Synopsis for massachusetts and rhode island coastal waters - Maritime high pressure remains over the ma and ri waters into Sunday, yielding tranquil boating weather. Then a cold front sweeps across the waters late Sunday into Monday morning, accompanied by numerous showers and areas of fog, lowering vsby 1 to 3 miles at times. The front moves offshore Monday afternoon, followed by wnw winds, dry weather and good vsby through Tuesday. This tranquil boating weather may linger through much of Wednesday, before a warm front approaches from the southwest late Wednesday into Thursday.

SYNOPSIS
High pressure supplies dry weather with cooler onshore breezes today and Saturday. Increasing clouds Saturday night with showers likely and cooler temperatures Sunday into Sunday night.
High pressure then brings dry and warm weather Monday afternoon into Tuesday. Unsettled weather is possible later Wednesday into Thursday, with the risk of showers but likely remaining mild.
NEAR TERM /UNTIL 6 PM THIS EVENING/
A blanket of low clouds across the region, with the exception being over western MA/CT, where breaks in the overcast are occurring per latest visible satellite imagery and surface observations. This low level moisture is trapped beneath subsidence inversion across the area, courtesy of 1020+ maritime high. However, strong May sunshine will slowly erode the clouds and give way to breaks of afternoon sunshine, especially mid to late afternoon.
Seasonable temps but feeling cooler across eastern MA with maritime NE flow, capping highs in the 50s this afternoon, response to water temps only in the 40s. Also, low level NE jet currently yielding gusts up to 25 mph over Cape Cod and the Islands, will diminish this afternoon. Hence, less wind this afternoon than this morning. Previous forecast captures these details nicely, therefore no major changes with this update.
Earlier discussion below.
Previous Discussion...
A broad anticyclone centered to the north/northeast of southern New England takes control today. A steady northeast flow will advect a cooler air mass over southern New England this afternoon with 925 hPa temps dropping to 5C or lower. With diurnal mixing this will translate to surface temps in the low to mid 60s across the interior and mid to upper 50s along the coast. Downsloping from easterly flow over The Worcester Hills will support warmer temperatures in the upper 60s in the CT River Valley. After a cloudy start, a mid-level ridge axis building in from the west will be accompanied by a much drier air mass that will allow some clearing my late morning/early afternoon. Still expect FEW to SCT diurnal clouds this afternoon, but there should be a good amount of sunshine as well. Overall a seasonable day in southern New England.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
Tonight and Tomorrow
High pressure supports dry/quiet weather across southern New England tonight. Winds become light and variable which should allow for fairly efficient radiational cooling across the region, though there is a question as to how much cloud cover there will be and thus cooling potential. Decided to blend the NBM25th percentile with CONSMOS to yield low temps in the low to mid 40s which is near to slightly below normal for early May in southern New England.
High pressure remains in control on Saturday, so we continue to expect dry/quiet weather. However, continued onshore flow will support cloudiness across the region. Very little change in the air mass for Saturday, so expect high temperatures similar to what should be observed Friday afternoon with cooler temps along the coast in the mid 50s and warmer temps across the interior and CT River Valley ranging from the low to upper 60s.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Highlights:
* Cool but dry Saturday night into Sunday, then numerous showers Sunday afternoon into Monday morning.
* Dry & warm Monday afternoon into Tuesday
* Showers possible late Wed/Wed night into Thursday.
Synoptic Overview...
Tranquil stretch of weather in response to east coast ridging/above normal heights much of this forecast period. A brief interruption to the pattern, as northern stream trough briefly erodes this ridge with a risk of showers later Sunday into Monday morning. Then dry post frontal NW flow returns later Monday and into Tue. Progressive pattern follows with ridge building back into the northeast, but may be accompanied by warm frontal showers later Wed/Thu.
Temperatures...
Cool maritime ridge Sat night into Sunday, with lows in the 40s and highs 55-60. 850 mb ensemble temp anomalies peak 18z Monday over southeast MA, in the transition to post frontal. Thus, looking at a warm day (provided clouds & showers exit before the PM hours) with WNW flow combined with warm temps aloft coupled with downsloping winds. Hence, coastline warms up too, including Cape Cod and Islands. Also, dew pts in the 50s will provide mild/warm feel to the airmass. Not much of a drop off in temps in the post frontal airmass, thus, another warm day Tuesday with NW flow, warm temps aloft combined with downsloping NW winds. Likely not as warm Wed/Thu but probably above normal(60s).
Precipitation...
High amplitude, deep layer ridge with 1030 mb high from the maritimes into eastern MA, provides dry weather Sat night into Sunday morning. Then approaching trough provides cyclonic flow and increasing/above normal PWATs yield numerous showers Sunday afternoon into Monday morning. Ensembles offering likely probs (60- 70% for 0.25 inches of rainfall, with chance probs (30-40%) for up to 0.50 inches of rainfall. Timing for widespread showers, highest PWATs from 06z-12z Monday per ensembles. Post frontal with dry slot during Monday afternoon. Drier than normal PWATs linger into Tue, then becoming unsettled Wed/Thu with moisture plume advecting across the region (PWATs up to 200% of normal). Too far out in time for details, but looking at height anomalies from the ensembles, anomalous lows over Newfoundland and the Dakotas, may result in a slower ridge advecting across SNE mid of next week. Thus, high amplitude pattern may support dry weather lingering thru much of Wed, especially eastern MA/RI.
AVIATION /18Z FRIDAY THROUGH TUESDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through 00Z...High confidence in trends, moderate in exact timing.
VFR across the CT River Valley, but still working on eroding the MVFR/borderline VFR conditions across central MA/RI into eastern MA. Should see these ceilings continue to lift/scatter out by roughly 19-21Z. This should take the longest across the Cape terminals, though think ACK remains MVFR through the forecast with onshore flow.
Tonight...Moderate confidence.
VFR conditions to start with light and variable winds. There is a possibility for MVFR stratus to spread back in with enough onshore flow aloft. Timing wise think it would be after 06Z.
Could see patchy fog across the typical prone areas in the Merrimack Valley, but have only hinted at for now.
Tomorrow...Moderate confidence.
Any lingering MVFR may improve to VFR for much of the day. Some uncertainty here given we are still stuck in persistent onshore easterly flow at 5-10 kts. Confidence higher for VFR away from eastern MA coastline.
KBOS TAF...High confidence this afternoon. Lowers to moderate tonight.
Improving to VFR by 19Z with NE to E winds. Winds light and variable tonight with enough onshore flow aloft that MVFR stratus could spread back in roughly 04-06Z. Could improve to VFR as boundary layer mixes roughly 13-15Z, but uncertain on this given the onshore wind component.
KBDL TAF...High confidence.
VFR through the forecast. Could see some borderline MVFR ceilings spread in 02-04Z tonight.
Outlook /Saturday Night through Tuesday/...
Saturday Night: Mainly VFR, with local IFR possible. Chance SHRA.
Sunday: Chance SHRA.
Sunday Night: Breezy. Chance SHRA.
Monday: Chance SHRA.
Monday Night through Tuesday: Slight chance SHRA.

Today through Tomorrow
High pressure supports fairly calm conditions across the coastal waters through Saturday. Winds will prevail out of the northeast from 10 to 15 knots with some gusts to 20 knots possible. Seas generally 1 to 3 feet.
Outlook /Saturday Night through Tuesday/...
Saturday: Winds less than 25 kt.
Saturday Night through Sunday: Winds less than 25 kt. Chance of rain showers.
Sunday Night through Monday: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers.
