Get ready for the heat. Forecast early next week is for the northeast to have the hottest temperatures compared to local normals/averages in North America. pic.twitter.com/OH23Hedo6T

Tomorrow is looking very warm to hot, but early next week is looking on the extreme side for heat. Boston hit 100 in 2022. pic.twitter.com/mOfg5890QX

Tucker Antico, Boston 25: ‘Very good chance that a few places in New England reach 100F next Tuesday’

I would say it’s more likely than not, that Boston’s 95F record high will be broken

Eric Fisher, WBZ: ‘Watching Thursday PM for a risk of severe thunderstorms’

Watching Thursday PM for a risk of severe thunderstorms.

Right now, timing looks to favor interior New England

Will have to see trends over the next 24 hours if they will make it into the Boston area. Least likely SE of the city. Will be talking about it more on #wbz pic.twitter.com/bdgZd21mgQ
