Saturday spring begins just in time for a strong cold front to roll in. Today is the last and best day of spring break as highs reach the low to mid 70's under sunny skies. Sunday and Monday mornings lows will be in the 30's and northern counties may get a light freeze both mornings. Here's a look at what the forecast models say the radar will look like as the cold front approaches early Saturday afternoon. I expect the front to roll off the coast by 5 pm Saturday.
