If you want to get outside a bit this weekend and enjoy some legitimate sweater weather, Saturday is the day to do it — we’ll have a mix of sun and clouds with highs topping out in the mid-50s. Rain should hold off until after midnight, with periods of showers in the cards for Sunday. It’ll be a touch warmer despite the rain, but temperatures will continue to run below normal through the last shopping weekend before Christmas.
