Good afternoon! After a chilly, overcast start with low clouds, a warm front was able to push through the area, which generated enough lift to mix out the marine layer — leading to increasing sunshine and warmer temperatures. For the most part, we got up into the 70s today for highs. This pleasant weather will last into the evening, before a strong cold front approaches the area, which could lead to some scattered showers and thunderstorms.
As we speak, a very strong line of showers and thunderstorms extends from West Virginia through Upstate NY and is making its way towards State College. These locations could have plenty of severe weather with damaging wind gusts and even a few isolated tornadoes. This is associated with a large closed 500mb low in the Great Lakes. The main forcing for these storms is this strong 500mb low and a potent jet streak just ahead of it, as well as a diffluence zone underneath this jet streak, all helping to promote lift for thunderstorms in a very warm and moist airmass.
