Omaha, on the Missouri River, receives around 780 mm (about 31 inches) of rain a year, with a clear summer peak from convective thunderstorms typical of the Great Plains, including a real risk of severe weather and tornadoes during the spring and early summer storm season. These storms can develop quickly over the flat surrounding farmland and bring large hail alongside intense, localized rainfall capable of flash flooding specific streets. The Missouri River itself has a more gradual flood pattern tied to snowmelt and sustained regional rain further upstream. Because the fast-developing local storms are the more immediate hazard, radar tracking during spring and summer is a genuinely practical tool. NWS Doppler radar KOAX (Omaha/Valley) covers the region.
