SYNOPSIS
The coastal storm that has brought low clouds, drizzle and cool northeast winds to RI and eastern MA, finally begins to exit out to sea tonight. This gives way to a significant pattern shift to drier and warmer weather beginning Monday. Very warm temperatures are expected on Tuesday and Wednesday, with temperatures reaching into the 80s, with an outside chance a few locations see 90 degrees on Wednesday. Humidity levels will be on the low side accompanying that midweek warmth, hence, a somewhat dry heat. A cold front arrives on Thursday with the potential for showers and thunderstorms. A more seasonable air mass then filters in for late in the week into at least the early part of Memorial Day Weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
3 PM Update:

Low level moist onshore jet continues to deliver overcast conditions and some spotty drizzle across RI and eastern MA, including Cape Cod and the Islands. Meanwhile, breaks in the overcast are occurring across CT into MA, eastward into the Worcester Hills. Temps are responding to the strong May sunshine, with temps warming through the 60s there and a few low 70s, including 71 at BDL currently. Meanwhile, short wave energy traversing southward from the ME coast will continue to delay height rises from advancing eastward today. This also results in a nearly stationary low level ENE jet into eastern MA and RI, with the low level jet slowly shifting southward overnight, along with ridge of high pressure advecting south into SNE.

Thus, drier trends overnight. However, low level moisture will likely remained trapped beneath the subsidence inversion from the surface ridge building southward. Hence, low clouds will remain stubborn across RI and eastern MA tonight and likely drifting back into CT and western/central MA, along with patchy fog possible. This low level moisture will yield seasonably cool temps overnight, with lows in the upper 40s and lower 50s.
Although, it will feel cooler with northeast winds 15-25 mph, highest over southeast MA and RI, slowly slackening tonight as the surface ridge builds southward.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/
3 PM update...

* Big improvement, more sunshine & warmer temperatures * Low 80s possible CT River Valley, including Hartford/Springfield

Monday...

Once short wave energy exits the eastern MA coast tonight, this allows height rises to advect Monday across the region from west to east and more importantly, low level jet easing and moving offshore.
This ridging and associated subsidence will allow strong May sunshine to erode low level moisture/clouds and possible patchy fog Monday morning and give way to at least partial afternoon sunshine to the entire region. 12z models have trended warmer and this seems reasonable given the height rises and morning clouds giving way to at least partial late May sunshine. 850 mb temps increase to about +12C and 925 mb temps warm to +18C to +20C western MA, to +13C across southeast MA. This will support highs in the low 80s across western MA/CT, with much of the region seeing highs in the 70s and as far southeast into the I-95 corridor of MA/RI. With surface ridge over the area, afternoon seabreezes will develop and cap highs in the 60s for the coastline, possibly only into the upper 50s for the outer Cape and Nantucket.

Monday night...

Deep layer ridge over SNE will provide dry weather. Light winds and dew pts slightly above normal (low 50s), may yield patchy fog. This will also result in mild overnight temps, with lows 50-55.

LONG TERM /TUESDAY THROUGH SUNDAY/

No big changes here, a warming trend continues Tuesday and Wednesday with the chance for this summer-like warmth to continue on Thursday.
A cold front moves across the region on Thursday, perhaps bringing a few stronger storms. Mixed signal heading into next weekend as the deterministic guidance remains split over a dry or semi-wet weekend.

An anomolously warm air mass, driven by a modest mid-level ridge, is expected to linger over much of New England into Thursday, leading to well above normal surface temperatures. Global guidance suggests 850mb temperatures are +6C to +11C above what is normal over the course of those three days. The ridge does break down late Thursday into Friday a mid-level trough swings through.

Tuesday afternoon there are high probabilities, greater than 80% for temperatures AOA 85 degrees, locations like Hartford, Springfield, Worcester, and Lowell. Many spots across the interior top out between 85F-89F, while closer to the coast a southwest wind keeps locations south of Providence/Taunton/Plymouth in the 70s, though the immediate coastline in the upper 60s. Wednesday looks to be the warmest day with a large portion of northern Connecticut, northern Rhode Island, and much of Massachusetts (outside of southeast MA)
with greater than 80% probabilities of afternoon temperatures AOA 85 degrees. It is not out of the question we have a few spots pushing 90 degrees, places in the Merrimack and CT River Valley have a greater than 70% chance. While less likely, there are even low probabilities of temperatures at or above 95F, around 40% in the Merrimack Valley. Thursday, the maximum temperatures will really depend on what time a cold front moves through and how much cold cover develops. Given the uncertainties, continues with NBM guidance, highs likely reach back into the middle 80s away from the coast. Temperatures turning more seasonable with highs in the 70 for Friday into next weekend.

Much of this week is dry, the mid-level ridge does support a drier pattern. Not out of the question there could be a rouge afternoon shower/thunderstorm mainly areas northwest Massachusetts, but the better chance for showers is Thursday. Guidance is in pretty fair agreement a cold front moves across the region with the potential for thunderstorms - whether or not they are severe is still to be seen, but there are signs that the atmosphere could be favorable with modest CAPE, 1500 J/kg and effective shear of 40 kts. Based off the previous deterministic run, the CSU machine learning have 5% to 15% of severe weather, something to monitor as we head into this week. Drying out on Friday, but there remains uncertainty with this upcoming weekend whether or not we see rain or not.

AVIATION /20Z SUNDAY THROUGH FRIDAY/
Forecast Confidence Levels:

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

18z TAF Update:

Through 00z...

Improving cigs to MVFR continue to spread from west to east across CT and MA into the Worcester Hills, RI and even into parts of southeast MA. Some uncertainty how much farther eastward this progresses before sunset. Radar still picking up some spotty drizzle across southeast MA into RI. This should slowly shift south through 00z. NE winds 10-15 kt with gusts up to 25 kt across Cape Cod and the islands.

After 00z...

Decreasing trends with IFR (possibly LIFR) cigs and MVFR vsbys in fog drifting and developing westward from the coastline into the interior overnight. Any areas of drizzle during the evening should come to an end after midnight. NE winds 10-15 kt with gusts up to 20 kt in the evening across southeast MA, will slacken overnight.

Monday...

IFR/LIFR cigs with mainly MVFR vsbys in fog early, will slowly improve to VFR all terminals, but obviously delayed until the afternoon or late in the day across Cape Cod and the Islands. Light NE winds become east and then southeast late in the day.

Monday night...

VFR but MVFR vsbys developing in patchy fog.

KBOS TAF...High confidence in TAF trends but lower on exact timing.
MVFR cigs and VFR vsbys this evening, then lowering to IFR/LIFR cigs with MVFR vsby overnight into Monday morning. Then eventually improving to VFR by Monday afternoon. NE winds tonight, becoming east Monday and then southeast late in the day.

KBDL TAF...High confidence in TAF trends but lower on exact timing.
VFR continues into early evening, then some uncertainty how low cigs and vsbys overnight into Monday morning, as low clouds and patchy fog develop overnight. High confidence in improving conditions Monday to VFR by midday or so.

Outlook /Tuesday through Friday/...

Tuesday through Tuesday Night: VFR.

Wednesday through Wednesday Night: VFR. Breezy.

Thursday: VFR. Breezy. Chance SHRA, chance TSRA.

MARINE
Forecaster Confidence Levels:

Low - less than 30 percent.

High - greater than 60 percent.

3 PM update...

Tonight...high confidence.

Offshore low continues to generate marginal SCA with NE winds up to 25 kt (in gusts, not sustained) and seas up to 6 ft across the eastern MA waters, slowly subside tonight. Vsby may be reduced to 1- 3 miles at times in drizzle and fog.

Monday... High confidence

Lows clouds/drizzle and patchy early morning fog with vsbys 1-3 miles, slowly burns off with improving conditions mid to late afternoon. High pressure over SNE results in light NE winds become east and then southeast late in the day.

Monday night...high confidence.

Ridge of high pressure crest over the waters, yielding light SE winds becoming SW. Patchy fog may limit vsby at times.

Outlook /Tuesday through Friday/...

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

Thursday: Winds less than 25 kt. Seas locally approaching 5 ft.
Slight chance of rain showers, isolated thunderstorms.
