This isn’t happening. Everything on the northern edge in this airmass will dry up. Suppression is locked in. This is a rare setup where southern VA, NC, northern SC, and the Appalachians get major impacts in early December. Can’t bank on the northern shifts which really are not northern shifts. You are seeing the uncertainty between the southern extent and northern extent of the simulated model precip from run to run. The track and strength of the low itself is locked in. It’s not favorable to our region and will not change. You can will this northern edge all you want, best case scenario in D.C. and the immediate metro to NOVA is flurries. Areas south toward the southern extent of LWX CWA will see accumulating snow and impacts. Areas north will watch their southern neighbors get snow. The meteorology is simply not there for the majority of our area and you cannot force light lifting mechanisms into a suppressed dry airmass and get meaningful snow.
