743 FXUS63 KICT 140816 AFDICT Area Forecast Discussion National Weather Service Wichita KS 316 AM CDT Sun Jul 14 2024 .KEY MESSAGES... - A smattering of hit-or-miss showers and thunderstorms through about mid this morning. - Hot above average temperatures through Monday. - A few storms possible Monday evening-night over central and north-central Kansas. - A return to cooler weather and off-and-on thunderstorm chances by late Tuesday, persisting through at least next weekend or early next week. && .DISCUSSION... Issued at 311 AM CDT Sun Jul 14 2024 Similar to the past few nights, a smattering of hit-or-miss showers/thunderstorms is expected through about mid-morning across portions of central, south-central, and southeast Kansas, due to persistent weak to modest mid-level warm advection underneath a subtle mid-upper disturbance approaching from the north. Available instability and effective shear is limited given how high based this activity is (around 12,000 ft AGL), so severe weather is not expected, although cannot rule out small hail, gusty winds, and brief heavy rain with the strongest cells. Otherwise, hot temperatures and breezy/gusty south winds will continue today and Monday. Will continue the heat advisory through Monday evening, as afternoon through early evening heat indices will exceed 100-105 degrees both days. A cold front approaching from the north should be a focus for isolated to widely scattered thunderstorms Monday evening-night, mainly over the northern half of Kansas. The main concern with this activity will be locally strong to severe wind gusts given high cloud bases. Per deterministic and ensemble consensus, a pattern change to cooler and off-an-on wet weather is anticipated by late Tuesday, and persisting through at least next weekend or early next week. The culprits will be longwave upper troughing becoming established across the central and eastern CONUS, driving a cold front south into Mid-America. The latest guidance suggests these off-and-on thunderstorm chances will be greatest late Tuesday through Wednesday evening, and then again Saturday through early next week. Periodic bouts of strong to severe storms are possible, given a favorable combination of buoyancy and deep layer shear. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1249 AM CDT Sun Jul 14 2024 Subtle mid-upper energy approaching from the north in concert with persistent modest 800-600mb warm advection should support a gradual uptick in widely scattered showers/thunderstorms by around 10z, persisting through mid-late this morning. Brief heavy rain and occasional lightning strikes may accompany the strongest activity. For now, only included VCSH at HUT-ICT-CNU, but may eventually need TS. Otherwise, breezy/gusty south winds will prevail regionwide today. && .ICT WATCHES/WARNINGS/ADVISORIES... Heat Advisory until 8 PM CDT Monday for KSZ032-033-047>053- 067>072-082-083-091>096-098>100. && $$ DISCUSSION...ADK AVIATION...ADK
