The National Weather Service says high winds in Pennsylvania that may have been tornadoes flattened a house and several barns and blew out windows. Severe storms moving across the state overnight have knocked out power to tens of thousands of customers. Nearly 38,000 customers of the state’s major utilities are without power Monday morning. PPL was hardest hit, reporting outages throughout its coverage area in central and eastern Pennsylvania. High winds and falling temperatures are forecast for Monday.
