Weather Alert: Heavy Rainfall Expected Wednesday

MIDWEEK WEATHER ALERT

Following the rainy afternoon across the interior, a few lingering showers and thunderstorms will be possible overnight in these same areas. The Greater Boston Metro area will see a gloomy and humid night, yet rain chances really don’t pick up until after sunrise tomorrow.

Tomorrow’s late morning commute might be a bit messy with showers and thunderstorms causing some problems on the roads, especially for areas south of the Mass Pike. Heavy rain bands will pivot northward for the afternoon and evening into Northern Massachusetts, while southern areas may see more of a reprieve.

Average rainfall 1-3″ is expected, but localized totals could be 5″+. We have a lot of moisture to work with and the steady rain will be torrential at times. Street and city flooding is likely in areas, especially out west towards the Worcester hills with Tuesday’s rainfall factored into the flood threat. The worst of the weather is currently expected in the afternoon, though you’ll want a raincoat all day.

LINGERING SHOWERS

Low pressure will be very slow to pull away. The result is more cloudy, humid, and cool weather Thursday and Friday with some lingering rainfall. There could be some embedded downpours on Thursday, but rainfall looks more on the order of 0.25-0.5″. By Friday we’re expecting 0.1″ or less with late day improvements. The trends are good heading into the weekend with lowering rain chances and highs heading back into the 80s!
