I'd probably reconsider any cross-country journey Thursday into Friday, at this stage, unless of course urgent. Problems with this wintry spell are several fold. As snow depths are likely to increase rapidly due severity of cold, road conditions will deteriorate pretty quickly too. Add drifting, blowing snow. With day temperatures closer to freezing this wintry spell is going to be a notable one. Not the usual sleety wet snow, slush fest.
Good chance some will be building igloos by next week end, maybe before
