BlunderStorm

It was then that the eastern valley rejoiced with the post-Christmas clipper, all was well... And not a single flake died upon landing that night. *Although approximately only 3 flakes reached @BlunderStorm's backyard he was happy nearly everyone else scored with the darkhorse clipper event that Carver had "masterfully prophesized".

Merry Christmas folks! Hope all of yall are doing well. Weather wise this 'Eve I reached a high of 10.2 and received a couple more tenths of wispy powdery snow to aid in some window dressing for the season. In the end not really a white Christmas, not really a brown one, more like a "silver" one. At the end of the day though I count my blessings that I have electricity and warm a house. It sure was fun discussing and observing this one guys, all the best. With any luck we might be back in business again for the clipper.

Sub-zero at -1.3. Not really flurrying but some microscopic ice crystals are sparkling under light. Maybe picked up from the wind, not sure.

I recorded a high of 6.6 at 2:30 and have been steadily dropping since. Now it's 1.4. Feels like temps have averaged roughly in the lower negative teens.

I'd be almost shocked if it didn't go negative tonight man. I mean, we saw this coming but this is some crazy stuff!

Update: After a short power outage and some shut eye. Fortunately we had propane heaters (ventilated just in case) for just these types of situation and battery banks, so it wasn't anything too bad at least for us. As for the snowfall here accumulations were negligible. Roughly a 1/10th of an inch stuck, fairly disappointing all considered. In other words where one part of the valley is shafted, so is the rest for this one. No latitude nor elevation gain could save me with this one. With that said the temps have been quite impressive. Up to now I've been holding steady between 4 and 5 degrees. I suspect it'll make an afternoon rally but I'd bet money double digits aren't on tap. The severity of lows tend to correlate with a west to east gradient where comparably the cold has more time to settle in for most of yall.

Winds ramping up to roughly 10 sustained with 20+ gusts. Meanwhile temps remain steady at 42.

https://www.wymt.com/weather/cams/ The WYMT Studio Cam shows it absolutely ripping during the transition in Hazard KY.

@Kentucky@Jesse from KY@AnthonyEC How're things going west of the KY/VA line fellas?

42 and rain starting to sprinkle. Front hours away, gonna be skating rink.

Granted, the Euro in the past few runs threw us somewhat of a bone but I digress... lol

I love seeing reports from the deep south getting some flakes out of these systems. You know there's got to be some really excited kids down there wanting something even resembling a white christmas. (all negative aspects brushed aside)

Dang, was really rooting for that smooth transition... Here's hoping your switchover is quick!

12-23, 06z averaged precip on the Euro over the past 6 runs.

I have 3 limiting factors I've become conscious of, 1) Big A Mountain downslope for NW flow events. 2) Clinch Mountain downslope for Miller A events. 3) Warm air advection heading all the way up the Clinch to my doorstep although less than everyone SE of me. I think the big issue for Grundy is the low elevation, it's hard to flush out the warm air from the maze that is the Appalachian Plateau.

A moment of silence for @BuCoVaWxfrom that SWVA GFS screwjob. lol. I'd say the same to kv and carver joking too... but the kingsport snowhole is a genuine phenomenon.

Thus far the anecdotal evidence presented from the high plains is indicative of an overperformer. With that said I'm not sure how that translates east of the Mississippi 24-36 hrs later. Are we clutching at straws or is there a realistic possibility models are slipping with this? At this point I'd be monitoring available moisture like a hawk.

I'm excited for the new extreme analog will get from this event should it ever come again in the next few decades. This is the ultimate "cold crashing into the valley" scenario.

Was it this one? "Octavia" as the WC dubbed it was the most snow in a day I can remember up my way. 16 inches! I believe on Feb 16th of 2015. https://4.bp.blogspot.com/-kf3uvQ71W_A/VOKJlBhTAfI/AAAAAAAAAhI/401QH79ixiQ/s1600/radar.jpg

06z 3kNAM Kuchera map on Pivotal sure is a beaut for most.

06z NAM is solid and an improvement from 0z. Notably the valley snowhole SE of Knoxville to Chatty is still there but smaller.

Even more of a negative tilt if anything, the slp is 40 miles west and 2 mb deeper at 54. A better run for west and central TN, though it sputters out over the great valley.

At this range I'm not sure if that is a positive or a curse. But yeah, I like what we're seeing with the more robust anafrontal precip.
