KEY MESSAGES

- Cooler and dry weather is likely into early next week.

- After seasonable warmup this week, another round of cooler temperatures and potential patchy frost and lows near freezing possible again into next weekend.

DISCUSSION

Issued at 1245 PM CST Sat Nov 7 2026

Through Sunday...

GOES East water vapor and visible satellite indicate the cold core upper low is now centered just east of Lake Erie with a trough axis down into the Appalachians. A second upper low resides over the Baja California into Desert Southwest. Cooler and drier air will continue to dominate this pattern locally in the wake of a recent dry, reinforcing cold front. Increased isentropic ascent and cirrus now reside over much of the area with mid to high level cloudiness persisting through the weekend. 1025 mb surface high will build in late weekend into the Mid South, bringing much cooler temperatures through tomorrow (low to mid 70s F highs for Sunday). Seasonable lows are expected this weekend with lows 33 F to 43 F tonight and Sunday night. Patchy frost is possible this weekend as winds become calm Sunday night and effective radiational cooling becomes more likely. The dry soil conditions will support overachieving of the nocturnal cooling processes. At the same time, there remains potential for cirrus cloud decks to stubbornly stick around this weekend downstream of the SW US upper low, which could keep temperatures from dropping as much as they would in clear sky conditions. Putting these factors together yields uncertainty for low temperatures and potential frost impacts. Regardless, frost potential remains a concern, especially in low-lying and sheltered areas. Ensure plants are covered or indoors and consideration for pets and people cold temperatures with frost to light freeze potential persists. Kept inherited Limited HWO graphic with minimal adjustments for patchy frost during these nights, mainly in north-central, east to northeast MS.

Through next week...

Quiet, cloudy and mostly dry pattern will persist into next week. Moist, isentropic ascent and cloudy conditions will remain draped across the Gulf Coast states through at least mid week (Wednesday). Isolated rain shower is possible around midweek, but probs remain isolated and low (less than 15 percent). Upper low is still projected to become open shortwave, ascent will be less prominent as it propagates eastward. With some thermal temps warming, highs will moderate to seasonably through mid week (69 F to 77 F Monday to 73 F to 79 F by Wednesday). Lows will remain seasonable. The synoptic pattern will feature a brief shortwave ridge passage early week before the eastern half of the country becomes dominated by deep layer troughing. With limited airmass recovery in the boundary layer likely under this suppressed regime, a drier and cooler pattern into late week continues to look likely. This could include another round of patchy frost or light freeze in the day 6-8 range. Winds generally will be light through much of the period but clear days with full sun and associated deep mixing with little rain in sight could result in increased wildfire danger by Friday. /DC/EC/86/
