Monday and Tuesday are supposed to be hot, but just how hot?

The heat index, which is a measure of the temperature plus humidity, could top out in the triple digits on Monday, and close to it on Tuesday, the National Weather Service said.

Even without the humidity, just the high temperatures are supposed to be sweltering. The service noted that the area could break records over the next two days. At 1 a.m. Monday, it was still 81 degrees in Boston. By just before 11 a.m., the service reported it was 90 degrees at its Norton offices with a 73-degree dew point. Together, those make a heat index of 99 degrees.

With the potential for record heat, the City of Boston has declared a heat emergency, and various Boston Centers for Youth and Families are to be set up as cooling centers between 9 a.m. and 5 p.m. on both days.


Here’s what local meteorologists are saying about the potential record heat: 

Cindy Fitzgibbon, WCVB: ‘Heat Advisory today and tomorrow before the hot weather eases late week’

Josh Wurster, 7 News: ‘Hottest day of 2020 for many’

Matt Noyes, NBC 10 Boston and NECN: ‘Humidity actually has been much worse this year, but actual temperatures near 100° should break the Boston record of 98° set in 1882 for this date’

Terry Eliasen, WBZ: ‘Today should give us a new high for 2020 in Boston’

Jason Brewer, Boston 25: ‘Warm start, hot afternoon’

Zack Green, WBZ: ‘Heat like this gives more meaning to “Netflix and chill”‘
