Area Forecast Discussion National Weather Service Boston/Norton MA 120 AM EDT Wed Jul 9 2025
SYNOPSIS
This afternoon and evening brings scattered thunderstorms capable of producing damaging winds and flash flooding. Cooler weather expected Wednesday and beyond. Possible break from unsettled weather for the upcoming weekend.
NEAR TERM /UNTIL 6 AM THIS MORNING/
Key Messages...
* Strong to severe storms possible with heavy downpours and potential for flash flooding.
Already seeing several storms pop along the NY/CT state line as well as along the south coast sea breeze boundary. Expecting storms to continue to pop up through the afternoon and continue into the overnight period... though the area of greatest concern generally along and south of the MA Pike, some storms could form along the north coast. Orientation looks to generally be SW to NE, in line with nearly unidirectional SW flow in the low/mid levels suggesting potential for slow moving and training storms. With warm cloud depths near 14,000 ft suggesting efficient warm rain processes, storms that form will have the potential to drop an 1-2 inches of rain in an hour and cause localized flash flooding issues, especially in urban areas. A Flood Watch continues for the area thought to stand the greatest risk from mid afternoon through the first half of the overnight hours.
SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/
Key Messages...
* Isolated showers and thunderstorms possible but not a washout.
* Much cooler with highs in the 70s along the east coast and 80s elsewhere.
Cooler temperatures move in once the winds flip to easterly onshore flow. As such, the eastern coast of SNE should top out in the 70s while the hottest spot will be western/central MA, especially the CT valley where highs reach the mid 80s. Plenty of moisture sticking around with PWATs still 1.5+ inches, but a weakly forced environment so any showers will be scattered and difficult to nail down where exactly they'll materialize.
LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/
Key Messages...
* Periodic chances for showers through Friday before a break in the unsettled weather this weekend.
* Near to below average temperatures.
It is expected to remain quite humid through this weekend. Just thinking a brief cooldown Thursday, then the heat starts to build again into early next week.
Not much change to the overall synoptic pattern into Friday.
Still a risk for some showers and thunderstorms Thursday, and less of a risk Friday. It's likely Saturday is the day which features the lowest chance for showers. Even Sunday should be dry most of the time, with the risk for some showers and thunderstorms late in the day. Have low confidence in the forecast details early next week. Too much uncertainty with the timing of potential showers and thunderstorms.
AVIATION /05Z WEDNESDAY THROUGH SUNDAY/
Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Through 12z...Moderate confidence.
Ongoing TSRA is expected to wind down across eastern MA and RI between 06z-08z, few areas of -SHRA could linger towards 12z.
IFR ceilings spread from east to west as well, though do not think these ceilings go any further west than KORH. Wind shifts to the ENE 5 to 10 knots.
Today...Moderate confidence.
IFR cigs continue through most of the day from ORH east, MVFR/VFR west of ORH. NE winds 5-10 kts. Iso TSRA this afternoon across interior southern New England between 18z-00z.
