Massachusetts Weather Forecast: Heavy, Slow-Moving Downpours On Horizon

Slow-moving downpours and flash flooding are heading toward Massachusetts for a mid-week soaking, forecasters said Sunday. Labor Day and your beautiful Tuesday will be largely unspoiled, but Tuesday night and especially Wednesday and Thursday are set to receive some very heavy rains.

There is no precise timeline yet, but the rains will begin to move over Western Mass. some time Tuesday night. They will persist overnight, slowly moving farther east into Wednesday, and lingering for a couple of days. It might not be clear again until late Saturday.

"With periods of heavy rain falling over the same areas for a couple of days, there will be some flooding of roads and poor drainage areas. Flooding of small streams and creeks is also not out of the question," AccuWeather Meteorologist Brian Thompson said.

Western Massachusetts will be pounded by rain Tuesday night, and the wet weather will move east throughout Wednesday. The main threats are lingering downpours and flash flooding. Roads could flood and visibility will be limited, making traveling risky business.

If you are heading to the Patriots' NFL season opener on Thursday night in Foxborough, bring an umbrella. We should be right in the midst of the wet stuff.

"As the front slows to a crawl as it approaches the East Coast, it will lead to frequent showers and thunderstorms along the I-95 corridor from Tuesday night through Wednesday," Thompson said.
