CWS Forecast: Northwest Pennsylvania

After a cold and unsettled week, the first major winter storm since November will take aim at the commonwealth of Pennsylvania Saturday into Sunday. While the entire state will feel the effects of winter storm Harper, impacts will vary across the state. Aside from a period of onset snow and minor accumulations, the Philadelphia metropolitan area will see predominantly rain. However, outside of southeast Pennsylvania snow, ice, and freezing rain will all be factors. Moderate snow accumulations along with ice can be expected in the Western and South Central region of the state, with predominantly snow along with heavy accumulations occurring in the Central and Northern tier of the state. Ice accumulation can also be expected in the Northeast region. Following the exit of winter storm Harper, extremely cold air will make its way in. Temperatures will fall below zero and in the single digits overnight Sunday and Monday night with highs struggling into the teens during the daylight hours. Temperatures will begin to moderate heading into the middle of the upcoming week. Stay warm Pennsylvania!
