CAMs still adding about 2-4" around Knox with the Lee -

Not liking the 3k NAM FZR totals for my area...it's closest so far on ground truth temps. -

And this is in response to the Lee if it forms up MRX AFD: The same guidance suggests a surge of colder air aloft will arrive tonight, potentially leading to light snow tonight -

This is the part that's gonna catch alot people off guard in the rain areas. MRX AFD: any wet roads will undergo a flash freeze tonight as temperatures fall into the teens and winds remain light. Black ice is a near certainty, and road crews will be challenged with the low temperatures. -

According to CAMs it's beginning to form now...should see it fully formed around 03z -

TellicoWx replied to John1122's topic in Tennessee Valley
One of the tricks it may be up to, is Lee are notorious for being under modeled 6+ hours out on precip. If it hangs around as CAMs suggest tonight, could be interesting for everyone. -

As the pressure has started to rise, the 850s can start pulling back south. Add in the rates able to tap that, time of day it's occurring, downslope winds starting to ease up and switch..and you have a great recipe. Look at the time stamps of the valley PWS coinciding with everyone posting how goose feathers have picked up. -

While this has been a very complex and surprising system..don't think it's done with all of its tricks. -

That definitely didn't help matters..more heating makes it harder to scour out, especially if you lose radiational cooling. Bath tub theory..clouds act as a partial clog to drain out the heat. -

TellicoWx replied to John1122's topic in Tennessee Valley
Great analysis...I think in the end the wave that generates the Lee Low wasn't well handled. Once in range the models start being able to hone in so to speak. Combine it with the plateau slowing things down naturally...it stalled and pushed back the Arctic air, especially at the downslope prone areas. With the pressure stabilizing now, more areas are going to be on the correct side of the Lee. Allows the artic to resume its push. -

Pressure has bottomed and leveled..wave has passed by and temps are responding (Sweetwater PWS). If you have stayed all snow...buckle up buttercups..you are about to be rocked lol -

Yeah you guys are gonna get rocked..wouldn't be surprised if some in the valley will go over a foot. -

TellicoWx replied to John1122's topic in Tennessee Valley
For those stuck up against the base of the mountain and rain..the HRRR, which has been fairly accurate with the snow cutoff imby, has slowly been bumping totals up last couple runs for later this evening. Is it right, who knows, but may not end up completely blanked. -

TellicoWx replied to John1122's topic in Tennessee Valley
Congrats, hope you guys can score om that side. We are fighting a SE wind..got up to 15-20 as the temp jumped. Until that switches directions we are out of luck. -

At least I can use my rain gauge to help figure out the ratios lol
