DISCUSSION

Issued at 1119 PM CDT Fri Oct 23 2026

Tonight through Saturday...

Southerly winds remained breezy over northeast Nebraska this evening, with speeds of 12 to 20 mph, gusting up to 20 to 30 mph. A few showers may sneak into far northeast Nebraska Saturday morning, ahead of an approaching upper level shortwave and surface cold front.

We could still see a brief lull in precip during the late morning/early afternoon hours, before additional showers develop behind the passing cold front. Overall, rainfall is expected to remain confined to locations northwest of a line from Columbus, to West Point, to Mapleton, IA. Temperatures will vary widely from northwest to southeast Saturday. Highs will range from the low 60s in the rain behind the front across northeast Nebraska, to the upper 70s under sunnier skies in southeast Nebraska/southwest Iowa.

Sunday into Monday...

Rain chances continue for the northwestern half of the forecast area Sunday and into Monday, as the remnants of an upper level trough eject northeastward through the Central Plains. By Monday evening, locations west of a line from Columbus to Sioux City have a 50-80% chance of seeing over an inch of rainfall. Meanwhile, Lincoln to Omaha, and areas to the southeast will be lucky to see 0.10" (<25% chance).

Temperatures continue to range widely from cloudy rain-soaked northeast Nebraska in the 50s and low 60s, to mid and upper 70s under southerly return flow in southeast NE/southwest IA.

Tuesday and Beyond...

Most locations should see a break in rain chances during the day on Tuesday, before the next trough moves from the intermountain west into the Dakotas. Highs on Tuesday look to be a bit more seasonable for the entire forecast area, with highs in the upper 50s and 60s.

Model solutions continue to diverge as we head into midweek. Chances for rain appear to be increasing for late Tuesday into Wednesday. However the forecast for Thursday and beyond is torn between the wetter GFS and notably drier ECMWF.

AVIATION /12Z TAFS THROUGH 12Z SUNDAY/

Issued at 524 AM CDT Sat Oct 24 2026

VFR conditions persist at the terminals through the TAF period.

KOFK: LLWS remains possible this morning, with conditions easing up by mid-morning. A line of showers with a few isolated thunderstorms has set up between Crofton and Cedar Rapids (NE) early this morning. On its current trajectory, the bulk of the line should stay to the west of the terminal; however, the leading edge of the line may clip the terminal or come close to it. A cold front will move into the region today, bringing a shift of southerly winds to the north. Expect ceilings to lower to around 4500ft as the front comes through. A few additional showers may be possible this evening into tonight.

KOMA/KLNK: VFR conditions prevail through the period. A cold front sliding across the region today will shift southerly winds to the northwest by mid-afternoon. Ceilings are expected to lower to around 10000ft later this morning. There is a chance for rain across portions of northern Nebraska today, but this should stay just to the west and northwest of the terminals.
