SHORT TERM
(Rest of today through Friday) Issued at 1127 AM CDT Thu Oct 8 2026
Our warm, dry weather is hanging on as northwesterly flow aloft keeps conditions benign at the surface.
Afternoon highs will be in the 80s today and nearly 90 in some locations tomorrow with overnight temperatures dropping into the 50s and 60s.
LONG TERM
(Friday Night through next Thursday) Issued at 1127 AM CDT Thu Oct 8 2026
Hurricane Isaias is forecast to make landfall along the Gulf Coast tomorrow, dissipating as it moves NNW. Shower and thunderstorm chances will increase from south to north early Saturday and peak Saturday afternoon through Saturday night.
This tropical system will bring an abundance of moisture, likely producing 1-3" of rain across the area (highest south of I-40).
Although we need the rain given the ongoing moderate to extreme drought across Middle TN, our prolonged dry conditions will reduce the soil's ability to absorb water and will increase our chances for flash flooding.
Therefore, a Flood Watch is in effect for portions of Middle TN from late Friday night through Sunday morning.
Wind gusts up to 30-40 mph are expected and a few brief spin-up tornadoes are possible Saturday afternoon and Saturday night.
Tropical tornadoes can form and dissipate quickly and can develop from weak showers or storms.
Conditions will improve through the day on Sunday with the last of the rain clearing the area by Sunday night.
At the start of next week, warm and dry conditions will return with daily highs in the 80s and overnight lows in the 50s and 60s.
