    NBC10 First Alert Weather: Beautiful Days Ahead After Storms

    We're finally in for a break from the humidity and storms. NBC10 First Alert Weather chief meteorologist Tammie Souza has the forecast.

    (Published Tuesday, July 17, 2018)

    What to Know

    • Severe thunderstorms moved into the region Tuesday afternoon and evening.

    • A First Alert is in effect from 1 to 9 p.m. Tuesday for the threat of downpours, flooding, hail and strong wind.

    • Thunderstorms may produce 1 to 2 inches of rain in a short period of time leading to flash flooding.

    Severe thunderstorms packing strong winds led to flooding in parts of the area Tuesday.

    We experienced hot and humid conditions through the morning and into early afternoon where temperatures pushed into the low 90s. Then a cold front triggered strong storms during the afternoon and evening.

    Flooding was reported in Pottstown and three people had to be rescued from flooded vehicles.

    Flooding also caused problems for SEPTA. Inbound train #570 was canceled from Thorndale to Center City due to high flood waters and service was suspended between Thorndale and Malvern in both directions before it reopened.

    The storms moved through the Philadelphia area late Tuesday afternoon before moving through South Jersey and southern Delaware in the evening.

    The storms caused the cancellation of community events from the suburbs (no Dining Under the Stars in Haverford) to the shore (no family movie night in Wildwood).

    Showers and thunderstorms will move offshore overnight. Skies clear Wednesday with much lower humidity and highs in the mid 80s.
