Nebraska precipitation forecasts for February-April (Figure 3) and March-May (Figure 4) are more worrisome. Below normal moisture should cover the southern and central Plains region, extending north to include much of Nebraska. This scenario would suggest that the northern Plains dryness is not likely to disappear until April or later. Nebraska climate data also suggests drier than normal moisture (less than 50% of normal) in February and March.
It also suggests that the eastern Cornbelt will remain wet and flooding and/or planting delays likely will occur this spring in the Ohio and mid-Mississippi River valleys. Closer to home, the current snow pack is rated normal to below normal in the headwater region of the Platte and Missouri watersheds because most of the recent snows have been across the southern Rockies.
There is enough reservoir storage space in these two watersheds to handle normal to slightly above normal snowfall without major floods; however, if snowstorms pick up, this could change. But for right now, I would rate the flood potential as average to below average.
