Area Forecast Discussion National Weather Service Boston/Norton MA 1001 PM EDT Sun Sep 27 2020

SYNOPSIS.

Weak low pressure area moving up the coast may trigger a few showers tonight and Monday. Increasingly moist southerly flow out ahead of a cold front will bring showers Tuesday. The greatest chance of rain comes with a series of frontal systems Wednesday into Thursday. Temperatures will be near or slightly above normal until the front cools things down by late week.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/.

10 PM Update .

No changes in the latest update forecast remains on track.

745 PM Update .

Made some adjustments increasing the cloud cover based on latest satellite observations. Forecast looked pretty good, but did bump up the temperatures slightly based on the cloudier forecast. Rest of the forecast remains on track.

3 PM Discussion .

Northern stream shortwave digging over the Midwest will become a high-amplitude trough over the Eastern USA early this week. This kicks out current shortwave ridge off to the east and turns the upper flow over us out of the southwest.

A shortwave embedded in the southwest flow will approach New England tonight, supported by a weak jet that passes to our west. This will generate scattered showers over Srn New England overnight. But with limited moisture expect any showers to be light.

With dew points in the mid 60s, expect similar min temperatures.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/.

Monday .

Shortwave continues to move overhead, with clouds and scattered showers. As with tonight, the available moisture will be limited and thus rain amounts will be light. Expect similar max temperatures to today.

Monday night .

The Monday shortwave moves off to the east. Expect mainly rain- free weather. Dew points will still be in the mid 60s

LONG TERM /TUESDAY THROUGH SUNDAY/.

Tuesday-Thursday

High pressure over the Atlantic continues to pump warm moist air into the region with a moderate southerly flow on Tuesday. A weak upper-level vorticity max embedded within the large scale flow will provide sufficient forcing for a few scattered showers on Tuesday afternoon. SPC has the area underneath a general risk for thunderstorms on Tuesday as MLCAPE values are expected to exceed 200 J/kg across most of the forecast region. While bulk shear values are certainly favorable (~ 30 kts), the forcing available doesn't appear to be enough to warrant thunderstorm chances for our area.

Tuesday night begins a 48 hour period of much needed rainfall for southern New England. This 48 hour period will be comprised of 2 separate events. The first event will occur Tuesday night into late Wednesday morning as an upper-level low over Canada and associated cold front lifts northeast over New England. With abundant moisture in place from the persistent moist southerly flow the past few days, confidence is increasing that western MA/CT will see some substantial rainfall (1-2"). Because the lifting cold front will not make it to the eastern zones, forcing over those areas will not be as strong, and thus less rainfall is forecast. Nonetheless, forcing over the eastern zones should be sufficient enough for light- moderate rain showers.

While there is some uncertainty in the timing between these two events, the consensus among the models is that there will be a period of lighter rainfall Wednesday afternoon before event number 2 unfolds. Wednesday night, an upper-level low from the south will move up the east coast and give us our second round of heavy rainfall. This time however, the eastern zones are expected so see more significant rainfall. Showers with this secondary low should continue well into Thursday morning before tapering off Thursday afternoon. When all is said and done, we could see anywhere from 1.5- 3" of new rainfall across portions of the forecast area.

Friday-Sunday

Cooler drier air filters in behind the upper-level low that exits the region Thursday. Another round of showers may be possible Friday night into Saturday, but confidence is low at this time. High pressure and more seasonable temperatures will build into the region for Saturday and Sunday.

AVIATION /02Z MONDAY THROUGH FRIDAY/.

Forecaster Confidence Levels .

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

Tonight . Moderate confidence.

MVFR to IFR ceilings spreading in as low pressure lifts northward from the Mid Atlantic states. On top of this will see rain showers spreading in as well. Cannot rule out LIFR ceilings across the south coast late tonight. Am anticipating visibilities to fall into the MVFR to IFR range as areas of fog develop. Think that PVD/ORH/BDL and BAF have the best chance of getting into LIFR fog.

Monday . Moderate confidence.

MVFR/IFR to start with scattered showers and patchy fog. Should see most areas improving to VFR by late morning or early afternoon. Only exception is across Cape Cod and the Islands where MVFR ceilings are anticipated to linger.

Monday night . Moderate confidence.

VFR conditions initially. Will see areas of MVFR to LIFR in patchy fog after midnight.

KBOS Terminal . High confidence in TAF trends. Moderate confidence in timing.

KBDL Terminal . High confidence in TAF trends. Moderate confidence in timing. Outlook /Tuesday through Friday/ .

Tuesday: Mainly MVFR, with local IFR possible. Chance SHRA.

Tuesday Night: Mainly MVFR, with areas IFR possible. Breezy. SHRA likely.

Wednesday: Mainly MVFR, with local IFR possible. Windy with local gusts up to 30 kt. SHRA likely.

Wednesday Night: Mainly MVFR, with areas VFR possible. Breezy. SHRA.

Thursday: Mainly VFR, with local MVFR possible. Breezy. Chance SHRA.

Thursday Night: VFR. Breezy.

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

MARINE.

A disturbance moving up from the Mid Atlantic coast will bring a chance of showers tonight into Monday. Expect increasing south winds and building seas. Patches of fog may bring vsbys 1 to 3 miles. Small Craft Advisory continues for some of the southern coastal waters due to marginal rough seas. Gusts up to 20 kt.

Scattered showers move off to the east Monday night. Reduced vsbys in patchy fog overnight. South winds less than 20 kt. Seas up to 5 feet on the exposed southern waters, less than 5 feet on all other waters.

Outlook /Tuesday through Friday/ .

Tuesday: Winds less than 25 kt. Seas up to 5 ft. Slight chance of rain showers.

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

Wednesday: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 8 ft. Rain showers.

Wednesday Night: Low risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 9 ft. Rain showers.

Thursday: Low risk for Small Craft Advisory winds with local gusts up to 30 kt. Rough seas up to 10 ft. Chance of rain showers.

Thursday Night: Winds less than 25 kt. Areas of rough seas.

Friday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
