Forecast calls for steamy Wednesday and Thursday, a break on Friday
Tomorrow marks the first official day of summer, and it’s going to feel like it. Today Boston will be in the mid-70s and mostly sunny. Temperatures will reach the low 80s in the western part of the state. But the mild weather is leaving with the spring. Intense heat and humidity will hit Massachusetts Wednesday and Thursday. Temperatures will be in the high 90s both days, National Weather Service meteorologist Bill Simpson said.
