Low Shifts Westward Rain Saturday into Saturday Night Downpours Around Sunday
FLOOD WATCH POSTED FOR SE PENNSYLVANIA
Low pressure along the coastal Carolinas this afternoon continues to inch northward and the overall track of weather models since yesterday has been a westward shift. We talked yesterday about our area being on the western edge of the rain shield but with the more westerly track and low pressure heading up just inland into Delaware and the north of the Pennsylvania New Jersey border, It puts us at risk for at least a 1 to 2 inch rainfall beginning Saturday during the day and lasting into Saturday evening before low pressure and the rains shift northward.
In situations like this, forecasting rain amounts can be difficult and due to the convective nature of systems like this, somebody could easily wind up with double these amounts. There will be variability. The potential for some local flooding is there.
The NAM model and others bring the area of heavy rain over much of South Central and Southeastern Pennsylvania into Eastern Maryland. This is zone of 2 to 4 inches. In additions we have a rather wet humid pattern setting up for all of next week and there is the chance for downpours Sunday afternoon and every day next week. Saturday temperatures will be just into the 70s. Sunday through all of next week daytime highs will be in the 80s and nights in the low 70s. with high humidity.
