Area Forecast Discussion National Weather Service Boston/Norton MA 252 AM EDT Wed May 1 2024

SYNOPSIS
Considerable cloudiness persists today, but peeks of sunshine are expected by early afternoon. Unsettled mid to late this week due to a backdoor cold front nearby. This could bring spotty showers and keep location to the east a bit cooler, but there is a significant amount of uncertainty with the fronts location. Better shot for more widespread showers late Saturday into Sunday as a frontal system slides through.

NEAR TERM /UNTIL 6 PM THIS EVENING/
3AM Update

Today

Scattered light showers just north of a weak surface low-pressure circulation continue to move across southern New England this evening. Based on the latest forecast guidance, we continue to expect this wave of low-pressure to be east of southern New England by the mid-morning hours. This will result in showers tapering off the east coast between about 06 and 09AM.

Northerly flow behind the departing low will aide in advecting cooler air from the north over over eastern MA for this afternoon.
Further west however, a mid-level ridge axis at 850 hPa will build eastward into western MA and CT with substantially warmer temperatures. Locations east of the ridge axis that experience prevailing north/northwesterly winds will be substantially cooler than those locations beneath the ridge axis where 925 hPa temps will be in the 10 to 13C range. As a result of this setup, we expect there to be a rather tight temperature gradient from west to east this afternoon. Generally expect the coolest locations to be east of the I-495 corridor and the warmest locations west of I-495 and especially in the CT River Valley. The area of greatest temperature uncertainty will be along I-495 where temperatures will depend on how far west the cooler air mass from the north/northeast is able to penetrate. Best guess is for high temps in the low to mid 50s along the immediate east coastline and upper 60s to low 70s in the CT River Valley. Central MA and RI will range from the upper 50s to upper 60s with temperatures gradually increasing from west to east.
Expect cloud cover for most of the areas across eastern MA and RI with some breaks of sun likely for locations west of Worcester beginning in the early afternoon hours. While it is likely to be a dry day for most there is a low chance for a pop up shower or two.

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

Tonight

Winds shift to the south overnight as weak surface high pressure builds east of southern New England. Generally expecting a quiet, cloudy, and seasonable night with lows in the mid to upper 40s.
Shower chances increase toward day break across eastern and northeastern MA as a short-wave trough originating from over Ontario digs south/southeast over southern New England.

Tomorrow

Somewhat of another tricky forecast tomorrow, particularly across eastern MA where some showers will be possible during the day. A broad upper-level ridge axis will be building in from the west with a warmer air mass tomorrow, but east of the ridge axis an embedded short-wave trough at 500 hPa will be digging southeast over southern New England. Vorticity advection east of the short-wave trough axis should provide enough forcing to support periods of rain across portions of New England tomorrow, but how far south these showers develop is still a challenge in the forecast. There is fair agreement in recent model guidance that the best forcing associated with this disturbance will stay to the north and east leaving most of southern New England dry. Eastern MA and The Cape/Islands will have greater chances for seeing some showers develop as the short- wave digs east over The Gulf of Maine this afternoon. Forcing and moisture are limited, so we have set PoPs between 20 and 40 percent for areas generally along and east of the I-95 corridor. High temps across eastern MA and The Cape/Islands will be cooler than the rest of southern New England thanks to the showers/cloud cover associated with the short-wave aloft, but interior MA is set to have a very warm day with highs getting into the low to mid 70s west of I-495.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/

Key Points:

* Overall quiet weather pattern ahead * Scattered showers late Saturday into Sunday * Warmup early next week

Fairly good agreement among models that upper ridge will build over New England Fri and most of Sat maintaining dry weather. Normally we would expect a significant warmup but in the lower levels, high pressure to the north of the region will maintain an onshore flow of cooler air, even into the interior (though it will be warmer there).

There are some timing differences with respect to arrival of showers in Sat-Sun timeframe. 00z GFS is most aggressive and is an outlier when compared to its ensembles as well as other medium range models.
Additionally, it maintains upper ridge over SNE through most of day Sat which by pattern recognition would keep any showers to our west.
It does appear that scattered showers will arrive late in the day but especially Sat night into Sun as upper ridge shifts offshore and cold front approaches from Great Lakes.

Beyond the weekend, looks dry with springtime warmth early next week as high pressure builds offshore and brings milder S/SW flow, though usual south-facing coastlines along South Coast, Cape Cod, and Islands will be kept cooler with onshore flow. Our next chances for showers looks to be Wed as closed upper low lifts into Great Lakes and next cold front approaches SNE.

AVIATION /07Z WEDNESDAY THROUGH SUNDAY/
Forecast Confidence Levels:

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

06Z TAF Update

Through 12Z...Moderate Confidence

-SHRA/-RA gradually tapers off from the terminals at and west of ORH by 07-08Z. MVFR/borderline IFR ceilings persist through 12Z across southern New England. Showers continue through about 10-11Z for the eastern terminals with a few stray showers possible thereafter. Light east/northeast winds.

Today...Moderate Confidence.

Any remaining showers depart the eastern terminals by 12-13Z. We should see cloud bases slowly lift into the early afternoon hours with VFR ceilings likely by 21Z or perhaps earlier. NE winds 5 to 10 knots.

Wednesday night...High Confidence.

MVFR/IFR conditions return overnight with a spot shower possible, but mainly dry weather expected. Easterly winds gradually become southeasterly and eventually southerly overnight with light speeds around 5 knots.

Tomorrow...High confidence in trends, moderate confidence in timing.

IFR/MVFR ceilings early will gradually lift to VFR levels by about noon time. Winds look to be steady out of the south/southwest for the first half of the day, but winds may shift counter-clockwise by later afternoon as a low-pressure circulation may be traversing over the region with a few showers.

KBOS TAF...Moderate Confidence in TAF. Showers should taper off from the terminal by 09-10Z but could possibly linger as late as 12-13Z.

KBDL TAF...Moderate Confidence in TAF.

Outlook /Thursday Night through Sunday/...

Thursday Night: Mainly VFR, with local IFR possible. Slight chance SHRA.

Friday: Mainly VFR, with local MVFR possible. Slight chance SHRA.

Friday Night: VFR. Chance SHRA.

Saturday: Mainly VFR, with local MVFR possible. Chance SHRA.

Saturday Night through Sunday: Mainly VFR, with local IFR possible. Chance SHRA.

MARINE
Forecaster Confidence Levels:

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

Today through Tomorrow

Low pressure moves east of the coastal waters today supporting northeast winds over the coastal waters for the first half of the day. As the day progresses, weak high pressure will build over the coastal waters leading to continued light/easterly flow across the marine zones. Overnight, winds shift to the south but remain modest around 5 to 10 knots. Winds increase out of the south/southwest tomorrow as an area of modest low-pressure moves over the coastal water. While winds will be stronger in the 10 to 12 knot range tomorrow, we don't anticipate conditions deteriorating enough to warrant SCY headlines. Seas will persistently be 2 feet or less through the end of the week.

Outlook /Thursday Night through Sunday/...

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

Friday Night: Winds less than 25 kt.

Saturday through Sunday: Winds less than 25 kt. Chance of rain showers.
