    NBC10 First Alert Weather: Temperature Dip Coming

    Friday brought high temperatures and sunshine to our region that had plenty of people heading outside, but the end of the weekend will be a different picture. NBC10 meteorologist Glenn "Hurricane" Schwartz has your neighborhood forecast.

    It's time to soak up the sun, but don’t put your coats in the attic just yet. Although Saturday will be warm and sunny, a cold front will arrive Sunday with a 30-degree temperature drop.

    SATURDAY MORNING FORECAST

    That's when the Philadelphia area will experience a "back-door front," which is cold air that comes from the northeastern United States. (Think Boston.) This front will bring the plummet, along with clouds and patchy rain or drizzle throughout the day. Temperatures will stay in the 40s most of the day through much of the area.

    SUNDAY MORNING FORECAST

    On Sunday evening, the front will continue south, while another begins to come in from Chicago. These two fronts will converge Sunday night, leaving Monday morning stormy. That is why we’ve issued a First Alert, starting at 4 a.m. Monday through 12 p.m. Heavy rain and possible gusty thunderstorms will complicate the morning rush hour.

    SUNDAY AFTERNOON FORECAST

    The coldest day of the week will be Tuesday, when gusty winds will make temperatures in the 40s seem even colder. After that, temperatures will return closer to seasonal averages, with highs mainly in the 60s.
