Philly Weather Update

As mentioned yesterday, the presence of a subtropical system will affect the models and the accuracy of the forecast this weekend.

The warm coastal trough/warm front that had been expected to move through last night  has been delayed and the models show it moving through later this afternoon.  Some brightening of skies during the early afternoon. The SE surface wind flow will keep some low cloudiness and haze/fog into this late afternoon.  The winds shift to the south about 5 PM, allowing more sun later in the day.

Sunday looks to be brighter with hazy sunshine, warmer and more humid.

A complex weather pattern with a cold front and associated low in the midwest interacting with the remnants of tropical storm Ana.  The models always have trouble with these systems, affecting the forecast.

The track of the remnants of tropical storm Ana will continue to affect the accuracy of this weekend’s forecast.  Some tropical models bring the system through our area Monday into Tuesday, but the majority of the models keep it, (and much needed rain) to our east.
