905 FXUS63 KICT 172334 AFDICT Area Forecast Discussion National Weather Service Wichita KS 634 PM CDT Tue Jun 17 2025 .KEY MESSAGES... - Severe storm and flooding potential through this evening. - Increasing heat/humidity late week and through the weekend. && .DISCUSSION... Issued at 322 PM CDT Tue Jun 17 2025 The main forecast concern is severe thunderstorm and flooding potential through this evening. Thunderstorm activity is currently ongoing generally along the Highway 56 corridor within a zone of strong 850-700mb warm advection and in vicinity of an old outflow boundary slowing sagging south. In the short-term this activity will pose a marginally severe hail/wind threat, along with very heavy rainfall and flooding concerns. As we head into the late afternoon and evening, we`re watching the potential for this current activity to gradually sink south- southeast and possibly strengthen as these storms encounter a more unstable environment amidst impressive vertical shear for mid-June standards. The best near-surface based instability and low-level convergence looks to be near the KS/OK border on south in vicinity of a stalled frontal zone, which could be the greatest potential for higher-end severe weather through the evening in the form of very large hail, damaging winds, and possibly a tornado or two, especially if an HP supercell or two can manage to develop ahead of the approaching upscale growth. However, activity currently approaching from the west-northwest could gradually strengthen as well as we head into early evening, as instability continues to increase amidst a favorable shear profile. The primary risks will be damaging winds and perhaps large hail, although given the impressive low-level shear north of the frontal zone can`t rule out a tornado or two, especially if the airmass can become rooted closer to the boundary layer. After this first round of thunderstorms pushes through late this afternoon and early evening, short-term guidance supports another round of storms coming moving in from the west-northwest early to mid-evening, with a continued threat for damaging winds and perhaps some large hail. Thinking the severe threat should exit southeast Kansas by around midnight. Additionally, given the rainfall last into early today, along with multiple rounds through this evening, areas of flash flooding and river flooding are likely, especially generally along and south of the Highway 56 corridor. Quiet weather looks to return Wednesday, with seasonable temperatures mostly in the 80s. As we head into late week and this weekend, building upper ridging will support increasing summer heat, with highs in the 90s to possibly near 100 degrees expected. Given the wet antecedent conditions, humidity will likely be an issue as well, increasing the potential for 100-105+ degree heat indices. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 631 PM CDT Tue Jun 17 2025 Main aviation concern will be storm chances tonight. Scattered strong/severe storms continue across much of south central and central KS. This should continue through at least the next few hours as 850-700mb theta-e advection remains in place. We should see an overall decrease in convection after 05-06z as the better moisture transport shifts east. Large hail and downburst winds will be the main threat with the stronger storms. && .ICT WATCHES/WARNINGS/ADVISORIES... Flood Watch through Wednesday afternoon for KSZ032-033-047>053- 067>072-082-083-091>096-098>100. && $$ DISCUSSION...ADK AVIATION...RBL
