Harvey is sitting and spinning in Texas. It’s so large, high cirrus clouds are spinning off into Middle Tennessee.

Harvey is flooding Houston, rivaling and exceeding our May 2010 flood.

By comparison, here were our totals in 2010: read more

Sunday, humidity will rise a bit (not too bad). Mid-level moisture blowing off the top of Harvey (centered now in Victoria, Texas) may sneak in some clouds and shower, but no model really thinks it’ll rain enough to bother outdoor plans. It probably won’t rain at all, but don’t be surprised if we get a little. read more

Clouds our west may bring rain tonight.

Tonight

The HRRR model thinks very light rain will start sometime after dark, as shown in the below animation (Sunday 6 PM to Monday 2 AM):

Some rain may not reach the ground. And to look at the radar, yeah, looks like that rain is coming, but I’m not sure it’s making it all the way down. read more

Today brings the week’s best weather. Lower humidity (north winds!) and temps only 87°.

As I write, clouds stream east to west from Arkansas.

Rain on the Way?

Late tonight or Monday morning or Monday around lunchtime, those clouds coming this way may bring us rain. read more

Expect a cloudy week, keeping temps below 90°. Humidity remains set to “Summer.”

Rain & Storms Tonight

As I write this, storms are breaking out all over Middle Tennessee.

Look for two rounds of storms.

Round 1

Storms developing on top of us, or south of us, beginning now until Round 2 arrives. These storms should work their way north. They are not widespread and you may not see anything at all. read more

Yesterday’s weather was a fall preview, it wasn’t the full length movie. Although cloud cover will keep temps in the 80°s this week, humidity is on the rise. Expect dew points in the upper 60°s this week. That’ll be sticky and gross. read more

Dry High Pressure Monday & Tuesday

Expect a cool Monday morning. 63°.

We’re going to heat back up again. High 89° Monday, 90°  Tuesday.

Humidity will rise every day this week.

Monday’s humidity will be sticky; Tuesday will be almost uncomfortable. read more

Another Glorious Sunday

Breezy, low/no humidity, high 87°, sunny. Winds should top out by mid afternoon around 10 MPH. Probably not enough to support a kite.

Little Hotter, Little More Humid Monday

But first, another cool morning! 63°!!!!

Totally agree.

High 89°.

Dewpoints will climb out of the 50°s and settle into the low 60°s.

And a Little Hotter & More Humid Tuesday

Another kinda-cool morning, 66°, then up to 90° by mid-afternoon.

Rising humidity, with dewpoints approaching 65°.

No rain is expected through Tuesday.

Pattern Change Begins Wednesday

Goodbye cool mornings.

The dewpoint will creep into the upper 60°s (“uncomfortable” range), and with that comes maybe an afternoon/early evening pop-up shower or storm. Wednesday is outside the range of the short-range models, leaving us with little/no additional information about whether it will rain on us (Davidson and/or Williamson Counties) or other parts of Middle Tennessee. No severe weather is expected.

Shortwave Thursday Bringing Rain Chances

What’s a shortwave?

Yes, that. Also this:

Also known as Shortwave Trough; a disturbance in the mid or upper part of the atmosphere which induces upward motion ahead of it. If other conditions are favorable, the upward motion can contribute to thunderstorm development ahead of a shortwave. read more

The official high at BNA today was 96°. We briefly reached 97°, but we were not there long enough for it to be official. The heat index got up to 106°.

Tonight’s rain event is mostly over. You have to look east or west for the heavier stuff. Here’s what the radar looked like at 8:00 PM. read more

Heat Advisory Until 7 PM

It’s been another scorcher.

BNA reporting 93°F, dewpoint 75°. Heat index 105°. pic.twitter.com/gwhKBXakV7
