Wintry Feb 17-19 Smastsmasher Snow/Ice

Yeah I find it hard to believe it snows til morning and only snows a couple inches especially with snow still on the ground and temps around 20

The question will be how quickly precipitation can fill in over DFW late tonight/early tomorrow before it move eastward. The other models aren't as quick to do so, and everything blows up just to the east.

Huge bust potential either way with the instablity, lift and moisture advertised.

Yeah a big range possible for sure

Super tiny flakes just started here

I feel better being north of DFW for once lol

I know gfs doesn't do well with warm nose, but still holding out hope we can trend this to more sleet on front end.

As Webb has said, 850s are not supportive of much, if any sleet. I've found that for all ATL sig. sleet with wedging that 850s were usually ~+1 to +3. For ZR, +3 to +8 has been the most prime when there's a good wedge.

Is 1-3 inches of snow before switching a good bet here in Roanoke, VA? Currently thinking somewhere between Nam and gfs. Nam IMO is too aggressive with warm nose up here but gfs not aggressive enough.

18Z GFS/12Z Euro suite consensus averages ~0.25" of qpf. I think the NWS' raise from 1" to 1-3" was a good move. Assuming 0.25" qpf, it would give ~1" if it is pure sleet and 2.5" if it is pure snow.
 
Getting chilly here as the sun sets 29° with a forecast low of 23° will be watching temps/dews in the morning which will probably tell the tale last few ice events/nuisance haven't had the low level cold like this one will so it has my attention.
