KEY MESSAGES
Updated at 731 PM EDT Tue Oct 6 2026
- Dry weather to continue the rest of the week.
- Temperatures to remain above normal with a gradual warming trend each day.
- Tropical development is expected over the Gulf which may impact the Tennessee valley and southern Appalachians this weekend.
DISCUSSION
Issued at 227 PM EDT Tue Oct 6 2026
Dry northwest flow aloft (PWs from 0.6 through 0.9 inches) and surface ridging will be the main weather features through Friday. A dry and weak frontal boundary will move across the region late Thursday. Areas of patchy fog is possible near area waterways almost each night. Temperatures will be 5 to 10 degrees above normal.
For this weekend into early next week, an upper trough over Texas will pull tropical moisture northeastward. NHC still favors tropical depression development with a 90 percent chance of formation over the next couple of days.
A good deal of uncertainty of the strength of low pressure development and path. Latest tropical advisories indicates a near 100 percent chance of depressions within the next 48 hours. Latest GEFS tracks suggest a track into the Tennessee valley or southern Appalachians over the weekend. Given the tropical-like moisture some locally heavy rainfall is possible.
Also, depending on surface low track and expected surface wedge east of the Appalachians, tightening pressure gradients could produce strong and gusty winds especially over the far east Tennessee mountains and foothills. Currently, the greatest threat of strong winds will be late Saturday through Sunday morning.
This system will move east of the area by late Monday with upper ridging building into the Tennessee valley and southern Appalachians for Tuesday.
