Overview
- Across the region Monday, temperatures jump into the 60s under a gusty southwest wind, then surge to the upper 70s to near 80 on Tuesday.
- The Storm Prediction Center flags a marginal to slight severe risk from late Tuesday into Wednesday in parts of the Great Lakes and Ohio Valley, with threats that include damaging wind, large hail, heavy rain and a low tornado chance.
- A strong cold front expected Wednesday will flip the pattern, bringing showers and thunderstorms followed by a sharp cooldown into the 40s and 50s late week.
- Forecast confidence hinges on when the front arrives because an earlier passage would cap highs and limit storm intensity while a later one would allow more heating and stronger storms.
- Northern New England and higher terrain may see brief wintry mix or mountain snow after the front as many lower-elevation areas settle into a wetter, unsettled stretch into the weekend.
