SPRINGFIELD, Mass. (WGGB/WSHM) - A First Alert Weather Day has been issued for Sunday across western Mass for extreme and dangerous heat. There is also a risk for isolated strong to severe storms tomorrow evening.

It took some time for the clouds to clear out today so temperatures were held down a bit this afternoon but we still managed to make it to 90° this afternoon at Westover in Chicopee. That’s our first 90° day of 2022 and tomorrow looks to be even warmer.

Muggy and mild tonight with lows in the 60s to even near 70-like a mid-summer night! No relief Sunday as it will begin with a few clouds that give way to sunshine quickly. Temperatures soar and return to the lower and middle 90s with a heat index nearing 100 in spots. We will need to watch for pop-up, isolated thunderstorms Sunday afternoon and evening ahead of a cold front. Any storms that develop may become severe with hail and damaging wind gusts. The front arrives closer to midnight with showers and will usher in less humid, cooler air for Monday.

Seasonable air returns early next week with highs in the 70s Monday to Wednesday and much lower humidity. A developing onshore flow will keep patchy clouds around early in the week, but our weather looks rain-free. Later in the week, our next weather maker will approach with increasing chances for showers and storms along with warmer temps and higher humidity.
