Still slight chances of ice overnight and early Friday

This is just a brief update on tonight’s chances for more wintry mix. The models haven’t changed much with regard to Fredericksburg’s involvement with ice. However, areas south of I-64 are beginning to see Winter Weather Advisories posted by both NWS Blacksburg and NWS Wakefield offices. If you plan to travel that direction late tonight or early tomorrow take heed.

Fredericksburg is still on the northern fringes of the precipitation shield from a surface low pressure that will develop and move off the southeastern U.S. coast. Here is a section of the ice probability map from the Weather Prediction Center for 7 p.m. Thursday – 7 p.m. Friday:frza probs Friday

The green shading in the vicinity of Fredericksburg indicates about a 30% chance of some ice before 9 a.m. tomorrow, after which surface temperatures will climb above freezing and any further precipitation will be plain rain. This is not a high probability but if icing does occur in and around the city it could be a high-impact event. It’s rather like the reverse of winning the lottery: the chances of it happening are slim but you keep an eye on things anyway just in case.

Meanwhile the weekend still looks nice!!
