As I write, a line of heavy rain and gusty winds is passing through. Follow us on Twitter for the deets.
This storm formed thanks to a weak cold front over the Mid Mississippi River Valley – both associated with a larger scale trough crossing the Great Lakes.
Summertime heat has returned and we are going to feel every bit of it today. The high temp will hit close to 95°, with heat index values pushing into the upper 90°s.
Any rain showers or storms popping up over us will be caused by daytime heating and the breaking of the cap. Where they’ll form is anyone’s guess. The HRRR (below) takes its shot at a prediction.
Looking at a high of 92º today with a heat index in the mid-to-upper 90ºs. popcorn shower and storms. Not everyone will see one, but if you do, be prepared for heavy rain and gusty winds. Chance of rain is at 30%.
I found my contact. It fell on the floor. I washed it then located my glasses.
That mid-afternoon thunderstorm did this:

I’m writing via Chromebook in an Atlanta hotel. Not optimal. I’ll be light on graphics this morning.
Today’s dewpoint will climb close to 70. That’s near-oppressive humidity.
Today’s high is 93. Add that to a more humid airmass and you get a heat index up to 97 this afternoon.
At the 4:00 pm observation at BNA this afternoon, the temp was 94° with a dewpoint of 62°. It’s hot! Temps should cool to 72° tonight with rain chances very low, although a few spotty showers aren’t out of the question.
Temps and humidity will rise this afternoon. High today 91º, with dew points remaining in the mid to upper 60°s. That’s not oppressive humidity. Pretty much normal for early August.
This weekend will be hot, humid, and mostly dry.
High temps will stick close to 87° today, dewpoints are holding steady in the upper range of uncomfortable.
We’ll experience a typical hot, humid, summertime storm pattern today. The HRRR (below) has a few storms going up over Davidson and Williamson counties in the early afternoon.
If you were mostly east of I-65, you got some OK rain overnight. Cocorahs observations:
Today we’re stuck on the line between wet and dry.
Rain is happening to our east, divided by a surface front over Middle Tennessee. Sinking air (shown by yellow arrows below) has set up west, behind the front, harshing our rain vibe.
Skies will be cloudy for much of the day. Good news: clouds will keep our high temp from soaring. High temps in the mid 80°s and dewpoints in the upper 60°s.
GOES-16 Low-Level Water Vapor Imagery shows low pressure slowly swirling over the Midwest (near St. Louis). It’s pulling moisture straight up into Tennessee, keeping our storm chances high.
