What are feelings about the storm currently. Any chance of a write up?
Expect something along those lines tomorrow evening...for now suffice to say that PHL is looking at more of a snow/mixed precipitation situation with the possibility for significant accumulations as compared to rain/mixed precipitation. Right now the heaviest accumulations IMO should be northwest of the major cities (due in part to the location of the H85 low and the marine influences).
strong easterly LLJ at 35 to 45 kt on this past run of the ETA would provide sufficient moisture for heavy snowfall accumulations...however based on ETA-BUFKIT soundings I dont see favorable thermal profiles to support an all or mostly all snow event in PHL or DCA...NYC and BOX are another story. The LLJ can be a double edged sword as it would also contribute to enhanced Warm air advection in the low levels (at and below 5000 ft) helping to cahnge the snow to mixed precipitation.
