This weekend will be a lesson in contrasting weather. Today, it’ll feel like March, with south winds and temperatures in the mid- to upper 70s during the afternoon. The above-normal temps will continue tonight. Then, on Sunday, a strong Arctic cold front will sweep into the area, bringing with it well-below normal temperatures, along with showers and thunderstorms. The threat for strong to severe weather also will be in the mix as the front moves through.
