Fall/Winter Banter - Football, Basketball, Snowball?
John1122 replied to John1122's topic in Tennessee Valley
I have a friend who lives at the base of the mountain there and he literally gets about half the precip I do a year. -

12k NAM isn't far off from the 3k, it just doesn't handle the dynamic precip areas as finely as the 3k. Will have to see if they are just NAMing but it's been a big shift towards winter weather over the last two days. -

Ends up here. Would be a true paste job on trees and powerlines. Comes at a good time of day. -

That purple in the deep blue is some 40dbz+ snow. -

3k NAM is rolling in hot for the west and mid Valley. -

I'm skeptical too. I guess it's rate driven and that's allowing it to get below 3000 feet and stay snow on the Euro. -

Its dumping right on my head right there. It's insistent on that happening for multiple runs in a row. -

Euro was similar to the GFS/NAM and it's 12z run with snow over the Plateau/SEKY and even a bit of unelevated Middle Tennessee. Also shows wave two beginning as frozen at times across the area before changing to rain. -

Sounding on the 3k when snow breaks out here. It was showing near 40 on the regular NAM yesterday. -

3k NAM hits the Plateau and SE Kentucky pretty decently. Probably cut the snow maps in half with probably 5 or 6:1 ratios at best. -

GFS moved a little towards the Euro for my back yard. Probably more elevated than my actual back yard. The global models tend to paint a little too broad with their snow output maps. But it does appear likely rate driven dynamically cooled snow falling. Has a dollop of 6 inches a few miles away. -

The 12z Euro looked like an early December 2009 paste job here that put down 8 inches of heavy wet cement overhead while it rained north, south, east and west of here. For whatever reason this county was just in the perfect spot in the storm and it dropped silver dollars for 5 straight hours. It was mixed slush about 15 miles away in Scott and Whitley County Kentucky but just hammered here. -

Looks like the 18z American models are having issues. My friend has a few acres for sale at 2900 feet. So tempted to move but I'd have to sacrifice things like reliable internet and you know, build a new house plus convince my family moving to fulfill my snow obsession is a good idea when I can drive to 2900 feet in 5 minutes or so. It would probably double my snowfall yearly though. That extra 1200 feet makes a huge difference. I think that area here will probably get several inches of snow out of one or both systems next week. I believe the snow level was down to 2660 feet on a sounding I looked at that showed rain here during the overnight runs. I don't think there's any private land above 3000 feet here anywhere. The government owns it all in some form or another be it WMA, State Park or the Air Force I think owning the 3500+ land on Cross Mountain. The top there averages about 55 inches of snow a year. -

The Euro is back to me getting 2 or 3 inches Monday. It's going to be razor thin for a lot of us next week. -

Overnight modeling is all too wound up/further north. Very cold rain with snow above 2500-3000 feet. Need everything a good 100 to 150 miles south but there's not much to force it down and cold is extremely marginal. -

Wave 2 is weaker and further north. -

Too warm on the Euro this run on wave 1. Jamestown gets some heavy mix. The rest of us stay liquid. -

GFS is slowly working it's way more towards the more snowy models. 12z today it bad virtually nothing in the mountains. 00z it buries the mountains with 6-10 inches. Bigger and longer lasting precip shield in general too. -

The ICON has a 1 to 2.5 inch event basically for some of middle to the Plateau. Doesn't really hit the far Western areas like the NAM did. -

RGEM is slower/warmer than the NAM. On the NAM the Northern stream wave gets out in front of the southern system. On the RGEM the northern wave is more in synch and is sitting in the great Lakes when the storm is getting going. That shuts down some of the cold for the system on the RGEM so it's a rainer. -

The NAM rolled in guns blazing for the West and Mid Valley. Fizzles for the East Valley. -

In the 1960s it snowed here no matter what it seems like. -

Ventrice also tweeted earlier that the Westerly OBO was beginning to affect the Troposphere and that could possibly weaken the MJO convection for a while. I've never researched it for here, but for Atlanta's winter events I believe GaWx found they mostly occurred when the MJO was in the C.o.D. Generally if Atlanta is having a shot at snow it's cold here and we've had it too. -

The weeklies had probably their snowiest run of the winter season so far. It wasn't spectacular but would represent something close to normal for most areas through January 25th. The snowiest 4 weeks we have are basically January 17th-February 14th so the Weeklies are just reaching there at the very end. It was around 4-6 inches in Eastern areas, 2-4 Western and southern areas. -

If I were guessing most of the big -NAO storms that hit eastern areas come when the Pacific is also favorable. The best temperature set up obviously comes when all three are negative. But when the EPO is negative in conjunction with the AO, basically everyone in the South, west of Raleigh to Columbia is colder when the NAO is positive than they are when the NAO and AO are negative but the EPO is positive. So our ideal combination is -EPO/-AO/-NAO, followed by -EPO/-AO/+NAO, then +EPO/-AO/-NAO. We are rarely dry for long but it can happen. Getting cold is always our biggest step towards wintery weather Valley wide and it's much easier when the Pacific is working for us instead of against us.
