Snow Storm Fizzling for Philly- Thur AM
This morning's models now point to an unphased or late phased weaker storm in the Atlantic. Much of the snow will miss us and even miss NJ. Updates later.

How much snow for Philadelphia and when?-Thur AM
I'm away in the tropics, but I'm continuing to track the possibility of snow for Philadelphia.
The details of this potential storm continue to change. The time frame, initially Saturday, is now late Sunday into Sunday night. The track, as depicted by the GFS, is now similar to the ECMWF model with the storm forming near Fl and then moving north along the coast. The latest trend is the precipitation will affect NJ and the accumulation will taper significantly less further west of the Delaware river. This is captured by the operational GFS as well as the statistical ensemble GFS ( which has the snow a bit further westward.) What is disturbing is that the latest NOGAPS model continues its forecast of keeping the energy unphased, resulting in virtually no coastal storm development at all. The same is true of the DGEX model. I have never seen a storm where the NOGAPS isn't onboard.
So despite the agreement of the GFS and ECMWF, this snowstorm is still uncertain for PHL. Stay tuned.
