Weather Alert: Heat, humidity, thunderstorms

HEAT, HUMIDITY & THUNDERSTORMS

We’re on a Weather Alert for peak heat and humidity today and Friday. It is the first time this summer we’ve had widespread dew points reach or eclipse 70 degrees, which translates to tropical feeling humidity.

Much of the rest of today will be dry and partly sunny. A Heat Advisory was expanded for our hot spots away from the coast where the “feels-like” temp will range from 95-100 degrees both these next two afternoons. Plan on highs in the low to mid 90s inland, and 80s at the local beaches. An Air Quality Alert is in effect in southeastern MA.

We also have the risk for an isolated strong or severe thunderstorm in the afternoon/evening both days. Today the threat runs from 4-10 PM. Most areas will stay dry, but you should be aware in the case a 30-minute burst of rain impacts your location. Friday afternoon watch for a pop up thunderstorm on the sea breeze front that sets up in eastern MA, but the better chance for a strong storm will be further out west along a cold front late day.

WEEKEND CHANGES

The trailing cold front may lead to some overnight showers and rumbles Friday night into Saturday. Humidity will drop significantly this weekend post frontal passage, but it will remain hot with highs in the 80s and lower 90s. Daytime outdoor plans are safe, but rain is expected Sunday night along a cold front, which will knock temperatures down slightly next week.
