Climatology of a
Late Spring Frost/Freeze
across Western and North Central Nebraska

Warm temperatures in March and April can kick start the farming/gardening season across western and north central Nebraska.  However, typically we still have the potential for freezing temperatures into the month of May. Many plants are sensitive to frosting and/or freezing conditions.  Frost can develop when the temperature reaches or drops below 36 degrees, while a freeze will occur when temperatures reach or fall below 32 degrees.  Below are several sites across western and north central Nebraska with the probability of a frost or freeze based on reports from airport and cooperative observations.  The probability is based on the chance a freeze/frost will occur after the date.  The interactive forecast is a graphical representation (a bar across time) of National Weather Service forecasted hourly temperatures over the next 7 days.  If there is no bar then no freeze/frost conditions are forecasted.  The links are different for frost conditions (equal or less than 36º) and freeze conditions (equal or less than 32º).
