KEY MESSAGES

Updated at 816 PM CST Sat Nov 14 2026

- Freeze Warning continues for all of Northern Alabama late tonight through 8 AM Sunday morning for low temperatures below freezing.

NEAR TERM

(Rest of tonight and Sunday) Issued at 816 PM CST Sat Nov 14 2026

SFC high pressure continues to be in control of the local weather with clear skies and light winds expected across the Tennessee Valley tonight. Temperatures have begun to drop into the upper 30s where winds have gone calm to lower 40s elsewhere. The NBM continues to be the coldest of the ensemble blends with overnight lows between 25-31F, but some newer HIRES guidance such as the HRRR, RRFS, and REFS are a few degrees warmer keeping most of the area between 30-33F by daybreak tomorrow. If winds do go calm across the area, then expect the colder end of the guidance, but if winds remain light then temperatures across the area should get near or just below freezing. Regardless, there is still high confidence that a large portion of the local forecast area will see sub-freezing temps tonight, therefore the Freeze Warning goes into effect starting at midnight and continues into Sunday morning. However, confidence is much lower in a hard freeze, which is temperatures below 28F.

On Sunday, the deep upper level trough axis across the eastern CONUS will push off to the east and flatten out a bit. At the same time, ridging to our west begins to amplify and shift into the central Plains. Compared to the last few days, CAA is much weaker with a more northwesterly flow aloft. Therefore, expect afternoon highs to warm up a few more degrees into the mid to upper 50s, which is still 5-10 degrees below climatological normals for this time of year.

SHORT TERM

(Sunday night through Tuesday night) Issued at 816 PM CST Sat Nov 14 2026

Clear skies and light winds will once again provide ideal radiational cooling conditions on Sunday night. Temperatures are forecast to drop into the upper 20s across portions of southern middle TN and lower 30s across northern AL. A frost or freeze product may be needed for our AL counties if the forecast holds, but for now will hold off given the uncertainty of below freezing temperatures. A gradual warming trend will occur during the start of the work week as the sfc high shifts to the east bringing more easterly flow to the Tennessee Valley. Expect afternoon highs to rise into the low to mid 60s on Monday and Tuesday. Overnight lows will dip once again into the upper 20s to lower 30s. Additional frost and freeze products may be needed as we head into next week.

LONG TERM

(Wednesday through Saturday) Issued at 816 PM CST Sat Nov 14 2026

The ridge that expands from the Southern Plains up through the Midwest on Tuesday will get squished for the lack of a better description through the week and into the weekend. An incoming upper level trough will swing through the Central and Northern Plains on Wednesday, and tries to shove the ridge eastward. The ridge instead will moreso lean eastward onto the an upper level low that is cut off and anchored over FL and the Southeast Coast. The cut off low will keep our upper level winds northeasterly and sfc winds mainly easterly through Thursday, reducing the true potential of how much we could warm up. Friday, the southwesterly winds aloft ahead of the trough to the north will give a slight push to temps though. Regardless, with the strength of the ridge, we will have slightly warmer than normal temps, reaching the mid/upper 60s on Wednesday, with a few of us reaching 70 on Thursday and all of us in the 70s Friday and Saturday. Overnight lows will be above freezing through the extended, upper 30s/lower 40s, but still keep cold weather safety in mind.
