905 FXUS63 KTOP 212048 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 248 PM CST Fri Nov 21 2025 .KEY MESSAGES... -Scattered rain showers continue into this evening before tapering off tonight. -The weekend starts off dry and warm before another system brings rain back to the region. -Cooler weather moves into the area next week, precip chances continue to trend down during that timeframe. && .DISCUSSION... Issued at 245 PM CST Fri Nov 21 2025 Today`s rainfall is associated with a passing mid-level shortwave trough axis and surface low moving through southeastern KS this afternoon. Many locations have received between 1.0 and 2.0 inches of moisture since yesterday evening, with a new daily rainfall record set at KTOP. Scattered showers will continue to occur northwest of the surface low as it moves through southern MO and further east of the area this evening. Forecast soundings show drier air starting to advect into the region as lift decreases while a ridge axis builds overhead tonight. Areas of fog could develop late tonight and early Saturday due to a combination of soggy ground conditions, clearing skies and light winds. The early portion of the weekend will feature drier weather, sunshine and temps warming to near 60 degrees as a ridge axis becomes established aloft over the south-central US. Further west, a large cutoff low near Baja California will eject northeast over the CO Rockies by Sunday evening. Southerly flow ahead of that system will advect more moisture into the region with pwats increasing to around 1.0 inch. A few hundred J/kg of MUCAPE could also develop as a surface low deepens just west of the forecast area. POPs begin to increase from west to east Sunday night with 60-80% chances for rain and maybe an embedded thunderstorm on Monday. The LREF Grand Ensemble shows mean rainfall totals around a quarter of an inch, and only a 10% chance of half an inch or more. Dry weather returns Tuesday while a northern stream trough axis quickly follows the weakening Baja system through the Upper Midwest. That will bring a cold front through northeast KS, followed by much cooler weather by midweek. Trends for precipitation late in the week continue to decrease, with confidence increasing in a cold but dry Thanksgiving forecast. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... Issued at 1130 AM CST Fri Nov 21 2025 Rain showers remain around airports this afternoon before drier air and less lift decreases chances for precip by this evening. The challenge then becomes fog potential overnight and early Saturday as clouds begin to lift and scatter toward the pre-dawn hours. Have included IFR visibilities for the potential of early morning fog. Any fog that forms is likely to be shallow given expected drier air just above the sfc. Light north winds tonight become westerly, but remain less than 10 kts into midday Saturday. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Teefey AVIATION...Teefey
