BOSTON (CBS) – We have another round of heat and very high humidity and that will be followed by some potentially severe thunderstorms on Tuesday afternoon and evening.

Our WBZ-TV weather team has declared this a Storm Watch Weather Alert day in response to a strong cold front which will be moving through the area late in the day.  A severe thunderstorm watch has been issued through 7 p.m.

During the afternoon, clouds will begin to build and a line of heavy downpours/thunderstorms will approach from the west-northwest.

Arrival in Worcester County will be between 1 and 3 p.m. and in eastern Massachusetts and Boston between 3 and 6 p.m.

The main impact from these storms will be very heavy, torrential downpours, potentially causing some localized flash flooding.  Some areas could receive a quick 1-to-2 inches of rainfall.

In addition, there may be some vivid lightning and damaging, straight-line wind gusts within any of these storms.

The tornado risk is low, but cannot be ruled out.  The main storm threat is for areas north and west of Boston, most of the storms should rapidly deteriorate as they reach the South Shore.

Tuesday is the lone “threat” day this week.  The rest of the week will be warm but dry with much more comfortable air moving in behind the front.
