If you thought getting around today was tricky, consider what the weather experts predict for tomorrow: temperatures dropping into the 20s overnight and hovering near the freezing mark tomorrow with additional snow tomorrow and later in the week.
The conditions were expected to create hazardous driving tonight in the metropolitan area.
Today the snowfall closed 10 Maryland school systems all day and caused scores of accidents throughout the Baltimore metropolitan area. Police agencies reported no major injuries.
Some public school systems opened late, and those in the city and Anne Arundel County closed early this afternoon.
"The snow will probably fall throughout the day while the temperature drops," said Bill Miller, a forecaster for the National Weather Service at Baltimore-Washington International Airport.
Another low pressure system approaching from the southwest probably will bring more rain and snow tomorrow, Wednesday and Friday, according to the weather service.
Miller said he expected that up to 4 inches of snow would accumulate in Baltimore and up to 7 inches in the northern and western counties before the snow ends today. He said he expected the temperature to dip into the 20s tonight and climb to just below the freezing mark tomorrow.
Officials at BWI airport closed the runways and taxiways for an hour at midmorning to clear the snow.
While harried police officers tended to countless accidents during the morning rush hour, emergency crews were busy on city and county roads salting and plowing slushy snow.
Baltimore reported more than 100 trucks out on the streets by daybreak, while Baltimore County dispatched more than 70 salt trucks to help clear primary routes and secondary roads.
By late morning, State Police were warning motorists to drive carefully along sections of Interstate 83, where icy spots over bridges and overpasses were proving troublesome.
"Our problems seem to be centered on I-83 and Owings Mills Boulevard and Reisterstown Road," said Cpl. Bill Bokel. State Police in Bel Air closed down Md. 23 near Madonna after a trash truck hit a telephone pole there.
Howard County also reported dozens of morning rush hour accidents, while city police handled about the same number.
School officials in Harford, Howard, Baltimore, Carroll, Frederick, Cecil, Kent, Washington, Queen Anne's and Montgomery counties gave students the day off because of the weather, and other counties opened classes late. The city, which closed schools early at 1 p.m., had opened them on time.
State Police said Phase 2 of the snow emergency plan was in effect in Baltimore and Baltimore County. That means motorists must have snow tires, chains or all-weather radials on their vehicles, and parking will not be allowed on designated snow emergency routes.
