Discussion

Issued at 103 PM EDT Thu Oct 29 2026

For the next few days, the pleasant fall weather will continue. A mid/upper level shortwave ridge will be crossing the region through Friday, with a low level ridge over the Appalachians. The main concern each day will be early morning fog, primarily near area lakes and rivers.

The upper ridge shifts east and a shortwave trough approaches from the west on Sunday. Moisture and lift will be mainly in the mid and upper levels, while the sub-850 mb layer remains dry for the eastern half of the area. Some light rain will likely reach the ground in the Plateau and southern TN Valley, maybe a tenth to a quarter inch, but NE sections will probably only see a trace to a couple hundredths through Sunday night. Overcast mid/high clouds on Sunday will hold high temperatures back in the 60s in most spots.

Dry and mild conditions return Monday and continue through at least Tuesday, possibly Wednesday. Another stronger system may bring higher rain chances to the area late Wednesday and Thursday. The ECMWF shows a deep, negatively tilted trough crossing the Plains and MS Valley in this time frame. One thing to keep an eye on with this system will be mountain wave winds, mainly Wednesday night.

Aviation

(18Z TAFS) Issued at 103 PM EDT Thu Oct 29 2026

Not much has changed in the weather pattern over the past few days, so fog will be possible again at CHA and TRI tonight. There is a chance that high clouds spreading over the area may reduce fog potential tonight, which raises uncertainty. For now, will include a TEMPO at both sites for a little MVFR fog, but lower conditions are certainly possible with later TAF issuances.
