What happened to the really cold air we were seeing modeled yesterday. No problem and no offense taken at all. Cold air and plenty of it is still there. If the you looked at temps only, you would think the trough was in the East on the 18z GEFS post 300 hours. At 500 (300+ hours) the trough shifts West but temps don’t drop here. The surface pattern remains cold while the pattern aloft is different. The EPS and GEPS are plenty cold. I think models are very likely trying to break down what will be a verify as a very stubborn high latitude block. Link to comment Share on other sites More sharing options...

He can correct me if I'm wrong, but I think he's talking about a 500 mb pattern: that would normally look like it has a SE ridge/ developing eastern ridge (we might expect warmer than average), but looking at the temp anomalies: there seems to be some cold air hanging around. (Although I would say the 850s don't look quite as good): 9 minutes ago, weathertree4u said: What happened to the really cold air we were seeing modeled yesterday. As much as I enjoyed that, it was the product of a very peculiar and specific set up that dropped the TPV into the CONUS. If that were to be modeled again, or actually happen, it will return. Heck, it could be back at 0z tonight or 18z tomorrow because to be honest, we are talking about 10 day + modeling. Link to comment Share on other sites More sharing options...
Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 Just now, weathertree4u said: All right, that makes more sense to me, thank you! I looked this up on Google so hope this is correct...500mb is at about 20,000’. The surface temps are at 2m. So the pattern at 20,000’ is not the same as it is at 6’ which, while not rare, can be a bit unusual but very cold air will often be very difficult to root out.

Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 FTR, I do think the GEFS is likely way to quick in breaking down the pattern...just something to watch. Like I mentioned earlier, the Weeklies control run built cold over the NW for a few days and the trough was then forced back into the SE. Link to comment Share on other sites More sharing options...

BNAwx Posted January 20, 2019 Share Posted January 20, 2019 Hoping the back-end precip doesn’t fizzle out before it reaches Nashville. The last HRR I looked at (few hours old) looked decent for perhaps a dusting...maybe more if we’re lucky enough to get under a heavier band. Down to 37 now...

John1122 Posted January 20, 2019 Author Share Posted January 20, 2019 The comma may reach Nashville before it starts dying. I'd say most people west of the Plateau along and north of 40 at least get a white ground. Link to comment Share on other sites More sharing options...

It was about as good a run as one can get at this latitude. If anyone has the attachment space, feel free to post the 16d total. Starting to see some consistency in terms of big ensemble runs showing up roughly 2/3 of the time. Also, thanks to everyone out west for providing updates on the snow.

Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 TRI is at +6.7 for the month so far...that number has been cut in half over the past week or so. I think there is a pretty decent chance that number gets taken back to neutral or even slightly BN. Should be really interesting to watch as the last few days of the month may be very cold - not to mention the next few days as well. Minus a few warm days next week, looks like we are now going to enter a base cold pattern. Link to comment Share on other sites More sharing options...
Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 Out to 186 on the 0z GFS...pretty cold run going and great set-up so far at 500 that would bring very cold air into the Upper South. Link to comment Share on other sites More sharing options...

Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 Another note...I think maybe what is going on in the LR might be related to storms firing in the Indian Ocean. Per JB, those storms signaled the big December warm-up. He noted that they are supposed to settle down this time incrementally over the next 2-3 weeks. IDK...seems like later in the season should mute that. JB also noted this might signal a second stat warm. So, we might be seeing high latitude blocking fight off the affects of the IO convection, and that might be why we are seeing the cold bank against the Rockies on some runs. Food for thought.

Carvers Gap Posted January 20, 2019 Share Posted January 20, 2019 One thing to remember as we deal with microclimates that seem to get less snow than surrounding areas during winter wx events...remember our ancestors moved to these various microclimates because the wx wasn’t as bad as surrounding areas. These mini-banana belts often see less extremes. Pretty smart folks. Link to comment Share on other sites More sharing options...
