Monday (Labor Day) will be fantastic, even with dewpoints in the mid 60°s bringing sticky and uncomfortable humidity.
Rain should last most of Tuesday, clearing out Tuesday night. Most outdoor sports will suffer a rainout if we get 0.58″ (up from this morning’s 0.36″).
Early morning fog has formed around water. Fog will mix out soon as the sun does its thing, revealing a great day.
A great two days, actually. Sunday (Live on the Green) and Monday (Labor Day) will be fantastic, except for humidity rocketing back up. Dewpoints in the mid/upper 60°s today and tomorrow mean uncomfortable, hairdo ruining humidity.
Y’all saw me frustrated (yet again) with Thursday night’s tornado sirens in Davidson County.
The main problems were:
(1) Tornado sirens alerted the entire county even though the Tornado Warning covered only part of the county. Areas unwarned were warned by the siren. Those outside the NWS warning area were confused when watching us and/or local TV. We’d say, for example, “Bellevue is not in the warning,” but y’all in Bellevue would clearly hear the tornado siren. It’s confusing.

Harvey's Rain and Storm (low tornado) Potential Tonight. Review and discussion. https://t.co/Fo8v6jqeu2

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:
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.
Clouds our west may bring rain 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.
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.
Late tonight or Monday morning or Monday around lunchtime, those clouds coming this way may bring us rain.
Expect a cloudy week, keeping temps below 90°. Humidity remains set to “Summer.”
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.
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.
