John1122 Posted January 24, 2019 Author Share Posted January 24, 2019 The Euro dries out, so the GFS gives two systems and 16 inches to me. I'm sure it'll change by 12z. Link to comment Share on other sites More sharing options...

Holston_River_Rambler Posted January 24, 2019 Share Posted January 24, 2019 I think you'd have to get the trough over the Dominican Republic. That one above orients the flow out of the W and SW. Hour 186 on the 0z Euro gives a Wintery Mix to Gainesville, FL though Link to comment Share on other sites More sharing options...

But hey, we got something inside 7 days now, sort of (6z GFS and 0z Euro Kuchera snowfall through Jan 31): In all seriousness, this event has some legs (admittedly maybe those of a drunk grand daddy long legs). Results matter and remain to be seen, but it has been pretty consistently modeled for a while now. Link to comment Share on other sites More sharing options...

John1122 Posted January 24, 2019 Author Share Posted January 24, 2019 The 0z UKIE is also a decent system for our forum area, except for the strange snowfree streak along the Southern/Central Plateau and far western areas. Pretty much only the Euro looked bad for the area overnight. Link to comment Share on other sites More sharing options...

The standard 10:1 or the Kuchera Ratio? Thank You Tim Whichever gives us the most is the one I prefer. LOL. Just kidding...well, sort of. Link to comment Share on other sites More sharing options...

I think that there are times when FL gets very light ocean effect stuff(obviously very rare). Seems like I remember Tampa at one point getting some very light bands coming off the Gulf.

HSVWx Posted January 24, 2019 Share Posted January 24, 2019 Question: IS the upcoming pattern change next week now displayed via most Ensembles with such dramatic daily low morning temps, is this a "cross-polar"/ PV event? Thank you Link to comment Share on other sites More sharing options...

Thank you You know, I think the cold likely resulted in part from one of those parent vortices from the strat split earlier this month. I haven't looked closely. It may very well be from across the pole in some part as that is likely how Canada reloaded. The reason it gets really cold is the snowpack to our north and some models even have light amounts over us. This is a very cold air mass coming Link to comment Share on other sites More sharing options...
Carvers Gap Posted January 24, 2019 Share Posted January 24, 2019 Going to keep my Jan29-30 comments in this thread since it is still January, and place my medium to LR comments in the Feb thread or until we are tracking an event in February... Still looks like a nice Arctic front event around Tuesday next week. Those can be fickle beasts. Sometimes they are under modeled and sometimes the sputter. Just think about rainy fronts during spring and summer. Many times the amount of precip is not modeled well. The Plateau is doing well with amounts as it gets just enough lift to squeeze out some moisture. Old school front there as someone mentioned. I do like our chances after that for some high ratio stuff in NE TN. I will add those comments in the February thread. Link to comment Share on other sites More sharing options...
Holston_River_Rambler Posted January 24, 2019 Share Posted January 24, 2019 UKMET looks hopeful for your part of the state, @jaxjagman maybe the Euro will follow: only 5 days to go now, we've broken the 7 day barrier on something besides the Fv3 and GFS!

Daniel Boone Posted January 24, 2019 Share Posted January 24, 2019 I don't know what has been done to some models lately or what data is being ingested but, they have been forecasting temps too warm for Lee County and underforecasting precip. Snowfall projections are wrong as well, generally too low. Even the once decent (Euro model) for the area is doing it now, as well. Link to comment Share on other sites More sharing options...
Holston_River_Rambler Posted January 24, 2019 Share Posted January 24, 2019 @weathertree4u "Ratios are higher with arctic front aren't they?" If you can get the air cold enough they would be. The site I use for the UK doensn't use Kuchera ratios though. Link to comment Share on other sites More sharing options...

Makes you wonder if maybe they are working from an updated topo map. Wonder if they have the elevation incorrect, or the borders drawn incorrectly by a hair.

I've noticed that sometimes the Euro shifts the mts precip to far west into the valley sometimes and the valley's warm nose too far west too. Will see if I can catch it doing it this run.

That area is fairly complex as well. It is possible that the elevations have been smoothed a bit much as well. Just guessing. I know in this area, that happens. We will see 12" of snow on Roan Mountain and 2-3" of snow here...what that really means is no snow in the valley. I do think models have higher definition than they used to...but I bet the elevations over there are getting smoothed out or they have the map wrong. Let us know if you find out anything. Interesting. It might apply here as well. Link to comment Share on other sites More sharing options...
nrgjeff Posted January 24, 2019 Share Posted January 24, 2019 I'm pretty confident the cold hammer drops next week. Models debate which days. However they are not punting. Big supply of cold air will be delivered to the Midwest and East. Some of it is coming south. Could be a lot of it. Broadly, the arctic outbreak is gradually progressing forward in the models. Adds confidence. MJO convection looks friendly to cold bulls, though much of the action is south of the equator. Philippines cold fronts, lol! So far I can't see snow in CHA. Post frontal and/or low north does not work here. However if current trend hold, I'd expect snow on the Plateau into the Mountains. Probably TRI. Maybe more parts of I-40, but I like Plateau and I-81 better. PS. This might not flow well with the current page. I jumped at the end of page 28., See Carver's post there.

How long did that article front last CG? It was over and gone in about an hour, maybe less. Dropped like 2-3" of snow during dismissal. I was a car rider.
