Dry air arrived early this morning, and settled in this afternoon:
Colors indicate cold clouds tops (rain and storms). Grey is dry and clear.
The temp and dew point temps will be close together, so watch out for fog in usual spots near bodies of water.
This morning, a frontal boundary parked south of us. We’re on the northern, dry side of it. Behold mid-level infrared satellite images this morning. The coral, orangy stuff is the drier air. Green is the rainy air.
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 noon, satellite showed a weak weather system brewing to our west.
It’s moving this way.
Rain is likely later today and tonight. Showers will be hit or miss. Expect unequal distributions of rain in both our counties, and in Middle Tennessee as a whole.
Sunday will be fantastic. Low 60° dewpoints mean another day of low-for-summer humidity. The temperature will cooperate (High 90°).
Rain Monday and Tuesday is coming from the Plains.
Timing
That’s ^^^^ the HRRR model running through midnight tonight. Today’s storms in Oklahoma and Nebraska will shift east and weaken, but a few showers may survive the journey so don’t be surprised if you wake up to wet pavement.
Summer breeze, out of the north, 10 MPH.
An unusual-for-July upper level low is bossing our weather and bringing much cooler temps. Highs today and tomorrow: 84°! Only 84°!
Still a bit humid, but no oppressive humidity.
Light rain is moving closer and should arrive tonight, but do not expect a repeat of what we saw this morning.
All quotes (but one) from NWS-Nashville:
Many of the storms should dissipate this evening but the threat for additional storm development will continue overnight and Monday as the upper level trough approaches VERY SLOWLY before finally moving east of Middle TN. The threat of heavy rain will continue due to the rich moisture but threat for severe storms is muted due to marginal CAPE values.
Flash Flood Warnings are ongoing this morning in the counties immediately west of us.
Radar estimates through 9 AM show where the heaviest rain has fallen:
There was also 2″ of rain down I-24 in SE Davidson County, near/around Cane Ridge.
It’s Friday the 13th and an Intern broke bad by missing the “write the blog” assignment this morning which is what happens Friday, the Thirteenth and why you’re getting this at 6 PM.
