023 FXUS63 KTOP 102306 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 606 PM CDT Fri Oct 10 2025 .KEY MESSAGES... - Patchy fog may form early Saturday morning mainly over east-central Kansas areas and along low-lying river valley areas. - Warm through the weekend and windy out of the south especially on Sunday. - Cooler into next week with the best rain chances on Monday ranging from 30-40% across the area. - Warming again by the end of next week as another trough digs into the western states. && .DISCUSSION... Issued at 241 PM CDT Fri Oct 10 2025 Across the CONUS this afternoon a pronounced ridge remains in place through the southern Plains into the northern Plains. An upper low and associated trough is translating across the Great Lakes region with another deep upper low and associated trough moving onshore into the Pacific northwest region. A modified cold front has shifted just south of the local area with associated low clouds along the front also south and southeast of the area. A few afternoon showers have begun to form along the boundary to the south along with the heating of the day. For this evening into the overnight period, temperatures still holding above seasonal norms with afternoon highs into the low 80s. As the surface ridge continues to expand overnight, dewpoints fall into the 50s. Expecting high clouds to spill over the ridge into the overnight period, but there may be a long enough window of radiational cooling over far eastern areas to allow for patchy fog to form by around sunrise. Fog over western areas may be harder to come by and would likely be limited to low-lying areas if it does begin to form as clouds continue to move in from the west. Overnight lows in the 50s still hold above seasonal normals. Good concensus remains in the short-term regarding the ridge flattening and shifting east through the weekend and breaking down as the western trough moves east and lifts into the northern Plains helping to push a cold front into the area by Sunday night into Monday. Ahead of the frontal system, expect highs to push 90 by Sunday with a strong south wind aided by mixing down the LLJ winds by mid to late morning into the afternoon as a lee trough deepens through the weekend. Monday, the best chances for rain comes into the morning and through the early afternoon periods. Ensemble data still suggests that overall rainfall amounts remain low generally under total accumulations of around a half inch over any one location. After the front moves through it stalls after becoming detached from the upper flow and returns by mid to late week as a warm front as another western trough digs into the intermountain-West. Temperatures rebound again above seasonal norms as an active pattern remains in place with position and timing of any additional showers and storms forming in question with more spread among various ensemble data. && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/...
