Weather conditions across Southern New England are shifting dramatically after more than two weeks without measurable rain. Following an unusually warm Thursday, a slow-moving storm system is expected to bring periods of heavy rain, possible thunderstorms and a noticeable temperature drop through the weekend.
According to the latest WHDH weather report, temperatures reached the 70s across much of the region Thursday, levels more typical of August than early November. However, the most significant development was the end of the region’s prolonged dry streak as low pressure began taking control of the forecast.
Weather Pattern Finally Turns Wet Across the Region
A slow-moving cold front is already producing rain in parts of Southern New England. Scattered showers are expected to continue through Thursday evening, but the most substantial rainfall is forecast for Friday.
The heaviest precipitation is expected across southeastern Massachusetts, including the Cape, Islands, South Coast and South Shore. Rain will become steadier and heavier as the front moves through, creating the potential for ponding on roads, reduced visibility and localized flooding.
Between Thursday night and Saturday morning, some areas could receive more than 2 inches of rain. The rainfall will be especially important after the extended dry period, although the intensity and duration of the storm could create problems in low-lying areas and locations with poor drainage.
Critical Flood Watch Issued for Four Counties
A Flood Watch has been issued for Barnstable, Bristol, Dukes and Plymouth counties. The alert highlights the possibility of excessive rainfall and runoff, particularly in southeastern Massachusetts.
- Heavy rain is most likely Friday.
- More than 2 inches of rainfall is possible by Saturday morning.
- Barnstable, Bristol, Dukes and Plymouth counties are under a Flood Watch.
- Thunder could accompany the heaviest downpours.
- Drivers should watch for ponding water and flooded roadways.
Residents in the watch area should monitor changing conditions and allow extra travel time. Drivers are encouraged to avoid roads covered by water, since even shallow flooding can hide hazards and cause vehicles to lose control.
Warm Temperatures Collapse as Cooler Weekend Arrives
Friday will remain unusually mild despite the rain, with afternoon temperatures expected to reach the upper 60s and lower 70s. That warmth will not last. A sharp change arrives Saturday, when highs fall back to the mid-50s, close to seasonal averages for early November.
Lingering showers are possible early Saturday as the cold front exits. Another round of rain may develop Saturday night as an upper-level low keeps the atmosphere unsettled. Those showers could continue into Sunday morning before the system moves east.
The weekend outlook is therefore expected to be unsettled rather than stormy all day. Rainfall may come in waves, with breaks possible between showers. Even so, wet roads and low clouds could make outdoor plans more difficult, particularly near the coast and across southeastern Massachusetts.
Brighter but Breezy Conditions Return Monday
Conditions should improve Monday as the upper-level low pulls away. More sunshine is expected, but the day will remain breezy, with wind gusts reaching the 20s. Afternoon temperatures will stay cooler, topping out in the low 50s.
The early-week forecast marks a return to more seasonable conditions after the remarkable warmth of Thursday and Friday. The change will be noticeable for commuters, students and anyone planning outdoor activities across Boston and Southern New England.
For now, the primary concerns are heavy rain, localized flooding and rapidly changing temperatures. The shift from dry weather to a soggy stretch may also bring relief to areas that have gone without meaningful rainfall, but residents should remain alert during the heaviest downpours.
