Synopsis for the long island and connecticut coastal waters - High pressure along the new england coast weakens locally as it shifts farther offshore today ahead of an approaching cold front from the west. The front eventually tracks through the region late Monday, stalling to our south. High pressure then briefly returns before the stalled boundary returns as a warm front Tuesday night. A series of low pressure centers then impact the weather from Wednesday through Saturday.

Area Forecast Discussion National Weather Service Boston/Norton MA 649 AM EDT Sun May 5 2024
SYNOPSIS
Cloudy and cool weather is on tap for today with a period of widespread showers arriving from the west this afternoon and continuing overnight. Mild and dry to start the work week before cooler and unsettled conditions Wednesday through next weekend
NEAR TERM /UNTIL 6 PM THIS EVENING/
650 AM Update...
1030 mb high over the maritimes providing a cool and moist easterly flow across SNE. Meanwhile, warm air aloft is gliding over this shallow cool airmass. However, strongest thermal and moisture advection is across NY state into VT. Hence, rain shield is focused over this region. However, the ridge over eastern MA advects offshore today, showers to the west will slowly traverse eastward. Thus, a dry start for much of SNE, but it will be wet finish for most of the region, with Cape Cod possibly remaining dry much of the day. Otherwise, a cool day with east to southeast winds streaming across ocean temps in the 40s. Earlier forecast was capturing these details, therefore no major changes with this update. Earlier discussion below.
-------------------------------------------------------------------
Today
Southeast winds gradually shift south during the afternoon today.
Skies will be consistently overcast today which will limit high temperatures to the mid to upper 50s across the region. Shower chance will gradually increase into the mid-afternoon hours as a mid- level short-wave approaches from the west. Most areas stay dry today, but locations near and west of the CT River Valley may start to see some light showers in the 5 to 7pm time frame.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/
Tonight
Showers associated with an upper-level short-wave traversing over The Northeast spread west to east this evening. Expect widespread light showers across southern New England with new rainfall accumulations totaling 0.25 to 0.5 inches. Winds remain steady out of the south which will keep dewpoints elevated and support some patchy fog formation. Low temps will be bottom out early in the evening as southerly flow and low-level warm advection will begin to support increasing temperatures after midnight and into tomorrow morning.
Tomorrow
A substantial warm up tomorrow as southerly flow advects a near 15C air mass at 925 hPa over the region. Still expecting a good amount of low to mid-level cloud cover across the region for the first half of the day, but breaks of sun in the afternoon should support warm temperatures in the low to mid 70s across areas of southern New England away from the coast. Winds may be light enough to support a sea-breeze along the coastline which would result in cooler temperatures in the mid 60s.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
* Dry with warmer than normal temperatures Tuesday
* Cooler with periodic showers Wednesday thru Saturday
Temperatures...
Warm airmass over SNE with good model consensus of 925 mb temps ranging from +16C to +18C...and +10C at 850 mb. These temps aloft combined with good blyr mixing via strong/high May sun angle and a dry airmass (dew pts in the 40s) will support highs 75-80. Ensembles have 100% probability of 70+ temps away from the immediate coast Tue. These temps are much warmer than normal (60s) for early May.
Thus, a dry heat for Tue. A weak pressure gradient combined with ocean temps in the 40s, will result in a wicked seabreeze, hence much cooler along the coast, Cape and Islands. However, coastal locations including Boston, could briefly hit 70+ before the seabreeze arrives. Nonetheless, Tue definitely the pick of the week, then a pattern change develops around Wednesday and continues thru next weekend. A stalled frontal boundary sets up over or near SNE, yielding a cooler regime, with lots of clouds, onshore flow and risk of showers from time to time. Temps likely become progressively cooler each day, beginning Wed and continuing into next weekend.
Precipitation...
Any leftover scattered showers Monday evening associated with weak cold front, quickly come to an end as post frontal airmass overspreads the region later in the evening and overnight. Turning less humid Monday night, as dew pts fall from 55-60 into the upper 40s/low 50s by 12z Tue. Dry NW flow prevails Tue followed by a pattern change with a stalled frontal boundary setting up over or near SNE, beginning Wed and continuing into next weekend. Lots of uncertainty on the exact placement of this boundary and timing and amplitude of frontal waves traversing this boundary. There will be periods of dry weather during this time as well, hence not raining every hour of the day.
AVIATION /12Z SUNDAY THROUGH THURSDAY/
Forecast Confidence Levels:
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
12z TAF Update...
Marginal MVFR/IFR will slowly lift to mainly MVFR but then likely lower this afternoon and especially late in the day as showers overspread the region from west to east. Light E-SE winds. Earlier discussion below.
---------------------------------------------------------------
Borderline IFR/MVFR ceilings between 008-012 feet with light easterly winds.
Sunday...High Confidence.
IFR/MVFR ceilings will trend to mainly MVFR thresholds with some diurnal heating despite the cloudy skies. Some showers will work into mainly interior MA & CT during the afternoon hours, but will not reach the coastal plain until late Sunday afternoon/evening. SE winds 5 to 10 knots.
Sunday night...Moderate Confidence.
IFR/LIFR ceilings develop with light showers spreading west to east across southern New England overnight. SE winds shift to more of a S direction at 5 to 10 knots.
Monday...
IFR ceilings lifting to VFR levels by late morning/early afternoon. Though lower IFR ceilings may persist longer over The Cape Islands. Light southwest winds becoming more westerly.
Winds may be weak enough to support a sea-breeze circulation along the coastline.
KBOS TAF...High confidence
KBDL TAF...High confidence
Outlook /Monday Night through Thursday/...
Monday Night through Tuesday: VFR.
Tuesday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA.

MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Today through Tomorrow
Seas increase by about a foot over the next 48 hours as winds become more steady out of the south. Nonetheless, conditions remain on the quiet side with wind speeds topping out at 10-15 knots and seas in the 2 to 4 foot range. A period of stronger gusts up to 20 knots is expected to develop tomorrow afternoon over the outer southeastern marine zones.
Outlook /Monday Night through Thursday/...
Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft.
Tuesday through Tuesday Night: Winds less than 25 kt.
Wednesday: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms.
Wednesday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers.
