Finished shoveling and it’s tricky because the slight slush film leftover refreezes in all shady spots. Unless it dries out by dark there will be some tricky and disguised icy spots.
That’s an explicit idea and although I was rebuked about where the main center of circulation is, it seems like you concur? When NWS was jumping all over the place late this morning they had DcA mixing by now then reverted back to snowfall slightly past dark. We are losing the high pressure support but the low well may end up east of here and not over or west. 1994 had one like this but the snow only lasted 30 minutes then low 20’s freezing rain. Right now low would have to head NW to end up west of DC. Memories of that kind of move from on the coast are very rare.
David is perhaps the best discusser I know of what it takes for the area to get big snow versus not. Unfortunately, for reasons that elude me, he is much less skilled at accurately predicting what an individual event will do.
