A heat advisory is in effect in Central Massachusetts through Thursday with temperatures expected to top 95 degrees this week, according to the National Weather Service.
“Hot and humid weather is expected through Thursday and perhaps even into Friday,” the weather service said in a forecast advisory Tuesday morning. “Heat index values look to exceed 95F several days this week and a Heat Advisory is in effect across the Connecticut River Valley through Thursday.”
It will remain humid over the weekend, with cooler “and less humid weather” expected next week, forecasters said.
“Hot and humid weather is in store for the region today, Wednesday and Thursday away from the immediate coast,” the weather service posted on X shortly after 5 a.m. “Heat Indices will reach well into the 90s each afternoon and peak on Thursday in the middle to upper 90s in many locations.”
In Boston, the high on Tuesday will be near 88 degrees, with a low of 71 overnight. Wednesday will be about the same, with the temperature rising into the low 90s on Thursday. Friday will be mostly sunny with a high near 90 degrees.
The extreme heat comes as many Massachusetts children return to school, many in buildings that do not have air conditioning and can get as hot as 90 degrees.
