Dec 30, 1:41 PM Dec 30, 10:00 PM
There is a potential for hazardous commuting conditions for the

30 percent chance) Wednesday morning across the Baltimore /
Washington metro areas as well as northeast and southern Maryland,
with a light coating of snow accumulation possible on area roads.

If this threat does materialize during the Wednesday morning
rush-hour, many roads could quickly turn icy. This could lead to
dangerous traveling conditions, multiple accidents, and extensive
delays.

If commuting Wednesday morning, be aware of the POSSIBILITY of
significant travel disruptions. Plan ahead by allowing for extra
travel time, and consider using public transportation and telework
options.

Stay tuned for updates on this potential winter weather episode.
