859 FXUS63 KICT 301839 AFDICT Area Forecast Discussion National Weather Service Wichita KS 139 PM CDT Sat May 30 2026 .KEY MESSAGES... - Spotty rain/storms linger in eastern Kansas this afternoon. - Severe storms likely today, developing in south-central Kansas this afternoon and progressing east through the evening. - Isolated severe storms possible Sunday afternoon, mainly east of I-135. - Seasonal temperatures over the next week with highs in the 80s to around 90. && .DISCUSSION... Issued at 134 PM CDT Sat May 30 2026 Currently, a shortwave trough is situated over the Central Rockies with a larger trough extending across the Canadian and Northwest US Pacific Coast. Weak ridging is positioned just to our south across the Southern Plains. In the mid-levels, WAA continues across the region and the overnight LLJ is beginning to weaken to our southwest. At the surface, a low pressure has developed and sits over the Central High Plains. Sub-severe showers and thunderstorms dot eastern Kansas. This activity will gradually push east out of the area over the next few hours. As we move through this afternoon and evening, the western trough will lift into the High Plains and the surface low in the lee of the Rockies will begin to shift further east into western Kansas, pushing a sharpening dryline from western into central Kansas during the afternoon into evening hours. Ample instability (3500-4500 J/kg MLCAPE) and shear of around 30 kts will make the most of a relatively uncapped environment leading to widespread strong to severe storms. Storms look to initially develop along the dryline across central Kansas as a few discrete cells after 3pm. Because of the weak cap, once we see convective initiation, we will see a cascade effect of storms unzipping along a line in central Kansas. Due to the lack of deep shear, discrete supercellular structure will not be supported and the convection will evolve into a broken line that will quickly move east-northeast. Strong winds of 70-80 mph and large hail up to tennis ball sized would be the primary threats with the strongest storms, though a brief tornado or two cannot be ruled out. As the upper level and lee surface trough slowly move over the High Plains into Sunday morning, a few widely scattered showers could linger, especially over northern and eastern portions of the forecast area through the morning hours. Then for Sunday afternoon, a dryline will once again develop across central Kansas that could initiate afternoon and evening convection once again. Confidence remains low as the ridge to the south begins to build in over the region, leading to increasing heights and weakening overall ascent over the region. Decent instability and sufficient shear would support isolated storms should they manage to develop. Current guidance indicates development along and east of I-135 with activity pushing east through the night. Then for next week, a mid/upper level ridge will continue to build in over the region with the forecast area remaining just north of the ridge axis. This will lead to not only increasing temps (middle 80s to lower 90s), but an overall less supportive environment for more potent convection due to synoptic scale subsidence. However, due to the positioning of the upper-level flow, and given the buoyant lower-level airmass, some diurnally driven showers and storms look to develop each afternoon/evening. Confidence remains low on exact location and intensity of any convection for Sunday afternoon through Thursday. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1235 PM CDT Sat May 30 2026 A band of showers and thunderstorms continues to shift to the northeast across the Flint Hills and southeast Kansas. This activity may miss CNU to the north and south hence only PROB30s have been included at this time but the activity could produce gusty and erratic winds as well as drops in visibility due to heavy rainfall. Additional showers and thunderstorms are expected to develop across central and south central Kansas this afternoon and then spread to the northeast this evening and impact most of the TAF sites. These storms will be more potent, with the potential for large hail, damaging downburst winds, frequent lightning, and heavy rainfall. Activity should shift east and north of the TAF sites around sunset although a few lingering showers and thunderstorms may continue through late tonight. Low clouds and fog will try to develop early tomorrow morning which could lead to some IFR to LIFR ceilings and visibility. Confidence on seeing this activity is highest across central Kansas but may also impact ICT and HUT as well. VFR conditions will return by late tomorrow morning to all sites. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...AMD AVIATION...WI
