Issued at 1233 PM EDT Tue Sep 9 2025
Key Messages:
1. Mostly clear and dry conditions continue with high pressure in
control.
2. Gradual warming trend into the weekend. Beautiful early
September weather.
3. Low isolated to scattered rain chances begin to show up in the
forecast for the mountains early next week as low-level moisture
increases and weak troughing sets up across the Appalachians and
East Coast.
Discussion:
We remain dry and mostly clear through the end of the week with
high pressure in control of our weather. Winds remain light and
patchy valley fog, especially near lakes and river valleys, will
be expected most mornings. Fog will dissipate each day by around
10 AM.
The weekend forecast continues to be dry although temperatures
will begin to warm as upper-level ridging builds in across the
Mississippi and Tennessee Valleys. Dry weather forecast for all of
the outdoor events late this week and weekend across the region.
Low-level moisture begins to increase early next week with 10 to
20 percent probabilities of a shower across the higher elevations.
Most areas remain dry with no measurable rainfall during the next
7 days.
