Area Forecast Discussion National Weather Service Boston/Norton MA 754 PM EDT Fri Sep 25 2020

SYNOPSIS. Outside of a brief and isolated sprinkle the forecast remains dry through the overnight hours. Morning fog/drizzle develops along the southcoast through the Cape/Island, but will dissipate before the afternoon. 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 that front cools things down.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. 750 PM update .

Low cloudiness and fog has already developed over portions of Cape Cod, Martha's Vineyard, Nantucket and southern Bristol County, MA as of 750 PM this evening. Short-range models are now more bullish on low cloud development during the overnight hours across a large portion of southern New England. Have increased sky cover after midnight and added low clouds to the aviation grids, especially in northern CT, RI, and central MA. Dewpoints are forecast to remain in the upper 50s in those areas and with temperatures cooling rapidly this evening, expect patchy fog, locally dense, to develop, mainly south of the Mass Pike.

Previous discussion .

After an afternoon of summer-ish conditions temperatures will dip back into the 60s after sunset. BOX radar has seen a few isolated showers develop as result of clouds bubbling up from daytime heating across western Massachusetts/Connecticut. Remaining diurnal clouds will dissipate, but low stratus and coastal fog/drizzle forms. Areas along the immediate south coast of Rhode Island, southcoast of Massachusetts, and the Cape/Islands have the potential for areas of dense fog through 10 AM. Overnight wind conditions become light and out of the southwest. Temperatures fall to the mid-50s inland and to low-60s at the coast.

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/. Morning fog/stratus will burn off during the late morning hours. Mixture of sunshine and clouds will follow for the day, though, along Route 2 and north into southern New Hampshire/Vermont expect mainly sunny conditions. Thicker coastal clouds will keep the shoreline cooler in the low-70s. A blustery 925mb southwest wind at 20 knots will keep an off shore wind for eastern Massachusetts, meaning a sea breeze isn't expected for areas on the North Shore/South Shore. Saturday night into Sunday morning is a near repeat of the Friday night into Saturday morning forecast.

LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/. Highlights .

* Warmer than normal Sunday through Tuesday

* 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 .

Sunday .

Despite moisture at low levels, mid levels are dry, with GFS showing K Indices in the teens. So, the day should be mainly dry. The exception, though, will be in a portion of southern RI as well as Cape Cod and the Islands, where we have a slight chance of a shower, due to closer proxmity to weak low pressure off the mid-Atlantic coast. With southerly flow, it will become warmer and more humid. Highs will reach 75 to 80 and dewpoints are forecast to rise to the mid and upper 60s, with near 70 along the south coast by evening.

Sunday night through Monday night .

A weak warm front is forecast to move across the area from south to north Sunday night into Monday afternoon. This could trigger scattered showers. While not in the grids at this time, cannot rule out a stray thunderstorm on Monday. Models are not forecasting more than 0.25 to 0.33 inches of rain in any one area, so not any drought relief from this system. Despite cloud cover, looking for highs to again reach the mid to upper 70s, since lows Sunday night will have remained in the 60s.

Tuesday into Wednesday .

Models are finally converging on timing of a slowly advancing cold front. It looks like it will move into western sections Tuesday night and exit the region Wednesday afternoon. The dynamics with this system are quite strong, with an upper level jet on the order of 140 knots. Expecting showers to be more widespread. There is a also the chance for scattered thunderstorms, especially in western and central MA and northern CT. Locally heavy downpours are possible and a few storms could produce gusty winds. There remains significant discrepancies with potential rainfall amounts . with some models prolific just west of our forecast area and others not so. We are forecasting one-quarter to one-half inch, except the potential for closer to three-quarters to one inch in the slopes of the Berkshires. The majority of showers should be off the coast by late Wednesday afternoon. Highs should be 75 to 80 Tuesday but a more seasonable 70 to 75 Thursday.

Late Wednesday night and Thursday .

Behind the front cooler air filters in and will bring temperatures closer to their seasonable normals. While the GFS remains dry, the ECMWF continues to lift a strong upper low northeastward from the southeastern U.S. with a corresponding deep low pressure system at the surface heading our way, which would mean a stormy Thursday. We have chosen a blend, with partly cloudy skies and a chance of showers, until we have a chance to see how the situation evolves.

Friday .

Sunny skies and much drier dewpoints as weak high pressure settles in. Highs in the upper 60s to around 70.

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

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

2350Z update .

Tonight . Moderate confidence.

VFR to start, except IFR ceilings/fog over Cape Cod and the islands. After 05Z, expect development of MVFR/local IFR across much of northern CT, RI, and interior MA, mainly south of the Mass Pike. IFR becomes LIFR ceilings and vsbys Cape Cod and the islands. Patchy fog also inland, especially in river valleys. Areas of drizzle possible from RI eastward and southeastward to Cape Cod and the islands.

Saturday . High confidence.

MVFR/IFR inland becoming VFR around 13Z. IFR/LIFR over Cape Cod/Islands, becoming VFR by 15-17Z. SW winds increasing to around 10 kts should preclude east coastal MA sea breezes.

Saturday Night . Moderate confidence

Increasing clouds, VFR to start for most of the area, then CIGs falling to MVFR/IFR across the interior. Patchy MVFR fog.

KBOS Terminal . High confidence in TAF. Sea breeze remains in place until sunset, SW flow returns tonight and should increase to around 10 kts Saturday, precluding sea breeze development.

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

Saturday Night: Mainly VFR, with areas MVFR possible. Slight chance SHRA, patchy BR.

Sunday: VFR.

Sunday Night: Mainly MVFR, with areas IFR possible. Slight chance SHRA.

Monday: Mainly MVFR, with areas VFR possible. Chance SHRA.

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

Tuesday: Mainly MVFR, with areas VFR possible. Breezy. Chance SHRA, slight chance TSRA.

Tuesday Night: Mainly MVFR, with local VFR possible. Breezy. Chance SHRA, chance TSRA.

Wednesday: Mainly MVFR, with areas VFR possible. Windy with local gusts up to 30 kt. Chance SHRA.

MARINE. 750 PM update .

Light winds and calm seas overnight and into Saturday morning. The pre-dawn hours will bring in low stratus, areas of dense fog, and drizzle - expect low visibility through 10am and noon.

Outlook /Saturday Night through Wednesday/ .

Saturday Night: Winds less than 25 kt. Slight chance of rain showers, patchy fog.

Sunday: Winds less than 25 kt. Seas locally approaching 5 ft.

Sunday Night through Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers.

Tuesday Night: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Areas of rough seas. Chance of rain showers.

Wednesday: Moderate risk for Small Craft Advisory winds with local gusts up to 30 kt. Rough seas up to 11 ft. Chance of rain showers.
