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.
