KEY MESSAGES

Updated at 957 AM CST Mon Feb 16 2026

- A significant warming trend will take place for much of the week, as high temperatures will peak in the 60s and 70s each day through Friday. Overnight lows will remain well above the freezing mark.

- Medium chances for showers and low chances for a few thunderstorms will return to the forecast Thursday night into Friday.

NEAR TERM

(Tonight) Issued at 206 PM CST Mon Feb 16 2026

A beautiful afternoon across the Tennessee Valley, with high pressure in control of our sensible weather. This has promoted sunny conditions -- with afternoon highs reaching the upper 60s in most locations across the area. The clear sky will carry over to the evening hours across the Tennessee Valley. However, after Midnight model soundings are hinting at the development of low stratus which will carry over into the morning hours on Tuesday. These clouds will help to limit cooling and keep low temperatures from falling below the mid to upper 40s.

SHORT TERM

(Tuesday through Wednesday night) Issued at 957 AM CST Mon Feb 16 2026

Zonal flow aloft will prevail through mid week, with some passing cloud cover creating more partly to even mostly cloudy conditions both Tuesday and Wednesday. Despite these clouds, southerly flow will help to maintain this warm air mass, with highs reaching the upper 60s to lower 70s both days as a result. The dense cloud cover during the overnight hours will keep low temperatures extremely mild and in the 55 to 60 degree range.

LONG TERM

(Wednesday night through Sunday) Issued at 913 PM CST Sun Feb 15 2026

A nearly zonal upper flow pattern should be in place across the greater CONUS for the mid and latter portions of the week; albeit weak troughing west and weak ridging east. Upper level disturbances involved within the polar jet as they moves through weak troughing over the NE Pacific basin, are forecast to move over the Tennessee Valley after the midweek. In addition to a feed of upper level moisture, a deep southerly flow will bring additional lower-level Gulf of America moisture to the region.

The above will produce a more unsettled pattern for the late week. As such, lower end chances of showers returns to the forecast before daybreak Thursday. Heightened instability and modest shear will also bring isolated to scattered thunderstorms within more prevalent showers late Thursday into early Saturday. An overall flat upper pattern now depicted could help tame overall storm strength, if that trend continues. Later model runs should give a better picture of system details as we draw nearer to the late week.

Unseasonably mild to warm conditions are expected on Thursday, with highs rising into the mid/upper 70s and the mid 70s Friday. Lows Wednesday and Thursday night should range in the mid 50s to around 60.The extended models and blends show a cold front moving across the Valley on Friday. High pressure building in from Alaska/Canada will bring colder conditions to the area for the upcoming weekend and early next week. At the moment, highs on Saturday should range in the mid 60s, and the mid 50s Sunday. Lows will drop to around 40 Saturday night and into the upper 20s to near 30 Sunday morning.

AVIATION

(18Z TAFS) Issued at 1043 AM CST Mon Feb 16 2026

VFR conditions will prevail for the remainder of the day and evening underneath a clear sky. Guidance indicates some low stratus will develop after Midnight, promoting MVFR conditions with ceilings around 2.5 kft. After sunrise, these ceilings will rise to low-end VFR levels, with light southerly winds under 10 kts.
