Philly Winter Weather Update - Sat PM
This afternoon's model runs underline the changeability and uncertainty of this type of stalled-front convergence precipitation event.
The models are now suggesting that the stalled front and the convergence zone will be further to our south. As a result, the amount of snow for Philadelphia looks to be much less than previously predicted. Currently, 4-6 inches looks like a better bet, with less further north.
Things may continue to change and uncertainty about snowfall amounts will continue. Stay tuned.

Philly Winter Weather Update - Sat AM
The models continue to predict a heavy snowfall for the Philadelphia area from late Sunday night through early afternoon Monday. Heaviest snow to fall during the morning hours of Monday. Still differences in the models with exact placement of the heaviest snow, but last night's GFS has the precipitation bullseye right over Philadelphia. Depending on the model, 6-8 inches of snow or 10-12 inches is what is currently expected.
As mentioned yesterday, this system is very different than past storms and uncertainties remain. Much of this storm's structure is really the result of a slowing frontal boundary being over-run by moisture, vs a compact low pressure system moving near us. This sort of scenario can result in forecast errors, since exact placement of the frontal boundary is difficult to forecast in advance with high precision. The predicted area of maximum convergence of cold and moisture may change. Stay tuned.
