.DISCUSSION...
Issued at 1240 AM EDT Sun Sep 27 2026

In the upper levels, a ridge is over the Great Plains and a closed 
low is just off the coast of New Jersey. At the surface, high 
pressure is over the Great Lakes extending southward to the 
Tennessee Valley. A Nor'easter is off the coast of New Jersey 
drifting westward slowly. Dry, sunny weather with pleasant 
temperatures will continue today and into Monday with highs mainly 
in the 70s (low 80s near Chattanooga).  

By Tuesday, the pattern starts to change with a weak ridge over the 
Southeast and a closed low over the Southwest. At the surface, weak 
high pressure is over or just off the coast of the Carolinas. A 
warming trend will become noticeable by Tuesday with highs in the 
80s for the rest of the workweek (90-91 degrees near Chattanooga). 
Dry weather will continue until low rain chances return on Friday. 
Higher rain chances will be possible on Saturday. The slow moving 
system to the west will move into the Midwest. A Gulf Low moving 
into the Southeast along with a ridge centered just east of Florida 
may bring increasing moisture into the region for next weekend, if 
that occurs we may see high rain chances next weekend.
