LANHAM, Md. (CBSDC) — A quick blast of winter weather created a messy commute and delayed some Washington region schools Tuesday.
An overnight mix of snow, sleet and freezing rain created hazardous road conditions that caused most school systems to delay the start of the school day by two hours.
In Maryland, public schools in Prince George’s, Montgomery, Anne Arundel, Baltimore, Carroll, and Howard counties were among the districts opting for a two-hour delay.
In Virginia, public schools in Fairfax, Loudoun, Arlington, and Prince William counties, as well as Alexandria City Public Schools, opened two hours late.
Falls Church City Public Schools opened on time despite the overnight wintry mix.
The University of Maryland, College Park opened on time.
Federal agencies in the D.C. area opened on time, according to the Office of Personnel Management.
The National Weather Service received reports from spotters ranging from less than 1 inch in parts of Virginia to more than 1 inch in Maryland.
Temperatures dipped to the 20s overnight, and some roads became snow-covered and slippery, resulting in a treacherous morning commute in some areas.
Authorities say numerous vehicles skidded off the roadway because of icy road conditions.
“It looks like frosting on the neighborhood and side streets, but it’s not so sweet to your wheels,” WNEW reporter George Mesthos said of snow-covered streets in Rockville. “It’s just enough to slide.”
A multi-vehicle crash involving a tractor-trailer completely blocked all lanes of traffic on the inner loop of the Capital Beltway in Largo for almost an hour early Tuesday.
A Winter Weather Advisory was in effect overnight Monday and early Tuesday morning, but it since has been lifted.
All the snow and ice on the ground will begin to melt as temperatures climb into the upper 40s on Tuesday. The mass melting will continue through the rest of the week as temperatures turn spring-like and approach 60 degrees.
