KEY MESSAGES

Updated at 213 AM CST Wed Dec 3 2025

- Persistent low overcast will last into the morning hours. - Chances for rain occur at times Thursday through Saturday night, with medium to high chances Thursday night into Friday morning.

NEAR TERM

(Today) Issued at 213 AM CST Wed Dec 3 2025

Persistent low overcast remains in place over the Ohio and Tennessee Valleys south to the Gulf Coast. Surface high pressure was situated along this axis of cloud coverage and will shift east into the TN valley today. This will keep winds light and may tend to delay the dissipation of the clouds. The 00Z BMX and OHX soundings indicate a strong inversion associated with the layer of clouds as well which may also tend to keep them in play through most of today. For now, there is model support for dissipation of the cloud cover with time today. This would enable sunshine to push temperatures into the 40s to around 50 for highs this afternoon.

SHORT TERM

(Tonight through Saturday) Issued at 1056 PM CST Tue Dec 2 2025

Another storm system should begin forming Wednesday afternoon over the Texas coast. As a surface low with this system over the NW Gulf region develops, clouds from it will begin overspreading the Tennessee Valley during Wednesday night. Low temperatures should cool to around 30 with light winds. Rain from this system should begin overspreading some of the forecast area Thursday. Areas with the best rain chances should be near/south of the Tennessee River. High temperatures Thursday should rise into the mid/upper 40s.

As the system traverses the Thu night/Fri morning, more rain from the system should reach the area. This rain like with the last system should be more stratiform than convective in nature (being on the north side of the cyclone), thus any thunder occurrence is minimal. The better rain chances will be more to the south. With rain, not as cool Thursday night with lows in mid 30s (some lower 30s cannot be ruled out in southern middle Tennessee). Highs on Friday should rise into the mid/upper 40s and lows in the 30s. The newest NBM has went on a wetter track with rain chances as we close out the week. The system tracking slowly along the northern Gulf coast will keep chances of rain continuing into Saturday. Given the low being well to our south, the higher rain chances likewise will remain to our south. High temperatures Saturday should inch up a bit to around 50.

LONG TERM

(Saturday night through Tuesday) Issued at 1056 PM CST Tue Dec 2 2025

The main feature to watch through the long term forecast will be the passage of a 500 MB trough through the eastern CONUS. Through the weekend, the trough will amplify and move from the Plains into the eastern CONUS. In association a surface low pressure system looks to pass through the area from Sunday and Sunday night.

Deterministic models maintain high uncertainty regarding if any precip will be present with the frontal passage. As such, stuck with blended guidance that reflects the low chances of rain (~20%) from Sunday night. If we do receive precip, especially near daybreak Monday morning, we will have to keep an eye on temps as they will likely near or just below freezing which could produce brief and hopefully non-impactful wintry precip. We have very low confidence in this however, just an interesting (non-impactful) tidbit to keep an eye on.

Through the beginning of the work week, zonal flow aloft paired with high pressure influence will promote non impactful weather. Temps will have the opportunity to warm slightly with highs in the 40s and 50s. The forecast becomes slightly more uncertain from Wednesday forward as models struggle to resolve our next system.

AVIATION

(12Z TAFS) Issued at 441 AM CST Wed Dec 3 2025

Persistent low overcast event will continue through most of today with ceilings of 010-020agl (MVFR). A few patches may drop below 010agl (IFR) for a brief time as well. Uncertainty remains on whether the overcast layer will dissipate this afternoon, so check for future updates. This update will maintain clearing around 22Z with a return to VFR conditions.
