Tracking Tonight's Rainfall
By tomorrow morning, the frontal boundary will be approaching the region and steadier rains will be about to depart. The NAM, below, shows a lingering line of rain and thunder through the region around 7 AM. The NAM suggests rains will push off the coast by 10 or 11 AM tomorrow, with the GFS slowing the end of the rain into early afternoon (the GFS is the slowest on having the rains exit stage right). In any case, the morning will feature a bit more rainfall than after midday and in fact some sunshine is certainly possible after midday tomorrow across the region from Philly on west in the latter afternoon hours in Jersey.
The Storm Prediction Center still highlights the potential for severe weather across Western Pennsylvania later on tonight and a severe thunderstorm watch is certainly possible out near Pittsburgh later on tonight as the line of thunderstorms and wind-whipped rain in Ohio works east.
