It would appear on the radar from WGAL that the backend is quickly approaching areas such as Blair, Bedford and Fulton Counties. Is that the end of their radar's reach or are we wrapping things up a little early?

I like to use this for wide views although it's sometimes not updated as much: http://radar.weather.gov/Conus/full_loop.php

Does seem to be ending early.

Any thoughts on the 18z runs?

Ptypes on GFS still imply thump snow down to Harrisburg before mixing and maybe ending as liquid, NAM a bit warmer than that. I didn't really see any mind blowing difference really. I'll be curious to see how the 21z SREF's (that incorporates 18z runs) pans out later this evening. 15z was starting to light up C-PA pretty well with snow probs. I see HPC finally adjusted their snow probs further southeast as well.
