A warm front brings a period of steady rain into tonight, followed by mild temperatures Wednesday into Wednesday night. Low pressure passing well to the north swings a strong cold front through our region late Wednesday night. Colder and windier conditions follow behind this front Thursday through Saturday. Milder temperatures Sunday, before another frontal boundary approaches from the west early next week.

* Increasing temperatures overnight with widespread showers
Thinking the overall trend of the forecast remained on track. The main change this evening was to slow the eastward progress of the rain shield by 1-2 hours. Also brought temperatures back in line with observed trends.
Previous Discussion...
A surface warm front will lift through southern New England tonight with widespread steady/light rain. Low temperatures will likely bottom out in the mid to upper 40s around midnight before temperatures begin to increase in response to the warmer air pass advecting in from the south. Dewpoints increase as well to the low- mid 50s which will also help support the warming temperatures overnight. Could see some patchy fog develop, but surface winds should be strong enough to suppress any widespread or dense fog.
Expect a good soaking overnight with 0.25 to 0.5 inches across the region..
6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT
TOMORROW AND TOMORROW NIGHT
Key Messages
* Isolated to scattered showers on Wednesday * Cloudy with above normal temperatures upper 50s to low 60s
Showers associated with surface low pressure moving over the Northeast diminish for a time tomorrow morning as a warm sector air mass moves over our region. Strong synoptic forcing will continue to support precipitation chances for much of the day, but a mid-level dry slot will suppress any widespread/ persistent precipitation tomorrow. Expecting mainly isolated to scattered light showers. Conditions will be muggy for mid- November with temperatures and dewpoints in the upper 50s to lower 60s. Any shower activity should begin to wane during the mid-afternoon hours.
Tomorrow a night, a surface cold front pushes through region with 925 hPa temps plummeting to -5C.
This will result in cold/blustery conditions tomorrow night into Thanksgiving morning with lows generally in the mid to upper 30s. Winds become westerly from 10-20 mph with some higher gusts..
THURSDAY THROUGH TUESDAY
Key Messages...
* Colder and Blustery Thursday - Saturday
* Slight chance of snow showers Friday mainly in the higher terrain
* Moderating temps with an increasing chance for precipitation for the second half of the weekend
Still looking dry albeit colder and blustery for the Thanksgiving holiday. The cold and gusty conditions look to continue through Saturday as a much colder airmass moves in. Strong cold advection behind frontal passage allows for steepening lapse mid and low level lapse rates early Thurs morning. Increasing pressure gradient behind departing low pressure strengthens the LLJ to 30-40kts thus gusts rise to as high as 30-35 mph Thursday afternoon. Strongest winds arrive Friday as the LLJ increases to 45-50kts.
Expecting widespread gusts to 35-45 mph especially in the higher terrain. Winds wind down Saturday as high pressure moves overhead but remain breezy.
As mentioned earlier, Wednesday night's frontal passage will usher in a much colder airmass with 850 mb temps falling as low as -10C Friday into Saturday. Surface high temps will struggle to rise into the lower 40s for much of the area, and perhaps even the mid 30s for the higher terrain. Coldest temps will likely be Sunday morning if mid and high level clouds can hold off until closer to sunrise. Should be mainly dry for most locations through the weekend, though we can't rule out areas of snow showers Friday with any lake effect streamers. Better chance for meaningful precipitation arrives later Sun into Mon with an approaching frontal boundary..
Forecaster Confidence Levels...
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
06Z update...
Through 12z...Moderate Confidence.
MVFR ceilings and RA continue over the region. Ceilings IFR/LIFR MVFR/IFR vsbys in RA.
Today...High confidence in trends, moderate in timing
Widespread RA comes to an end by 12Z. Additional showers possible for much of the day especially over southeast MA and RI. Other terminals stay dry, especially after 18Z. IFR more than likely persists through the day, with some improvements to VFR/MVFR ceilings possible by 15-17Z but confidence is low in improvement.
Tonight...High Confidence
Cold front crosses the region tonight and clears skies from west to east between 03Z and 09Z. Winds shift to the west from 10 to 15 knots with some 25 knot gusts possible near the coast.
Thanksgiving...High Confidence.
VFR. W winds 10-15 kts with gusts 25 to 35 kts.
KBOS Terminal...Moderate confidence in TAF.
Biggest area of uncertainty is when/if cigs rise above IFR today; most likely remaining low MVFR if we do see some marginal improvement after 16z.
KBDL Terminal...High confidence in TAF.
Outlook /Thursday through Sunday/...
Thursday Night through Friday Night: VFR. Windy with gusts up to 35 kt.
Saturday: VFR. Windy with local gusts up to 30 kt.
Saturday Night: VFR.
Sunday: Mainly VFR, with areas MVFR possible. Breezy. Chance RA.
Forecaster Confidence Levels...
Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.
Through Wednesday Night...High Confidence
A low pressure moves over the coastal waters tonight with a period of steady rain. Increasing dewpoints may result in localized dense fog development over the cooler ocean waters. Showers and fog dissipate tomorrow night into Thursday as a cold front crosses the waters with a much cooler/drier air mass.
Outlook /Thursday through Sunday/...
Thanksgiving Day: Low risk for gale force winds with gusts up to 35 kt. Areas of rough seas.
Thursday Night: Moderate risk for gale force winds with gusts up to 35 kt. Areas of rough seas.
Friday: Moderate risk for gale force winds with gusts up to 40 kt. Rough seas up to 12 ft. Slight chance of rain.
Friday Night: Strong winds with gusts up to 40 kt. Rough seas up to 13 ft.
Saturday: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Local rough seas.
Saturday Night: Winds less than 25 kt.
Sunday: Low risk for Small Craft Advisory winds with gusts up to 25 kt. Chance of rain.
