If you were hit by some thunderstorms yesterday, consider that your payment for some nicer weather today! A cold front moved through the Tri-State last night bringing much cooler and less humid air.

Under a northeasterly flow at the surface, highs will struggle to even hit the upper 70s today! We will see scattered cumulus clouds through the afternoon and clearing skies this evening. Expect lows to drop into the middle 50s and even lower 50s in outlying areas away from the city.

After a crisp start early Friday morning, the July sunshine will help warm us up into the 80s by late afternoon. Several thunderstorms complexes will be to our west through the afternoon hours. High pressure and relatively dry air at the surface should act to dissipate these as they move east Friday evening. However, an isolated storm or two cannot be ruled out after 6 p.m. as these clouds move in from the dissipating storms.

The heat and humidity will be back in full force this weekend. Unfortunately this means that chances for thunderstorms will increase as well. Thunderstorm activity is expected to only be scattered in nature on Saturday. Consequently, temperatures are expected to peak then as well. We will see highs push the lower 90s on Saturday afternoon.

Several forecast models are suggesting the development of a large thunderstorm complex Saturday night. These summertime storm complexes are extremely hard to predict, but do know the potential exists for thunderstorms with heavy rainfall Saturday night into Sunday morning.

A sharp trough (dip) in the jet stream will swing a strong cold front through on Sunday afternoon. This will bring a good bet for showers and thunderstorms during the day.

Much cooler air is forecast to return next week as a large upper low in the atmosphere settles over the Great Lakes and North East. This will mean highs back into the 70s and lows in the 50s which is pretty nice for late July!
