After all this time, we can finally cease our discussions (here in Middle TN) on Harvey. Clouds are still wrapping around the remnant low pressure system, centered over eastern Kentucky, leaving us with fair weather skies for today.
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.
We have several advisories and watches in place currently. The first advisory in place is a wind advisory. Expect for winds to stay a bit gusty at times through the morning thanks to remnants of Harvey.

Harvey’s rain is arriving.
Current rain is just the beginning. Most of it (the "bulk" of it) will begin late tonight, heaviest rain for entire event ETA Thurs night. pic.twitter.com/dEr31qhoKP
Latest HRRR Model Loop
A weak upper level impulse will slide further south today, sparking showers and an isolated storm in Kentucky and along the KY/TN border. One or two of these may meander far enough south into Davidson County, but the chances are low. Temperatures will stay in the mid 80s for afternoon highs. Otherwise, expect some cloud cover around…as already evidenced by GOES this morning (also, note the fog around Nashville):
Majority of the rainfall has moved out over the course of this afternoon. We do have a few lingering showers around the area, but nothing that an umbrella won’t fix. For those with plans to head out to the Nashville Sounds game tonight, rain should clear by then. We may see a stray shower but nothing to worry about.
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.
