Tonight's Storms Primer

A warm afternoon across the Delaware Valley will give way to a rather warm night -- with temperatures hard pressed to drop below 60 in many locations overnight as increasing clouds and gusty winds from the south help maintain warmth through the Delaware Valley.   Radar is showing a couple of bands of thunderstorms across Pennsylvania -- generally across Northern and Western Pennsylvania -- ahead of the cold front that is still back in Ohio.  Those thunderstorms...and the ones along the front...are moving northeast and it will take much of the night for the storms to reach the Philadelphia region.

Radar simulation from the Storm Prediction Center is suggesting storms should not reach the Philadelphia region until the early morning -- generally after 2 AM in Berks and the Lehigh Valley, after 4 AM in the Philadelphia region.   Thunderstorms will bring gusty winds with them -- perhaps to over 50 mph in the strongest of storms and a few severe warnings can't be ruled out late tonight or early tomorrow morning.

Storms will move through until midday -- ending from west to east.   The warmth that will last through the night will end quickly tomorrow morning with the frontal boundary crossing the region.   Temperatures will drop from the lower 60's to perhaps the middle and upper 40's before temperatures rebound somewhat in the afternoon hours as the sun tries to return.    Our "Spring Fling" will be short lived...and end with a rumbling.
