Follow the First Freeze of Fall 2012 Across the Central U.S.

All observing sites in the area have fallen to freezing or colder as of October 6, and NWS Omaha/Valley will not issue any more freeze watches or warnings this season.  Freezes this year arrived earlier than usual.  One reason for this was the continued dry weather, which allowed temperatures to fall further at night than moist air would have fallen. 

The image below, updated daily, tracks the locations that have received their first freeze (32 degrees or colder) of the season.

Also, the map of the median first freeze date (32 degrees), based on the 1981-2010 period, is below. The "median" is the date when half of the years had their first freeze earlier and half of the years had their first freeze later. It is close to the "average" first freeze date, but not necessarily the same.
