Mid Week Snow
So this snow storm we're getting was puzzling me. Normally we see a system either coming from the west or up the coast, but here we are a day out and there's NOTHING out there. I had to look at the forecast maps before I could figure it out: https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
Basically, the low currently just NE of Texas will move south of us, while the high to the north of us will hang on like a stubborn child. This creates a pincer that funnels strong winds between them; blowing off the yet somewhat warm Atlantic then over the eastern seaboard that will be rapidly cooling at night. Comparatively warm moist air spewed over a frigid surface: hence the heavy snowfall.
Before the advent of weather models I doubt many people could have forecast this storm just based on surface measurements and balloon vertical profiles. It's impressive how far we've come.
