.DISCUSSION...
Issued at 145 AM EDT Fri Oct 16 2026

The ridge and high pressure over the Southeast break down as a 
deep trough moves into the Midwest and then into the Ohio Valley 
by afternoon. The surface low will move through the Great Lakes 
and into New England bringing a cold front through the Tennessee 
Valley this afternoon. Winds will be gusty this afternoon and 
evening with gusts up to 30 mph possible at times. The best chance
for showers will be Southwest Virginia, Northeast Tennessee and 
along the East Tennessee mountains and foothills this afternoon 
through tonight. Elsewhere, showers, if any, will be isolated. 
Thunder chances will be low with low instability expected. A 
changeover to light snow in the late night/early morning hours 
will be possible on the highest mountain peaks with little to no 
accumulation expected.

This weekend will be dry and much cooler with highs in the 50s and 
lower 60s Saturday. Saturday will be breezy as well with gusts up to 
25 mph likely at times. Only slightly warmer on Sunday with highs in 
the mid 60s. Temperatures will be cold enough for frost on Saturday 
and Sunday nights mainly in Southwest Virginia, Northeast Tennessee 
and the higher elevations. 

Early and mid next week will be dry with highs warming into the 70s 
by Tuesday as ridging and high pressure dominate the Southeast.
