Really good to see the GFS starting to catch on with the coastal band. Could be another surprise event for the lowland folks, if we see this last through 00z runs, I'd be more bullish of this being an overperformer.
3k NAM has a Montgomery/Howard/Carroll/Fairfax/Baltimore county jackpot. Disregard the snow map panel in this image. It still snows after this screencap. Cold powder.
Tomer Burg on Twitter has been hammering this home for the past couple of days. Global models might be a too dry/under estimating some banding that short term CAMS could pick up on. (Yes, he has a New England focus, but the same applies for I-95 crew)
I'll take the 12z NAM in a heartbeat. This is a relatively fast moving system, but it falls at night and could give folks a surprise 3 day weekend. What's not to like?
06z GFS usually comes in dry or warm it seems. Everyone panics then 12z calms folks down. To see it give us a decent event gives me hope. Also, GFS seems to handle northern stream storms better than the Euro.
Set your sites reasonable. Expect an advisory level event. This is going to potentially be another event that we could steal within a week of being close to 20 degrees above normal.
FWIW, 18Z GEFS is more enthused than OP for snow. It has a 60% chance that DCA, IAD, and BWI exceed 1" snow. That's usually a good sign for an advisory level event in these parts. I'd post the graphics but they're through a paywall site.
