PHILLY SNOWSTORM UPDATE – MON 10 PM EDITION

Here’s the latest on the snowstorm expected Wednesday. Tonight’s NAM data along with this afternoon’s model runs show high continuity suggesting that this is likely to be a high confidence forecast.

Latest NAM has a QPF of 1.34 inches water for PHL, higher amounts north and west of Philadelphia. (Expect those numbers to change with each model run.  It’s the nature of weather prediction.)

NAM Forecast Wednesday 1pm. A little less intense than this afternoon’s NAM

Still a significant snowstorm, with snow totals 12-18 inches as a current best guess.

Snow starts as a wet mix between 7-10 pm Tuesday night but changes to snow overnight. Snow falls moderate to heavy after daybreak Wednesday , tapering off about 6pm.

I’ll try to update tomorrow morning about 9:15 am.
