A potent California storm will come onshore tomorrow bringing heavy rain, gusty winds, and mountain snowfall to much of Central and Northern California. Passing showers and a few storms are expected in Far Southern CA & AZ Friday as well. Showers, strong winds, and mountain snow will move into the Intermountain West Saturday as yet another low moves in behind this first system late Sunday into Monday renewing the activity. An impactful Deep South freeze is likely this weekend with a frost possible as far south as the citrus growing regions of Georgia and Florida.
