    Heavy rain and thunderstorms are expected Monday afternoon and evening as a robust cold front passes through the East Coast.

    Rain will be heavy at times, and some storms may be severe, forecasters say.

    [UPDATE: TORNADO WATCH ISSUED FOR THE NEW JERSEY AREA]

    “There is the potential for moderate to heavy rainfall from this afternoon into this evening which could result in flooding in areas of poor drainage,” a National Weather Service-Mount Holly Hazardous Weather Outlook advises for the New Jersey region. “Also, scattered thunderstorms during the afternoon and early evening hours may be accompanied by strong wind gusts.”

    Wind gusts “should top out between 30 and 40 mph,” and most could see an inch of rain, with isolated amounts of two to four inches not “out of the question,” according to forecasters at the National Weather Service-Mount Holly in its latest forecast discussion. 

    The National Weather Service Storm Prediction Center has placed the area in the “slight risk” category for severe thunderstorms. 

    Future radar imagery indicates arrival in eastern Pennsylvania/western New Jersey around 4:00 p.m, passing off the coast by around 9:00 p.m.

    Once the cold front departs out to sea tonight, the wind will shift to the northwest, delivering much drier air. 

    Sunshine will return for Tuesday and Wednesday, when high temperatures will reach the low 70s. Slightly above normal temperatures in the low 70s will continue for the remainder of the week. There will be a chance of showers straight through the weekend.
