Philly Winter Weather Update -Fri 9 PM
The latest NAM model has snow starting between 7-8 AM. The QPF is still about 0.35 inches water. Ordinarily this would be 3-5 inches snow. One uncertainty is the temperature, which is forecast to rise above freezing, especially in NJ. As a result, accumulations would be reduced, possibly considerably. Another unknown is the rate of cyclogenesis off the coast. If strengthening occurs faster, the amount of precip could be greater. The confidence in this storm's snow forecast is lower than usual.

Philly Weekend Weather Weather - Fri PM
Fast moving disturbance along a frontal boundary will move to our south on Saturday, spawning a coastal low pressure system off the coast, giving us snow. The NAM model shows considerable strengthening far off the Jersey coastline, resulting in a fair amount of snow linger over us in the afternoon. Approximately 0.35 inches QPF (water equivalent fallling) translates into about 3-5 inches of snow for us. (Should development quicken, snowfall could be greater.) Snow starts in the morning, may mix with some sleet/rain briefly before changing back to snow, ending later afternoon. This warming may reduce accumulations.
Sat 12/29: Cloudy, snow develops in the morning and ends lae afternoon. Currently 3-5 inches expected, although there may be some melting on roadways, as temps may in the mid 30s.
Sun 12/30: Mostly sunny, windy and cold. High 36.
