.DISCUSSION...
Issued at 1255 AM EDT Fri Oct 10 2025
In the upper levels, a shortwave is lingering over the Southeast as
a cut-off low moves into the Great Lakes Region. A strong ridge
remains over the Great Plains and Rockies. At the surface, high
pressure centered over New England extends all the way to Texas.
High pressure moves out quickly tonight as the Great Lakes system
moves southward and low pressure develops along the east coast
strengthening over the Mid-Atlantic. The ridge will finally build
into the Tennessee Valley early next week. Our region will remain
dry on the backside of the East Coast system with northwesterly
flow in the upper levels.
Dry weather is expected this weekend through mid next week. A
gradual warming trend is expected early next week as the ridge
builds into the region but temps will still be pleasant with highs
mainly in the upper 70s.
