Damp End To Friday

We're starting off the day on a mix of clear and cloud note but it won't end that way as a storm system approaches and a warm front lifts northeast through the region later on today.  This disturbance is still back in Missouri, with a warm front pushing east into Kentucky as of 4 AM.  However, the fast-moving pattern that we've been a part of will push moisture towards the region at a rapid rate and we could see showers move into Central Pennsylvania southeast into Delaware by 4 or 5 PM this afternoon in advance of a warm front that will cross the region this evening.  Precipitation will generally lift to the northeast.

Showers could be steady to perhaps even heavy this evening and some rumbles of thunder are definitely possible as the warm front lifts into the region.  Rainfall totals may end up being a bit heavier north and west of Philadelphia compared to south of town with the evening batches of rain as they move through, but most locations should end up with less than an inch of rain by the time this is all done.  Stronger thunderstorms are still possible in Western Pennsylvania southwest into the Ohio Valley, with the potential for severe weather west of State College and across much of the Ohio Valley later today and tonight.

Before then, expect an increase in cloud cover as the morning progresses thanks to clouds moving in off the ocean and out ahead of this afternoon's shower activity.  High temperatures during the day will probably occur in the early afternoon, generally in the lower and middle 50's in many locations.   With the showers pushing northeast this evening and overnight, temperatures may drop back as rain begins only to rise as the warm front pushes through overnight.  Temperatures may be close to 60 degrees by tomorrow morning in Philly and points south.
