KEY MESSAGES

Updated at 1044 AM 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

(Tonight) Issued at 258 PM CST Sat Nov 14 2026

Cold high pressure that built to the south from northern Canada over the past few days, was now positioned across the upper Mississippi Valley. Colder air from this ridge made for a chilly last night across the Tennessee Valley. Northerly lower level moisture advection has shifted more to our east, as slightly drier air filters in from the north and west. This and afternoon mixing has dropped dewpoints lower than most model guidance into the lower to mid 20s in a few locations. Temperatures with abundant sunshine have climbed into the 50 to 55 degree range in most areas. A few locations could still climb a degree or two higher before sunset, topping out in isolated locations in the 56 or 57 degree mark. NW to N winds continue between 5-10 mph. Normal highs this time of year are around 65 degrees.

Less overall moisture in the atmospheric column in shown in guidance tonight. This will help allow for more uninhibited longwave radiation from the surface - and colder temperatures. The aformentioned surface high will also be situated over the Central States, with the coldest air from it settling over the Valley. Some guidance does suggest that winds may stay up between 4 and 8 mph in higher elevations in NE Alabama. This may keep lows just slight warmer, but likely still to or around freezing into Sunday morning. Thus, low temperatures by Sunday morning should be at or below freezing in most places, with a widespread hard freeze (lows at or below 28 degrees) more common west of Jackson and Marshall counties. Therefore, a Freeze Warning will be active again from midnight tonight through 8 AM Sunday morning.

SHORT TERM

(Sunday through Monday) Issued at 1044 AM CST Sat Nov 14 2026

The surface high should begin shifting more to the east early next week, reaching the Mid Atlantic Mon into Tue. Another system now impacting the central and southern Rockies will move SE towards coastal TX/LA. Except for an increase in mid/high altitude clouds on Sunday from this system, no other impacts are expected for this region. Despite the clouds, milder conditions are expected Sun with highs rising into the mid/upper 60s.

Another chilly night is expected Sun night, as lows fall into the upper 20s to mid 30s. We are holding off on another Freeze Warning at this time, as freezing temperatures tonight maybe cold and widespread enough to officially end the growing season.

LONG TERM

(Tuesday night through Saturday) Issued at 258 PM CST Sat Nov 14 2026

Even milder temperatures are forecast to start a new work week, with highs into the lower 60s, as a large amplified upper ridge builds east over the area. Some very low RH values might be in store Tuesday into Wednesday afternoon, with highs climbing into the mid to upper 60s.

Though it modifies slightly towards the end of next week, an strong upper ridge remains in place and stronger southwesterly flow ahead of a more amplified longwave trough axis should help push temperatures a bit higher ito the end of next week. By Friday into Saturday highs should be back into the upper 60s/lower 70s at least given the strength of the upper ridge.

AVIATION

(18Z TAFS) Issued at 1122 AM CST Sat Nov 14 2026

VFR conditions are expected throughout the TAF period. N to NE winds between 5 and 10 knots are expected this afternoon before becoming light early this evening. At this time, it appears the airmass will be too dry for fog development, but will monitor the period around daybreak in subsequent shifts in case it is needed. Winds will pick up to around 5 knots and become more ENE on Sunday.
