A quick update on the timing of the showers and thunderstorms expected today:  Based on the HRRR and GFS LAMPS forecasts, the line of showers and thunderstorms moves into the immediate PHL area between 4 and 5 PM. (It moves through earlier in the far western suburbs.)

This morning’s models have downplayed the light quick showers that had been seen as a possibility around noontime.  Some scattered light showers may break out as early as 3-4 PM.

I hope my forecasts here have been useful.  I’m not sure why the radio and TV were still hyping this storm this morning.  Must be “alternate facts” syndrome.

Here are the snow storm totals from the NWS .

It looks like the “3, maybe 4” inch forecast will be about right, with it more likely just making 3 inches in Philadelphia and the immediate surrounding suburbs.  (Remaining QPF values according to the GFS is 0.18 inches water.)

I don’t know why the TV people kept pushing the 4-8 inches last night.  I think they had dug themselves into a “snow event” to raise their ratings as they often do.

Expect cold temperatures today and freezing of what fell. Sun angles are getting higher and melting with sunshine this afternoon is possible despite the cold air temperatures.
