SYNOPSIS
High pressure provides quiet weather pattern through Friday morning. Then a quick shot of light rain late Friday into very early Saturday morning. An active weather pattern late Saturday into early next week, but lots of uncertainty on how things evolve at this point. Temperatures trending near to below normal as we head into the middle of the week.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/
Highlights:
* Dry and slightly more mild night ahead, under mostly clear skies.
The final afternoon of November comes to a close under an abundant amount of sunshine and temperatures well into the 40s. Continued quiet conditions overnight with high pressure centered south of the region, closest to the Island of Bermuda. Southwest flow advects a warmer airmass overnight, low temperatures are noticeably warmer in the upper-20s to middle-30s. Where the overnight lows are the highest is along the coast, Cape Cod and Islands where the low will hover around 40 degrees. These temperatures are about 10 to 12 degrees warmer than the night before! And roughly 5 degrees warmer than the normal low for late November/early December.
WAA allows for some added high clouds tonight, but otherwise a dry and mostly clear night ahead with light southwest winds 5 to 10 mph.
An occasional stronger gust is not totally out of the question do to a strong LLJ of 35 to 40 knots only a thousand to two thousand feet above the surface. Forecast soundings are pretty inverted above the surface, which will keep majority of the wind from mixing to the ground.
SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/
Highlights:
* Dry, increasing clouds Friday morning through the early afternoon.
* Rain arrives Friday afternoon into the evening, then comes to an end after midnight from west to east.
After a sunny start, clouds are increasing from west to east with the arrival of a more moist airmass. Deep southwest flow will keep temperatures seasonably comfortable for this first day of December.
Afternoon highs largely in the upper-40s and lower-50s.
During the afternoon the mid-level shortwave rides along the top to the mid-level ridge, which provides lift for the light rain showers.
The best forcing appears to be south of Block Island to Nantucket due to a strong LLJ. And because of the strong WAA this will remain all rain event. Rainfall is expected to be on the lighter side, QPF around 0.1 to 0.2 inch. There is some guidance that suggest there could be a dry slot over southeast MA early on, which could delay the onset. As for the timing, high-res models are in good agreement with a starting around 2pm to 4pm for the I-91 corridor and then reaching the I-95 corridor between 4pm and 6pm. The system is fairly progressive, exiting southern New England, from west to east, between midnight and 4am.
Another mild night ahead with lows in the middle-30s to lower-40s under mainly cloudy skies. Winds are light from the south/southwest.
LONG TERM /SATURDAY THROUGH THURSDAY/
Highlights
* Quick shot of light rain late Fri into early Sat.
* Active pattern late Sat through early next week. Mostly weak/progressive systems, but could see a stronger system early next week. Details still uncertain at this point. Temperatures trending near to below normal.
Latest guidance suite continued to show issues with the timing and amplitude evolution of a broad mid level trough traversing the CONUS next week. Continue to have below average confidence in the details beyond Monday. That said, some broader ideas in the guidance suite do seem to be coming though with greater confidence.
Near to slightly above normal temperatures this weekend expected to quickly transition to below normal by the middle of next week.
The precipitation aspect will be the tougher nut to crack. Weak high pressure should be over southern New England Saturday, so thinking this will most likely be the dry day this weekend. A low pressure passing by to our south should provide a risk for some rainfall sometime Saturday night into Sunday. A second low pressure traversing the cold front of this system should then extend the risk of rainfall into Monday. The timing of all this is not well defined.
Thus, kept rainfall chances broad.
Beyond Monday, thinking most of our region should remain dry, with the possible exception of some ocean-effect showers near the east coast of MA. A subtle shift in wind direction could result in either a lower risk by driving these potential showers offshore with a more NW wind, or increase the risk with more of a N to NE wind. Just don't have enough confidence to deviate much from the ensemble-based solutions just yet.
AVIATION /00Z FRIDAY THROUGH TUESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Tonight...High confidence.
VFR with SW winds around 5-10 kts. Still 10-15 kts across the Cape/Islands. Will have a SW low level jet of 30-40+ kts sliding through. Given the boundary layer decouples have added LLWS mention to all terminals away from the south coast. Timing wise looking most likely between roughly 03-09Z.
Friday...High confidence.
Dry weather and VFR to begin the day, but by days end, light rain overspreads much of the region from west to east with VFR cloud bases, but MVFR across western MA. Light rain arriving across western zones after 20z. SW winds 10-15 kt, gusting up to 20 kt possible Cape Cod and the Islands.
Friday Night...Moderate confidence.
VFR/MVFR to start the night, lowering to MVFR/IFR after midnight with periodic light rain. S/SW wind less than 10 kts.
KBOS Terminal...High confidence in TAF.
VFR with dry weather and SW winds at 5-10 kts. Strong SW jet slides through tonight, so will have LLWS concerns from roughly 03-09Z. Light rain possible after 22z Friday.
KBDL Terminal...High confidence in TAF.
VFR with dry weather and SW winds at 5-10 kts. Strong SW jet slides through tonight, so will have LLWS concerns from 02-08Z.
Light rain possible after 20z Friday.
Outlook /Saturday through Tuesday/...
Friday Night: MVFR/IFR conditions possible. Chance RA, patchy BR.
Saturday: Mainly VFR, with local IFR possible.
Saturday Night: Mainly VFR, with areas IFR possible. Chance RA.
Sunday: MVFR/IFR conditions possible. Chance RA.
Sunday Night: MVFR/IFR conditions possible. Breezy. RA likely.

Friday...high Confidence.
Dry weather to begin the day, but light rain overspreads all waters by late afternoon. SW winds 10-15 kt, gusting up to 20 kt at times. Seas are 3 to 5 feet, but diminishing during the second half of the afternoon.
Friday Night...High confidence.
Light rain ending, exiting east of the waters before sunrise.
