Reading Mt. Holly's forecast discussion it would seem that the potential for heavy rain exists, but isn't a certainty. What seems certain is that there will be occasional showers and possibly a thunderstorm through early tomorrow morning with some clearing as we move through the day. The yellow lot could get a little sticky in spots, but there's plenty of high ground out there that should be okay.
Yep, that's largely been the forecast for a couple of days and every model now confirms it, so we're getting a bit of a break on the timing. The heavy showers should be over by 5-6 am and then there could be some lighter, more scattered showers until maybe 10-11 am at the latest, although some models show them over by 8-9 am. And no showers on the back end until at least early Sunday morning.
Should end up being a great afternoon for tailgating and the game with warm temps (low 70s) and mixed clouds and sun, with light winds. With an inch or more of rain overnight, though, there will certainly be some wet spots, but nothing people can't maneuver around. See y'all at the game. @mildone?

SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
Weak front oriented SW to NE will be draped across eastern PA to
start the day with ongoing showers ahead of it along and S/E of
the I-95 corridor. Some of these may continue to be heavy. The
good news is showers and any left over storms will taper off
through the morning from west to east with the passage of
shortwave energy aloft. Beyond this time weak ridging aloft will
temporarily move in for the afternoon with some mid level
drying also occuring. For this reason expect threat for showers
to continue diminishing in the afternoon with any activity
being isolated over the southern Delmarva. Otherwise, some sun
develops with most areas once again seeing highs in the 70s as
front dissipates over the area. &&
