I’m absolutely ripping the snow now .
-
I’ve got sleet and snow. About 50/50 right now. .
-
Nice returns now moving up the valley .
-
Wow. Unbelievable .
-
A friend texted me from west Knoxville and said it’s mostly snow with a little sleet but said it’s coming down pretty good .
-
Cannot tell by the cameras in Rockwood but the TDOT map has sections of red around that area. .
-
I cannot remember the last time interstate 40 was basically snow covered from Memphis to probably 20ish miles east of Nashville. Maybe around 150 miles or something? .
-
That’s beautiful .
-
Noticed this also. Was hoping for more east movement to take advantage of the column for a while. .
-
Getting a few flakes now. No sleet .
-
That’s what I’m hoping. .

I’m around 34-35 but my DP says 27-28° at several different locations around my house. Just now getting some returns over Knoxville .

Down to 35 .

MRX latest dance... .DISCUSSION... Doppler radar and surface observations indicate that precip has begun reaching the ground across the southern Plateau and southern Valley, and we have received public reports of sleet in Cleveland and 0.3 inches of snow in Whitwell. The potential for snow and sleet will spread north and east through Midnight as isentropic upglide continues to strengthen along with strengthening warm, moist advection ahead of the approaching shortwave. Surface temps are generally in the mid 30's to near 40, but dew points in the 20's will lead to evaporative cooling as the airmass saturates, which will support the wintry precip. RAP soundings show a warm nose developing near 850 mb as WAA increases, so snow/sleet mix will gradually change to more of a sleet scenario then eventually all rain as the warmer air makes it back to the surface. This will occur fairly quickly from S to N, and the HREF precip types support this idea with much of the S Plateau and S Valley through SW NC expected to be rain by 07Z while the middle Valley changes to rain in the 07-09Z timeframe and the N Plateau through the N Valley and NE TN into SW VA changes to rain in the 09-12Z timeframe (perhaps later in SW VA). The previous forecast and headlines look good, so the only change was to issue an SPS for Bradley, McMinn, NW Monroe, and W Polk Counties through 07Z to cover the current mixed precip .

Not sure what the wind is doing in middle Tennessee but it’s still out of the NE at my house just going by the feel of it. My area is wide open and I can usually get a good idea of the wind. .
-
Very interesting. I’m assuming they believe our thermal profile is good enough for sleet and snow east of the plateau? .
-
Interesting that TWC app has changed to 1-3” of snow for Knoxville .
-
Mping report of sleet in W Knoxville .
-
Huntsville just added a few more counties into the warning area. .
-
Snow? .
