January 2021 Medium/Longterm Pattern Discussion.
John1122 replied to AMZ8990's topic in Tennessee Valley
Was just coming to post about the EPS that Carver's just posted about. We are going to have to ride out a rainy/mild period for the next 10 days or so, but good things should be coming for peak winter, Jan 15th - Feburary 20th or so for the non-elevated valley. -
Sadly, not quite snow. Just unending rain.

One more day of snow on the ground in the books. The new years eve storm may get me to 100 inches on the year if it over performs.

Miller A's in January and February are by far our best way to get a big snow. Average low temps forum area wide in mid January are cold enough for snow. It mostly just has to not be well above average. The EPS above had 850s well below 32 with a storm signal in the gulf area and monster blocking over the top in the extended. If we also got the slight bump into +PNA territory it would be the rare winter triple play. Historically those periods are snowy and cold here. -

The strat warming is actually underway now. Whether we benefit or not remains to be seen. By by and large we eventually see more snow than normal in the 60 days that follow. -

The blocking by day 8-10 on the Euro is just crazy. The EPS just says "hey Miller A, meet this cold" in the 11-15 day range. Now we just need to reel it in and we should have business picking up. -

Eric Webber says the strat split will likely couple with a west based -NAO and likely give us the best Atlantic based blocking since 2009-11 winters. He's pretty enthusiastic from Mid January on about it. Granted I think he's in Eastern NC and that may mean different weather for him vs us. But a powerful -NAO should help us all. -

Always favor the Pacific. We had a +PNA heading into the Christmas eve event. It's looking to hang out around neutral to mildly positive the next two weeks. It's not easy to make things work here and especially any further west of me, with a PNA that isn't at least neutral or some big time EPO help. -

I'd love to see West and Middle areas get a big winter storm this season. The ice they probably don't want. Some of the ice scenarios showing up rignt now would be crippling to the power grid. -

Hi-res GFS crush job out West. Regular GFS is a severe ice storm too. Memphis just stays at 31 for a long time with freezing rain. The Canadian is a a little further West and just makes a glacier in Texas, Oklahoma and Arkansas. -

Looking at that image, the biggest snow drought area is basically over the NAO region. I wonder if that's a result of a -NAO there after SSWs? -

This is the composite 0-60 day snowfall from 1958-2014 after all SSW events, both splits and disruptions. The lightest blue is a 10 percent increase in average snowfall the darkest is up to a 50 percent increase. I had to drop and rotate to get a decent look at the United States. Our forum region does as well as any other area in North America after a SSW. -

Looking at SSW events between 1958 and 2002, if the SSW happened in December/January in most cases the 60 day snowfall here was above average. If it happened in February or another month, snowfall was more often below average for the next 60 days. -

After getting .20 to .60 or so of freezing rain West Tennessee, West KY and NE Arkansas gets this. -

GFS shifted towards the Euro that run. Might have a thread called "AMZ's New Years Rockin Eve" or something like that if the west shifts can stop now. -

Was at 12 by 9PM last night and thought I might make a run at 0. Only got down to 5 though. -

The EURO shifted south with it's frozen shield at 12z and isn't bad for West Tennessee. I suspect it and the GFS will eventually meet. It seems like it's been folding towards the GFS this winter. -

Canadian is a cutter, Euro/GFS are very close to the system we just had. Let's see if it sticks around. The system yesterday was constant for a week. -

I was wondering how those middle Tennessee streamers were doing. There looked to be some very heavy ones north of you. -

Just before sunset it was dropping huge flakes. I was at the Cumberland Trail head getting some drinking water out of the natural spring there. I picked up another 1/2 inch in that band. 5 total for the event. Still flurries flying around out there. -

I posted that and the sun was peeking out. As soon as I looked back outside it was like living in a fog cloud. Amazing how badly the NAM missed these snow showers. The Canadian suite nailed them. -
