Area Forecast Discussion National Weather Service Boston/Norton MA 307 PM EDT Tue May 13 2025
SYNOPSIS
Scattered showers and perhaps a few thunderstorms will be possible at times for the second half of this week...but not expecting a washout with the greatest risk for activity late Wednesday into early Thursday and possibly sometime Friday and/or Saturday. It will also become a bit more humid. The temperatures looks to turn cooler than normal by early next week.
NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/
Key Messages...
* Increasing mid/high cloudiness overnight with lows 45 to 55 * A few showers possible toward daybreak in our CT zones
Details...
Shortwave energy over the Tennessee Valley will lift into the Ohio Valley tonight. This will result in increasing mid-high level cloudiness from the west overnight
However
surface ridging to our east will exert enough of an influence to keep our weather mainly dry tonight. We may see a few showers develop toward daybreak in CT where enough warm advection aloft/forcing may result in the development of a few showers.
Overnight low temps should be in the 45 to 55 degree range across the region. The coolest readings will be the typical low-lying locations of north central/northeast MA...while the mildest readings will be found in northern CT where clouds arrive early along with a bit better low level moisture return.
SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/
Key Messages...
* Considerable cloudiness Wed but peeks of sun especially across eastern New England...highs mainly in the upper 60s/lower 70s
* A few showers possible Wed mainly across western MA/CT...but not expecting a washout
* Greater risk for a round of scattered showers and perhaps a few embedded t-storms will be Wed night
Details...
Wednesday...
Shortwave energy over the Ohio Valley will induce a modest southeast LLJ across the region on Wed. This will be battling the upper level ridging over the Atlantic nosing into eastern New England
So in a nutshell
we do expect a few amount of clouds on Wed but there may be peeks of sunshine especially across eastern New England closer to the mid level ridging.
Meanwhile...a few showers will be possible at times mainly across western MA and CT
However
not expecting a washout with many hours of dry weather is expected too. High temps on Wed will mainly be in the upper 60s to the lower 70s...perhaps a bit cooler along portions of the very immediate coast.
Wednesday night...
The mid level ridge axis will finally push further east Wed night as shortwave energy moves into the mid-Atlantic states.
The shortwave energy will be de-amplifying as it moves east...so that will limit the forcing associated with it. That being said...there is a decent signature for an elevated instability burst as Showalter Indices drop from above 10 to near or below zero within 12 hours
In fact
some of the guidance is indicated several hundred J/KG of elevated Cape.
Given the burst of elevated instability...we expect to see a round of scattered showers develop Wed night and there may be a few embedded t-storms as well if we end up with enough MUCape.
The increasing low level moisture will hold overnight low temps mainly in the middle to upper 50s. We may also see some patchy fog develop Wed night too.
LONG TERM /THURSDAY THROUGH TUESDAY/
Key Messages:
* Mild and unsettled conditions late this week and early part of the upcoming weekend. A low risk for thunderstorms Friday and Saturday.
* Temperatures trending cooler late weekend into early next week.
Continued agreement for unsettled weather to end the work week and into this weekend, but will be mild. Late this weekend into early next week will see temperatures turn slightly cooler than what is average for mid-May, along with continued shower chances.
Showers on Thursday morning give way to drying conditions with the shortwave exiting east and subsidence occurring in the wake. Cannot rule a spot showers across interior southern New England, though the overall trend is a drying one, albeit temporarily. Seasonable high temperatures, the upper-60s to low-70s.
Unsettled weather Friday and Saturday could come with the potential for a few severe storms, though exact details are uncertain. A cut off mid-level low ejects positioned over the northern Great Lakes ejects shortwave energy promoting showers and thunderstorms. At this time do not anticipate a widespread and day long soaking rain event.
The CWSU machine-learning probabilities highlight the region with a low probability between 5-15% for severe weather both days, and a slightly higher chance of severe weather for western Massachusetts and Connecticut, 15-30% on Friday. Still, the better odds of severe weather remains to the southwest across the Ohio River Valley for Friday and the Mid-Atlanitc for Saturday. Those with outdoor plans should monitor the forecast for any updates.
Sunday and Monday are transitional days, with drier air advecting in from the northwest as the mid-level low pushes east into the Gulf of Maine. Will have cooling trend falling from the 70s on Sunday into the 60s, albeit slightly lower than seasonable Monday and Tuesday.
Brief mid-level ridge and surface high pressure should trend to a drier Tuesday.
AVIATION /19Z TUESDAY THROUGH SUNDAY/
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
18z TAF Update...
This afternoon into tonight...High Confidence.
VFR conditions prevail most of this evening...but some MVFR conditions may develop across western MA/CT after midnight.
ESE winds of 5 to 15 knots this afternoon will become light/calm later tonight.
Wednesday...Moderate Confidence.
MVFR conditions should dominate across western MA/CT on Wed with a few showers possible at times...but not a washout.
Meanwhile...thinking a broken deck of VFR ceilings hang tough for much of the day across eastern MA/RI. ESE winds 5-10 knots.
Wednesday night...Moderate Confidence in TAF.
Widespread MVFR-IFR conditions overspread the rest of the region with the lowest conditions likely across the interior. We also expect a round of scattered showers to cross with region Wed night with perhaps even a few embedded t-storms. Light winds with an easterly component.
KBOS TAF...High Confidence in TAF.
KBDL TAF...High Confidence in TAF.
Outlook /Thursday through Sunday/...
Thursday: MVFR/IFR conditions possible. Chance SHRA, isolated TSRA.
Thursday Night: Mainly VFR, with areas IFR possible. Slight chance SHRA, isolated TSRA.
Friday: Mainly VFR, with local IFR possible. Chance SHRA, isolated TSRA.
Friday Night: VFR. Chance SHRA.
Saturday: Mainly VFR, with local MVFR possible. Chance SHRA, isolated TSRA.
MARINE
Forecaster Confidence Levels:
Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.
Tonight through Wednesday night...High Confidence.
Upper level ridging east of the waters will be enough to keep winds/seas below small craft thresholds tonight into most of the day on Wed
However
this upper level ridging slides further east Wed night allowing for winds to turn more SE and building swell
While winds will generally remain below SCA criteria
5 foot seas should develop across our southern outer-waters from the swell and will hoist small craft advisories for seas in this region.
Outlook /Thursday through Sunday/...
Thursday: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers, isolated thunderstorms.
Thursday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers, isolated thunderstorms.
Friday: Winds less than 25 kt. Seas locally approaching 5 ft.
Slight chance of rain showers, isolated thunderstorms.
Friday Night: Winds less than 25 kt. Chance of rain showers, isolated thunderstorms.
Saturday: Winds less than 25 kt. Chance of rain showers.
