We may only be two months into the baseball season, but some residents of the Northeast and New England might be thinking it feels more like football season by midweek.
No, the Bills and Patriots won't be kicking off on Sunday, but highs could get stuck in the 50s Wednesday and Thursday across portions of Upstate New York into New England.
A few localized strong to severe thunderstorms swept across portions of central and eastern New York into New England Tuesday afternoon. Hail covered the ground in places like Utica, New York, making it look more like winter than spring.

Tuesday's storms were associated with a cold front, or leading edge to cooler air, which helps sets the stage at for the midweek cooldown.

Wednesday's Upper-Level Pattern

A trough of low pressure aloft, or southward dip in the jet stream, will set up over the Northeast for Wednesday and Thursday. Underneath the trough will be chilly temperatures for early June.
As close as a mile above the ground, air temperatures will cool to the freezing mark over northern New York and northern New England. Due to such cold air so close to the surface, the strong June sun will struggle to push temperatures out of the 50s midweek.

Wednesday's 850 mb Temperatures

For some, this cooldown will feel refreshing after the recent warmth and humidity. For others who want it to stay warm, fortunately, the cooldown will be short-lived, as temperatures begin to warm again by Friday and Saturday.

Forecast Highs

Nights will be quite chilly, too, with morning lows falling into the 40s for some locations on Thursday and Friday. Yes, you may need that light jacket as you head out to work.

Severe Weather Threat

The threat of severe weather returns to the Midwest on Friday and the Northeast by Saturday, as strong disturbances ride down the east side of a high pressure ridge that will be parked over the Midwest.
These are called "northwest flow" thunderstorms and are capable of producing damaging winds and large hail. The risk of tornadoes appears to be low, but an isolated tornado or two can occur in these situations.
