Treacherous travel is likely across parts of southern Ontario through the weekend, as powerful snow squalls affect heavily travelled highways. Snow squall watches and warnings are in effect, as well as winter weather travel advisories for the deteriorating and dangerous conditions.

Severe winter weather is not the most common occurrence for many areas in the Roanoke Valley and Southwest and Central Virginia. However, during the early evening of January 3, the National Weather Service in Blacksburg (NWS) issued a Snow Squall Warning for areas from Pulaski to Roanoke.
