Another HOT day expected in New England, and for many, it will be the third day of a heat wave with highs in the 90s.
Places like Burlington, Bridgeport and Manchester registered record-high temperatures yesterday and Boston was only one degree shy of the previous record.
A heat advisory remains in effect for most of New England through Tuesday evening. Heat index values are expected to reach the 100 degree mark once again in some towns, and in the 90s pretty much everywhere else.
Northern New England will be the exception, where highs will be in the 80s due to an increase in cloud cover and thunderstorm activity. A cold front will begin to move east from the Great Lakes, and with the high humidity, some of these storms could be strong.
The activity will be mostly over Northern New England, but we could also see storms approaching areas of central Massachusetts and Western Connecticut as the day progresses.
The main threat is for lightning, damaging wind and heavy downpours, especially during the afternoon.
The risk for storms will diminish as we lose daytime heating, but they will reignite on Wednesday as the front turns stationary. Widespread showers are expected.
A second front arrives Friday, bringing less humid air. There’s a chance for isolated showers Saturday into Sunday morning but we are not forecasting a washout by any means, so no need to cancel your outdoor activities.
Temperatures also cool down into the weekend, back into the low 80s. Humidity starts to build back into early next week, renewing our chance of afternoon thunderstorm development.
