That is cold Cheryl...hope it does not slide further. I remember we had a fluke of a hard freeze in 2012 but it was in January where our forecast says Hi of 49 and low of 31...but it slid further to 21F. That is way too cold for us already..I guess blessing is it did not go to any negative digits. Lost some of my plants then too.
Anyhow.....keep warm and safe!
