Boston 25 Weather

Extreme heat this week

HEAT BUILDING THIS WEEK

Monday will be the most comfortable day of the week with highs in the 70s at the beaches at 80s inland. Humidity will be moderate with dew points in the lower 60s. Plan on mostly sunny skies.

TUESDAY STORMS

Tuesday turns hotter with highs near 90 in the Boston area. Strong and severe thunderstorms will develop in northern and western New England in the afternoon and drop into southern New England during the evening and night. Storms won’t be as strong after sunset, but could still deliver some brief heavy rain and strong gusts as they pass through. Daylight hours should stay dry locally.

DANGEROUS HEAT WEDNESDAY THROUGH FRIDAY

An Excessive Heat Watch is in effect Wednesday morning through Friday. This will be a dangerous stretch of extreme heat and humidity. Highs could exceed 100 degrees and the heat index (“feel like” temperature) could reach 110. Limit outdoor activity, have an AC plan, take lots of breaks, and stay hydrated. The days look generally dry and bright with the small chance for a lonely pop up on radar each day.

The overnights will be very uncomfortable with tropical humidity and lows in the 70s. That means you won’t get a reset overnight and the heat will tend to build upon itself each day.

4TH OF JULY WEEKEND

It is still early, but the latest forecast keeps the heat around this weekend with highs in the 90s. A nearby front may trigger scattered afternoon and evening thunderstorms, so be sure to check back as you consider your fireworks plans.
