Area Forecast Discussion National Weather Service Boston/Norton MA 111 AM EDT Mon May 6 2024

SYNOPSIS
A period of widespread showers impacts the region tonight with the focus for them this evening. Partial sunshine develops on Monday with much warmer temperatures. A brief band of scattered showers is expected Monday afternoon/evening...but the majority of the time will feature dry weather. Tuesday will be the pick of the week with abundant sunshine and above normal temperatures. Unsettled pattern develops for Wednesday and beyond with below normal temperatures. Some uncertainty revolves around the weekend forecast.

NEAR TERM /UNTIL 6 AM THIS MORNING/

1AM Update

Showers traversing across southern New England this evening are moving a bit faster than expected and will be coming to an end for hte areas across northeastern MA in the next hour or two.
Showers persist for a few more hours over the south coast, southeastern MA, and RI before clearing out this morning. Made some updates to reflect the faster departure of showers. The rest of tonight's forecast remains unchanged. Expect some patchy areas of fog to develop with light winds and plenty of moisture in place prior to sunrise.

Previous Update...

335 PM Update...

* Period of widespread showers tonight with the focus this evening * Low temps between 45 and 50 with areas of fog developing

Approaching shortwave/mid level warm front was inducing a modest southwest low level jet this afternoon. This has allowed a band of widespread showers to overspread areas northwest of I-95. This band of showers will gradually sink southeast and impact the Boston to Providence corridor by late afternoon/early evening. Once the steady showers arrive they should generally last between 3 and 6 hours. The bulk of the showers will come to an end northwest of I-95 near or shortly after midnight...but linger towards the Cape and Islands.

Overnight low temps should only drop a few degrees from their current readings...mainly in the 45 to 50 degree range. We do expect some fog to develop overnight given increasing low level moisture with light southerly flow.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM TUESDAY/
Key Points...

* Partial sunshine developing away from south coast Monday * Turning much warmer with highs well into the 70s for most on Monday * Scattered brief showers Mon PM, but most of the time it will be dry

Details...

Monday and Monday night...

Any lingering showers towards the Cape/Islands should come to an end Monday morning as the shortwave departs. Subsidence and enough westerly flow aloft should allow for partial sunshine to develop.
Temperatures will quickly respond give 850T near +10C. It will be much warmer than today with highs well up into the 70s. May even feel a tad humid given dewpoints in the upper 50s to near 60...so quite the change. It will be cooler near the south coast, Cape and Islands where low clouds and fog patches may linger.

The vast majority of Monday will feature dry weather
However
a cold front dropping south will probably result in a band of brief scattered showers dropping south Monday afternoon and evening. There probably will be a few hundred J/KG of Cape developing...but mid level dry air advecting in from the west will limit potential. So while a rumble or two of thunder is possible...opted to keep out of the forecast for now. Later shifts may have to take another look.
Low temps Monday night will mainly be in the upper 40s to the middle 50s. There may be some patchy fog development too.

LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/
* Dry and Mild on Tuesday

* Persistent period of cool temps and heightened rain chances Wednesday through early next week.

Tuesday continues to be the pick of the week, and while heights begin to fall as more zonal flow develops aloft, west/northwest downsloping boundary layer flow will support well above normal temps with 850mb temps between 7 and 9C and 925mb temps around 13C. Weak pressure gradient will lead to a seabreeze along the immediate coastline, so while temperatures soar into the mid and upper 70s across the interior, coastal localities will likely see peak temps in the late morning before temps drop back into the upper 50s/low 60s by late afternoon.

Synoptic shift towards a more zonal pattern on Wednesday and Thursday with a few shortwaves enhancing shower chances across southern New England. Robust trough develops over the eastern CONUS by Friday, allowing very unsettled pattern to persist through much of the weekend as low pressure remains nearly stationary over southern Ontario. Fortunately, the weak shortwaves wont bring tremendous rain chances to the region, with 7 Day QPF ensemble probabilities of 1" ranging between 40, SE MA, and 80, NW MA, percent through next Monday. While still a week out, the persistence of the pattern into late next weekend is a bit uncertain, with some global guidance, like the CMC and GFS, shifting the trough offshore late Saturday/early Sunday, which could yield improving conditions for the second half of the weekend.

Aside from scattered rain chances later this week, temperatures will be stuck below to well below normal thanks to aforementioned stalled front and very persistent onshore flow. Temps will be stuck in the 50s most days across the eastern half of the CWA Frontal boundary placement will make temperature forecasting a bit tricky for CT and western MA, where there are few opportunities late week for temps to climb into the 60s in that region.

AVIATION /05Z MONDAY THROUGH FRIDAY/
Forecast Confidence Levels:

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

06Z TAF Update

Through 12Z...High Confidence

MVFR/IFR conditions persist through 12Z with patchy areas of fog developing. -SHRA continues over The Cape/Islands with light southeasterly winds.

Today...Moderate Confidence

MVFR/IFR conditions early should scatter out to VFR by 12-14Z across the interior and at BOS. MVFR/IFR conditions persist over the south coast, Cape, and Islands. Winds light out of the west/southwest. Sea-breeze developing at BOS by mid to late morning.

Tonight...High Confidence

MVFR/IFR conditions fill back in across the interior and persist over the south coast, Cape, and Islands through about 06Z. Winds shift to the north after that time frame and allow ceilings to gradually improve to VFR by 09-12Z.

Tomorrow...High Confidence

VFR. Light northerly winds becoming light out of the west. Sea- breezes likely along the coast with very warm temps forecast over land.

KBOS TAF...Moderate Confidence in TAF. BOS should scatter out for a few hours this morning into early afternoon before returning to MVFR by early to mid afternoon. Moderate confidence in a sea- breeze circulation developing today between 14 and 16Z. Higher confidence in a sea- breeze for Tuesday.

KBDL TAF...High Confidence in TAF.

Outlook /Tuesday Night through Friday/...

Tuesday: VFR. Slight chance SHRA.

Tuesday Night: Mainly VFR, with local MVFR possible. Chance SHRA.

Wednesday: Mainly MVFR, with areas IFR possible. Breezy. SHRA likely, isolated TSRA.

Wednesday Night: Mainly VFR, with local IFR possible. Breezy.
Chance SHRA.

Thursday: Mainly VFR, with areas MVFR possible. Breezy. Chance SHRA, isolated TSRA.

Thursday Night: MVFR/IFR conditions possible. Breezy. SHRA likely, isolated TSRA.

Friday: MVFR/IFR conditions possible. Breezy. Chance SHRA.

MARINE
Forecaster Confidence Levels:

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

Tonight through Monday night...High Confidence.

A mid level warm front will cross the region tonight this will be followed by the passage of a weak cold front Monday night.
However...the pressure gradient will remain relatively weak...keeping winds/seas below small craft advisory thresholds. We may have enough of a LLJ for some southerly wind gusts of around 20+ knots to develop very late tonight into Monday morning. Winds gradually shift to more of a W direction Monday afternoon and then NW Monday night...but well below small craft advisory thresholds.
The main issue for mariners will be areas of fog developing overnight and persisting at times through Monday evening...until the cold frontal passage brings drier air and scours out the remaining fog.

Outlook /Tuesday Night through Friday/...

Tuesday: Winds less than 25 kt. Slight chance of rain showers.

Tuesday Night: Winds less than 25 kt. Chance of rain showers.

Wednesday: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms.

Wednesday Night: Winds less than 25 kt. Seas locally approaching 5 ft. Chance of rain showers.

Thursday: Winds less than 25 kt. Seas locally approaching 5 ft.
Chance of rain showers, isolated thunderstorms.

Thursday Night: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers, isolated thunderstorms.

Friday: Winds less than 25 kt. Seas up to 5 ft. Chance of rain showers.
