KEY MESSAGES

Updated at 1031 AM CST Sun Nov 15 2026

- Dry conditions and below normal temperatures are expected to continue today. Highs should climb to near or above normal (lower 60s) temperatures by Tuesday into the mid- week timeframe.

NEAR TERM

(Rest of Today and Tonight) Issued at 1031 AM CST Sun Nov 15 2026

Northerly flow continues to keep cold air advection in place over the Tennessee Valley this morning. Based on widespread low temperatures in the 25 to 29 degree range in many areas, a hard freeze was likely reached in most areas. After the cold start this morning temperatures have climbed to between 45 and 50 degrees. Some very high cloud cover is seen in satellite imagery extending from extreme NE Arkansas southeast into NW Alabama. This cloud cover is very thin and should not affect insolation much at all. As mentioned earlier, weak cold air advection in place will continue through the day. This should keep highs from topping out much above the 55 to 60 degree range in most locations. Looks like mixing of dewpoints in the afternoon is a moderate to high likelihood. This could drop RH values later this afternoon to between 28 and 32 percent in some locations. NNE winds of 5 to 10 mph are expected this afternoon.

Most guidance sinks the center of the surface high ESE this afternoon into the evening hours. This should keep a tighter pressure gradient south of the area. Thus, light winds are expected again tonight in most locations. The exception may be higher elevations east of the I-65 corridor. Lows will likely drop to or below freezing again in many locations (except in higher elevations). In higher elevations, lows may remain in the lower to mid 30s.

SHORT TERM

(Monday through Wednesday) Issued at 1031 AM CST Sun Nov 15 2026

The large surface high shifts east during the day on Monday. With easterly flow around the high, some low level moisture advection from off the Atlantic coast may occur. This should bump up dewpoints a bit in the morning on Monday. However, forecast soundings still show the potential for mixing of drier air down to the surface in the afternoon. Thus, lowered dewpoints below NBM guidance package much close to the CONSRAW. With less cloud cover expected and very weak warm air advection beginning to develop, highs should be warmer reaching the lower 60s again in many locations. Another frosty night looks to be in store Monday night despite some low level increase in moisture advection. Lows in the lower to mid 30s look fairly widespread still.

As the surface high remains in place near the Mid-Atlantic region into the middle of this week, the upper ridge continues to amplify. This amplification coupled with abundant sunshine and strengthening warm air advection will continue to push temperatures higher during the day. Highs on Tuesday should climb to near normal values (60 to 65 degrees). Lows will slowly warm into the mid 30s to lower 40s as well.

LONG TERM

(Wednesday night through Sunday) Issued at 1031 AM CST Sun Nov 15 2026

An incoming upper level trough will swing through the Central and Northern Plains on Wednesday, and tries (but does not succeed) to break down the upper ridge over the southeast. At the same time, an upper level low becomes cut off and anchored over the Florida peninsula.

The cut-off low will keep our upper level 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 the lower 70s 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.

AVIATION

(18Z TAFS) Issued at 1136 AM CST Sun Nov 15 2026

Surface high pressure over the upper MS Valley will control the sensible weather through Mon morning. NE winds around 5kt should continue for the TAF. Passing high altitude clouds will shift south of the area in the overnight, with clear skies expected on Mon.
