.KEY MESSAGES... Issued at 230 PM CDT Fri Sep 12 2025
- Late summer heat will extend into this weekend and much of next week with high temperatures averaging the lower to middle 90s.
- Persistent upper-level ridging in place will continue to drive the heat and also suppress rain chances through next week.
- Drought and fire weather concerns may begin crop up with a more prolonged period of heat and dry conditions later this month.

.DISCUSSION... Issued at 230 PM CDT Fri Sep 12 2025
With dominant high pressure at the sfc and aloft, we`ve still managed to derive a few very isolated showers near Toledo Bend this afternoon, likely the result of weak differential heating. Otherwise, it`s a continuation of this stagnant late summer heat pattern courtesy of a stubborn upper-level ridge that remains anchored across much of the southern and central U.S. Therefore, persistence is the name of the forecast game through this weekend with high temperatures still climbing into the lower and middle 90s while lows will range from the upper 60s to mid 70s with some patchy fog possible once again in isolated locations.
As this persistent pattern carries into the new work week, soil moisture will become further depleted throughout this period of extended heat and dryness. Although fire weather conditions are not particularly concerning right now, this could become more problematic if a pattern change doesn`t materialize later on this month. Fortunately, there are subtle signs that ridge may begin to slightly weaken as we progress from mid to late next week. This is the first real indication of some possible relief in the offing by the end of next week with an upper-level trough and accompanying cold front spilling south from the Plains and Midwest by Thursday into Friday.

.AVIATION... (18Z TAFS) Issued at 1236 PM CDT Fri Sep 12 2025
For the 12/18z TAFs...A scattered cu field is developing across the region and will continue into the afternoon. Short-range guidance has cloud cover decreasing through the day, with a few higher level clouds being the only coverage for much of the overnight hours. The same guidance has cloud cover increasing towards the end of the period with some moisture advection. But I`ve kept the forecast to the typical cu field development for now due to uncertainty. Winds will generally stay light/variable through the period.
