Yea, as @Bob Chill said. Big high to the NW and even Ian on Twitter is liking the potential. Next two to three weeks could be really interesting. Peak climo for cold temps too.
12z GFS w/ 41" at IAD, 33" at DCA, 29" at BWI in the long range. Somehow, Ji will scoff at this, but holey moley am I excited about the next three weeks. Could be an epic time. Haven't been this optimistic since 2009 - 2010.
If this system was just a bit more organize and juiced, some folks would've probably hit double digits. No worries though, we went from 60s this past Sunday to two snow events. Not too shabby.
One thing is for sure, once it starts snowing it comes down with a thump. Everything but the roads starting to get covered and it only starting snowing in earnest about a half hour ago. Definitely some good dynamics aloft helping this thing.
For those of you tracking on radar at home, if you switch to the lowest scan on the Correlation Coefficient, once the values get over ~85%, it starts snowing a bit. By 90% it's full snow. There's definitely a dry layer though...it was mangled plates and needles for a good 40 minutes before the legit snow started.
