Secure Loose Objects, Then Sleep Through It

Current Radar 

We did it!

At 1:35 PM, we hit 76°. Hottest December 13 since 1927, when it was 75°.

Strong Winds Tonight, Rain Overnight

Winds steadily increased through the afternoon. BNA even had a 45 MPH gust.

A Wind Advisory is in effect Sunday at 6 PM to Monday at 6 AM. Look for gusts up to 40 MPH.

These winds are coming from the south, which creates particular concern for high profile vehicles on I-40, SR 840, and other east-west roads.

Rain is on the way. You can track it on the radar at the top of this page.

The ETA remains a few hours after midnight. Here’s the HRRR model:

See that thin yellow strip?

Ordinarily, that would be the part offering strong/severe worries, helpfully called a quasi-linear convective system (QLCS), or a “squall line” to non-nerds. No scary QLCS tonight. The lack of CAPE and insufficient mid-level lapse rates are among the many things keeping it in its cage.

The winds ahead of this line will be the main show. Secure loose objects, then sleep through it.

Rain will probably still be around for the Monday morning commute, but the heaviest rain will fall before dawn. Under 1″ expected.

Monday – Still A Bit Windy; Not That Much Cooler – Early 57°, High 62°

Yeah, it’ll be cooler, but “cooler than near record heat” really isn’t December.

Winds will gradually calm down

through the day after the rain ends in the morning.

BTW, the NAM4 model advertises a little more rain around dark Monday night …

… yet the GFS and Euro models do not, and it’s not in the NWS forecast. I doubt it’ll rain.

December Returns Thursday

After a few uneventful days, a weak system will pass south of us Wednesday night, maybe bringing a little light rain. It will signal the return to normal temps, as colder air filters in behind it Thursday and beyond.

We may even get below freezing Saturday morning.
