Monday Insights:
Midweek Transition to Heat, Humidity & Thunder

The long-anticipated shift into a summer weather pattern is underway across New England. After scattered showers and clouds start the week – particularly Tuesday and possibly Wednesday with a passing warm front – Thursday delivers our first truly hot, humid day of the season. Highs climb to 90°F or higher in many areas and dew points near 70°F will make it feel even hotter.

This heat and humidity could fuel strong to severe thunderstorms Thursday afternoon and evening, especially in northern and western New England, with timing into eastern zones depending on how fast the cold front advances.

Friday brings another impulse that could generate scattered showers or a storm, but the air is changing again – less humid and more comfortable. Rain totals through the week stay modest (0.25–0.50″), and by the weekend, it’s looking like classic summer.

And great news for anyone heading to the Acton Carnival (Route 2 corridor)—the forecast is nearly perfect from Thursday through Sunday. Whether you’re soaking up the heat Thursday, enjoying the comfort of Friday/Saturday, or enjoying the summer feel on Sunday, it’s a winning forecast.
