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.
The next 48 hours will include much of the same, bitter cold that has invaded the central and eastern U.S.
Warm air begins to advect (propagate) into southern and middle Tennessee during the day on Sunday. The center of high pressure that was entrenched over-top of us keeping our temperatures down will slide east towards the Appalachians, and relatively warmer air will arrive to replace the chill.
The day has finally come that we have been talking about for quite some time now, our first dose of winter-like weather.
Keep in mind over the next couple of days, we will see some calm winds of about 5-10 mph. While this doesn’t seem like much, this wind will add in wind chill. Expect for it to feel even colder than those high temperatures (the wind chill isn’t forecast to go above 32° tomorrow and this is what it is going to feel like).
Afternoon continues to be pleasant with temps reaching the mid 40s.
A cold front is set to pass through tonight and behind it, very very cold temperatures (more on the meh rain/snow chances later). To end the work week, we will finally be seeing those winter-like temperatures. We could even drop into the teens for the first time this year on Friday night.
A dividing line between relatively warmer air and very cold polar air is expected to reach middle Tennessee later this evening. Behind this cold front, temperatures will fall below freezing overnight.

Over the course of the next few days, some of the coldest air of the season will take control, per NWS Nashville:
Friday and Saturday mornings we are looking at the coldest temperatures thus far this meteorological winter.
Have a look at this temperature fall-out from Thursday through the first half of the weekend:
Needless to say, your winter wardrobe will be out in full force later this week.
There’s no reason to be very excited about this, but the first flakes of the winter are always of interest.
Another wave of energy will eject out of the mid south late Wednesday into Thursday morning, bringing enough moisture to send a few showers our way. This event will be a “sleeper”, or one that occurs overnight, into early Thursday. At times a few snowflakes could mix in with the rain, but as expected, no accumulation is even remotely possible.
NWS Nashville:
...we could see a chance for light rain here in Middle Tennessee after midnight possibly mixing with a flake or two of snow over northern areas of the Mid State along the higher elevations...
Rain has stayed clear of us so far today, but into tonight, we will begin to see those showers pushing into our area.
We could begin to see spotty showers by this afternoon, but we think the majority will hold off until the early evening hours.
