Maryland highway officials warn of snow Monday

ROCKVILLE, Md. (AP/WJLA) - As D.C. area residents were enjoying an unseasonably warm Sunday, transportation officials are warning of snow expected at the start of the work week and are urging motorists to plan ahead.

The National Weather Service placed part of the Mid-Atlantic region under a winter storm watch through Monday afternoon. The weather service says there's potential for 5 inches of snow or more. Up to 6 inches of snow is possible in northern Delaware.

Rain is expected to mix with snow after midnight, changing over to all snow early Monday.

The weather advisory covers central and western Maryland, northwestern Virginia and northern Delaware. Conditions expected in the Baltimore-Washington metro areas are still uncertain.

Maryland state highway officials say drivers should prepare to avoid or delay travel if conditions worsen Monday morning. Road crews are expected to be called in around midnight.
