First the Cold, then the Heat

Cool and dry air will settle in over the area tonight, allowing temperatures to fall into the mid 30s in parts of NW VA. A frost advisory is in effect for Albemarle, Nelson, Greene, Orange, Madison, and Culpeper counties overnight, with the expectation of lows in the range of 33-36 degrees. The weekend pattern still features a large ridge of high pressure building over the SE US, resulting in highs in the upper 80s and a few low 90s.
