Overnight Update: Ice, Snow, & Wind

Freezing rain (rain falling into surface temps of 32 degrees or colder) has been occurring in the Richmond Metro Area since 8 PM. Trees and power lines have a glaze of ice on them, and additional icing will occur as another band of rain moves through between 10:30 PM and 11:30 PM. Temperatures in the mid-levels of the atmosphere will cool to a point that snow will be the precipitation type after 2 AM. The back edge of the current area of precipitation will have moved through the metro by then, but wrap-around moisture from a rapidly intensifying surface low will bring light snow back into the area a few hours either side of sunrise. Very strong winds are still expected with this storm system, with wind speeds sustained in the range of 25-35 mph, and gusts to 45 mph. Winds in western Virginia could gust higher than 55 mph.
