426 FXUS63 KTOP 250728 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 228 AM CDT Sun Oct 25 2026 .KEY MESSAGES... - Another warm and mostly dry day today before rain chances increase this evening across central Kansas. - Warm temperatures continue through the end of October with highs in the 70s and low 80s. - Low chances for rain (20-40%) will exist on most days this week but not expecting much in terms of rainfall amounts. && .DISCUSSION... Issued at 228 AM CDT Sun Oct 25 2026 The central US continues to remain under the influence of the large upper level cyclone situated across the desert southwest. Further north, the main jet stream connects two upper lows; one across the PNW and the other approaching the Hudson Bay. Back across the central Plains, mid and upper level moisture continues to stream northeast ahead of the main trough axis as compact upper-level ridging keeps the region warm. With WAA within this pattern expected to continue today, high temperatures will again creep back into the upper 70s and low 80s as broken decks of mid and high clouds stream in across Kansas. By late this afternoon and evening, the surface cyclone and inverted trough deepens across central Kansas in response to the eastward progression of the upper cyclone. This should shift a good focal point of low-level isentropic ascent and mid-level ascent across central and north-central Kansas. Rain chances will be expected within a narrow corridor into Monday morning across central and north-central KS with chances quickly waning as one heads east of Hwy 81. Most areas stay dry Monday with the exception of areas near the Hwy 81 corridor. Scattered precipitation chances (20-30%) do not seem to shift into eastern Kansas until Tuesday morning as the upper-level cyclone finally ejects off the central Rockies and across Nebraska. A weak cold front slides across the area Tuesday yielding low-end PoPs (20-40%) and slightly cooler afternoon temps (low to mid 70s). By Wednesday and the remainder of the week, temperatures are expected to rebound back into the upper 70s and low 80s as southwesterly flow sets up across much of the western and central CONUS. Several nodes of vorticity embedded in the flow will move across the region keeping low-end PoPs in the forecast for the remainder of October. That said, not expecting much in terms of copious amounts of rainfall. && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/... Issued at 1147 PM CDT Sat Oct 24 2026 VFR TAFs continue over the period at all sites. A weak boundary may shifts winds around at KMHK through the early morning hours Saturday but southerly flow should return by late Sunday morning. Mid to high clouds continue to filter in from the southwest with some rain chances approaching KMHK by the late period. Best confidence in precipitation remains west of KMHK so kept out mention at this time. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Griesemer AVIATION...Griesemer
