SYNOPSIS
Unsettled and cool today with scattered showers. Chance for improvement on Sunday as high pressure begins to nudge in from the southwest. Early summerlike temperatures expected Monday through Wednesday, with the warmest days expected to be Tuesday and Wednesday. A cold front around Thursday offers the next chance at showers or thunderstorms, with temperatures then cooling to more seasonable levels by late in the week.
NEAR TERM /UNTIL 6 PM THIS EVENING/
Today we remain under the influence of pesky mid level low to our south that has brought unsettled conditions to southern New England for the last several days. With low to our south, weak shortwave lifts from the Great Lakes into northern Maine by late this evening.
Given southern New England is "sandwiched" between the shortwave and the low, we'll have a few chances for showers today; actually, the first chance for showers is already underway with light precipitation backing in across the Cape and Islands, thanks to persistent ENE. Showers will become more widespread after 15Z today as PWATs surge to >1.0", aided by a weak 925mb jet of 20-30kt draped over eastern MA. General thinking is showers are possible in any location, but will be more widespread east of the Worcester metro area. In fact, the CT River Valley may "luck out" with a primarily dry day as weak high pressure attempts to nudge in from the southwest. While it will a dreary and rather chilly day, with little to no diurnal swing in temps from current obs (in the 50s and low 60s, west), QPF will be minimal, with HRRR ensemble mean QPF around 0.1" across Middlesex and Essex Counties. Should high pressure be able to scatter out a few breaks of sunshine across western MA, could see temps warm briefly into the mid to upper 60s in places like Hartford and Springfield.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/
Pattern of persistence carries through this evening with little change in the synoptic setup through early tomorrow morning.
Shortwave passing to our Northwest may renew shower activity between 00-06Z tonight. Widely scattered shower activity across the eastern half of the CWA will become increasingly sparse after the midnight hour, giving way to a more drizzle-stratus dominated environment by early morning. Temps will pretty much remain stagnant overnight given no change in the pattern with low sin the 50s.
While Sunday previously looked to be a much nicer day for southern New England, there are indications that the influence of onshore flow will persist through the better part of the day across eastern MA and RI, though conditions should improve across CT and western MA as weak high pressure is able to take better hold over the region.
Fortunately, pesky mid level low tracks seaward, which will allow rain chances to decrease significantly by sunrise. As has been the case with many days this Spring, it's likely Sunday is another case of the "haves and have nots", as the CT River Valley breaks out into sunshine and temperatures warm into the low 70s while strong onshore flow pins stratus across eastern MA and much of RI where temps struggle to climb out of the 50s along the immediate coast. It's probably safe to say those in the Boston to Providence corridor are ready to shake this gloomy pattern, but fear not, the long term AFD highlights a significant pattern chance by mid week!
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Highlights:
* Warming temperatures under partly to mostly sunny weather through midweek, with the warmest days likely on Tuesday and Wednesday.
Could have our first 80 degree day in Boston Tuesday and/or Wednesday, with 3 days of lower-mid 80s in Hartford.
* Our next chance for rains is around later Wednesday night or Thursday with showers or thundershowers associated with a cold front.
* Cooling to more seasonable levels for late-week.
Details:
While the general theme of a substantial warming trend to temperatures for the early to midweek period is still valid, today's 00z guidance indicated more potential for continued cloud cover on Monday with higher RH in the 1000-850 mb layer, especially for eastern and southeast New England. Ended up bringing highs down from NBM by a couple degrees for Monday on the basis of this cloud cover, though the temperature forecast has obvious sensitivities to how long clouds linger/scatter out, and that is still a bit unclear.
Kept highs in the mid 50s to mid 60s for the coasts and the coastal plain, but still think highs soar into the mid to upper 70s from central MA/eastern CT westward with less cloud cover.
Warmest days look to be on Tuesday and Wednesday, with full sunshine, southwest breezes and continue dry weather. Relatively strong SW flow should keep sea breezes from making much of any intrusion landwards, so even sites such as Boston and the North and South Shore have a solid chance at reaching 80 degrees, having last occurred at Boston on October 28th of last year. Mid 80s inland seem reasonable on both days. Despite the breezes, both days should feel more reminiscent of early summer with dewpoint temps in the mid to upper 50s.
Dry weather to prevail through Wednesday. Our next chance for showers or thundershowers isn't until a cold front arrives around Wednesday night or Thursday, but the timing and the strength of any thunderstorms are both uncertain. Latest guidance favors Thursday for frontal passage so favored the highest PoP around Thursday but only around 20-30 percent given the uncertainties in timing. Friday appears to be more entrenched in post-frontal colder air, with temps seemingly poised to return closer to late-May climatological levels.

Scattered rain showers, primarily from Worcester, east, at any point today, with greatest chance for widespread shower activity between 15-00Z. It is possible that portions of the CT River Valley remain VFR all day with cigs around 040. NE Winds 5-15kt with a few gusts to 20kt possible along the immediate eastern coastline.
Saturday Night...Moderate confidence.
Conditions remain consistently MVFR to LIFR from West to Southeast, lowest on the Cape and Islands. Light showers and drizzle continue through the first half of the evening. MVFR to IFR conditions persist due to pesky onshore flow. Winds continue to blow from the E/ENE gusting to around 10-15kt overnight.

Conditions improve from west to east after sunrise from MVFR/IFR to VFR/MVFR. VFR possible for BOS-PVD line, SE after 18Z, though MVFR to hang on across the Cape for the duration of the day. NE winds gusting 15 to perhaps 20kt once again.
KBOS TAF...High confidence in TAF through 00Z. Moderate after this time.
VFR degrading to MVFR after 10Z this morning as shower activity increases. IFR this afternoon. NNE/NE flow 10-15kt with the occasional gust to 20kt possible. Forecast of persistence, with little change in conditions over the next 24 hours.
KBDL TAF...High confidence in TAF.
