Area Forecast Discussion National Weather Service Boston/Norton MA 224 AM EDT Wed Apr 23 2025
SYNOPSIS
Warm and dry today followed by a chilly night driven by radiational cooling. Rather mild and dry conditions continue with high pressure over New England to round out the end of the work week, though there is a low chance of a passing shower late Thursday evening/night for northern Massachusetts, majority of the region is dry. A system for Saturday brings the next chance for widespread rainfall, though exact details remain uncertainty. Drier conditions return late this weekend into early next week.
NEAR TERM /THROUGH TONIGHT/
Key Messages...
* Seasonable day with lots of sun and light winds.
* Chillier night tonight outside of the urban centers.
Quiet, zonal flow in the mid levels today with high pressure building at the surface will allow for a seasonable and quiet weather day. Relatively light NW winds continue through the daytime hours, 5-10 mph. These will become calm overnight as good radiational cooling conditions allow the boundary layer to decouple.
So, light winds and clear skies will allow locations outside of the typical urban corridors to cool into the upper 30s and low 40s.
SHORT TERM /THURSDAY/
Short Term
Key Messages...
* Warmer on Thursday with quiet and dry weather, save for the chance of a spot shower in NW MA in the evening.
A broad mid level ridge overhead together with surface high pressure just offshore will prolong the quiet and dry weather through Thursday. The only exception is for western and central MA which may be in close enough proximity to a weak shortwave and moisture plume to our north to support widely scattered showers Thursday evening.
Temperature-wise, we will warm a few degrees on Thursday as warm advection in the low levels pushes 925 mb temps up a few degrees closer to 12C which would result in highs in the upper 60s and mid 70s, cooler along the south coast.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
Key Messages:
* Warm and mostly dry Friday, outside of a stray shower in northern Massachusetts Thursday evening/night.
* The next chance for widespread rain comes in Saturday, but there are uncertainties with the exact timing.
* Drier conditions Sunday into early next week.
The Big Picture: Nearly zonal flow at 500mb across the CONUS into Friday, a 850mb shortwave may produce a couple of spotty showers late Thursday evening into predawn Friday for those in far northern Massachusetts. Otherwise, dry on Friday with surface high pressure across New England. This feature moves northeast towards Nova Scotia ahead of the only soaking chance of rain for this part of the forecast, arriving Saturday. Behind the system, mid-level ridging, surface high pressure builds in from the northwest with drier conditions Sunday into Tuesday of next week.
Thursday Night to Friday Night: Weak shortwave rides the northern edge of the 850mb high, with the greatest forcing displaced to the north in northern New England. Cannot rule out a rouge shower for areas in northern Massachusetts, mainly along and north of Route 2.
Will have mild overnight lows in the 50s. Otherwise, dry conditions and increased cloud cover for Friday. Will be another warm day, as 850mb temperatures remain above normal +10C to +12C a quick look at BUFKIT and GFS and NAM show mixing Friday afternoon to 850mb. Highs Friday reach the mid-70s and for those in the CT River Valley may reach near 80F. At the coast it will be cooler do to the onshore wind/seabreeze given the time of year, and there the highs cooler in the low-60s, perhaps upper 50s for the Islands and outer Cape Cod.
Increasing clouds, becoming cloudy overnight ahead of the incoming system, will lead to a mild night in the 50s.
Saturday and Saturday Night: Broad northern stream mid-level trough moves across the northeast and development of a low-pressure system with a southerly LLJ. Will have anomolous PWATs advect into southern New England, 1.3" to 1.5", which is ~3 standard deviation above normal. There remains a uncertainty with respect to the exact timing of the onset and end time the rain, as mentioned previously, GFS is biased towards a more progressive outcome, continued to lean towards the slower solution which would bring rain in from west to east overnight with the steadiest through the day on Saturday, even rumbles of thunder cannot be ruled out with limited MUCAPE of a few hundred J/kg. A widespread soaking rain, modest probabilities for rainfall amounts greater than 0.5" across the region at 60 to 70 percent. Increase the potential rainfall to 1.0" or greater will have probabilites between 30 and 40 percent. WPC does have a low chance of excessive rainfall, placing all of southern New England under a marginal outlook. Will want to check back with us if you have outdoor plans for Saturday.
Sunday through Tuesday: Quiet weather to follow on Sunday, though it will be cooler, but features drying conditions as mid-level ridging and surface high pressure arrives. North-northeast flow Sunday lends to a cooler afternoon, highs in the upper-50s to low-60s. The flow becomes southwest Monday and Tuesday, bringing warmer temperatures in the upper-60s to low-70s on Monday, then low and middle 70s on Tuesday.
AVIATION /07Z WEDNESDAY THROUGH SUNDAY/
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
06Z TAF Update:
Through 12Z: High Confidence
Areas of LIFR fog Cape/Islands and around BOS will linger this evening until wind shift to NW clears it out 05-07z. Otherwise VFR. Wind becoming NW 5-10 kt.
Today: High Confidence
VFR. West/northwest winds around 10 knots. About a 50/50 chance for a sea-breeze at BOS, but likely would be after 18Z if it develops.
Tonight: High Confidence
VFR. Light and variable winds.
Thursday: High Confidence.
VFR. Winds light and variable, becoming southerly 5-10 kts in the afternoon.

MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Today through Thursday...
A cold front crosses the waters early this morning resulting in a wind shift to the northwest. This will also help usher out any remaining fog/low stratus over the south coastal waters. High pressure builds in from the west today and will support calm conditions over the coastal waters through at least Thursday.
Outlook /Thursday Night through Sunday/...
Thursday Night through Friday: Winds less than 25 kt.
Friday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers.
Saturday: Moderate risk for Small Craft Advisory winds with gusts up to 25 kt. Seas up to 5 ft. Rain showers likely, isolated thunderstorms.
Saturday Night: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
Sunday: Winds less than 25 kt. Areas of seas approaching 5 ft.
Slight chance of rain showers.
