Area Forecast Discussion National Weather Service Wichita KS Issued by National Weather Service Topeka KS 1226 PM CDT Tue Jun 3 2025 .KEY MESSAGES... - Scattered to numerous showers/storms through this evening. A handful of strong to severe thunderstorms are possible, along with areas of heavy rainfall and increased flooding concerns, mainly along and east-southeast of the KS Turnpike. - Additional off-and-on shower/storm chances late Wednesday night through the weekend, although uncertainty remains high surrounding finer details. && .DISCUSSION... Issued at 320 AM CDT Tue Jun 3 2025 TODAY THROUGH THIS EVENING: Scattered to numerous showers/thunderstorms will continue across the region today through this evening, as a potent upper low approaches from the southwest, and a strong cold front moves in from the northwest, amidst a moist and weakly/uncapped airmass. Isolated instances of marginally severe storms are possible this morning, but thinking greater chances will hold off until early afternoon and persist through the evening, mainly along and east-southeast of the KS Turnpike, as instability increases ahead of the approaching cold front. The combination of modest to strong instability and weak to modest deep layer shear should support mostly a damaging wind threat (60-70 mph winds) with the strongest activity, although could see isolated instances of large hail (likely no larger than half-dollars) due to the magnitude of buoyancy. Any hail threat would likely be earlier in the event before numerous cell mergers encourages mostly upscale growth. Additionally, the strong forcing in conjunction with anomalously high precipitable waters and mid/upper flow nearly parallel to the frontal zone will also support areas of heavy rainfall and localized flooding concerns, mainly this afternoon-evening from roughly the KS Turnpike on east-southeast. 1-3 inch rainfall amounts are expected, with locally higher amounts possible. Widespread extreme rainfall amounts (e.g. greater than 3-4 inches) are unlikely though given the relatively fast-moving nature of the cold front. Nevertheless, since soils are still fairly saturated from recent heavy rainfall, rises in rivers/streams are likely, with the greatest potential for river/stream levels reaching or exceeding flood stage over southeast Kansas. The flood watch currently in place looks good, with no plans of expanding at this time. LATE WEDNESDAY NIGHT THROUGH THE WEEKEND: Deterministic and ensemble consensus continues to support a low-predictability pattern setting up by mid to late week through the weekend, with off-and-on chances for showers and thunderstorms across the region. The culprits will be various low-amplitude shortwaves interacting with a wobbly frontal zone across the region, amidst anomalously high precipitable waters. A seasonable combination of instability and deep layer shear will support off-and-on severe weather chances, with the anomalous PWs supporting locally heavy rainfall and potential flooding concerns. Stay tuned as we continue to refine forecast details in the coming days. TEMPERATURES: A rather significant cool down is expected from northwest to southeast today in wake of the strong cold front, with temperatures likely falling into the 50s and 60s behind the front. Below average temperatures will continue Wednesday, with daytime highs in the 70s likely. A slow warm up back closer to average is expected through late week and into next weekend, with off-and-on chances for showers/storms likely preventing widespread above average temperatures. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1225 PM CDT Tue Jun 3 2025 Scattered thunderstorms along and south of a cold front will continue to impact locations in south-central Kansas through the afternoon hours leading to brief IFR conditions. Low ceilings and gusty winds will linger behind the front. Winds will diminish generally after 00Z with ceilings beginning to lift shortly thereafter. VFR conditions are expected areawide, with the exception of CNU, after 08-09Z. && .ICT WATCHES/WARNINGS/ADVISORIES...
