Climatology of a
First Fall Freeze/Killing Freeze
across Western and North Central Nebraska


The farming/gardening growing season typically ends during the months of September or October across western and north central Nebraska.  Many plants are sensative to freezing conditions, and will stop their production once temperatures reach or fall below 32 degrees. A freeze will occur when temperatures reach or fall below 32 degrees. While some plants are able to with stand a brief period at or just below 32 degrees, most plants will not survive once temperatures drop to or below 28 degrees (often refer to as a killing freeze). Below are several sites across western and north central Nebraska with the probability of a freeze or killing freeze based on reports from airport and cooperative observations.  The probability is based on the chance a freeze/killing freeze will occur on or before 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/killing freeze conditions are forecasted.  The links are different for freeze conditions (equal or less than 32º) and killing freeze conditions (equal or less than 28º).

Below is a list of numerous sites across western and north central Nebraska.  The probability is base on the chance a freeze/killing freeze will occur on or before 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/killing freeze conditions are forecasted. The links are different for killing freeze conditions (equal or less than 28º) and freeze conditions (equal or less than 32º).
