-15 (AUGUST 27-31)

High pressure is expected to dominate, with limited rain chances and fairly warm weather to end August.

C-19 Chat Post – August 17 2021

DAYS 1-5 (AUGUST 16-20)

High pressure overhead now will shift offshore through Tuesday and a warm front will approach the region later Tuesday. During the next two days there will be some high and mid level clouds around, though limited to mostly this morning during today before becoming more widespread Tuesday. The warm front will cross the region Tuesday night and introduce higher humidity for Wednesday through Friday. In addition, a couple disturbances including the remains of what was once Tropical Storm Fred will be pushed into our region, increasing the chance of shower activity, though the chance will not be that great and will be mostly over interior areas Wednesday before peaking on Thursday and continuing into Friday before diminishing later Friday.

TODAY: Partly cloudy morning. Sunny afternoon. Highs 75-82, coolest coast. Dew point middle 50s. Wind N to E up to 10 MPH..

TONIGHT: Mostly clear evening. Variably cloudy overnight. Patchy fog interior lower elevations. Lows 57-64. Dew point upper 50s. Wind E to SE under 10 MPH.

TUESDAY: Partly sunny. Highs 78-85, coolest coast. Dew point lower 60s. Wind SE up to 10 MPH.

TUESDAY NIGHT: Mostly cloudy. Fog patches. Slight chance of a shower. Lows 63-70. Dew point lower to middle 60s. Wind SE to S up to 10 MPH.

WEDNESDAY: Mostly cloudy. A few showers possible mainly southwestern NH, central MA, and eastern CT. Highs 78-85, coolest South Coast. Dew point middle to upper 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Chance of showers mainly CT/RI. Patchy fog. Lows 65-72. Dew point middle to upper 60s. Wind S up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers and possibly a few thunderstorms. Highs 75-82. Dew point upper 60s to lower 70s. Wind S up to 10 MPH.

THURSDAY NIGHT: Mostly cloudy. Scattered to numerous showers and possible thunderstorms. Areas of fog. Lows 67-74. Dew point upper 60s to lower 70s. Wind S up to 10 MPH.

FRIDAY: Mostly cloudy to partly sunny. Chance of showers and possibly a thunderstorm until late in the day. Highs 75-82. Dew point upper 60s to lower 70s.

DAYS 6-10 (AUGUST 21-25)

There is a little uncertainty in the forecast for the August 21-22 weekend. Expecting the main plume of tropical moisture to have shifted offshore, reducing the chance of showers from that, but a weak upper low over the Great Lakes trying to move into New England with additional shower opportunities, while high pressure to the north may do its part to send somewhat drier air into the region. Putting this together, leaving a slight chance of showers in, favoring Saturday, warmest and highest humidity day being Saturday with slightly cooler and less humid air arriving Sunday. Fine-tuning is going to be needed for that forecast as we go along this week. Based on the anticipated weekend scenario and the guidance that shows it best, will go for dry weather August 23 then slightly higher humidity and a return to the chance of some shower activity August 24 with dry air again attempting to move back into the region for the end of the period.

DAYS 11-15 (AUGUST 26-30)

The guidance trend says the East Coast has a little less to worry about regarding potential tropical systems, but always keeping an eye out there. High pressure should be the dominant player with mostly rain-free weather and near to above normal temperatures.

C-19 Chat Post – August 16 2021

DAYS 1-5 (AUGUST 15-19)

An area of high pressure will control our weather through Tuesday. Its center will determine our wind direction and humidity level, the latter of which will be rather low through 48 hours and only going up a little bit as the high shifts offshore Tuesday, so overall three very comfortable days ahead for mid August. When we get to the middle of the week, it will be time for the return of higher humidity, cloudiness, and eventually the threat of showers as tropical moisture begins to flow into the region from the south.

TODAY: Sunny. Highs 77-84, coolest coast. Dew point near 60 South Coast early otherwise 50s. Wind N to variable up to 10 MPH with coastal sea breezes.

TONIGHT: Mostly clear. Patchy ground fog lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind variable to N under 10 MPH.

MONDAY: Sunny. Highs 76-83, coolest coast. Dew point middle to upper 50s. Wind N to E up to 10 MPH.

MONDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 57-64. Dew point upper 50s. Wind variable under 10 MPH.

TUESDAY: Partly cloudy. Highs 78-85, coolest South Coast. Dew point upper 50s to 60. Wind variable up to S 10 MPH with coastal sea breezes.

TUESDAY NIGHT: Variably cloudy. Patchy fog. Lows 61-68. Dew point lower 60s. Wind S up to 10 MPH.

WEDNESDAY: Mostly cloudy. Highs 78-85, coolest South Coast. Dew point 60s. Wind S 5-15 MPH.

WEDNESDAY NIGHT: Mostly cloudy. Patchy fog. Lows 65-72. Dew point 60s. Wind S up to 10 MPH.

THURSDAY: Mostly cloudy. Chance of showers. Highs 75-82. Dew point upper 60s to lower 70s. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 20-24)

Not a high confidence forecast at this time, but thinking that shower threat continues August 20 then diminishes for the August 21-22 weekend as the tropical moisture plume is pushed to the southeast by high pressure. May see an increase in shower chances again toward the end of the period.

DAYS 11-15 (AUGUST 25-29)

High pressure will try to control the weather with mostly dry conditions, but will have to continue to keep an eye on potential tropical activity or remnant tropical moisture to the south.

C-19 Chat Post – August 15 2021

DAYS 1-5 (AUGUST 14-18)

Transition day! We start out in the hot/humid air mass we have been in during the last few days, although a cold front is heading this way and is going to cut across the region from northwest to southeast during the day, exiting via Cape Cod by tonight. This will deliver a cooler/drier air mass to our region, but to get there, we’ll have to go through a shower and thunderstorm threat. It still looks like a fairly low coverage event overall, with under 50% of the region seeing any activity of note, and possibly 25% or less of the region seeing the heaviest shower and thunderstorm activity. Of course, if you happen to be visited by one of these heavier storms, you can see briefly strong and gusty wind, torrential downpours, lightning, and even some small hail. This type of occurrence will be rather isolated though. For many, this change may be marked by clouds, a gusty breeze, and a lighter shower, or even no rain at all. But if you are out and about today, be prepared for a thunderstorm. This threat will decline rather quickly as we get to mid to late afternoon from northwest to southeast, with only the South Coast still seeing the chance of a shower or storm into early tonight. Sunday through Wednesday we will enjoy 4 days with no rainfall threat thanks to an area of high pressure that comes in from Canada, first sits off to the northwest and north of our area, then right over the region, and then slips off to the southeast. This will account for subtle changes during the fair weather stretch. Sunday’s weather will be governed by a light northerly air flow bringing in the driest air, and then the wind turns more easterly Monday with a more maritime feel, an uptick in humidity you won’t really notice because the air will still be refreshingly cool. Once we get to Tuesday and Wednesday, a more southerly air flow will transport higher humidity into the region, though not oppressive, and without the heat to accompany it. There will also be an increase in cloud cover by Wednesday, but still this 4-day stretch will be one of the best of the summer.

TODAY: Mostly sunny early, then variably cloudy with isolated to scattered showers and thunderstorms from late morning through afternoon, favoring southwestern NH and central MA first, then southeastern NH through eastern MA, eastern CT and RI early through mid afternoon, and areas to the southeast mid afternoon on. Isolated locations may see strong storms. Highs 84-91. Dew point near 70 but falling through the 60s from northwest to southeast by the end of the day. Wind SW 5-15 MPH shifting to NW.

TONIGHT: Clouds and a few showers/thunderstorms possible South Coast early, otherwise mostly clear. Lows 61-68. Dew point falling into 50s. Wind NW 5-15 MPH.

SUNDAY: Sunny. Highs 78-85, coolest coast. Dew point upper 50s. Wind N to variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind variable to N under 10 MPH.

MONDAY: Sunny. Highs 76-83, coolest coast. Dew point middle to upper 50s. Wind N to E up to 10 MPH.

MONDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 57-64. Dew point upper 50s. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 78-85, coolest South Coast. Dew point upper 50s to 60. Wind variable up to S 10 MPH with coastal sea breezes.

TUESDAY NIGHT: Partly cloudy. Patchy fog. Lows 61-68. Dew point lower 60s. Wind S up to 10 MPH.

WEDNESDAY: Partly sunny. Highs 78-85, coolest South Coast. Dew point 60s. Wind S 5-15 MPH.

DAYS 6-10 (AUGUST 19-23)

High pressure off the Atlantic Coast helps open the door for some tropical moisture which results in warm and humid weather here with the daily chance of showers and thunderstorms, but also plenty of rain-free time too. We’ll have to watch for a frontal boundary approaching from the west later in the period which may enhance the shower/storm risk somewhat.

DAYS 11-15 (AUGUST 24-28)

This will continue to be the time period we need to keep an eye on tropical activity off the East Coast or remnant moisture coming this way by way of the Southeast / Mid Atlantic States. Again this is far out there in the future and there is no guarantee we end up seeing anything significant. In fact, high pressure that is forecast by guidance at this time to be to our west and north may very well build in and protect the region from unsettled weather. There will be a lot of fine-tuning to do with the late August forecast.

C-19 Chat Post – August 14 2021

DAYS 1-5 (AUGUST 13-17)

One more hot day from the Bermuda High before a cold front puts an end to the hot spell on Saturday – a transition day, then refreshing air by Sunday. First, more of the same today – sunshine, heat, and high humidity, but only the slight chance of a pop up air mass shower or thunderstorm later, although today’s high temperatures on average will likely come in a bit lower than yesterday’s, and the wind field is weak enough that a light sea breeze may develop at the shoreline, taking a few more degrees off the afternoon temperatures compared to yesterday. Similar to yesterday, a line of showers and thunderstorms will probably fire up over New York later, but today’s activity should occur further west and take longer to get into New England. However the remnants of that line may get into the WHW forecast area in the form of a few showers and possibly a thunderstorm sometime overnight (early hours of Saturday). The cold front responsible for that activity will then cross our region during late morning to late afternoon from west to east Saturday, and based on this timing combined with daytime heating, the greatest chance of showers and thunderstorms during the day Saturday will take place earliest (late morning-midday) in southern NH to central MA and eastern CT, then progress through the remainder of MA and RI early to mid afternoon exiting via Cape Cod later in the day. This frontal timing will not allow temperature to exceed 90 in most areas, and although it will start out quite humid, the passage of the front will deliver less humid air in rather rapid fashion as the day goes on. By Saturday night, we’ll have cleared out and much more comfortable air will have arrived, and this will be the case Sunday with lots of sun, mild air, and low humidity as high pressure builds in. This high will then sit over the region early next week with a great stretch of mid August weather.

TODAY: Mostly sunny to partly cloudy. Isolated afternoon showers and thunderstorms possible. Highs 88-95, cooler some coastal areas. Dew point lower 70s. Wind SW up to 10 MPH with light coastal sea breezes possible.

TONIGHT: Variably cloudy. A shower or thunderstorm possible overnight. Lows 70-77. Dew point upper 60s to lower 70s. Wind WSW up to 10 MPH.

SATURDAY: Variably cloudy. Scattered to numerous showers and thunderstorms from northwest to southeast late morning to late afternoon. Highs 82-89. Dew point lower to middle 70s falling into 60s. Wind SW 5-15 MPH shifting to NW.

SATURDAY NIGHT: Mostly clear. Lows 62-69. Dew point falling to upper 50s. Wind NW 5-15 MPH.

SUNDAY: Sunny. Highs 78-85, coolest coast. Dew point upper 50s. Wind N to variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind variable to N under 10 MPH.

MONDAY: Sunny. Highs 76-83, coolest coast. Dew point middle to upper 50s. Wind N to E up to 10 MPH.

MONDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 57-64. Dew point upper 50s. Wind variable under 10 MPH.

TUESDAY: Mostly sunny. Highs 78-85. Dew point upper 50s to 60. Wind variable up to 10 MPH with coastal sea breezes.

DAYS 6-10 (AUGUST 18-22)

High pressure holds with dry and seasonably warm weather for August 18. High pressure shifts offshore with higher humidity and chance of showers by August 19. August 20-22 indications are for a southwesterly flow with a daily opportunity for showers and thunderstorms as a frontal boundary moves into the region from the west. Does not look like an overly wet pattern, however.

DAYS 11-15 (AUGUST 23-27)

Uncertainty for this period pending the movement of a frontal boundary nearby and the potential for some tropical activity near the US East Coast. For now continuing with the idea of fairly humid and seasonably warm weather with the occasional chance for showers and thunderstorms amidst plenty of rain-free time.

C-19 Chat Post – August 13 2021

DAYS 1-5 (AUGUST 12-16)

The Bermuda High will do its thing for 2 more days, through Friday, with heat and humidity being the rule and thunderstorms being the exception. Only a few may wander into the area later this evening that had formed to the west, and as a cold front begins an approach to the region, the same may happen later Friday night, but there is only the slight chance that any isolated storms can pop up during the afternoon heat as, despite the heat and humidity, we don’t have much in the way of any triggers for them. Reminder #1: If you are outside, try to stay out of direct sun and do as much activity as possible before and after the highest sun angles of the day. Reminder #2: Perseid Meteor Shower continues at peak, but some limited visibility due to haze / smoke / and patchy clouds. Still, the best time to try viewing them high in the northeast sky to overhead is midnight to first light Friday morning. The aforementioned cold front will be making its charge across our area during Saturday morning and midday with our best chance of showers and thunderstorms occurring then. Whether any given location sees that activity or not, the heat and humidity will break that day and by Saturday night, Sunday, and on into Monday, much more comfortable air will be here with a high pressure area building into the region from Canada.

TODAY: Partly cloudy. Isolated afternoon thunderstorms possible. Highs 91-98, cooler in some coastal areas especially the South Coast. Dew point lower to middle 70s. Wind SW 5-15 MPH.

TONIGHT: Partly cloudy. Patchy ground fog. Chance of a shower or thunderstorm mainly west and northwest of Boston late evening. Lows 72-79, warmest in urban centers. Dew point lower to middle 70s. Wind SW under 10 MPH.

FRIDAY: Partly cloudy. Isolated afternoon thunderstorms. Highs 90-97, possibly cooler coastal areas. Dew point lower 70s. Wind SW up to 10 MPH with light coastal sea breezes possible.

FRIDAY NIGHT: Variably cloudy. A shower or thunderstorm possible overnight. Lows 70-77. Dew point upper 60s to lower 70s. Wind WSW up to 10 MPH.

SATURDAY: Variably cloudy. Chance of showers and thunderstorms, especially morning and midday. Highs 82-89. Dew point lower to middle 70s falling into 60s. Wind SW 5-15 MPH shifting to NW.

SATURDAY NIGHT: Mostly clear. Lows 62-69. Dew point falling to upper 50s. Wind NW 5-15 MPH.

SUNDAY: Sunny. Highs 78-85, coolest coast. Dew point upper 50s. Wind N to variable up to 10 MPH with coastal sea breezes.

SUNDAY NIGHT: Clear. Patchy ground fog lower elevations. Lows 55-62. Dew point lower to middle 50s. Wind variable to N under 10 MPH.

MONDAY: Sunny. Highs 76-83, coolest coast. Dew point middle to upper 50s. Wind N to E up to 10 MPH.

DAYS 6-10 (AUGUST 17-21)

High pressure should keep the region dry with low to moderate humidity through the middle of the period before humidity starts to increase and the shower threat starts to appear later in the period, pending the movement of moisture to the south and southwest of New England.

DAYS 11-15 (AUGUST 22-26)

High pressure off the US East Coast with a south to southwest flow of more humid air and we’ll have to watch some tropical moisture and a couple disturbances for shower threats.
