Extended the wind advisory to northeast Tennessee and central Tennessee valley and extended until 4 pm. Given the latest observations and REFS showing winds remaining windy through much of the day decided to make the changes.

DISCUSSION

Issued at 1228 AM EST Mon Dec 29 2025

Currently a strong cold front charging through the region brining with it a quick round of showers and enhanced wind gusts right along the front edge. Winds have already been gusty this evening and while this line of showers is expected to weaken as it moves through Middle Tennessee it still could cause some enhancement of the lower atmospheric winds diving towards the surface. There is no lightning in this line, but we could definitely see some additional outdoor furniture blown around. QPF amounts still are expected to be light with the line also expected to waken

Still have a Wind Advisory in effect overnight for the Plateau, southwest Virginia, and the eastern Tennessee mountains with the common denominator being these counties have some of the higher elevation in the region and are reporting the highest wind gusts. All surface observations are indicating that the Wind Advisory is working out well, with no current plans to upgrade to a High Wind Warning.

Breezy conditions will continue even after sunrise with gusts slowly starting to come down throughout the day. Expect winds to back off below advisory criteria in the plateau and southwest Virginia in the late morning hours, but continue in the eastern Tennessee Mountains until closer to sunset.

Also of note will be the much colder temperatures behind the front, with lows in the morning likely dropping into the 30's, and below freezing at elevations above 2,000 feet. Coldest temperatures of the week continue for a few days as chilly air funnels in from the north/northwest through the middle of the week. With lows in the 20s and teens for the higher terrain forecast and some winds persisting for the higher terrain as well, wind chills near 0 will be possible.

High temperatures will rebound 10 degrees or so from Tuesday into Wednesday. A weak system will approach from the north Thursday into Friday, bringing a chance of light precipitation, with best chances across the northern part of the forecast area. By next weekend, precipitation chances increase from the south as the front stalls to our south. Where this sets up may determine how much precipitation we see. The southern valley and SW NC could sure use some beneficial rain to remove some of the moderate drought.
