UPDATE:

Good Afternoon Tennessee Valley,

A Flash Flood Warning remains in effect until 8:30PM EDT for Hamilton, Rhea, and Meigs counties, Bradley, McMinn, and Monroe until 7:15 PM EDT and Marion and Sequatchie until 5PM EDT.

The entire Channel 3 viewing area is under a Flash Flood Watch through Thursday evening.

With this said, we've picked up 1" of rain today, and an additional 1" to 1.5" is very likely for the next 24 hours. Since Monday, we've picked up 5" of rainfall, placing rainfall totals well above normal for the month of September. As of today, we're at least 2" of rain above the normal rain for the month.

Tonight, rain will continue through 8PM-10PM before breaking and lighting up. Additional showers look to develop early on Thursday morning. At this time, we can't rule out heavy rain again Thursday morning beginning by 7AM-9AM increasing late morning through 11AM-1PM tomorrow. 

The best rain chance by Thursday afternoon looks to be from I-75 and east. Additional, but isolated showers will return on Friday.

We've been telling you about a possible cool down by the end of the week. Forecast models have become in better agreement for some cooler air to settle in Friday night. While it won't be cold, temperatures will drop to near 60 in the valley and upper 50s in our higher elevations come Saturday morning. Saturday looks to be the pick of the weekend, with partly cloudy skies, lower humidity and a high of 80. By Sunday, humidity starts to creep back up with temperatures warming to the mid-80s.
