.DISCUSSION...
Issued at 1259 PM EDT Wed Oct 8 2025

A cold front has moved southeast of the region with northerly
winds advecting cooler, drier air into the region. Upper-level
northwest flow and surface high pressure will develop across the
region with clearing sky conditions and dry weather. Cool
temperatures are expected the next few nights with some 30s
possible across the higher elevations of the East Tennessee
mountains and southwest Virginia. We should remain dry with high
pressure in control through the weekend.

Upper-level ridging increases across the Lower Mississippi Valley
early next week with southwest flow aloft and a warming trends
across the Tennessee Valley. Isentropic lift will result in some
increasing mid to high level clouds, but with a dry airmass at the
surface, limited to no precipitation is currently forecast.

A pressure gradient will remain across the area overnight,
maintaining some winds that will prevent fog development at all
sites. Some clouds around 5 kft are expected to spread into the
southern TN Valley tonight, creating broken cloud cover at CHA
starting around 08Z, and possibly persisting through the day.
