HUNTSVILLE, Ala. (WHNT)— Yes, it is still too early to plant anything that might be damaged by frost.

A late-season cold snap is almost a guarantee in north Alabama every year. This year, it appears we will get a significant shot of cold weather during the first week of April.

The average last freeze occurs in Huntsville on April 2, so freezing temperatures during the first week of April is nothing unheard of.

A majority of the longer-range models and their ensembles signal a very cold weather pattern setting up over the United States between April 2 and 6. A large trough developing over the eastern part of the country will allow cold air to move in from Canada.

The images above show how consistent each of the major models is in the idea of the cold period of weather during the first week of April. This idea is also supported by the European model, but do to copyright issues that graphic cannot be posted here.

It’s obviously way too far out to try and be specific about just how cold temperatures will get. While we can get a clear idea of the overall pattern driving the change to colder weather, the smaller-scale features that impact temperature (cloud cover, wind, etc.) cannot accurately be forecast this far in advance.

The latest freeze on record in Huntsville is May 7, 1944! The latest freeze on record in north Alabama happened on May 30, 1984 in Valley Head.
