Probably some subsidence, but the dewpoints have crept up from the Catoctin Mts. east, so it's possible the front may be drifting west. If so, this puts I-95 in the game for at least a few hours of rain overnight.
You can tell even the sandy soil of the eastern shore is pancaked. The Ridgely mesonet site recorded over half an inch of rain in under 30 minutes, but the soil moisture values are just flat. It's going to take some time for moisture uptake to occur it seems.
