Plenty of percipitation over nigth. The link above to the Harrisburg USGS percipitation gauge measured a little over an inch of rain between 7pm(Sat-26th) and midnight.
Trails will likely be wet with some running water in the usual places. Trails were in near perfect conditions before the rain, dry and fast with lots of leaf cover. With an inch or more of rain over just a few hours watch for washed areas and possible newly downed trees, although this storm didn't bring the really high winds that usually blow trees over.
