Don’t let the early sunshine fool you today. Rain is on the way.
Trying to pin down the onset of rain in PHL —. The NAM and the NAM-based HRRR has scattered shower activity as early as noon with more organized rain by 2PM and heavy rain by about 5 PM. The GFS is a bit slower with the rain, starting about 2-3 PM and heavy about 5-6 PM.
