912 FXUS63 KTOP 092019 AFDTOP Area Forecast Discussion National Weather Service Topeka KS 219 PM CST Tue Dec 9 2025 .KEY MESSAGES... -Strong northwest winds develop behind a cold front tonight. Gusts to near 45 mph are possible in far northeast KS. -Temperatures fluctuate from above normal to below normal and back again through the end of the week. -The weekend looks much colder, but snow stays north of the area. && .DISCUSSION... Issued at 216 PM CST Tue Dec 9 2025 Today, a clipper system is moving across the northern high plains while northwest flow persists aloft. Temperatures have warmed well into the 50s and low 60s across the area this afternoon with breezy southwest winds and WAA. Tonight, a cold front associated with the low to our north will quickly work through northeast KS. Northwest winds behind the boundary will increase to near wind advisory criteria (gusts of 40 to 45 mph), especially in far northeast KS. There has not been great agreement between HREF, LREF and NBM in meeting/exceeding criteria. HREF is the more confident solution in exceeding 45 mph gusts, and have noticed that the 90th percentile of NBM has increased slightly. But for now, have held off issuing an advisory with confidence not quiet high enough. Later shifts will re- evaluate and may need to consider at least adding far northeast KS to the advisory issued by neighboring offices. A few of the high resolution models also show light QPF near the front this evening and tonight. However, forecast soundings show a 5kft layer of dry air beneath the cloud deck, so any precip is likely to evaporate before reaching the ground. Surface high pressure builds in tomorrow so temperatures will be closer to normal in the mid 40s for highs. Gusty winds will decrease during the afternoon as the low moves further east, away from the region. The forecast remains dry through the rest of the workweek with another in a series of clipper systems staying north and east of the CWA on Thursday. Southerly winds return on Thursday, allowing temperatures to warm back into the mid 50s and low 60s. The next cold front moves through with that second clipper system Thursday night. High pressure will control our conditions through the weekend, keeping temps cooler than average, especially by Sunday when a reinforcing round of cold weather moves in. Lows Sunday morning could be in the single digits with highs Sunday afternoon only in the 20s. Another batch of snow again stays north of the area this weekend. && .AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/... Issued at 1138 AM CST Tue Dec 9 2025 Wind is the main aviation hazard this period. Breezy southwest winds will occur this afternoon ahead of a cold front that is expected to shift winds to the northwest tonight. A period of LLWS is expected along and behind the boundary as a 50 kt LLJ moves overhead. Surface winds will then increase again early Wednesday with gusts to 30 kts possible through Wednesday morning. && .TOP WATCHES/WARNINGS/ADVISORIES... None. && $$ DISCUSSION...Teefey AVIATION...Teefey
