Warm weather through Thursday with high temperatures well above normal. Record highs possible through Thursday. Medium to high rain and storm chances Wednesday afternoon and evening, primarily for areas north of Interstate forty. A cold front will arrive on Friday bringing much cooler temperatures into this weekend. Who ordered all this extra autumn heat? I would like to speak to them right now! An upper level ridge is parked across the southeast, Squashed against the sky, burning out the autumn shroud! Nineteen forty-seven records falling at the station! Lapse rates seven point zero, atmospheric desperation! The National Blend of Models brings fifteen degrees above normal! The humidity builds, the atmosphere is far from formal! Break the record set in nineteen forty-seven! We are burning up beneath an open sky! Sweating through October up to 91 degrees! Watch the mercury climb high! 91 degrees! Northwest quadrant opening up along Interstate forty! Instability rising, convective energy distorting! Showers in the afternoon, a rumble of thunder! A stalled out ridge pulling autumn under! Friday brings a dry front to break the thermal wave! Ten degrees below seasonal norms is all we crave! But another ridge rises in the long range vision! Fall will never stay, a endless collision! Break the record set in nineteen forty-seven! We are burning up beneath an open sky! Sweating through October up to 91 degrees! Watch the mercury climb high! 91 degrees! The heat returns next week! It never leaves! 91 degrees!

Who ordered all this extra fall heat?
I'd like to talk to them.
Whoever it was brought an upper level ridge into the southeast US yesterday and it's going to be parked over us for the next few days.
We're currently forecasting record breaking highs today, tomorrow and Thursday at Nashville (BNA).
Not by much, but still.
Today's record high is 88, tomorrow's is 89 and so is Thursday's -- all set in 1947. NBM suggests afternoon highs of 90-91 through Thursday -- and all about 15 degrees above normal.
So that's fun.
Now, the ridge isn't a big north-south amplified high.
It's a little squashed and this will open the door for areas along and north of I-40 (especially the northwest quadrant) to have medium to high rain chances tomorrow afternoon and into the evening hours.
These will mostly be showers, but I can't rule out a rumble of thunder and gusty winds with any storm.
This is a very low chance, but worth mentioning as mid-level lapse rates are decent (~7.0) and plenty of instability will be around due to the heating I mentioned earlier.
On the whole, the ridge will win out and most of Middle TN will remain dry tomorrow.
LONG TERM
(Friday through next Tuesday) Issued at 1129 AM CDT Tue Oct 13 2026
Once we get through Thursday, a dry front is going to deliver autumn back to the mid-state.
Models are very consistent bringing this front through here on Friday and providing a break in this heat.
The weekend looks dry and cool -- maybe 10 degree below seasonal norms.
Yep, I said "a break" in the heat.
We may not be done with it yet.
The cooler temperatures want to stay, but models are relatively consistent bringing yet another upper ridge into the southeast US next week and providing above normal temperatures once again.
Obviously, that's a week out, but fall doesn't look like it's here to stay and other than the rain in the north tomorrow, continued dry conditions will be with us until *at least* this time next week.
