BOSTON - Welcome to a NEXT Weather Alert Day!

We are expecting two distinct rounds of storms and downpours Tuesday in two very different locations.

Round 1:

The strongest storms over southeastern Massachusetts, including the Cape and Islands. Expecting areas of heavy downpours, pockets of street flooding and some lightning. While the chances remain low, we cannot completely rule out a quick spin-up tornado or water spout in that area. Main timeframe for round 1 is between 9 a.m. and 1 p.m.

Round 2:

After a relative lull for much of the afternoon, we will be tracking a broken line of storms coming out of New York state later Tuesday. The highest risk of an additional downpour or severe storm would be over western and central Mass. By the time the line reaches eastern Mass., it is likely to have lost most of its' steam. Main timeframe for round 2 is between 5 and 9 p.m.

BIG improvements are on the way for Wednesday! 

The sunshine returns along with high temperatures near 80 degrees. The humidity will be much lower as well. Wednesday will be rather windy with sustained winds between 10 and 20 mph and some gusts 20-to-30 mph out of the west-northwest.

Thursday and Friday will be our first true taste of Fall! 

High temperatures will be near 70 but the air will be quite dry and crisp. Night time lows will drop into the 40s in many suburbs.

The weekend will likely stay dry and pleasant with a warming trend by Sunday and Monday. There will be a frontal boundary somewhere in the area though. If it stays to our north, which appears to be the most likely scenario, we stay dry in southern New England with warming temps. If it dips south, that could mean a few showers later in the weekend and cooler temperatures. 

Certainly something to keep an eye on if you've got weekend plans!

Lastly, the Patriots are playing in Pittsburgh on Sunday. It looks quite warm down there, no major weather concerns for the game.
