KEY MESSAGES

Updated at 1038 PM CST Sun Dec 7 2025

- Medium/high (50-80%) chances for rain tonight into early Monday morning.

- Subfreezing temperatures return Monday night before a gradual warming trend through midweek.

- Confidence is increasing in the potential of very cold conditions by next weekend.

NEAR TERM

(Rest of tonight and Monday) Issued at 1038 PM CST Sun Dec 7 2025

A shortwave clipping the Tennessee Valley is bringing some medium/high chances for light rain showers (50-80%) overnight. Precipitation will be light, with QPF amounts being generally under one-quarter inch or less. The rain chances combined with the dense cloud cover will keep temperatures fairly steady overnight, with lows only dropping to the upper 30s to lower 40s. This quick hitting system will exit the area by daybreak. However, a stout inversion may make it tough for cloud cover to erode (long after rain tapers off) until the mid/late afternoon on Monday. As a result, temperatures won't budge much and it will feel like a very chilly day as temperatures will only reach the mid 40s.

SHORT TERM

(Monday night through Thursday) Issued at 1038 PM CST Sun Dec 7 2025

Dry conditions, with a gradual warming trend will occur Tuesday and Wednesday as high pressure at the surface builds into the region. Ample sunshine and surface winds gradually veering to the south will help to modify the cool, continental air mass somewhat. As a result, high temperatures will reach the low to mid 50s on Tuesday and the upper 50s on Wednesday (with a few locations possibility reaching the 60 degree mark). A shortwave trough will shift from the Ohio Valley into the Central Appalachians, forcing a weak front into portions of KY/TN. While this boundary will likely hang up north of the area, some cloud cover and some very low (10-20%) chances for light rain are forecast on Thursday as this shortwaves passes through the area. Amplification of a broad upper trough over the Great Lakes will eventually lead to additional shortwaves transversing the area and a much colder air mass moving in. More on this in the section below.

LONG TERM

(Thursday night through Sunday) Issued at 1038 PM CST Sun Dec 7 2025

A couple additional shortwaves will traverse the southern flank of a broad trough that will be amplifying over the eastern CONUS. These subtle shortwaves will bring reinforcing shots colder, drier air into the region. Highs on Friday will peak in the upper 40s to lower 50s, with overnight lows dropping into the lower 20s. Saturday and Sunday looks to be even chillier as high temperatures will struggle to climb above the 40 degree mark both days -- with overnight lows falling into the upper Teens to lower 20s both nights. Any winds at all will result in even lower wind chill values, especially Saturday night along the higher terrain. In summary below normal temperatures will be favored late this week into the very early part of next week which could favor temperatures at least 10-15 degrees below normal for mid December. Review your winter weather safety rules and prepare to bundle up!

AVIATION

(06Z TAFS) Issued at 1126 PM CST Sun Dec 7 2025

IFR conditions will prevail for much of the overnight hours due to low ceilings and reduced visibilities from -RA. Expect very minimal improvement until mid/late morning when ceilings are at least progged to rise above to climb above 1 kft. Cloud cover will continue to break up, but BKN decks of clouds between 2-3 kft (MVFR conditions) will prevail through the afternoon and evening hours. Winds will also become gusty out of the NW during the day on Monday before weakening to under 10 kts late in the day.
