Nebraska average rainfall

Answer 1

Nebraska has an average annual precipitation of around 560 millimetres (22.2 inches), although there is a steady gradient from around 760 millimetres (30 inches) in the southeast to around 375 millimetres (15 inches) in the western Sand Hills.

Most of this precipitation is rain, though in Omaha there is typically around 68 centimetres (26 inches) of snowfall, which equates to 50 millimetres (2 inches) of rain and leaves around 710 millimetres or 28 inches of actual rainfall. In western Nebraska there is a similar amount of snow but substantially less rain - as little as 315 millimetres (12.5 inches) of actual rainfall in the northwest.
