At 11 PM Saturday, the temp was 73°.
While you were sleeping — at least I hope you were sleeping — the temperature dropped to freezing. As I write this (at 4 AM) it is 32°.
Around 3 AM or so, a cold rain transitioned to freezing rain, and freezing rain transitioned to sleet. I hear the sound of the sleet right now.
The NWS Storm Prediction Center has issued a * Tornado Watch for portions of Northwestern Alabama Southeastern Arkansas Northeastern Louisiana West-central through northern Mississippi Southwestern and middle Tennessee * Effective this Saturday night and Sunday morning from 855 PM until 300 AM CST. * Primary threats include... A couple tornadoes possible Isolated damaging wind gusts to 70 mph possible SUMMARY...A band of strong to locally severe storms near an intense cold front will move across the watch area through much of the overnight hours, offering a risk of sporadic damaging winds and a couple of tornadoes possible. Isolated severe storms still may form ahead of that band also. See SPC mesoscale discussions 1893-1894 for initial meteorological reasoning. The tornado watch area is approximately along and 55 statute miles either side of a line from 25 miles west northwest of Monroe LA to 15 miles east of Nashville TN. For a complete depiction of the watch see the associated watch outline update (WOUS64 KWNS WOU8).

Our high temperature of 69º will arrive shortly after noon, between 1-3pm, in addition to gusty southwest winds in excess of 25 mph. Very humid air has already engulfed middle Tennessee and will continue to hang around with us until showers and storms move through later on.
A powerful storm system will move across the Tennessee Valley this weekend, bringing much warmer temperatures to Middle Tennessee today and especially by Saturday. Showers and a few thunderstorms are also anticipated Saturday afternoon and into the evening. Some storms may be strong to possibly severe. Saturday night, an arctic cold front will sweep across Middle Tennessee, bringing much colder air back into the area. As this occurs, rain may changeover to a wintry mix of freezing rain or sleet late Saturday night into Sunday morning before precipitation ends. However, only light ice accumulation amounts look possible at this time.
There is good news and bad news with today’s drought index update. The good news is we did not get worse. The bad news is we did not get any better really. Both Davidson and Williamson Counties are included in the “severe drought” category once again.
You may need to let this page load. Lots of stuff in it.
20° Thursday morning, with winds to 11 MPH, driving wind chills into single digits at times.
We’ll stay below freezing the rest of the day. High only 30°.
The next few days will be rain-free and particularly chilly from tonight through Friday morning.
We currently have a series of high pressures set up to our west, as shown below.
High pressures have a clockwise circulation around them, so since they are to our west, these high pressures are causing for our winds to be from the North and thus bringing in cooler air.
By dinnertime, a cold front moving from the west will be over-top of us, raring to bring below average temperatures for the rest of the week.
Lots of sun is expected the remainder of the week, but a cold Arctic airmass will keep afternoon temperatures way down.
Cloudy skies will prevail throughout the remainder of the day and into tonight.
One of our short term models has now decided that it wants to put some light showers over our area tomorrow.
Showers, if we see any, should be fairly scattered and brief. The AM work commute could be wet and you may need an umbrella heading into the office tomorrow morning. NAM 4 has the showers drifting around through the morning, but mostly gone by the lunch hour.
