Area Forecast Discussion National Weather Service Boston/Norton MA 640 PM EST Wed Mar 3 2021

SYNOPSIS. An extended period of dry weather will continue into the middle of next week. A cold front will bring the return of blustery and chillier temperatures Thursday and unseasonably cold weather Friday through the weekend. A pattern change toward above normal, early springlike temperatures then takes hold of our region's weather into a good part of the upcoming workweek. Dry weather continues into next week.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/. 630 PM Update:

Satellite imagery early this evening shows a considerable shield of scattered to overcast cloudiness across the northern two-thirds of Southern New England, clouds which continue to expand slightly southward as the boundary layer continues to stabilize. Appears to be doing so ahead of an approaching shortwave disturbance seen on water vapor imagery near NW PA and into western NY, a feature which should pass quickly into our southern waters thru overnight. The clouds are not being handled well at all across most available guidance sources. Recent RAP/HRRR guidance is handling these clouds relatively speaking the best with a layer of high RH between 900-800 mb, but it brings these in after 04z, so not quite meshing with current conditions/trends.

So for this update I ended up increasing cloudiness through the early-overnight as it appears mostly cloudy skies may linger for some time. How long these clouds hang on will have implications on the temperature forecast. Brought hourly temperatures up by few degrees as well through the early-overnight hrs, but adjustments to lows and hourly temps could be needed if the clouds continue thru the balance of the overnight.

No changes to lows at this time, in the 20s to near freezing, as colder air filters in late in the overnight. The ongoing cloudiness does add a level of uncertainty to the low temperature forecast, and upward adjustments to these could be warranted in later updates.

Previous discussion:

Scattered diurnal CU will dissipate early this evening with the loss of daytime heating. A cold front will cross the region late tonight. Very little moisture/forcing associated with the front, so it will come through dry other than perhaps a few flurries in the Berkshires. Low temperatures by daybreak will be in the 20s to near 30.

SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/. * Blustery and chillier temperatures return Thursday * Very cold with wind chills in the single digits late Thu night

Thursday .

Blustery/chillier weather will be ushered back into the region on Thursday behind the cold front. While the magnitude of the wind/cold will be nothing compared to what we experienced on Tuesday; it will be a change from today. Sunny skies and steep lapse rates will promote excellent mixing in the cold air advection pattern. This should result in northwest wind gusts of 25 to 35 mph developing by afternoon. High temperatures will range from the middle 30s in the higher terrain; to the upper 30s and lower 40s in the lower elevations. It will feel colder though with the wind.

Thursday night .

A strong shortwave/reinforcing cold front will move through the region Thursday night. Again, moisture is lacking so will continue with a dry forecast. That being said, it will deliver a reinforcing shot of rather cold air for early March. Low temperatures will be in the teens to near 20 and it will remain quite breezy overnight. This will drop wind chills into the single digits and even a bit below zero in the high terrain by daybreak on Friday.

LONG TERM /FRIDAY THROUGH WEDNESDAY/. Highlights .

* Below average temperatures Fri thru Sunday with mainly dry weather.

* Pattern change toward above normal temperatures, starting Monday but especially Tues and Wed. 50s to even near 60 possible by Wed away from Cape Cod.

* Dry weather prevails through midweek.

Details:

Friday through Sunday:

Cyclonic flow aloft/longwave troughing to remain established across Southern New England through the period, associated with a retrograding upper-level low from the Canadian Maritimes.

Though the forecast calls for dry weather, it will feature a period of below-normal temperatures as the trough ushers in colder temps. Friday looks to be the coldest in the stretch with the coldest low- level temps over the region (850mb temps -12 to -15C), and NW winds will allow for mid teens to low 20s daytime wind chills. Still some modest breezes into Sunday as well, but temperatures slowly modify each day.

Highs Fri in the upper 20s to lower 30s, only a degree or two warmer on Sat. By Sunday, highs should range in the low to mid 30s, with upper 20s across the higher terrain. Lows in the teens to mid 20s through the period.

Monday thru Midweek:

Monday is a transition period with a significant pattern change toward above-normal temperatures starting Tues into potentially a good part of the upcoming workweek. By midweek, temperatures should be well into the 50s for most away from Cape Cod. Given the long stretch of dry weather that may bias temperatures warmer with soils drying, a few 60s could be in reach by Wed as well.

Large deep-layer high pressure over the mid-Atlantic region shifts eastward off the coast and generally remains in place through midweek. This will bring mostly clear conditions, SW breezes and steadily warming low-level temps to the region. For Monday, highs should trend near to slightly above normal in the upper 30s to low- mid 40s. By Tues and Wed, warmup begins with highs Tues in the mid 40s to mid 50s. By Wed most are in the 50s except mid 40s across Cape Cod with the cooler water temps. The only fly in the ointment is potential for sea-breezes but at this time range it's tough to depict that mesoscale detail.

When the next chance of precipitation affects Southern New England remains an open question. There's high confidence that dry weather will continue until midweek, whereas the GFS and ECMWF start to differ on the approach of a cold front late in the upcoming week. That may be our next best chance for precip but it's far from a sure thing at this point.

AVIATION /00Z THURSDAY THROUGH MONDAY/. Forecaster Confidence Levels.

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

00z TAF Update:

Tonight: High confidence.

VFR. SCT-OVC ceilings with bases 050-060 should linger into the overnight, less cloudiness across Cape Cod/ACK. NW winds 5-10 kt, becoming 5-8 kt late.

Thursday and Thursday night . High confidence. VFR with NW wind gusts of 20 to 30 knots developing by Thu afternoon and persisting into Thu night.

KBOS TAF . High confidence in TAF. VFR.

KBDL TAF . High confidence in TAF. VFR.

Outlook /Friday through Monday/ .

Thursday Night: VFR. Windy with gusts up to 35 kt.

Friday: VFR. Windy with areas of gusts up to 35 kt.

Friday Night: VFR. Windy with local gusts up to 35 kt.

Saturday through Saturday Night: VFR. Breezy.

Sunday: VFR.

MARINE. Tonight . High Confidence. Fairly quiet on the waters this evening, but we will see small craft NW wind gusts will develop late tonight in the northern waters behind a cold front.

Thursday and Thursday night . High Confidence. Strong cold advection will yield good mixing over the waters, which will result in NW wind gusts of 25 to 35 knots Thu and Thu night. Small craft headlines have been issued for all waters, but we did go with Gale Watches late Thu into Thu night when the strongest wind gusts are anticipated. Widespread light freezing spray is also anticipated Thursday night.

Outlook /Friday through Monday/ .

Friday through Friday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas.

Saturday: Winds less than 25 kt. Seas up to 5 ft.

Saturday Night: Winds less than 25 kt. Areas of seas approaching 5 ft.

Sunday: Winds less than 25 kt.

BOX WATCHES/WARNINGS/ADVISORIES. CT . None. MA . None. RI . None. MARINE . Small Craft Advisory from 9 AM Thursday to 7 AM EST Friday for ANZ230>237.
