480 FXUS63 KOAX 261711 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1211 PM CDT Sat Sep 26 2026 .KEY MESSAGES... - Widespread rain with a few thunderstorms Saturday morning. Additional rain with a few thunderstorms develop Saturday evening. Rainfall totals of 1 to 2+ inches are expected. - A brief warmup into the 70s and drier weather on Sunday into Monday. - Rain and thunderstorms return Tuesday through Thursday with heavy rainfall. Flooding may be possible. && .DISCUSSION... Issued at 1107 PM CDT Fri Sep 25 2026 A broad upper-level trough over the central Rockies with several embedded disturbances continues to lift northeast towards our area. This is resulting in widespread showers and a few thunderstorms across eastern Kansas and eastern Nebraska. This rain will continue to lift northeast overnight into Saturday morning. It`ll be a soggy start to the weekend with 1 to 2 inches of rainfall for many. Temperatures hold steady in the 60s during this time. In the wake of the morning rain, a brief period of drier conditions may develop, though spotty showers could linger. Temperatures should warm into the upper 60s to perhaps low 70s by mid-afternoon. As we move through the afternoon and evening another round of rainfall is forecast. While the ascent from the upper-level trough will be positioned east of the area, lingering ascent under this disturbance should help with redevelopment. The best chance (50-70%) of showers and thunderstorms is expected across far eastern Nebraska and western Iowa heading into Saturday night into Sunday morning. While rain gradually shifts east through Sunday morning, patchy fog is likely to develop behind it. Fog should lift by Sunday afternoon as drier conditions return to the region. While it remains mostly cloudy, most locations should see 70s for highs by the afternoon. Dry weather largely continues into Monday with only a low chance of showers Monday morning. The clouds linger, but another dry afternoon in the 70s can be expected. The dry weather does not last long. The remnants of Polo will combine with an upper-level trough approaching the area heading into the work week. By early Tuesday morning, widespread showers and thunderstorms begin to push into the area once again. Periodic showers and thunderstorms may linger into much of the remainder of the week as this system will be slow moving. That said, uncertainty remains on how quickly this system progresses across the region. That said, with the abundance of recent rainfall, flash flooding and rises in area rivers may become an increasing concern. Outside the return of wet weather, cool temperatures in the 60s make a return as well. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1200 PM CDT Sat Sep 26 2026 Ceilings have mostly improved into the MVFR category with southern locations, including LNK, improving to VFR over the late morning hours. Precip will be scattered this afternoon, mostly along the Kansas state line. Chances are too low to include in TAF issuance (<40%). Most aerodromes will remain dry. Otherwise, primary concern will be the development of fog overnight. Expect IFR visibility at all locations with LIFR cigs forecast at KOFK. Have trended optimistically with the visibility forecast, expect to 50%+ chance of cigs slipping - at least temporarily - lower than forecast. Expect to see clearing to occur slowly on Sunday morning. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ DISCUSSION...Chehak AVIATION...Nicolaisen
