Today. The record for October 30 is 84°, set in 1950. We’re forecast to hit 85°, but that may not happen as a weak trough moves our way, lowering the humidity and denting our heat-building high pressure dome just enough to maybe keep us below 85°. Still, that hot.
Gonna be a hot few days, y’all.
NWS-Nashville wrote this afternoon: “It won`t be a dry heat, either. [Winds blowing from the S/SE] will keep dew points in the low to mid 60°s both days, so relative humidity values will be elevated to make it a little sticky — but not summertime sticky.”
Here’s how much it’s gonna rain between now and Wednesday night.
Yeah, nothing. High pressure is in charge.
Your crap app probably has a chance of rain for Thursday:
This cold front is “moisture starved,” meaning, we don’t think there will be enough moisture around for the cold front to do what it normally does, which is rain a lot.
A cold front will arrive mid-day Monday, bringing clouds and a little rain.
By 9 AM, the rain will be in west TN.
It’ll be packing our first real taste of fall weather.
Expect the rain here around/shortly after lunch, with the cooler, drier air filtering in behind it. Maybe a few lightning strikes are possible, but meh. Expect a little rain, probably not enough to rain you out.

Today will be the last day of above-average temperatures for the week.
Then this:
As of the current forecast, today`s high of around 93 will be the last time Nashville will see above 80 until next Saturday.One more day of summer weather.
Same as it was yesterday. Hot. Some humidity, but not oppressive humidity.
No models show rain, which makes meteorological sense because high pressure is in charge, pushing away any rain chances. That high pressure will be out of here tomorrow.
Most of it is going south of us, but sometime before midnight, expect a little light rain to fall. The HRRR model illustrates:
Otherwise, we are shenanigan-free.
Steady sunshine returns Monday. The dewpoint will stay in the low 60°s for more than 48 hours.
We will accept your “when’s it ever going to stop being so hot” complaints Thursday, when fall formally starts.
Looks like high pressure to our east late in the week will send us more heat and humidity for the weekend. And, yeah, there may be some rain, too. But, that’s to be determined. From NWS-Nashville:
Our next shot at rain could hold off until the end of next weekend as models are fairly consistent in showing a large upper level system pushing out of the Pacific Northwest Friday and its cold front reaching us by Sunday night or Monday of next week. However, even with the model continuity that far out, will carry only a chance probability of precipitation as this is Day 8 and things will likely change by the time we get there.
Especially south of 40:
Again, this is likely an overestimate. We won’t know for sure until the Cocorahs data starts showing up with actual measurements.
Rain and clouds are lined up along this purple line. This is an infrared satellite view, showing that the rain has finally moved east of us this morning:
