OK. OK. I'll make a thread. Hate leaving the Twitter crowd out of the mix...
Here's the latest thinking on totals. This is up from earlier today and the trends are higher. Doesn't mean it'll happen, but these are the trends. #tnwx
1/4
On top of this, if you live south of I-40 and closer to the Alabama state line, you're probably going to start out tomorrow with a mix of freezing rain and sleet (expecting less than 1/10th of an inch) and then the snow. #tennessee
2/4
All of this should kick off around these approximate times. This system should get through #MiddleTN pretty quick, only spending 3-5 hours in any one spot, but then....
3/4
Temperatures are going to fall below freezing tonight and stay there until Saturday -- with Friday morning's lows absolutely frigid. Anything that's liquid is gonna freeze tomorrow night, so prepare for very poor travel conditions both tomorrow and Friday. #winter

Here's a look at Google Maps with Live Traffic Data from 930pm CST. Tell me where the snow has accumulated on the roads, bridges, and overpasses without looking at radar! Hint: Where the interstates are orange and red!
We just received a few reports from Wayne and Lawrence Counties in Tennessee of snowfall measurements between 1.75 inches-2.5 inches. These are the highest amounts so far reported in Middle Tennessee.
The snow has mostly stopped in the Clarksville Metro area for the evening.
Remember, that the temperatures are going to DROP overnight, so check google.com/maps before you venture out, be PATIENT, and bundle up!
We're getting a LOT of questions about two things this afternoon:
- Timing/Duration of the Snow
- Expected road conditions across Middle Tennessee.
There's only one of those we can help with, so here's a graphic below to help in figuring out snowfall timing for your location.
As of 4PM CST, the changeover line for all snow is near I-65 now and will continue to push east through the evening. Snowfall amounts are still on track with our previous tweet.
As far as road conditions, we don't want to step on the toes of the Tennessee Department of Transportation, so please follow @myTDOT or your local jurisdiction for the latest road condition information over the next 24 hours.
1/12 Here are preliminary maps of the 15 #tornadoes from December 10-11, 2021 across #MiddleTennessee. Please note that the maps and all tornado information is PRELIMINARY and subject to change! #tnwx
2/12 #1 was a long track EF3 tornado that moved from west Tennessee across the northwest corner of Middle Tennessee and into southern Kentucky
3/12 #2 was an EF1 #tornado that touched down in northern Perry County and moved into Humphreys County before lifting in northwest Hickman County near Bucksnort, TN
1/4 UPDATE: We've determined a 14th #tornado occurred from the severe storms on Dec 11 - an EF-0 in western Davidson Co. that tracked from Whites Bend across Bells Bend to north of John Tune Airport & through Bordeaux. Path length 9.6 miles, path width 100 yards, max winds 85 mph
2/4 Damage in Madison from Briley Parkway at Gallatin Pike northeastward to Neelys Bend Road was determined to be from a swath of severe straight line winds around 1/2 mile wide and 2 miles long, with maximum winds estimated up to 85 mph
3/4 Damage in the Brentwood, Crieve Hall, Nippers Corner, Antioch, and Nashboro Village areas was determined to be from a large swath of severe straight line winds roughly 6 miles wide, with maximum winds estimated from 60 to 80 mph
Several rounds of active weather are set to start early this weekend. A mix of liquid and freezing rain will begin overnight and continue through the day on Saturday.
Locations along and east of I-65 may experience the greatest impacts with less than 0.10" ice accumulation expected. Minor travel impacts are possible, especially where roads are untreated.
While the first half of Sunday begins dry, a batch of light freezing rain and rain will arrive from the southwest in the afternoon. This could again create slick spots on untreated surfaces and roadways.
It is critically important that everyone have at least TWO ways of receiving warning information. This is especially important here in Tennessee where we lead the nation in nighttime tornadoes. We saw this Monday night.
(2/5) No technology is 100% dependable. Phone lines can go down. Weather can take down transmitters. Cell phone settings may override the audible alarm on weather alerts. Please, don't put your life in the hands of only one warning method.
(3/5) NOAA Weather Radio remains one of the most dependable alert systems. But even this should not be relied on by itself.
And please heed this important note on tornado sirens: THEY ARE ONLY MEANT TO BE HEARD OUTDOORS. A tornado siren is meant to alert you to get inside and
