237 FXUS63 KTOP 140554 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 1254 AM CDT Fri Aug 14 2026 .KEY MESSAGES... - Heat indices reaching 100 to 115 this afternoon with slightly cooler conditions each day through Monday. Excessive Heat Warning for most locations through Friday afternoon. - Storm chances build late this afternoon into this evening in western and northern areas with a few severe wind-producing storms possible. Small severe storm risks again late Friday and late Saturday. && .DISCUSSION... Issued at 244 PM CDT Thu Aug 13 2026 Another MCS traversing locations to the north pushed another outflow boundary across the area early today but most locations again have quickly recovered with early afternoon temps in the 90s and dewpoints in the lower 70s. Objective analysis shows modest surface low pressure over west-central Kansas which will nudge east over the next several hours. Convergence near the low and diminishing CIN should allow for at least isolated storms to form in central Kansas and spread northeast in the southwest flow aloft. Shear remains somewhat weak but MLCAPE and DCAPE would support severe downburst winds into the early evening with a decent low-level jet giving some support as well. Chances for additional showers and storms remain in the forecast into the weekend along and behind the front and any outflow. Severe weather potential is a little more nebulous but decent mid-level flow and moderate instability will bring some concern for stronger storms, mainly in the late afternoon and evening with better MLCAPE and DCAPE develop. Small storm chances return in the middle to late part of next week as southerly low- level flow returns under zonal flow aloft. Heat indices are in the triple digits most places at 19Z and today could bring the highest such values of this stretch. Over the next few days, outflow and synoptic boundary locations should slowly push south through the area for slowly cooling conditions. Confidence in neither Advisory-level heat in the north Friday nor in the remainder of the area Saturday to extended the Warnings is not high enough for any headline changes at this point. It`s not impossible for elevated heat to linger into Sunday if a drier/slower front works out. Monday and Tuesday still look the coolest though EPS 850mb temperature anomalies point to some warming again Wednesday and Thursday. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1247 AM CDT Fri Aug 14 2026 Will keep mention of thunderstorms around MHK for the first few hours of the period as storms are slow to move to the northeast. Current thinking is these should track away from the TOP/FOE terminals, but will continue to monitor for any development further to the east. Otherwise, winds should pick up from the south mid to late morning and may become lighter and more variable towards the early evening hours Friday along a weak boundary. Additional scattered showers and storms may accompany this, but chances are too low to add mention in TAFs at this time. && .TOP WATCHES/WARNINGS/ADVISORIES... Extreme Heat Warning until 7 PM CDT this evening for KSZ020-KSZ021- KSZ022-KSZ023-KSZ024-KSZ026-KSZ034-KSZ035-KSZ036-KSZ037-KSZ038- KSZ039-KSZ040-KSZ054-KSZ055-KSZ056-KSZ058-KSZ059. && $$ DISCUSSION...Poage AVIATION...Picha
