A strong cold front will sweep through the region overnight, bringing rain and a dramatic drop in temperatures on Sunday. While Saturday will see mild conditions in the 70s, the mercury will plummet into the 40s by midday on Sunday, with wind gusts and potential snow showers in the mountains. The chilly air will continue to flow in, leading to widespread frost and freeze alerts for Tuesday morning before a return to spring-like warmth by the end of the week.

Why it matters
