The Climate Prediction Center (CPC) released its May and seasonal forecasts on April 20, slightly modifying its previous forecast for above normal precipitation for the western half of Nebraska through early fall. This shouldn’t come as a major surprise considering the roller coaster ride we have experienced with precipitation the past few months.
While all of Nebraska has seen precipitation in the last two weeks, amounts have varied widely. More rain and possibly snow is forecast for the next two weeks and may help to improve some areas that are still abnormally dry. Find the day by day breakdown here.
