A return to Daylight Savings Time all year long would unite America.
This satellite image taken at 8:45 AM isn’t showing clouds over Tennessee. That’s the snow on the ground that went south of us last night.
The snow that formed the basis of tonight’s Winter Weather Advisory has already come and gone.
This afternoon, we wrote that the approaching snow band would get here by 6 PM, and be gone by 9 PM. “If this model is off by 30-40 miles, or by a few hours, we could alot more, or alot less, than this, depending on which way it’s off,” we wrote.
We are included in the advisory. NWS expects up to 1″ of slushy snow for us.
The HRRR model agrees:
Let’s slow that down.
By 6 PM, the rain/snow (probably snow) will arrive from the west.
Last night, we wrote that the HRRR model predicted a “rain/snow mix” that was to end around 8 AM (this will turn out to be off by 2 hours, and off because it was all snow, no rain). The NAM3 model predicted precip will hold off until mid morning (it had the timing a bit better, but was way off on the precip type). Several models did not have this AM snow at all.
“Northwest Flow” is weather nerd for winds blowing from the north west. Our rain/mix/snow will be riding NW flow overnight through Saturday night.
Saturday will be cold. We won’t get higher than the low 40°s.
Our local National Weather Service Office will be conducting multiple storm surveys today as a result of last nights severe weather. One of the areas that they will be looking into is in Williamson County. Once we learn their findings, we will let you know.
Our severe thunderstorm watch has been cancelled prematurely. Catch some zzz’s to the rain! If you have any further damage reports, please tweet using the #tSpotter.
Friday
Rain will quickly end Friday morning, and then begins the rapid cool down. A cold north wind will take over on Friday, gusting as high as 20 mph at times.
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of Middle Tennessee
* Effective this Thursday night and Friday morning from 830 PM until 100 AM CST.
* Primary threats include… Scattered damaging wind gusts to 70 mph possible Scattered large hail events to 1.5 inches in diameter possible
As I write this update, it’s 77°, but our dewpoint is a very-dry 33°. Dewpoints that low aren’t going to fuel any bad storms.
But, storms currently in Missouri will surf a thin wave of higher dewpoints arriving in Middle Tennessee late tonight.
For those of you who have been enjoying these above-average temperatures, well you are sort of in luck. Tomorrow appear to be the last day, at least for the near future, with our highs climbing into the 70s.
