Wonder if that means they resolved the generation issue they had or if they are supplimenting with energy bought outside TVA region. Wish they'd tell us what power generation plant/station went offline and what happened. Sent from my SM-F721U using Tapatalk

Yep that was cold for me too but not as cold as up your way. I'm on the unofficial border of the Southern and Central valley terminology that MRX uses. I can walk into the Central Valley but my house is technically in the Southern Valley. I live right near the county lines of Meigs and Roane. Definitely up the valley your direction tends to be colder than down this way. Think Chatty even which is about 75 miles south of me is mostly in the single digits today too.

I've lived in the valley of east Tennessee since 1989, I cannot recall a daytime temp peaking at 8 degrees. My weather station has been fluctuating between 6 and 8 degrees all day. The coldest day time temp I can recall since we moved here when I was 10 years old is in the low to mid teens for daytime hours. My forecast high from MRX yesterday was a high of 16, not going to hit that. I suspect tonight may go negative air temp. All that said my official high for the day is 45, just after midnight.

Winds starting to roar here and switching to WNW. Temp is beginning to drop have fallen a couple degrees in the last 15 minutes as the wind switch direction. Sent from my SM-F721U using Tapatalk

Same here poured off and on a good bit over the last hour here. Gonna be a lot of frozen puddles and icy patches on the roads. Sent from my SM-F721U using Tapatalk

Still active snowfall reports as far west as Memphis. Not really showing on radar out there. Sent from my SM-F721U using Tapatalk

Getting closer snow is at the western escarpment of the plateau. Sent from my SM-F721U using Tapatalk

Looks like it's blowing quite good from the camera link. Sent from my SM-F721U using Tapatalk

That's exactly what I was doing loaded up as much wood I could in the house for tonight. Glad I have wood for secondary heat, feel sorry for folks without secondary heat if the power goes out and electric is their only heat. Think you are going to do well where you are. Fingers crossed downslope don't get me. Sent from my SM-F721U using Tapatalk

Have gusty SW wind here ATM, hopefully it's transporting lots of moisture up the valley to get trapped. Though for being gusty SW wind it sure is chilly. Sent from my SM-F721U using Tapatalk

Your topo is why I do better with Northerly flow. I'm due south in the valley of the sort of gap between the mountains around Frozen Head and the higher terrain down around black and hinch mountains. Generally I do better when the flow funnels through your neck of the woods vs a west wind. Not only do I do better there seems some weird enhancement when the wind funnels through there.

This is what I am hoping here, under forecasted event, that busts high. There is absolutely a chance for anyone in the forum region to bust high. Sent from my SM-F721U using Tapatalk

For only 2-4" which I suspect isn't there normal requirement for WSW, think they are trying to make a statement with the public about how bad its going to get with wind driven snow. Funny though with only 3 inches of snow with the forecast windspeeds there will probably be drifts up to 2 feet deep in places. Sent from my SM-F721U using Tapatalk

Don't know if anyone has noticed but the Blizzard warnings have expanded westward back to Montana where the front had already passed yesterday. Which means if NWS offices out there didn't think it was necessary to issue until well after fropa then the winds and overall strength of the storm and its impacts were underestimated yesterday.

Definitely an improvement for the valley considering earlier runs the valley was blanked almost entirely. Sent from my SM-F721U using Tapatalk

Right talk about treacherous! Sent from my SM-F721U using Tapatalk

I've seen the same from Watts Bar nuclear plant, steam blowing SE in a very cold single digit night with NW winds, back in early 2000s I worked 3rd shift drove under the steam cloud from the plant in an otherwise fair night sky with stars, and flurries were falling right under the steam cloud! Wild stuff, I've told people that over the years who didn't believe me. Awesome someone else with similar experience. Sent from my SM-F721U using Tapatalk

Also sorry for quoting you twice, but that makes me wonder about all the trapped low level moisture stuck in the valley that doesn't fully dry from downsloping. I think that could ignight in the same manner and not even be seen on radar. Sent from my SM-F721U using Tapatalk

Great example!!! There have been so many examples of things modeling just couldn't simulate because it's so unprecedented. Sent from my SM-F721U using Tapatalk

Most similar arctic front anafrontal type events I'd just barely follow for the valley, but this being really unprecedented in modern modeling history I think it's game on for this to work out in ways they don't typically. Remember there is not a true analog here, there are similar systems but no true analog for this potent a system. Sent from my SM-F721U using Tapatalk

I think we are going to be stuck in a nowcast situation with this. There have been many things occurring in the plains the last 12 hours that were not modeled correctly even on the hi-res models. Storms of this magnitude don't happen often enough for the models to handle them well. Sent from my SM-F721U using Tapatalk

Yeah they added "Heavy snow" verbiage to my point forecast too and I'm in valley. Think all the reports from the plains has them spooked that even with small amounts of snow the conditions could be severe, even Blizzard like at times like as have been seen so far. Places that only got an inch or 2 like Cheyenne still got Blizzard like blowing snow conditions for a few hours. Sent from my SM-F721U using Tapatalk

A snip from MRX 3rd shift discussion. "I have been forecasting in the Southeast for 23 years, and I have never seen an outbreak of combined cold and wind like this one. This will be a potentially life-threatening cold event if precautions are not taken. Please see our office social media pages for infographics on how to stay safe" Sent from my SM-F721U using Tapatalk

I just don't buy the complete blank of the valley. The plateau has an effect of downsloping but I think it's exaggerating that effect as though the plateau has the elevation of the smokies. I think the models are overdoing the downsloping and underestimating the speed of the cold past the great wall of the Cumberland. Sent from my SM-F721U using Tapatalk
