I was hoping we weren't due for one this year but it's starting, damage we'll depend on duration. Here in Arroyo Grande, Ca. local weatherman has us down for the following, Thurs.- Wed. 1/10-1/16 with morning low's @ 30f,29f,27f,26f,23f,24f,25f.
Seems how things go out here you get your new trees up and going and then comes the arctic blast.
Wishing the rest of the Cal. folk's here all the warmth you can muster.
By the way high's for this coming week or so will range in the high 40's to mid 50's.
