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 /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 540 AM CDT Sat Sep 26 2026

IFR/MVFR ceilings persist across terminals early this morning, while showers have gradually come to an end resulting in VFR visibilities. Will see ceilings rise slowly to VFR throughout the day. There is a 30% chance for some more showers and storms to clip the KLNK and KOFK terminals after 15z and 00z respectively, but given the low probabilities have left mentions out. Late in the TAF cycle, will see fog overspread the KOFK terminal resulting in MVFR conditions. Winds remain at 12 kts or less from the southeast, becoming east northeast at the end of the TAF cycle.
