336 FXUS63 KTOP 051107 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 507 AM CST Fri Dec 5 2025 .KEY MESSAGES... - More seasonable temperatures today and tomorrow before another brief cold spell arrives for Sunday. - Still very low rain chance Saturday evening across northeast KS, but otherwise no significant precipitation chances. && .DISCUSSION... Issued at 327 AM CST Fri Dec 5 2025 We continue to see broad upper troughing across much of the CONUS, while a ridge axis is centered off the West Coast. This pattern will persist throughout the next week. As a result, northwest flow will be maintained over the Plains, with multiple fast-moving, low- amplitude shortwaves moving through this flow. Right now, southerly flow has returned behind our most recent system. This will help temperatures moderate back to near average today. A weakening cold front moves through this evening but has little impact on temperatures Saturday. By Saturday evening, the next shortwave will move across the Midwest, with a surface low moving across southern Nebraska. This track will keep most precipitation to our north, though can`t completely rule out some brief rain across northeast Kansas. The main impact though will be a stronger cold front pushing through the area, making Sunday another day where temperatures struggle to get back to freezing. We`ll see a brief warmup next week as shortwave ridging builds in ahead of the next trough. The track of the 850 mb low will be favorable for a surge of warmer air with downsloping off the Rockies, giving good confidence in temperatures rising into the 50s Tuesday. Behind this system, we should see a return of cooler temperatures for the second half of the week. Exactly how cool is a question though, as ensemble spread quickly increases with the re-deepening of the eastern CONUS trough. && .AVIATION /12Z TAFS THROUGH 12Z SATURDAY/... Issued at 506 AM CST Fri Dec 5 2025 Some IFR stratus is currently beginning to develop in far south-central KS and move northward, but a majority of model guidance keeps it well south of the main TAF sites this morning, so will maintain a VFR forecast. Winds stay southwesterly around 5-10 kts today before weakening below 5 kts overnight. Towards the very end of the period Saturday morning, could see some patchy fog begin to develop, but confidence in this is very low for now. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Reese AVIATION...Reese
