.KEY MESSAGES...
- Severe thunderstorms are possible this afternoon and evening favoring areas south and east of Dodge City. Primary hazards are large hail and damaging wind gusts.
- Additional thunderstorms are possible Tuesday afternoon and evening, but low ensemble member agreement reduces confidence.
- Near-normal temperatures through Friday, followed by below- normal temperatures over the weekend.

.DISCUSSION... Issued at 200 AM CDT Mon Sep 8 2025
Early morning water vapor satellite imagery and RAP upper air analysis reveal a rather unremarkable synoptic pattern, with weak troughing east of the High Plains, and weak ridging to the west of the High Plains. At the surface, broad high pressure engulfs almost the entire eastern CONUS, while lee troughing is spread out along the front range of the Rockies. Given weak low-level warm advection and a shortwave impulse ejecting onto the central plains, some pre-sunrise showers and thunderstorms may develop favoring areas along and east of US-183, and continue into the late morning/early afternoon. This activity will likely be sub-severe, posing little to no threats. Thunderstorm outflow and convective cloud debris will impact the temperature forecast, as areas that see precipitation will enjoy another day of well-below normal highs in the upper 70s. Farther west, afternoon highs will steadily increase from the low 80s near US-283 to the low 90s along the KS/CO border. Another, more significant round of thunderstorms appears possible across our southeast zones, beginning after 22Z. While synoptic-scale forcing for ascent will be minimal, strong insolation will likely result in convective temperatures being achieved for areas south and east of Dodge City. 2000-3000 J/kg of SBCAPE and 35-40 kts of bulk shear will support a severe threat with this activity, with large hail and damaging wind gusts the primary threats. Convection should clear the KS/OK border by 01-02Z, and the remainder of the overnight period will be quiet with lows in the upper 50s/low 60s.
Daytime Tuesday, short range ensembles agree upper level ridging will advance eastward to over the High Plains as a strong longwave trough makes landfall on the west coast. As a result of increased subsidence atop the central plains, all zones will see an uptick in temperatures with afternoon highs rising into the upper 80s to low 90s. HREF members do suggest a varying degree of additional thunderstorms Tuesday afternoon and evening, but little to no agreement between them renders confidence low on the spatiotemporal details.
Wednesday through the end of the period, medium range ensembles agree the upper level ridge will gradually shift eastward as the strong upper low pushes from upstream. This trend supports continued near-normal temperatures through the end of the work week followed by below-normal temperatures over the weekend as the trough draws closer. Precipitation chances will be limited but not zero, with ensemble meteograms displaying the strongest signal Wednesday evening.

.AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1230 AM CDT Mon Sep 8 2025
VFR flying conditions this TAF cycle for all terminals, except for a few hours during the 09-14Z time frame when showers or weak thunderstorms potentially impact HYS, bringing MVFR cigs and vis. Otherwise, southerly winds will continue through 06Z Tuesday, following the typical trend of aoa 12 kts during the overnight and early morning hours, and sustained in the 15-20 kt range gusting to 30 kts during the late morning and afternoon.
