890 FXUS63 KICT 201133 AFDICT Area Forecast Discussion National Weather Service Wichita KS 633 AM CDT Sun Jul 20 2025 .KEY MESSAGES... - Isolated showers and storms continue this morning across portions of central KS; additional storms possible along I-70 this afternoon/evening - A few storms possible tonight across central and south-central KS - Excessive Heat Warning remains in effect today through Wednesday && .DISCUSSION... Issued at 354 AM CDT Sun Jul 20 2025 As of 330 AM Sunday morning, zonal midlevel flow continues with the ridge axis across the southern MS valley. The most robust convection is ongoing on the nose a 30-35 kt LLJ across southern IA. Broad low/mid level WAA continues to produce weak showers/storms across portions of central KS. As the LLJ veers through sunrise, anticipate this activity to dissipate. The remnant surface trough axis, which has been reinforced by convective outflow extends from northeast KS through central KS and into west-central KS. A weak midlevel perturbation, which is currently within the central Rockies, is forecast to eject into WY/NE later today. This should result in isolated development along a dryline across portions of CO/WY/NE. While the strongest forcing for ascent is likely to remain north of the forecast area, sufficient convergence along the aforementioned surface trough may result in isolated thunderstorm development by late afternoon in the vicinity of I-70. A deeply mixed boundary layer, characterized by dew depressions near 40 degrees, will result in inverted-V profiles. As such, any storm will be capable of wind gusts near 60 mph. This zone of convective potential should dissipate with sunset. In regards to extreme heat, heat indices up to 110 degrees are expected area-wide this afternoon. Refer to the Extreme Heat Warning for additional details. Additional WAA driven showers/storms may emerge into the overnight hours across central and south-central KS. Severe weather is not expected with this activity. For Monday and beyond, the midlevel ridge will amplify across the central/southern MS valley. A stagnant airmass is expected with daytime highs in the upper 90s/near 100 degrees. Otherwise, the nocturnal LLJ is expected across central/south-central KS each night and could result in isolated storm development, especially towards sunrise each morning. A weak cold front will approach the area by late week and may provide some relief from the hot temperatures. && .AVIATION /12Z TAFS THROUGH 12Z MONDAY/... Issued at 630 AM CDT Sun Jul 20 2025 VFR conditions are expected through the period. A weak surface trough in the vicinity of RSL and GBD will keep winds mostly light and variable throughout the period. Elsewhere, southerly winds will increase to 10-15 kt with gusts near 20 kt. Finally, a PROB30 group was added at SLN and RSL this afternoon for the potential for isolated storm development. This potential could expand to GBD, HUT, and ICT but confidence remains too low for those sites for now. && .ICT WATCHES/WARNINGS/ADVISORIES... Extreme Heat Warning until 7 PM CDT Wednesday for KSZ032-033- 047>053-067>072-082-083-091>096-098>100. && $$ DISCUSSION...BRF AVIATION...BRF
