Thursday, Friday, and Saturday will likely produce the first freeze events of the season across most of the lower elevations of North Carolina (higher elevations have already experienced a freeze).
How does the timing of the first freeze in 2013 compare with historical climatology?
Below is a table with dates of average, earliest, and latest freeze for a few lower-elevation sites across the state. (Note that we're defining a freeze as minimum temperature <= 32°F). This table was produced using our online Climate Thresholds Tool.
|City||Average Date of First Freeze||Earliest Date||Latest Date|
|Greensboro||November 1||October 4, 1974||December 1, 1964|
|Charlotte||November 7||October 9, 2000||December 10, 1989|
|Fayetteville||November 7||September 20, 1971||December 3, 1956|
|Elizabeth City||November 12||October 21, 1940||December 11, 1919|
|Raleigh||November 13||October 3, 1974||December 27, 1992|
So the timing of this year's freeze is a bit early, but not unusually so. Most of North Carolina experiences their first freeze in the first couple weeks of November. This year, it comes about a week early.
