Current Observations and Radar (trying something new)
We had a couple of no-quite-severe storms, including small hail in N Davidson Co and this wet microburst:
A look at the HRRR for the rest of tonight looks pretty grim for outdoor stuff:

Humidity is back!
This summer, rain has usually come from I-24 in Kentucky, moving SE towards us.
Today, that pattern reverses.
As I write this, a few renegade rain showers are working their way NW from the Chattanooga area.The HRRR model – although possibly exaggerating this feature – shows rain taking I-24 and advancing closer through all day:

Although we expressed uncertainty (here and on Twitter), I grade today’s “some rain” forecast like this:
I can point to the storms that formed 30 miles that way, or offer some explanation for the sunshine and attempt to sound smart. But really, who cares.
Current Radar
A lot of rain is piling up to our west. It’s being pushed by a weak cold front, which will arrive tonight.
Here’s what the HRRR thinks the radar will look like through 9 PM:
Current Radar
A cold front is coming, which means off and on rain is expected during the day. Blanketing clouds will keep temps from soaring to 93° (where we were Sunday).
We aren’t exactly sure when the rain will start. The NAM4 model thinks we’ll see it around 10 AM:

(Poor Mr. Belding)
The slim chance of rain did not materialize. We did see showers at the TN/AL border, but nothing bugging us.
We can’t completely rule out a shower from sprouting, but we don’t think it’ll rain tonight.

Experimental Radar
Humidity was low this weekend thanks to dewpoints in the 50°s and low 60°s. This ends today.
The dewpoint will move into the mid 60°s, a decent crank-up of humidity.
Current Radar
We hit 90° today, but the dewpoint never made it out of the 50°s.
The winds will shift from north to south overnight Sunday into Monday morning. So, hotter.
The dew point will climb into the upper 60°s.
Current Radar
Today dewpoints in the low 70°s will hang around Tuesday and Wednesday.
It’ll remain awful out there. The heat index (“feels like”) temp will range between 100° and 105° Tuesday and Wednesday.
Current Radar
The rain moving down I-24 this afternoon should be completely gone by sundown.
By 10 PM tonight, the dewpoint will rise to 73°.
That’s oppressive humidity.
The heat index will hit the triple digits by noon.
