Rain this week in eastern Nebraska will make it even harder for areas to dry out from a seriously soggy spring.
In addition, continued runoff from rain could keep the Missouri River running high, which has already led to road closures in western Iowa and at bridges crossing the river.
In the 24 hours ending at 7 a.m. Tuesday, Omaha's Eppley Airfield reported .78 of an inch of rain. The Millard Airport reported 1.43 inches, Gretna reported 2.17 inches and Valley reported 1.52.
Wahoo had 1.28, Mead had 2.30 and Lincoln had 1.32 inches. Nemaha and Richardson Counties reported flash flooding overnight, said Becky Kern, a Valley-based meteorologist.
Tuesday is expected to be humid, with isolated thunderstorms around the area and highs close to 90. Some spots could see locally heavy downpours, but nothing widespread is expected, Kern said.
Through Friday night, another 3 inches of rain could fall across a wide swath of eastern Nebraska and western Iowa, forecasters said. The area will be stuck back in an active pattern of weather, which could mean a cycle of rain and scattered thunderstorms every 12 hours or so, said Scott Dergan, another Valley-based meteorologist.
Wednesday is expected to be dry, with highs in upper 80s. Showers and thunderstorms could return to the region Thursday, when highs in 80s are forecast. Showers and thunderstorms also could occur Friday. The chances for precipitation increase Saturday.
Storms could lead to rapidly rising streams and creeks on the local level, and won’t help current flooding on the Missouri.
The Missouri River, swollen by rain and increasing releases from upstream dams, is projected to rise to 31.6 feet in Omaha on Tuesday, just below moderate flood stage. The rain isn’t expected to lead to a dramatic increase in the river level, Dergan said.
Flooding and water on roadways has already closed Interstate 29 from northern Council Bluffs to Loveland, Iowa, and a southern stretch from U.S. Highway 34 near Glenwood to the Iowa-Missouri border.
Multiple Missouri River crossings between Omaha and St. Joseph, Missouri, are closed, including Interstate 680, which connects northern Omaha and Iowa and Nebraska and Iowa Highway 2 at Nebraska City. For up-to-date information on road closures, visit 511ia.org or 511.nebraska.gov
“Hopefully we can move this out of here by the time the (College World Series) starts,” Dergan said. The college baseball championship starts June 15.
