Pittsburgh is preparing for a weekend of variable weather as cold fronts traverse the Great Lakes region. KDKA-TV meteorologist Trey Fulbright forecasts cooler temperatures and potential precipitation, urging residents to stay informed and prepared for sudden changes. These cold fronts, acting as boundaries between warmer and cooler air masses, are expected to bring unsettled conditions, including showers, thunderstorms, and temperature drops. Given Pittsburgh's proximity to the Great Lakes, the city is particularly vulnerable to these weather impacts.
