DISCUSSION

Issued at 217 AM CDT Wed Aug 19 2026

Showers and thunderstorms continue along a diffuse warm frontal boundary stretching from Oskaloosa, KS southeast through Pilot Grove, MO. Upper level instability and ample DCAPE still promote an environment for storms with damaging winds and some hail. As of writing, storms are progressing just enough to mitigate most flooding concerns. There is still some concern for hydrological impacts as radar QPE show around 1.5 to 2 inches of rainfall across portions of Atchison (KS) and Leavenworth counties progress eastward into the KC metro. Storms continue to gradually sink southward with showers and thunderstorms lingering through the morning hours; ending by midday.

Upper level flow pivots to the northwest which help usher a mid level shortwave southward. This brings additional opportunities for showers and thunderstorms later this afternoon into the evening hours primarily for areas north of the MO River. Ample instability and shear do present a marginal opportunity for a strong to severe storm; however, we will have a much better idea once this current complex roles through. Another cooler airmass moves in behind this front but all it does is delay the warming trend that arrives later this week as broadscale ridging begins to slowly build into the central CONUS. The center of this ridge stalls across the Rockies putting our CWA in the NW flow of the eastern hemisphere of the synoptic ridge. This opens up flow to allow multiple shortwaves to pass over the region presenting further opportunities for precipitation later in the week. Long term guidance slowly slides this high to the east suggesting the potential for another stretch of hot and humid conditions next week.

RA and TSRA continues for the next couple of hours across the terminals. Gusty winds across the south side of these storms continue affecting IXD. Additional development behind the initial line of storms keeps RA/TSRA around through much of the overnight. VFR conditions return during the morning and look to persist through much of the day. Additional TSRA is possible north of the MO River during the late afternoon/early evening; however, some uncertainties remain with RA forecast. Winds become light and variable after sunset.
