SYNOPSIS
Today is the cornerstone of a pattern change towards more mild conditions though clouds and cool temperatures will still hang across the Cape. Much milder conditions Tuesday with heat peaking on Wednesday. Frontal passage Thursday, with increased thunderstorm chances, will usher in more seasonable temperatures for the holiday weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/

130 PM Update...

* Plenty of sunshine this afternoon away from the Cape/Islands * Highs 60s immediate coast, 70s inland, near 80 CT River Valley

Clouds have scoured out across most locations northwest of I-95 as of early this afternoon allowing for plenty of sunshine.
Still some low clouds across southeast of I-95 but expect partial sunshine to emerge in this region shortly...with perhaps the exception of the Cape and Islands where low clouds may hang tough.

Light onshore flow will hold highs in the upper 50s/60s on the immediate coast, but 70s just a bit further inland, and near 80 in the lower CT River Valley.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/

Patchy fog development is possible again tonight though developing SW winds around 5-10kt, and dewpoint depressions around 4F should preclude widespread fog across the interior. With that said, the same mechanism of SW flow should encourage some fog/reduced vsbys along the South Coast and Islands where both temps and dewpoints hover around 50F and SSTs are in the low to mid 50s.

With surface high still in place and mid level ridge growing stronger, guidance is still quite poor in diagnosing cloud cover for Tuesday, with several CAMs, like the HRRR, showing a mostly cloudy day. Not feeling particularly keen on the "cloudy all day" solutions with PWATs falling to as low as 0.7" and low RH above the mixed layer, but early morning fog/stratus, particularly along the south coast, may take a few hours to burn off. Decent boundary layer mixing with 850mb temperatures approaching 16C will support highs well into the 80s across much of the interior, though onshore flow across the south coast will keep temps much cooler there, in the 60s to perhaps 70s. Given SW flow, Boston MAY see their first 80F reading of the season, and while it's possible the ASOS may not hit 80F, the western suburbs of the city have a high likelihood of doing so.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/

Highlights:

* Peak of the midweek very warm weather is Wednesday - 80s highs with a few locations in the CT and Merrimack Valleys seeing a few 90 degree readings. Tolerable humidity levels.

* Cold front Thursday afternoon to early evening brings a reprieve to the warmth but also could fuel scattered t-storms.

* Drier and with cooler, more seasonable temperatures Friday into the Memorial Day Weekend.

Details:

Still looking at Wednesday as the warmest day of the anticipated midweek spell of very warm temperatures reminiscent of summer. 850 mb temps rising into the +14 to +16C range along with full mixing and southwest breezes should promote these very warm temperatures.
NBM probs continue to show moderate to high (60 to 90 percent) probs of temps reaching 90+ degrees in the CT and Merrimack Valleys, with lower (no greater than 30%) probs of 90+ high temps in central MA, northeast CT and portions of Metrowest. These are a bit higher than the prior 13z NBM cycle. The one thing that is a little peculiar in the NWP is that modeled dewpoints were shown to be in the lower to mid 60s across a good majority of the guidance; I don't think values this high are necessarily realistic given the well mixed PBL and adiabatic downsloping that should be taking place per model soundings. That's also a concern/source of uncertainty as we move into Thursday as well. Advertised highs upper 80s to low 90s in the CT and Merrimack Valleys - although those could be somewhat conservative - and the mid 80s for most of northern RI, central and eastern MA. Cooler readings near the south coast (upper 60s-mid 70s)
where SW flow will allow for a bit of a maritime breeze. Should be a pretty mild Wednesday evening too, mid 50s to lower 60s, but did note some of the guidance showing weakening convection moving in from eastern NY into our far western counties in MA later in the overnight. Left a slight chance PoP mention in the forecast for now for the eastern Berkshires but we'll have to see if this materializes in subsequent guidance.

A cold front then trudges eastward through Southern New England on Thursday. It seems as though in the 00z guidance that the front is about 6 hours slower than prior model cycles; that may allow for another very warm day with a slower timing, but also could allow for slightly more convective instability to help spark showers/t-storms along the front, particularly near and west of I-95. Similar to Wednesday, models are now forecasting dewpoints in the lower to mid 60s although those seem a bit high. If we can see dewpoints push into the lower 60s, we could see CAPE values around 800-1500 J/kg accompanied by deep-layer southwesterly shear magnitudes around 35 kt (stronger flow mainly to our north). This is really on the borderline for storms becoming strong to severe and doesn't really scream "severe storms", but is something we'll be needing to monitor in the coming days. Kept highs in the upper 60s/around 70 near the south coast, and in the upper 70s to mid 80s further inland.

For Friday, the cold front's southeastward passage further offshore could be delayed a bit as the front's orientation becomes nearly parallel to the 700-300 mb flow, which could keep clouds and showers around the south coast for part of the day. However high pressure is progged to ridge into much of New England, with ridging continuing into a good part of the Memorial Day Weekend. Temperatures Friday into the weekend trend cooler and more seasonable than midweek, with highs in the 70s (60s near the coast). Thus so far, weather conditions for Memorial Day Weekend seem favorable.

AVIATION /17Z MONDAY THROUGH FRIDAY/

Forecast Confidence Levels:

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

18z TAF Update...

This afternoon...High Confidence.

Low clouds have scoured out to the northwest of I-95 yielding VFR conditions early this afternoon. Still MVFR ceiling southeast of I-95...but probably see temporary improvement at least away from the Cape and Islands over the next few hours.
Light E winds generally becoming more SE-S in many spots toward evening.

Tonight...High Confidence in trends but lower confidence in specific timing.

Low end MVFR to IFR/LIFR conditions will ovespreads area near the Springfield
to Worcester to Beverly corridor
but may struggle to get too far northwest of that region. The greatest risk for LIFR conditions will be across RI/SE MA where low clouds arrive earlier and there also will be fog developing...which may become locally dense. Calm/light S winds.

Tuesday...High Confidence.

Low clouds and fog patches should burn off Tuesday morning. This process will probably be faster than today...given more of a S-SW winds 10-15 knots. May also see a few hours of localized sea breezes along the very immediate coast...but this should be overcome during the afternoon as gradient strengthens.

Tuesday night...Moderate Confidence.

Low clouds and fog patches will probably redevelop Tue night...but probably only impact areas south of I-90 with the best chance across RI/SE MA. Surface winds out of the SW at 5-15 knots will probably keep the low clouds/fog from becoming as extensive and spreading as far north as tonight.

KBOS TAF...High confidence in trends but lower confidence in timing. Thinking low clouds with low end MVFR to IFR conditions return after 02z or so tonight and burn off by mid-morning Tue.

KBDL TAF...High confidence in trends but lower confidence in timing.

Outlook /Wednesday through Friday/...

Wednesday through Wednesday Night: VFR. Breezy.

Thursday: VFR. Breezy. Slight chance SHRA, slight chance TSRA.

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

Friday: VFR.

MARINE

Forecaster Confidence Levels:

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

Today... 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.

Tuesday... high confidence

AM fog will burn off to pleasant boating conditions. SW winds with seas less than 5 ft.

Outlook /Tuesday Night through Friday/...

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

Thursday: Winds less than 25 kt. Areas of seas approaching 5 ft.

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

Friday: Winds less than 25 kt. Slight chance of rain showers.

BOX WATCHES/WARNINGS/ADVISORIES
CT...None.
MA...None.
RI...None.
MARINE...Small Craft Advisory until 2 PM EDT this afternoon for ANZ254.
