Sunday Forecast Update

Update Sat 8/24 10:39 PM — A few models are showing widely scattered showers Sunday evening, dissipating just as they approach Philadelphia. The NAM-NEST and Canadian models have been consistent with this forecast, the HRRR, ECMWF and GFS show no showers. So just a possibility about 8 PM. Also, expect a fair amount of wildfire smoke haze in the afternoon.

NAEFS jet stream level winds (300 mb) forecast for Sunday shows our area under a cool flow associated with an upper trough, while the mid section of the country remains under a hot ridge.

Showers are not expected until late Monday, and not all models are on-board with that.
