Area Forecast Discussion National Weather Service Boston/Norton MA 708 AM EDT Fri Sep 25 2020

SYNOPSIS. Dry weather will continue, although there is a very slight chance of showers during the afternoon hours this weekend. Early next week will feature increasingly moist southerly flow out ahead of a cold front, which arrives around Wednesday. There will be chances of showers each day, but greatest with the front itself. Temperatures will be near or a little above normal until this front cools things down.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

7 am update .

No significant changes to the forecast this morning. Temperatures have been a bit slow to warm in interior MA/CT so brought those in line with observations. Very low dewpoint depressions this morning with temperatures ranging from the upper 40s to low 60s. This with very light winds has allowed some patchy fog to develop, mainly over the Cape and islands, but should dissipate in the next few hours.

Previous Discussion .

High pressure remains in control of our weather. High level clouds should be shunted a little farther north, although we could see another round of smoke aloft, leading to some hazy sunshine. Mainly light SW winds across the interior today, with seabreezes developing along the east coast of MA towards late morning. Above normal temperatures continue.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. High pressure near Bermuda will remain the dominant feature into Saturday. The increasing south flow will bring more humidity into southern New England. Most likely this will only mean more clouds, although cannot dismiss the possibility for a few showers or sprinkles Saturday afternoon. While many areas could really use the rainfall, not seeing this as an opportunity to get more than a few hundredths, where it rains at all. The only forcing is a weak mid level shortwave, and one which should be mainly passing by to our south. More lower clouds should arrive, especially along and south of the Mass Pike. Above normal temperatures continue.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Highlights .

* Warmer than average; warmest on Sunday and becoming more seasonable mid week

* Moist, southerly flow with the return of scattered showers Sunday night and Monday.

* A cold front brings more widespread rain chances around Tuesday or Wednesday along with more seasonable temperatures

Details .

Saturday night and Sunday .

Not too excited about rain chances on Sunday even though some of the guidance wants to keep scattered showers around. High pressure remains anchored offshore while heights will actually be rising behind Saturday's disturbance to our south. Though continued southerly flow ahead of the incoming trough will bring increasingly moist air (dewpoints into the mid 60s), subsidence and lack of a forcing mechanism should keep rain from materializing during the day. Increasing moisture below 850 mb will mean a mix of clouds and sun, with highs approaching 80 F in the warmest spots like the Merrimack and Connecticut River valleys.

Sunday night through Monday night .

A showery pattern sets up late Sunday into Monday night. An upper level disturbance lifts into the mid Atlantic Sunday night and passes over southern New England on Monday; with it comes a 25-35 kt low level jet. A vort max together with the favorable jet dynamics and PWATs >1.5 inches will bring scattered showers to the region; have continued a slight chance for some isolated thunderstorms as well given several hundred J/kg of CAPE and 30-35 kts of 0-6 km bulk shear.

Tuesday through Thursday .

Potential for more widespread and heavier rain comes around Tuesday or Wednesday, but uncertainty in timing and details is high at this point. Guidance has for a long while been advertising a very amplified pattern going into mid week with a strong western ridge and deep eastern trough. Looking at the trend in guidance from the GFS over the last several cycles it shows a westward trend in the trough on Tuesday (i.e. slower to eject). Thus, the approaching cold front has slowed a bit, looking more like a Wednesday passage than late Tuesday. For now will stick with a blend of guidance and increasing POPs Tuesday night into Wednesday. Behind the front cooler air filters in and will bring temperatures closer to their seasonable normals. Beyond Wednesday the ECMWF continues to develop a low over the southern U.S. that lifts through and keeps rain in the forecast late week, at odds with the GFS. This update has added just a slight chance of showers Thursday to account for this.

AVIATION /11Z FRIDAY THROUGH TUESDAY/. Forecaster Confidence Levels .

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

12Z update .

High confidence through Saturday.

VFR. Light southwest winds continue into Friday. With a weak pressure gradient, expect development of sea breezes across eastern MA during the late morning and early afternoon. Light south winds redevelop tonight, and continue into Saturday. mainly dry weather through Saturday, although there is a very slight chance for some showers across the western half of southern New England Saturday afternoon.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF. Outlook /Saturday Night through Tuesday/ .

Saturday Night through Sunday: Mainly VFR, with local MVFR possible.

Sunday Night: Mainly VFR, with areas IFR possible. Chance SHRA.

Monday: Mainly VFR, with local IFR possible. Breezy. Chance SHRA, isolated TSRA.

Monday Night: Mainly VFR, with local IFR possible. Chance SHRA.

Tuesday: Mainly VFR, with local IFR possible. Breezy. Chance SHRA.

MARINE. Relatively light winds and seas are expected through Saturday. Seabreezes expected along the east coast of MA from late morning into this afternoon.

Outlook /Saturday Night through Tuesday/ .

Saturday Night through Sunday: Winds less than 25 kt.

Sunday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers.

Monday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers, isolated thunderstorms.

Monday Night through Tuesday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
