We can start comparing the actual storm to model forecasts. Rain has already made it to Huntsville. Expand Yep, gonna start putting more emphasis on the short range models as well. Also for CLT to RDU seeing what's happening real time is gonna be crucial. I'm really curious to see if the 12z NAM trends colder..I'm almost willing to bet it does. 2 Link to comment Share on other sites More sharing options...

wxduncan Posted December 7, 2018 Share Posted December 7, 2018 Do you guys think this will continue to trend south? If so would that put the foothills out of the 12-18 forecasted and move it to CLT? Link to comment Share on other sites More sharing options...

Just because it moved south doesn't man the bullseye moves south with it if the cold air doesn't do it's thing. WNC is still in the best position right now.

Nick Esasky Posted December 7, 2018 Share Posted December 7, 2018 Haven't seen much discussion of N GA based on the overnight runs. Is ATL pretty much out of the woods as far as significant ice?

Expand I think we are going to see mostly rain and maybe a slight possibility like you are saying on the back end of the event. Models have been very consistent regarding the wedge from the NE. The 850 tropical temps are going to keep it an all rain event for ATL. The NE portion of GA is where the action will occur and that is even being discussed as minimal impacts. The area we need to monitor will be early monday morning to monday night. That time frame is still uncertain with the short range models just now bringing it into frame.

Has close to 3 inches of QPF for most of that 30 inch area...850's look pretty good. So cut the actual snow ratio down a bit and you're still at like 12-20 inches if that were to verify. Expand What if it is correct? I see all the models trending south, hence, this has to mean the cold air is stronger/dryer? I would think this has to bode well for us snow hounds?

Rankin5150 Posted December 7, 2018 Share Posted December 7, 2018 With this being so close to the start of the Winter Storm tomorrow, I feel we need to remember to not lose sight of looking at Radar Trends. They can tell a lot. For example, look at the expansiveness of the moisture. WOW!

LovingGulfLows Posted December 7, 2018 Share Posted December 7, 2018 This system is pretty far suppressed so far. I think folks in VA might get whiffed outside of the southern portion and even they might not get much. Link to comment Share on other sites More sharing options...

Poimen Posted December 7, 2018 Share Posted December 7, 2018 The FV-3 is another whopper for western NC. The Kuchera map is insane again.

Not as user-friendly as some of the larger sites but for a stand-alone site, it does pretty dang well.
