Light Snow Coming to an End Overnight

A mix of rain and snow will arrive for the evening, moving in from west to east. As temperatures fall this evening, the precipitation will transition to all snow. Mainly light snow accumulations can be expected, but some higher amounts in the counties nearer to Virginia are also possible. Be prepared for slick road conditions this evening into early Thursday morning. Read More >

than a half a degree warmer at London.
