Prior Forecast for Friday night…

The early NAM data has become available.  QPF values are 0.39 inches water.  Precipitation is just moving into the Philadelphia area now.

There are some changes– temperatures at critical levels in the atmosphere appear to remain too warm for snow in Philadelphia and the immediate suburban areas for much of this precipitation.

Areas far north and west (Doylestown and north and Pottstown and west) will have rain/sleet changing to snow about 2-3 AM.  A few hours of snow are possible before ending between 6 and 7 AM.  2  or so inches possible.

For the immediate suburbs of Philadelphia-  mostly rain or rain with some sleet….cold air does move in aloft towards the end the storm and there may be a transition to snow with some light accumulation before ending between 6 and 7 AM.   Nothing significant, as it’s March and anything that falls will melt soon enough tomorrow.

As we can see, the forecast can change for these borderline thermal profile events.

I’ll be checking the GFS later this evening when it becomes available.

There’s still uncertainty with the Sunday storm.  Stay tuned.
