January 28th-29th Clippers/NW Flow Obs/Last Minute Forecasts.

[Silas Lang]

I ended up with what looks like around a half inch here, maybe a little more. I just caught the edge of one of those bands. 

[fountainguy97]

4" of powder here. Rates pushing 2" at times.

High-res performed horribly but some of their longer range runs hit it right on the money.  I think the low DGZ and moisture caused them to really struggle.  HRRR only showed snowfall along the heaviest showers but reality we saw a pretty widespread area of light/moderate snow from the NW flow.

I give MRX crap at times, mostly because I’ve got to take my frustration out on someone lol. That being said it’s just about impossible to figure out where the streamers are going to setup. The mods did struggle with the valley around Knox Co. They all showed that enhancement streamer coming from Scott, Morgan, Campbell and Anderson Co but they stopped it at the Knox Co line and that didn’t happen. West of 75 through west Knox Co picked up 1-2”. It looks like everyone who was supposed to get a couple of inches actually got 4+. NW flow just doesn’t do well in the valley, especially in my area unless there’s a wave or clipper.

Picked up just a half inch here. Far NE Lee County picked up several inches as well as all of Wise County. Western Lee County picked up 1 to 3". 

     Not a single streamer moved over here. Just western and eastern sections the County.

[John1122]

Ended up with 4.1 inches it looks like. Sunny and 14 with ice crystals blowing around outside. Areas just west of me where the band was around earlier had 5 inches.

[Coach B]

Only had a dusting at the house, but it looked like half an inch just a couple miles away. HRRR and NAM 3K nailed the idea of minor accums from the streamers in middle TN.

And it's just been sitting in one spot for hours with temps in the teens. They're in foot in 3-4hrs territory. Would love to see that here but it'd take serious arctic air, low sliding across the gulf, and getting REALLY lucky with the bands

[RawCrabMeat]

Accumulation around my area is odd, in the sense that the typical shady yards on a slope didn't do so well, and some people's yards will have a good inch while the next neighbor has nothing or patches, with the same sunlight. That band was VERY localized down to fractions of a mile

Very awesome satellite shot of the snow streaks across the valley. I live on the edge of the streak that came out of Cumberland county across Rhea, Meigs, McMinn and Polk I ended the event with just under an inch, but 3 miles northeast nada.

Check that streak out from western Lee that stayed intact down thru the heart of the upper valley. Several inches western Lee co. from it . KMRX measured an inch and a half from it at their Office.

This person had a bad night

That looks like it could have been a lot worse though

This is a basic map for downsloping off the Plateau in Tennessee. 

[RawCrabMeat]

There's still snow in the shade... having some fun doing some pitching practice. Any of you guys like to nail trees from a distance

That's what I was thinking. If that tree hadn't stopped them, their next landing spot would've been a creek about 50ft lower

That’s awesome man!!

I was amazed today at the difference in snow amounts in my town Oak Ridge. I live on a ridge in the center of the city and we received a coating of snow. I went for a walk in the south eastern section of town today, down in the "bottom land" near Melton Hill Lake and they had a good 1 1/2 inches of snow and icy roads in places.

There was amazingly sharp cutoffs outside those bands in the valley.

My weather gauge has quickly dropped from 20 down to 14 after the sunset. That can't be right? Monterey and Crossville are reporting around 19-20.

I'm at 16, there's a 15 and an 18 nearby. Areas with less snow are near 20. Do they have less snow now than your area?

I'm not sure how much Monterey has, but Crossville has less than here. It was just strange how quickly it dropped from 20 to 14 and the other stations a few miles away in either direction were around 18-22. I did go out to check and everything looked good and it was freezing cold for sure with crystal clear skies. Now it's holding steady at 15. Our low tonight is 19 though so it must be rising through the night.

Seeing that the interstates in Knoxville had more brine than I had snow (.77” vs dusting)……my wife and I went on a 10 mile hike in the GSMNP. We started at Chestnut Top trail, went down Schoolhouse Gap to
Laurel Creek Rd. Since it was closed, we walked the last 3.7 back on the road. Temp was 21 when we started and 28 when we finished. I would guess the max depth of snow to be around 3”.

[John1122]

MRX map for this one. It is not correct here. The 3 and 4 inch area in Campbell isn't big enough. I saw their storm reports had LaFollette at 3.2 inches. It's 2.4 on here. They have a Co-op site in NW Campbell,  they erroneously reported 1.8 inches of snow there in their local reports. It was corrected a couple hours later on their storm reports page to 4.8 inches and they mention the correction. Yet the spot in NW Campbell where the 1-2 inch circle is is at the area of the co-op site. 

They are generally the official reporting station in Morristown, we know they reported 1.5 inches, they report 0.1 on the map for some reason. Knoxtron reported 1.5 inches by McGhee-Tyson, Stove reported 1.25 at least,  Knoxville listed as 0.2. 

They even made a point to put out the map of 1.5-2 inch snow streaks this morning but they don't appear on this map. 

This is why snowfall averages and data can't be trusted here. It's chronically underreported.

Same thing here. I have started taking my measurements and reporting them here.

So far, every report has been used! I've noticed the same thing here as far as severely under-reported snowfall. But not anymore with my reports!

Mine did the same thing last night. The lowest I got was 15 at 11:30 . I have friends across 70n who measured 13.7, which is close to your reading  . My grandfather used to tell me that this was one of the coldest spots in the area, so I guess he was right. He was the county agent for Cumberland and was interested in weather also , I got the bug from him for sure

We were in Knoxville yesterday for a band event at UT.  That NE streak on I81 laid down a lot of snow on the interstate.  We went rom nothing to lots of snow(snow had fallen the night before...we saw the aftermath) to a winter wonderland in about one mile.  Then, the interstate went down to one line.  There were a couple of tractor/trailers jackknifed.  By the time we hit the Jeff City exit on I-40 it was pretty much gone.  I had to put the vehicle in 4WD on the interstate.  Super sketch conditions.
