Synopsis for massachusetts and rhode island coastal waters - Dry and calm conditions continue this weekend as high pressure builds in. High pressure looks to remain in control to start next week with the next chance for precip at the end of next week.

Area Forecast Discussion National Weather Service Boston/Norton MA 127 AM EDT Sat Jun 1 2024
SYNOPSIS
High pressure over the Ohio Valley Friday builds slowly east this weekend and crest over New England Sunday. This will provide dry weather along with warm days and cool nights. The next chance of showers, albeit very low, is Sunday night as weak low pressure tracks south of the region. High pressure brings warm and dry weather through the middle of next week, then the weather pattern becomes unsettled toward the end of the week as a frontal system approaches from the west.
NEAR TERM /THROUGH TODAY/
10:30PM - No forecast changes, see 7pm discussion for details.
7 PM update...
Diurnal CU is dissipating but batch of mid level clouds are rotating south across eastern half New Eng this evening. These clouds are reflected in mid level RH fields which show moisture pushing off the coast later this evening. Clear skies will follow setting the stage for good viewing conditions tonight for the possible aurora. Visit swpc.noaa.gov for more information regarding the possible magnetic storm. Dry NNW flow aloft will maintain a very dry airmass across SNE, with dew pts in the 30s and 40s. This combined with mostly clear conditions and a weak NW pressure gradient, will support another night of chilly temps. Thus, we will lean toward the cooler MOS guidance to derive lows tonight, mainly in the mid to upper 40s in the suburbs. Low to mid 50s elsewhere, including the city of Boston and the high terrain, where winds will likely not decouple.
Don't think we will see much if any patchy fog tonight given the dry airmass, with dew pts as low as the mid to upper 30s at 2 pm.
SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/
230 PM update...
* More fabulous weather, sunshine and warm but low humidity
Saturday...
As we flip the calendar to June 1st (opening day for hurricane season), our dry, pleasant weather continues. This is courtesy of closed low over the Maritimes combined with ridge axis over the eastern Great Lakes, continuing to provide a dry NNW flow/airstream across SNE. Almost a rinse and repeat weather pattern from today.
Hence, lots of sunshine and another nice temp recovery from morning lows in the 40s and 50s, warming into the upper 70s and lower 80s, along with comfortable humidity (dew pts in the 40s!). Another day of spectacular weather. Only wrinkle to the forecast is possible afternoon seabreeze for eastern MA. As closed low exits the maritimes and dives southward, shallow cool air spreads across the Gulf of ME and westward toward MA. This cooler air just offshore combined with a weakening pressure gradient supports seabreeze/cool maritime air to come onshore. Thus, could have temps falling through the 70s and into the 60s during the afternoon along the coast.
Otherwise, another gorgeous day on tap for MA/RI/CT.
Saturday night...
Deep layer ridge crest over the region Saturday night into Sunday morning, continuing our dry and cool weather pattern. Not as chilly as previous nights but still cool for early June. Followed the cooler MOS guidance to derive mins, with forecast lows mainly in the 50s, but a few upper 40s in the normally cooler suburbs. Dew pts not quite as low as today, therefore patchy fog is possible.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
Key Points...
* Warm and mainly dry weather through the middle of next week
* Unsettled pattern late in the week with increasing risk of showers
Details...
Warm and mainly dry conditions expected through the middle of next week as mid level ridging in control for much of this period. Weak shortwave moving east from the Gt Lakes temporarily breaks down the ridge on Sunday but not expecting much more than some extra cloud cover as column moisture is limited. For Sun night, another shortwave and area of enhanced moisture is forecast to track mostly south of New Eng. There is a low risk for a few showers near the south coast but bulk of rainfall will likely remain to the south.
Otherwise, dry through Wed with above normal temps well into the 70s to lower 80s, but cooler along the immediate coasts due to sea- breezes.
Forecast uncertainty increases toward the end of the week as amplifying trough digs into the Gt Lakes with shortwave energy rotating around the trough. Shower chances will be increasing but timing and extent of showers and rainfall amounts are uncertain as there are significant model differences with the timing of the front and where a potential frontal wave develops. We followed NBM guidance which indicates chance of showers both days and cooler temps.
AVIATION /06Z SATURDAY THROUGH WEDNESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.

Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Today through Sunday... High confidence.
Very pleasant boating conditions, with weak high pressure slowly building east and cresting over New England early Sunday. This will provide light winds, locally onshore along with dry weather and excellent vsby to the horizon. The only negative, is that water temps remain chilly, only 55-60 degs.
Outlook /Sunday Night through Wednesday/...
Winds less than 25 kt.
