Humidity will increase again Monday, somewhere between sticky and uncomfortable.
Low 90s temps with dewpoints in the mid 60s will make it feel like mid 90 temps in the heat of the afternoon.
From the National Weather Service:
Yesterday, for the first time in 2018, BNA hit 90. This was early: on average, we hit 90 on May 29. Look for highs today of 91, Monday 93, and Tuesday 92.
For us, yesterday’s heat was a “dry heat,” with dew points at or below 60. Dew points (the humidity) will rise today, tomorrow, and Tuesday, into “extra deodorant swipe needed” and “your hair will frizz” levels.
The HRRR was right this morning. Heavy rain, lightning, and small hail trucked through between 5 PM and 6 PM.
The HRRR thinks a little more rain is possible in the wee hours of the morning (before rush hour), but of little to no consequence:
It’s sunny now. Expect temps in the 80s.
Sunshine may not last all day. We may see a few waves of rain and storms tonight.
The HRRR model thinks rain with a few thunderstorms will race in from the north early this evening (5 PM or 6 PM or so), and again before midnight.
Temps will rise into the low/mid 80°s this week. Humidity is also rising, but it won’t be that bad.
Mornings won’t be as cold; Tuesday morning expect 51°, then mornings warm into the 60°s after that.
Gradually. 76° Monday, mid 80°s Tuesday through Thursday.
Through 3 PM, 1″ of rain has fallen at BNA.

Radar thru 6:32 AM shows rain inching closer to us.
You can update this radar on our radar/camera/tweets page here.
All models predict rain to work east and wash us out today.
The HRRR model thinks it’ll rain from mid-morning until 10 PM (and likely longer; this model only runs thru 10 PM):
We may see light rain or a few tiny snowflakes sprinkle windshields tonight, overnight, and early in the morning. Here’s the HRRR model:
Neither accumulation nor impacts expected.
This warning is effective from 3 AM to 8 AM Monday.
The front is very slowly pushing the rain east. Radar thru 8:25 AM:
High temps only in the mid-50°s.
Also, windy. Gusts to 20 MPH will drop wind chills into the 30°s tonight.
The HRRR model thinks a light, cold rain may freckle windshields tonight.
