A flash flood watch is in effect from Saturday evening through Monday evening, according to the National Weather Service.
Showers and thunderstorms are expected to redevelop across the lower Missouri Valley this weekend as a series of upper-level disturbances move across the region, the weather service said.
These disturbances, combined with high amounts of atmospheric moisture, will lead to periods of moderate to locally heavy rainfall from Saturday night into early next week, according to the weather service.
Heavy rains combined with nearly saturated soils and elevated water levels on area rivers and streams will lead to possible flooding and flash flooding during the Memorial Day holiday weekend, the weather service said.
