208 FXUS63 KICT 272244 AFDICT Area Forecast Discussion National Weather Service Wichita KS 544 PM CDT Wed Aug 27 2025 .KEY MESSAGES... - Well-below normal temperatures continuing into this weekend and early next week. - Shower and storm chances increasing tonight through Thursday with heavy rainfall and flooding as the main concerns. && .DISCUSSION... Issued at 246 PM CDT Wed Aug 27 2025 Currently, there is an expansive surface high pressure covering eastern Kansas with low pressure in eastern Colorado. Ongoing showers and storms in central to south-central Kansas will shift east into the evening affecting eastern to southeast Kansas where a broad area of low-level WAA persists. Tonight, showers and storms are expected to increase in coverage and intensity. A strengthening low-level jet will set up in southern Kansas, leaving an axis of mid- level convergence from central KS to the Flint Hills. Additionally, an upper-level jet will move towards the Lower/Middle Mississippi Valley leaving our area in a zone of upper-level diffluence. These coupled together will lead to an area of heavy rainfall rates as PWATS are generally around 2". Generally between 500-1000 J/kg of MUCAPE is likely, making isolated occurrences of small hail possible especially with 30-40 kts of effective shear forecast. Storm motion is expected to be to the southeast along the axis of convergence of the low-level jet making training storms possible overnight. Ensembles continue to have >75% chance of most of the area seeing over 1" of rainfall with about a 75% chance that central KS through the Flint Hills into southeast KS observes more than 2". In some of these areas, there is a 15-30% chance of more than 4" mainly in the Flint Hills and southeast KS. The bulk of this precip is expected to fall overnight into Thursday morning. Some short range deterministic models such as the HRRR and RAP position the band of heavy rain farther south bringing the Wichita metro into the flooding threat, giving some uncertainty with exact positioning. Given the concern for heavy rainfall and flooding risks, a Flood Watch has been issued as rain totals are generally between 2-5" with locally higher amounts possible. By Thursday afternoon, showers and storms should shift south/southeast of our area. Given expansive cloud cover, high temperatures will remain in the low to mid 70s. Weak mid-level ridging will move in, allowing temperatures to slowly rise back into the mid to upper 70s on Friday. As we transition into the weekend, weak southerly/southeasterly flow should return at the surface helping temperatures to warm towards 80 on Saturday and Sunday. There is a chance for precip Saturday night into Sunday as a weak ripple moves into the Plains. The timing and location of this precip on Saturday night will need to be refined as we get closer. Precip chances may continue into early next week as northwesterly flow aloft persists with weak ripples riding the upper-level ridge. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 544 PM CDT Wed Aug 27 2025 Showers currently observed over the area will gradually expand in coverage later tonight, with thunderstorms possible as well. Heavy rainfall reducing visibilities is expected with the strongest activity. Still thinking the most likely corridor for impacts will lie primarily from SLN to CNU, though a slight shift to the south and west could take place depending on how low-level features set up. A mixture of MVFR and IFR ceilings currently observed over the area will gradually build in later this evening into tonight, with model guidance indicating high confidence in IFR ceilings potentially transitioning into LIFR later tonight especially in central KS. Stay tuned to upcoming cycles as additional information becomes available. && .ICT WATCHES/WARNINGS/ADVISORIES... Flood Watch through Thursday afternoon for KSZ048>053-067>072- 083-093>096-098>100. && $$ DISCUSSION...GC AVIATION...JWK
