.DISCUSSION... Issued at 239 AM CDT Mon Sep 22 2025
Areas of fog were already developing in southeast Kansas shortly after midnight. Fog is expected to expand across all of southeast Kansas and much of south central Kansas before mixing out during the early to mid-morning hours.
Shortwave ridging is progged to translate eastward over the Central Plains today ahead of a robust mid/upper trough digging into the Rockies. We expect much if not all of the area to remain capped to deep moist convection during the day today. As we move into the evening and overnight hours, low pressure at the sfc is progged to move eastward across northern OK with low level mass convergence allowing dewpoints to pool across southern KS. Showers and storms developing over the Central High Plains will propagate into our forecast area as trough emerges from the Rockies toward Tuesday morning. We continue to see steep mid-lvl lapse rates/sufficient elevated cape and deep layer shear to support some storm organization with a damaging wind and large hail threat after 07-08Z possibly lingering into the morning hours on Tuesday. Anomalous moisture is progged to linger over the area with PWATs progged in the 150-175 percent of normal range late tonight into Tue morning leading to efficient rainfall once again. With multiple rounds of storms and some clustering of storms, locally heavy rain could lead to some flooding or flash flooding. HREF neighborhood probabilities for exceeding 1 inch are high (~70%) with some 30% probabilities for exceeding 2 inches in parts of south central Kansas.
Another round of showers and storms are expected as the mid/upper trough moves across the area Tue night into early Wed before precipitation ends from west to east late Wed as the system exits into the Middle Mississippi Valley area.
Thu-Sun...A mid/upper ridge is progged to gradually build eastward into the central CONUS through the period. This will bring mild and dry conditions to the region from late in the week through the upcoming weekend.

Widespread dense fog was impacting parts of south central and much of southeast Kansas this morning. Visibility is being reduced to 1/4 mile or less at times.

An approaching storm system will bring increasing chances for showers and thunderstorms to the area after midnight. Storm activity may not impact KCNU until the end of the TAF period while our central KS TAF sites will be impacted around or shortly after midnight. Some of the storms late tonight and early on Tuesday could be severe with large hail and damaging winds.
