Area Forecast Discussion National Weather Service Boston/Norton MA 650 PM EST Tue Mar 2 2021

SYNOPSIS. An extended period of dry weather is expected through early next week. After a brief moderation in temperatures Wednesday, cold/blustery weather will return Thursday and continue into the weekend although not to the magnitude of what occurred today. A significant moderation in temperatures is anticipated early next week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. 650 PM update .

Clear skies across SNE this evening, but some mid/high clouds will overspread the region later tonight ahead of mid level shortwave moving SE into northern New Eng. Winds continue to diminish but will remain gusty over the outer Cape/Islands through the night. Forecast on track.

Previous discussion .

Strong low pressure over the Canadian Maritimes will continue to move further northeast tonight. This coupled with the loss of diurnal heating will allow the windy conditions to subside this evening. Things have already dropped below wind advisory criteria, so we allowed the wind advisory to expire on time.

Otherwise, the very progressive pattern will allow significant warm advection to occur aloft tonight. While that will not be initially realized at the surface, low temps will be held in the teens to the lower 20s with much less wind than last night. Some mid/high level cloudiness will overspread the region in response to the warm advection aloft, but it will remain dry.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. * Much milder Wednesday with considerably less wind than today

Wednesday .

What a difference 24 hours can make sometimes especially in early March. The progressive pattern will allow 925T to moderate to near 0C by late Wednesday afternoon. This coupled with westerly flow will allow afternoon highs to recover well into the 40s to perhaps near 50 across RI/SE MA. There will be a bit of a breeze with some westerly gusts between 20 and 25 mph, but certainly nothing like today. That coupled with temperatures around 20 degrees milder will make quite a difference for outdoor activities by Wednesday afternoon.

Wednesday night .

Another cold front will cross the region Wednesday night, but the magnitude of the cold air will be nothing like today. Other than perhaps a brief flurry or two in the Berks, dry weather will prevail given the lack of moisture/forcing. Low temps by daybreak Thursday will mainly be in the 20s.

LONG TERM /THURSDAY THROUGH TUESDAY/. Highlights

* Below average temperatures move in for late week and into the weekend. Average high temperatures are in the low 40s for this time of year in our major metropolitan areas.

* Little to no chance of precipitation over the long term forecast period.

* Model consensus that a warm up is on the way early next week, but the exact timing is still up in the air.

Thursday Night and Friday .

A more seasonable Thursday, with highs in the low 40s south and east and upper 30s north and west, before a cold front slides through the region. Any precipitable water present in the column, already on the order of hundredths, will be met by extremely low dewpoints, in the single digits, making the possibility of precipitation extremely low.

925mb winds Thursday evening suggest there is a possibility for gusty winds to return to the region, especially across the maritimes, the high elevations of the Worcester hills and the downslope of the Berkshires. CONSAll guidance was blended into the NBM data to enhance the wind potential across the maritimes.

On Friday, temperatures take a dive back into the 30s. Low temperatures on both Thursday and Friday night will bottom out in the 10s north and west to the mid 20s south and east across the Cape and Islands.

Saturday and Sunday .

Sunny skies will prevail for the weekend, and temperatures will remain below average, topping out in the 30s, slightly warmer on Sunday compared to Saturday. Widespread 10s north and west and 20s south and east for lows. Light W/NW winds except across the maritimes where stronger gusts are likely on Saturday.

Early next week .

Guidance suggests that we return to seasonable temperatures on Monday, with highs in upper 30s to low 40s across the area. Beyond Monday, there is a strong signal that both the NAO and AO teleconnections will trend positive. Given that the end of the forecast period is still five days away, there is good model consensus that the region will warm to the mid to upper 50s starting next Tuesday.

The next shot for considerable precipitation is after our forecast period ends.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. Forecaster Confidence Levels.

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

00z Update .

Tonight through Wednesday night . High Confidence in VFR conditions. Gusty NW winds will continue to diminish this evening with winds shifting to the SW after midnight. Westerly wind gusts during the day Wednesday will be on the order of 20 knots.

KBOS TAF . High confidence. VFR.

KBDL TAF . High confidence. VFR.

Outlook /Thursday through Sunday/ .

VFR. Breezy.

MARINE. Tonight through Thursday night . High Confidence.

We have replaced Storm Warnings with Gale Warnings as low pressure over the Maritimes continues to lift further northeast. Wind gusts will finally drop below Gale thresholds after midnight. Westerly wind gusts of 20 to 30 knots are anticipated on Wednesday with the strongest of the winds across the southern waters. Winds shift to the NW Wed night behind another cold front. Small craft headlines will be needed Wed into Wed night for many waters once the Gale Headlines expire this evening.

Outlook /Thursday through Sunday/ .

Wednesday Night: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of seas approaching 5 ft.

Thursday: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Local rough seas.

Thursday Night: Moderate risk for Small Craft Advisory winds with local gusts up to 30 kt. Areas of rough seas. Chance of freezing spray.

Friday through Friday Night: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of freezing spray.

Saturday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft.
