212 FXUS63 KICT 171140 AFDICT Area Forecast Discussion National Weather Service Wichita KS 640 AM CDT Tue Jun 17 2025 .KEY MESSAGES... - Severe storms likely this morning and again this afternoon/evening - Storms may linger into the daytime hours Wednesday - Dry and warm Thursday-Sunday with rain chances returning early next week && .DISCUSSION... Issued at 241 AM CDT Tue Jun 17 2025 As of 2 AM Tuesday morning, an intense complex of thunderstorms were progressing southward from north-central KS. Several reports of 60- 80 mph wind gusts have been observed. This complex is expected to continue propagating southeastward on the nose of the LLJ and the area of greatest low-level moisture transport. DCAPE values exceeding 1000 J/kg will allow the threat for damaging winds to continue into central/south-central KS. Transitioning into this afternoon and tonight, the ongoing MCS will progress southeast and ultimately dissipate. There remains some uncertainty with the amount of destabilization that will occur this afternoon. With the very moist boundary layer and surface heating, it seems plausible that destabilization will occur ahead of the main surface trough. The latest 00Z runs have shifted southward with the position of the effective front/outflow boundary. Confidence is greatest for the redevelopment of surface based instability generally south of Highway 50. The expectation is for upslope flow across southern KS into eastern CO will allow for storm development this afternoon. Rapid upscale growth is expected across eastern CO/western KS with the forward propagation of an intense MCS across the southern half of KS. The chief concern with this complex is wind gusts near 80 mph. An additional area of strong to severe thunderstorm development is expected along the main synoptic front near I-70. It`s uncertain whether surface based instability will recover in time for surface based storms. Should surface based convection develop after 3-4 PM, all hazards are possible including large hail, damaging winds, and tornadoes. This frontal zone will be slow to move southward. Storm motions are likely to parallel the boundary and will support training of convection. Short range ensemble guidance suggests additional amounts of 1-3" with locally higher amounts likely. Given all of the concerns above, have hoisted a Flood Watch for the entire through midday Wednesday. Lingering storms are possible across southeast KS Wednesday morning into Wednesday afternoon. Longwave, midlevel ridging will build across the area for the second half of the week, setting the stage for drier and warmer conditions. && .AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/... Issued at 639 AM CDT Tue Jun 17 2025 The main aviation concern over the next 24 hours is the potential for multiple rounds of strong to severe thunderstorms. Widespread convection remains across central and south-central KS. This will continue through much of the morning. Additional development is expected this afternoon into the evening and overnight hours. Finally, wind speed and direction may become VRB in the afternoon along I-70 with the main frontal zone stalling very near each terminal. && .ICT WATCHES/WARNINGS/ADVISORIES... Flood Watch through Wednesday afternoon for KSZ032-033-047>053- 067>072-082-083-091>096-098>100. && $$ DISCUSSION...BRF AVIATION...BRF
