Severe storms and flash flooding risk persist into Sunday; Father's Day remains warm with cooler week ahead.

Scattered severe storms are rolling through Nebraska Saturday night into Sunday, Father's Day, with a Slight Risk — Level 2 out of 5 — of severe weather still covering the entire state, according to KLKN TV. The biggest threat is flash flooding, with some areas seeing 3 to 5 inches of rain in localized pockets. A Flood Watch is in effect for south-central and southeast Nebraska until 7:00 a.m. CDT Sunday.
The storms are expected to clear by around 10:00 a.m. Sunday, opening the door to a dry and warm Father's Day afternoon. Highs will reach the 70s and 80s across the state, according to KLKN TV.
The National Weather Service office in Omaha warned that "repeated rounds of heavy rainfall are expected this evening into Sunday morning," with rain falling at rates above 1 inch per hour. That kind of steady, heavy rain on already-saturated ground is what drives flash floods. The Flood Watch covers south-central and southeast Nebraska and runs until 7:00 a.m. CDT on June 21.
Nebraska's Department of Transportation urged drivers to check Nebraska 511 before hitting the road. Jay Omar, the department's communications director, said: "With severe weather and wildfires impacting areas of Nebraska, we are reminding travelers to check Nebraska 511 before heading out." Emergency managers are pushing a simple message: turn around, don't drown.
Flooding is not the only risk tonight. The strongest storms could also produce brief spin-up tornadoes, ping-pong-ball-sized hail, and wind gusts up to 65 mph, according to KLKN TV. "Spin-up tornadoes" are quick, short-lived twisters that can form with little warning, especially at night when they are hard to see.
The Storm Prediction Center had earlier placed parts of the Central Plains under an Enhanced Risk — Level 3 of 5 — on Saturday. That threat level dropped to a Slight Risk as storms became more linear and rain-wrapped, shifting the primary danger from tornadoes to flooding.
Once the morning storms move out, Sunday afternoon looks much better. Temperatures will climb to the low-to-mid 70s in Omaha and Lincoln. Residents in the Fergus Falls and Jamestown areas to the north can expect quieting conditions overnight and pleasant weather for Father's Day, according to Fergus Falls Journal and Jamestown Sun.
Cooler, calmer weather is forecast to hold through the rest of the week. That stretch of mild late-June conditions is expected to continue across the region, offering a break after a turbulent stretch of storms.
This weekend's storms are the latest chapter in a brutal spring for Nebraska. Governor Jim Pillen approved a state emergency declaration for nine counties on June 10, estimating $5 million in damage from May storms alone. He also sent a separate $10 million wildfire damage request to the federal government. As of June 18, both requests were awaiting White House approval.
The agricultural toll is staggering. The USDA rated 84% of Nebraska's winter wheat crop as "Poor" or "Very Poor." The state's wheat harvest is forecast at just 16.2 million bushels — a 57% drop from 2025 levels. Even heavy rainfall this weekend may not be enough to end the "Extreme to Exceptional Drought" covering roughly half the state.
