SYNOPSIS. High pressure builds in this evening, allowing for a chilly night tonight followed by mostly sunny and seasonable conditions on Tuesday. Winds increase from the south out ahead of a strong cold front that crosses Southern New England late Wednesday into overnight, with the potential for brief downpours and strong to perhaps damaging winds. Gusty conditions continue on Thursday along with cooler temperatures. A low pressure system brings our next chance for precipitation on Saturday but the overall weather pattern features quiet and seasonable conditions.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/.

4 PM Update .

Visible satellite shows decreasing clouds across the region. This will set up a Cold night in the 20s for most locations away from the immediate coast with clear skies and winds decoupling. 30s for Cape and the Islands and coastal locations. With winds turning north over the Cape and Islands, there will be ocean- effect clouds and perhaps a spot shower over the Outer Cape with -2C air mass at 925mb being advected over SSTs in the upper 40s to low 50s across Gulf of Maine. Any showers that do materialize will be in the form of rain given the thermal profile. Winds become lighter towards daybreak for coastal locations.

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

Tuesday .

High pressure in control will lead to mostly clear skies. Winds will gradually shift to southeast and eventually south as high pressure moves offshore. With 925mb temps 0 to -3C, expect pretty seasonable high temperature readings in the mid to upper 40s. Mix of sun and clouds, perhaps staying mostly cloudy across Cape locations and even eastern MA coast due to ocean effect cloud cover. Overall light winds across the region so overall a very decent day for late November standards.

Tuesday night .

As high pressure moves offshore, a very dynamic low pressure system will be moving eastward from the Great Lakes and the Mississippi River valley. This will support a tightening pressure gradient and increasing flow out of the south. This strong southerly flow will advect a warmer and more moist air mass over southern New England. Overnight lows are tricky given that temps will likely fall into the mid 20s to low 30s in the typically cold interior spots. But then during the latter half of the overnight hours, as 925mb low level jet increases to 25 to 30 kt, this will help to moisten the lower levels with 925-850mb RH fields rising to between 50 and 75 percent after midnight. Some mesoscale guidance are hinting at the potential for some light wintry mix across the interior higher elevation where it stays cold enough and where there is just enough moisture in the boundary layer but no good snow growth aloft. Either way, any wintry precipitation will be light and rather transient as warmer air continues to move in towards daybreak.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Highlights

* Mild temperatures Wednesday with showers developing ahead of a strong cold front Wednesday afternoon.

* Strong cold front pushes through the region with moderate rainfall and potentially damaging wind gusts Wednesday night.

* Cold and blustery Thursday afternoon with strong post frontal wind gusts.

Wednesday and Thursday

An active weather pattern during the extended forecast will begin on Wednesday with southern New England being caught between high pressure off the East Coast and a deep low pressure system centered roughly over Lake Superior. This will support a tightening pressure gradient and increasing flow out of the south. This strong southerly flow will advect a warm/moist air mass over southern New England. As a result most of the region will experience mild/cloudy conditions during the first half of Wednesday. As Wednesday progresses, PWATs climb to near 1 inch and saturate the column enough so that low- level WAA will supply sufficient forcing for showers to develop ahead of a strong cold front. As this front moves through the region Wednesday night, winds and rainfall will intensify. Latest model guidance resolves a robust low-level jet with winds as high as 80 knots at 925 hPa over some portions of the forecast area. Wind headlines are becoming increasingly likely for this time period. This will be a fast moving front, thus the heavy rainfall should be out of the region after midnight Wednesday night/Thursday.

After the front exits east of the region, southern New England will be left beneath a -30 Celsius 500 hPa cold pool. This will support strong WNW post-frontal winds on Thursday afternoon as steep lapse rates will allowing mixing to 850 hPa where winds may be as high as 50 knots. Thus, wind headlines may be needed for Thursday afternoon as well. Winds will gradually come down Thursday evening as the atmosphere decouples.

Friday through Sunday

A little bit of deja vu for the Friday to Sunday time frame. High pressure builds in behind the cold front on Friday supporting dry weather and slightly below normal temperatures. This will be followed by another potentially strong cold front pushing through the region on Saturday with potentially strong winds and heavy rainfall. High pressure builds in behind this cold front to support a quiet end to next weekend.

AVIATION /21Z MONDAY THROUGH SATURDAY/. Forecaster Confidence Levels:

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

15Z TAF Update:

Through 00z: High confidence.

VFR cigs. NW winds 5-10 kt with gusts 15-20 kt across eastern MA and Cape terminals.

Tonight: High confidence.

Mostly VFR cigs, but potential for a period of MVFR cigs due to 2000 ft stratocu across Cape/Island terminals after 04z. NW to N winds 5-10 kt for most terminals, lighter across the interior than near the coast.

Tuesday: High confidence.

Generally VFR but there is potential for offshore stratocu to return back landward toward PVD/BOS/possibly BED as winds become light SE/S after 17z.

Tuesday night: Moderate confidence.

Starting VFR but deteriorating to widespread MVFR and localized IFR after 05z. Light SE winds turning S gusting to 15-20 kt near the coast towards daybreak. Low probability of some light wintry mix across interior higher elevation after 06z.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF.

Outlook /Wednesday through Saturday/ .

Wednesday: Mainly MVFR, with local IFR possible. Strong winds with gusts up to 40 kt. RA, slight chance FZRA.

Wednesday Night: Mainly VFR, with local IFR possible. Strong winds with gusts up to 45 kt. RA.

Thursday: VFR. Strong winds with local gusts up to 40 kt.

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

Friday: VFR. Breezy.

Friday Night: VFR. Breezy. Slight chance RA, slight chance FZRA.

Saturday: Mainly VFR, with local MVFR possible. Windy with local gusts up to 30 kt. Chance RA.

MARINE. Forecaster Confidence Levels:

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

Overall high confidence. Gale Watches issued for late Wednesday into Thursday evening.

NW winds diminish overnight tonight to below SCA thresholds but wave heights stay above 5 ft across the southeastern outer waters through Tuesday morning. High pressure builds in across the waters, leading to quiet boating weather for Tuesday into Wednesday morning. Winds increase from the south on Wednesday reaching 35-40 kt with potential for even higher gusts along with rough seas. Therefore, Gale Watches have been hoisted for late Wednesday into Thursday evening for all waters.

Outlook /Wednesday through Saturday/ .

Wednesday: Low risk for gale force winds with gusts up to 35 kt. Areas of rough seas. Rain.

Wednesday Night: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 10 ft. Chance of rain. Local visibility 1 to 3 nm.

Thursday: Strong winds with gusts up to 30 kt. Rough seas up to 9 ft.

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

Friday through Friday Night: Winds less than 25 kt. Seas locally approaching 5 ft.

Saturday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft. Chance of rain.

BOX WATCHES/WARNINGS/ADVISORIES. CT . None. MA . None. RI . None. MARINE . Small Craft Advisory until 1 AM EST Tuesday for ANZ230>237-251. Gale Watch from Wednesday afternoon through Thursday evening for ANZ230>237-250-251-254>256. Small Craft Advisory until 7 AM EST Tuesday for ANZ250-254>256.
