298 FXUS63 KICT 210708 AFDICT Area Forecast Discussion National Weather Service Wichita KS 208 AM CDT Fri Aug 21 2026 .KEY MESSAGES... - Periodic thunderstorm chances through next week, mainly during the evening, night, morning hours. A handful of strong to severe thunderstorms possible. - Near to above average temperatures through next week. && .DISCUSSION... Issued at 202 AM CDT Fri Aug 21 2026 THUNDERSTORM CHANCES: Model consensus keeps a stout upper ridge anchored across the southern to southwest CONUS the next several days. This will keep the Kansas region within a northwest flow aloft pattern favorable for periodic thunderstorm chances, underneath a persistent mid-level thermal gradient. Unfortunately, predicting exactly when/where thunderstorms will form and track is extremely difficult in patterns like this, making for a low confidence forecast. Seasonable instability combined with modest deep layer shear (with a decent directional component given the NW flow aloft) will support periodic strong to severe storm chances. Thinking isolated to scattered thunderstorm chances will exist overnight into early this morning generally along/west of the Flint Hills. While a marginally severe storm capable of dime-quarter size hail can`t be ruled out given the decent deep layer effective shear, widespread severe weather looks unlikely. Another signal for scattered elevated thunderstorms exists from early this evening through tonight, as 800-600mb warm advection commences once again ahead of shortwave energy dropping southeast across the upper Midwest. Instability and directional shear combo will favor a few strong to severe thunderstorms. This activity could linger into early Saturday morning. Much of Saturday and Saturday evening look dry, with additional storm chances arriving from the northwest late Saturday night and Sunday. As mentioned earlier, these off-and-on thunderstorm chances look to continue much of next week. TEMPERATURES: With the stout upper ridge remaining anchored within fairly close proximity of the Kansas region, near to above average temperatures are expected through at least the next 7-10 days. Afternoon through early evening heat indices look to be in the 95 to 105 degree range, highest over south-central and southeast KS. Not anticipating any heat headline issuances on this shift. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1051 PM CDT Thu Aug 20 2026 VFR conditions are expected to prevail at all sites through the end of the period. East winds currently observed across the area will gradually develop turn to the south/southeast through the morning hours, though speeds in general should remain below 12 kts. Additionally, thunderstorms observed over portions of central KS will continue tracking south here tonight, though impacts to terminals should be relatively minimal. We continue to see the potential for more elevated showers and weak storms around or just before daybreak and lasting into the mid- morning hours. Currently thinking these will reside to the east of I- 135, though with coverage likely isolated in nature, decided to go without a mention at ICT with this issuance. Additional chances for showers and storms will return to portions of central KS later Friday evening, though confidence in location and timing is a bit too low for mentions at RSL/SLN at this time. && .ICT WATCHES/WARNINGS/ADVISORIES...None. && $$ DISCUSSION...ADK AVIATION...JWK
