KEY MESSAGES

- Severe thunderstorm chances remain overnight in the southern tiers of counties of the forecast area. Damaging wind, hail, and heavy rain will be the primary threats.

- Training storms could produce heavy rainfall and flash flooding in far southeast Nebraska/southwest Iowa overnight.

- Near-normal temperatures are expected next week with little to no additional chances for precipitation forecast.

LONGER TERM

The remainder of the forecast stays relatively quiet with little to no chance at additional spring precipitation over the next seven days. The southwest flow at H5 will veer and come out of the northwest as general trofing moves through the central CONUS mid-week. The NBM has introduced 25% PoPs on Thursday with a cold front sweeping through.

Tuesday morning and Wednesday morning may both bring patchy frost to far northeast Nebraska, especially in low lying areas as winds are expected to decouple overnight.

AVIATION /06Z TAFS THROUGH 06Z TUESDAY/

Issued at 1210 AM CDT Mon Apr 27 2026

A mix of VFR and MVFR cigs across eastern Nebraska tonight with IFR/LIFR cigs and vis looming to our west behind the cold front. Low cigs will expand eastward, bringing MVFR or IFR cigs to all the terminals over the next few hours. We'll see showers and thunderstorms move into eastern overnight, with greater coverage down toward KLNK and KOMA. Winds will shift to northerly as a cold front moves through later this morning, becoming fairly strong gusting to 30 kt by the afternoon. As the front moves through expect cigs to either drop to IFR or hold at MVFR into the afternoon with cigs gradually lifting through the afternoon into the evening.
