According to the HRRR model, around 9 AM Monday, a rain/snow mix will be crossing the Mississippi River near the Missouri bootheel:
This timing matches well with the NAM3 model, which thinks the rain will be here around lunchtime, and last for a few hours:
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.
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.
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.
