More torrential downpours could again lead to flash flooding in Massachusetts

By Terry Eliasen, WBZ-TV Meteorologist, Executive Weather Producer

BOSTON - The WBZ Weather Team has issued a NEXT Weather Alert through Wednesday evening for the risk of scattered downpours and thunderstorms along with the possibility of some localized flooding.

The National Weather Service has also issued a flood watch through early Thursday for most of Southern New England.  

Just what we don't need: Another active day on the Doppler.

We are expecting multiple rounds of downpours/storms during the day Wednesday.

The first round comes late Wednesday morning and that will be followed up by additional downpours in the afternoon and evening.

There is the potential for a brief, spin up tornado, particularly with the morning batch of storms south of the Pike. Otherwise, the main concern today is for renewed flash flooding, especially in those areas that have recently been inundated with water.  

Unlike the storms on Monday that were nearly stationary, Wednesday's cells will be moving along. This should preclude any one area from getting anything close to the excessive rainfall amounts we experienced on Monday. However, there is a chance for a couple inches of water today in a short period of time. Given how high our water table is already, that would certainly be enough to cause another round of flash flooding.

The storm action will die down after sunset, leaving just a few showers across eastern Mass. overnight.

After a murky start at the coast on Thursday, the sunshine will emerge and, more importantly, the dewpoints will drop significantly.  Thursday will feel quite refreshing, a nice break from the soupy airmass that has hung over us for nearly a week now.

Friday will be another dry, comfy, coolish day, albeit with some increasing high clouds from the approaching Hurricane Lee.  More on that to come...
