MA Weather: Storms, Heat Today Cap Hottest July On Record

Three different weather outlooks and advisories have been called for Massachusetts ahead of volatile weather Wednesday. A heat advisory is in effect for temperatures in the 90s that could feel like triple digits as Boston caps its hottest July on record, while a hazardous weather outlook will accompany scattered thunderstorms across the region this afternoon in the evening. An air quality alert has been called for Western Mass.

The continued heat wave has people at risk for dehydration and heat stroke. Temperatures will be in the mid-90s, but it will feel even more stifling due to humidity. It's par for the course this July: Boston's average temperature entering Wednesday was 78.5 degrees this month, half a degree higher than the previous record. Wednesday is also the 12th 90-degree day in the city this month after zero such days in May or June.

Then come the storms. The National Weather Service said scattered thunderstorms will make their way between 3-8 p.m., intensifying in the early evening. Wind damage, power outages and some flooding in urban areas are possible.
