.SHORT TERM... (Tonight through Friday Night) Issued at 1050 PM CDT Wed Sep 24 2025
Showers and storms continue this evening with a focus in the northwest which is in the vicinity of an elongated, weak surface low ahead of the positive-tilted upper trough. The surface front will begin to move into the western portion of the area around dawn and progress eastward through the afternoon hours. Scattered showers and storms will continue to be possible even after the surface front moves through as the upper trough lags behind. The moisture doesn`t look as rich on Thursday compared to Tuesday and Wednesday. PWAT values will be in the 1.4-1.7" range. CAMs do show some pockets of 1- 2" rainfall totals through Thursday evening, but we should be able to handle this without any major flooding issues.
As the trough axis approaches the area, some energy will be cutoff and left behind. Where this happens is still a little uncertain. It will be close enough to the area to continue the low chance of showers for the plateau on Friday. Football games Friday night should not be a washout for those on the plateau as any showers around will decrease after sunset.

.LONG TERM... (Saturday through next Thursday) Issued at 1050 PM CDT Wed Sep 24 2025
The low rain chances will continue through the weekend as some upper level energy remains in the region. As we move into next week, eyes will be in the Atlantic as two potential tropical systems begin their northern track into the mid latitudes. Some of the moisture from the tropical systems might be bled into our eastern half of the area producing some low rain chances. Otherwise, once we get through Thursday evening, the majority of the area looks like it will be dry through the rest of the forecast. Conditions will be comfortable on Friday and Saturday with lows in the 50s and highs in the mid 70s to low 80s. As we get to Sunday and into next week, temperatures look to be a couple degrees above normal to end September with highs in the upper 70s to mid 80s.

.AVIATION... (00Z TAFS) Issued at 622 PM CDT Wed Sep 24 2025
Isolated showers are developing out ahead of what could be a second wave of rain with embedded thunderstorms. Instability is lacking this evening, so uncertainty remains if any storms will be able to develop. MVFR cigs are moving in from the west with a further category degradation to IFR overnight. A lift back to MVFR looks to occur sometime in the morning.
Winds remain southerly through tonight near 10 kts. A gradual wind shift will occur as the front approaches with winds eventually turning out of the NW near 18Z.
