Temperatures fall fast overnight with a frost and freeze possible by sunrise. A small 5-10 mph north breeze may keep the frost away for some, but many are expected to drop below freezing. A hard freeze is possible for inland areas as temperatures reach the 20s. More frost and a lighter freeze are possible Thursday morning with the frost threat much patchier Friday morning. The weekend is looking great with 70s on Saturday and a chance at 80s on Sunday.
