KEY MESSAGES

Issued at 233 PM CST Fri Nov 13 2026

- Enough cold air will seep into South Arkansas for frost development and a Freeze Warning in effect into Saturday morning.

- Next week will begin cold and wet with the next chance of rain on Sunday/Monday most likely producing 0.5-1.25 inch rainfall totals by the middle of the week.

- A gradual warm-up returns by the middle of next week, pushing temperature maximums/minimums back to near seasonable lower 70s/lower 40s, respectively.

DISCUSSION

Issued at 233 PM CST Fri Nov 13 2026

Cold air advection continues to gradually wane with light northeasterly winds fading in strength across the Four State Region. Overnight temperatures (combined with clearing skies) will favor a brief window for maximized radiational cooling, especially for the Ouachita River Valley with near-freezing temperatures likely. Aloft, longwave troughing will slowly pull away through the weekend towards the Atlantic Ocean. Simultaneously, troughing across the Intermountain West will influence the development of lee cyclogenesis for the mid-level trough to shift across the Southern Great Plains into the lower Mississippi River Valley with our main rain chance in the next 7 days. WPC Day 1-7 QPF totals remain in the 1-1.5 inch range, with better rainfall totals west of I-49.

Medium range guidance suggests ridging that redevelops and builds behind the mid-level trough by the middle of next week. The flatter ridging that will return sets up a southwesterly flow pattern, supporting a gradual warm-up in temperature maximums/minimums back to near seasonable lower 70s/lower 40s, respectively. Long range guidance suggests gradual moistening of the atmosphere by the end of next week, with rain chances to be better resolved in future forecasts. /16/

AVIATION

(00Z TAFS) Issued at 642 PM CST Fri Nov 13 2026

For the 14/00Z TAF period, VFR conditions will prevail as high cirrus increases from the west this evening through the overnight hours. Some mid-level altocu will also gradually increase through the day on Saturday as the moisture profile aloft becomes more saturated ahead of an ejecting trough across the Desert Southwest. Light N/NE winds overnight will gradually increase through the day on Saturday, averaging between 6-12 kts with slightly higher gusts possible.
