Wintry precipitation and cold temperatures came together over the weekend to make this icy landscape Monday morning atop Mercersburg mountain. Even colder weather is expected to grip the region late in the week, after an area of low pressure moves across southern Pennsylvania Wednesday night. According to the National Weather Service the coldest air so far this winter will follow Thursday and Friday and combine with a gusty northwest wind to bring bitterly cold wind chill temperatures. 003p1_xlg.jpg
