Foreshadowing of Summer

The region this morning is waking up to a warm and muggy conditions, with temperatures near 70 in the city and in the mid/upper 60's in many of the surrounding burbs. Like yesterday, we should make another run at 90 degrees this afternoon and the combination of heat and humidity will make it feel a few degrees warmer.   For those heading out to start Memorial Day weekend activities at the Shore or your favorite vacation spot, it will feel quite a lot like summer here in the Delaware Valley today.

Yesterday's severe weather events in Central and Northeastern Pennsylvania were pretty rare in terms of hail size (three inch hail is teacup size, just a bit larger than baseball) for this part of the country.   The dynamics that drove yesterday's hail and wind events in Central Pennsylvania aren't quite as robust today as they were yesterday but you have enough ingredients in the severe weather pot (frontal boundary, lift, warmth, and moisture) to produce more scattered strong and severe thunderstorms this afternoon across western and northern sections of the region.

A slight risk for severe weather is out for areas to our north and west -- much like yesterday in coverage area -- and thunderstorms today should generally be more numerous to the north and west of the city than the south and east.  The strongest of storms could bring wind and hail that are severe criteria, with thunderstorms developing after 2 PM and generally tracking northeast.
