3k nam looks good too, 12k maybe a bit overdone but they’re not that far apart.
-
Nam gets northern folks in the game too
-
Halftime show already over? Didn’t realize. Was too busy reading the storm thread
-
I know its only the half, but it feels like the game is over.
-
WOW! Philly is killing it right now.
-
What pass interference? They aren’t playing flag football sheesh
-
As much as I want to say 5-8”, I was too bullish last time so I’m staying conservative this time. Different storm, different scenario though. Better cold air this time except right at the surface, which can be overcome with moderate rates.
-
That’s just smoothing across all ens members. But they’re converging on a max between dc and ezf. Still time to tick north, but probably not by a whole lot
-
As a counterweight, here are gfs and euro soundings. Hrrr doesn’t go that far out, and rgem weirdly doesn’t have soundings on TT but guessing a degree or two warmer than 3k nam.
-
For posterity. DCA at the middle of the storm
-
Biggest forecasting question for this storm, from a regional POV, is where the heaviest banding sets up and is someone going to see double digit totals out of this.
-
9” dc metro per NAM. i’m thinking 7” high end. 3-6” most likely
-
Agreed. The s/w for Tue-Wed is still off the CA and Baja coast. It will enter the conus tonight or early tomorrow morning.
-
Combine the 12k and 3k nam and we get the best of both worlds
-
NAM shows coastal enhancement that beefed up qpf imo
-
You’ll be fine on temps. It’s more for 66/50 and south as well as the UHIs
-
I think the one with higher amounts is computer generated, and the other was edited by a human. But that’s just my guess. 2-5/3-6” seems reasonable considering the marginal surface temps. Someone might good banding that could add an extra inch or two. 8” max upside
-
Could be right for the UHIs. Burbs like Ashburn and Columbia could see 1-2” otg before dark, then it’ll become easier to tack more on afterward.
-
Fixed. It’s hard to do this on mobile lol
-
Sorry I used the wrong snow map. Fixed it, looks even better
-
Qpf 10:1
-
Wetter. Good slug of moisture thru TN
-
At 63, more moisture and beefier precip shield
-
NAM shifted north too, at least with the precip shield
-
Not much difference in track vs recent runs of other models
