KEY MESSAGES

Updated at 837 PM CST Fri Nov 13 2026

- Freeze Warning issued for all of northern AL Saturday morning and Sunday morning for temperatures below freezing.

NEAR TERM

(Today) Issued at 210 AM CST Sat Nov 14 2026

Northerly flow continues to advect colder and drier air into the region this morning. Lower clouds continue to hug the Cumberland Plateau, keeping temperatures in the upper 30s to lower 40s in these locations. Subsidence has cleared the clouds further west in middle TN into northwest AL, allowing temperatures to dip quickly into the lower 30s in these areas. The forecast trend is for the remainder of the clouds to scatter or clear over the next several hours. A sunny and cool day is ahead again with highs in the lower to middle 50s in valley areas, and upper 40s atop the Cumberland Plateau. High pressure over the upper Midwest will slide into the lower OH and middle MS Valley today.

SHORT TERM

(Saturday night through Monday) Issued at 837 PM CST Fri Nov 13 2026

Another good setup for radiational cooling Saturday night in this cool, dry air mass as temperatures should drop like a rock underneath a clear sky. As a result, a widespread hard, killing freeze is expected with lows in the mid to upper 20s being common. Another Freeze Warning is in effect Saturday night into early Sunday morning. This widespread freeze should be enough to end our Autumn Frost-Freeze program. High pressure will build in from the north early next week, resulting in mostly sunny and tranquil weather both Sunday and Monday. Despite the sunshine though, temperature will remain on the cool side with highs in the mid to upper 50s being common both days.

LONG TERM

(Monday night through Friday) Issued at 837 PM CST Fri Nov 13 2026

At the start of the new work week, a cut off low will be plunging through the southeast. The low looks to pass to our south on Monday, before dampening and dissolving into the larger scale troughing over Florida on Tuesday. We currently look to be too far north of this feature to see any significant impacts beyond just some increased cloud cover.

By Tuesday afternoon, mid level ridging will begin to build in from the southwest, accompanied by surface high pressure building over the Ohio Valley. Through the remainder of the week, subsidence from high pressure will work to keep skies dry and clear. Under mostly clear skies, temps will enter a weak warming patter rising from highs in the low 60s to start the week to the low 70s by Friday. Low will follow a similar rebound warming from the 30s on Monday night to the mid 40s by Thursday night.

VFR flight weather conditions are forecast at KMSL and KHSV. However, patchy ceilings of 015-025agl (MVFR) will occur through 14Z in southern middle TN and far northeast AL.
