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).
