SYNOPSIS
A couple of weak disturbances will bring scattered showers at times late tonight into Wednesday with a few thunderstorms possible Wednesday. Cooler than normal temperatures Tuesday will be followed by a warming trend with hot and humid conditions Thursday. The heat and humidity will be accompanied by a chance of thunderstorms, some severe possible, late Thursday and Thursday evening ahead of a cold front. Then more seasonable and drier conditions follow for Friday and Saturday.
Looking ahead to early next week, it appears significant heat may impact southern New England.
NEAR TERM /UNTIL 6 AM TUESDAY MORNING/
Key Messages:
* Stratus and patchy fog redeveloping
* Scattered showers possible late
Weak mid level ridging will set up over New Eng tonight with weak large scale subsidence for most of the night. However, deepening moisture plume approaches from the west ahead of a weak shortwave so scattered showers may develop late tonight from west to east.
Otherwise, ridging at the surface will extend west across SNE with continued low level SE flow providing abundant low level moisture.
Result will be stratus and patchy fog redeveloping and expanding across the region tonight. Lows will range from 55 to 60.
SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/
Key Messages:
* Lots of clouds with scattered showers at times Tue and Tue night
* Below normal temps Tue but increasing humidity
Tuesday and Tuesday night...
Unsettled pattern developing as a couple weak shortwaves will be moving through. Meanwhile, an area of deep moisture sets up across SNE with anomalous PWAT plume increasing to 1.75 to 2 inches.
Forcing for ascent is weak but enough forcing acting on high moisture will lead to scattered showers moving through. Timing of these showers is uncertain and not expecting a washout, but there will be showers at times Tue into Tue night. Not expecting any thunder but may see some convective showers developing as stability decreases.
Otherwise, expect gloomy conditions with lots of stratus through the period. The cloud cover and SE flow will result in cooler than normal temps Tue with highs upper 60s to lower 70s. Dewpoints will be climbing into the low and mid 60s so there will be somewhat of a humid feel to the airmass. A milder night Tue night with lows in the lower 60s.
LONG TERM /WEDNESDAY THROUGH MONDAY/
Key Messages:
* Becoming hotter each day through Thursday, then cooling off a bit Friday through the weekend before our hottest stretch of the year early next week.
* Severe weather possible on Thursday, greatest risk is damaging winds
* Dry Friday and Saturday but chance for some showers at some point in the weekend.
Wednesday and Thursday...
The return of more summer-like warmth comes Wednesday as southern New England will be sandwiched between high pressure over the Atlantic and low pressure moving through the Great Lakes. This places us beneath warm, moist SW flow until a cold front sweeps through late Thursday. Before this, 925 temps reach 20C on Wednesday and near 25C on Thursday which should lead to high temperatures in the 80s and upper 80s/low 90s respectively. It will also feel very humid as dewpoints surge into the upper 60s Wednesday and even low 70s potentially by Thursday. Not only will this increase the apparent temperatures, it will contribute to a great amount of instability on Thursday; guidance indicates several thousand J/kg of MUCAPE available. This, combined with mid level lapse rates approaching 7 c/km and 30-40 kts of 0-6 km bulk shear will lead to a decent chance of severe weather on Thursday. SREF guidance indicates a 40-50% probability of CAPE > 1000 J/kg and bulk shear >30kts, maximized over western and central SNE. Timing and severity will depend on several factors, including how quickly that cold front moves through. At this point the ECMWF would indicate a quicker passage, closer to the peak heating of the day while the GFS is slower, after sunset. Stay tuned.
Friday through early next week...
Friday into the weekend we'll be under drier W/NW flow and with a lingering trough/cyclonic flow aloft leading to some diurnal clouds Friday and potential for a weak shortwave moving through around late Saturday/early Sunday which may bring some showers but confidence is low at this point. What is more certain is that the pattern will be changing as we go into next week with high confidence of a building ridge and very hot temperatures for the first half of next week. At this point both the EPS and GEFS indicate a 70+% chance of 90+F on Monday and a near certainty by Tuesday.
AVIATION /20Z MONDAY THROUGH SATURDAY/
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18z TAF Update:
Through 00z...
VFR, but areas of IFR stratus possibly developing along the immediate coast 22-00z.
Tonight...Moderate confidence.
IFR-LIFR stratus developing along the immediate coast this evening then expanding inland across much of the region overnight. Exact timing uncertain. Patchy fog developing.
Scattered showers possible late tonight. Light E wind.
Tuesday and Tuesday night...Moderate confidence.
IFR-LIFR in the morning improving to MVFR in the afternoon, then lowering back to IFR-LIFR Tue night. Scattered showers, especially interior. E-SE wind 5-15 kt becoming light south Tue night.
KBOS Terminal...High confidence in trends. Lower confidence in timing.
Expect stratus developing 00-02z eventually lowering to LIFR with areas of fog by 06z. A few showers possible late tonight into Tue. Cigs possibly improving to MVFR Tue afternoon.
KBDL Terminal...Moderate confidence in TAF.
Expect IFR stratus developing after 04-06z lingering into Tue.
Cigs possibly improving to MVFR Tue afternoon.

Forecaster Confidence Levels:
