A National Weather Service map indicates that Massachusetts is bracing for heavy rainfall on Thursday morning, leading to a flood watch being issued across much of the state. Forecasters estimate that Eastern Massachusetts, Connecticut, and Rhode Island could receive up to 4 inches of rain.
Currently, a flash flood warning is in effect for parts of Eastern Massachusetts, including major cities like Boston, Brockton, and Quincy, with caution advised for drivers to avoid flooded roads. This warning is set to last until 9 a.m., while the broader flood watch will remain in effect until 4 p.m.
As the day progresses, the rain is expected to taper off in the afternoon, shifting from west to east, although it could linger until early evening across Cape Cod and the Islands. Additionally, isolated strong to severe storms may develop in Western Massachusetts and Connecticut.
Looking ahead, the weather is forecast to change significantly on Friday, with warmer temperatures and higher humidity returning as drier air begins to move in. Anticipated temperatures will rise into the 80s, with heat indices nearing 90. Afternoon thunderstorms are also a possibility.
This weekend, forecasters predict a more stable weather pattern as high-pressure systems settle in east of New England. Those in the eastern regions can expect slightly cooler temperatures, with highs in the 70s to low 80s, while interior areas may see highs in the mid to high 80s.
Currently, forecasters note no indication of severe thunderstorms, suggesting that any storms that do emerge should dissipate quickly. As early next week approaches, the heat will return with highs expected to rise into the mid to high 80s on Monday and potentially surpassing 90 degrees on Tuesday.
Overall, while the potential for heavy rain and flash flooding poses challenges, the subsequent shift to warmer weather and summertime thunderstorms could offer a balance in the week’s forecast, signifying a typical New England summer pattern.
