259 FXUS63 KICT 171742 AFDICT Area Forecast Discussion National Weather Service Wichita KS 1242 PM CDT Mon Aug 17 2026 ...Updated Aviation Discussion... .KEY MESSAGES... - Cooler temperatures will continue today before a brief warm- up on Tuesday followed by near normal temperatures for the rest of the week. - Slight rain chances are possible Tuesday night with better rain chances across the area for Wednesday night. && .DISCUSSION... Issued at 315 AM CDT Mon Aug 17 2026 Currently, the forecast area sits under upper level zonal flow as an elongated ridge extends across the southern tier of the CONUS and broad troughing digs into the northern US. At the surface, a weak low pressure sits over the Great Lakes with an associated frontal boundary draped across the Middle Mississippi Valley and over Oklahoma. Elevated PWATs (1.75-2") linger along and just north of the boundary across the southern portion of Kansas. Marginal instability, in conjunction with the moisture and boundary, has lead to the development of convection across the TX/OK Panhandles during the overnight hours. Some of this activity may manage to propagate eastward along the boundary and axis of moisture into south-central Kansas, but impacts would be minimal as instability and shear are lacking. For the most part, activity looks to fester along the boundary over the OK Panhandle and KS/OK border through the early morning hours before diminishing. Drier air will begin to filter into the region through the rest of today with widespread highs in the upper 80s and 90s for the forecast area this afternoon. Then by Tuesday, the trough across Canada will push southward and ridging will begin to build back in over the Plains from the west. We will see temperatures respond accordingly with upper 90s and lower 100s expected areawide on Tuesday. The widespread heat will be short-lived as the strengthening trough digs into the Great Lakes region, dragging an associated frontal boundary through the Northern Plains and into Nebraska. This feature will lead to rain and storms impacting northern Kansas and just clipping the forecast area. The frontal boundary will slowly pass across the state on Wednesday, leading to quite the temperature difference from north to south. Locations in central Kansas will see highs on Wednesday in the upper 80s while spots along the KS/OK border will top out in the lower 100s. More widespread chances for rain/storms across the forecast area develops Wednesday night as another shortwave dips across the Central Plains into a modestly moist airmass, though severe weather looks unlikely with this scenario. Seasonably mild temperatures behind the front, along with a drier air mass, are then expected for Thu/Fri. For the tail end of the forecast period, models are suggesting we may see the ridge try to build back in over the region from the west. Currently maintaining seasonably warm temperatures for the upcoming weekend with highs in the mid-upper 90s, but this trend could lead to more widespread heat moving into next week. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1237 PM CDT Mon Aug 17 2026 VFR conditions expected to prevail over the next 24 hours. VFR cigs should gradually exit southern and southeast Kansas this afternoon, and mostly clear skies should dominate the region this evening through Tuesday morning. Surface winds are generally under 10 knots and variable this afternoon. Winds should gradually shift to southerly or southeasterly this evening into tonight, then winds should increase to around 10 to 15 knots Tuesday morning. && .ICT WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...AMD AVIATION...JC
