More precipitation, in the form of snow and rain, was expected to pelt the state today.
The National Weather Service predicted 3 to 6 inches of snow for Baltimore City and Anne Arundel and Howard counties, 4 to 8 inches for northern Baltimore, Harford and Cecil counties, 6 to 12 inches for Carroll and Frederick counties, 1 to 2 feet for Garrett, Washington and Allegany counties, and 3 to 6 inches for the rest of the state.
Yesterday, less than an inch of snow fell on most of the state during a minor storm that was part of a different system, said Amet Figueroa, a weather service forecaster at Baltimore-Washington International Airport.
After the snow melted, temperatures slightly below freezing made area roads slippery last night.
State police in Glen Burnie reported six weather-related accidents as of 10:30 p.m. Most were minor, but one person was taken to the Maryland Shock Trauma Center after a two-vehicle accident on Interstate 95 near the Baltimore-Washington Parkway.
Anne Arundel County police reported that a motorist was hurt in an 8:30 p.m. accident in Severna Park near the Magothy Bridge Road area.
Today's snow was expected to start about midnight, said Fred Davis, chief meteorologist for the weather service at BWI. When the snow will change to rain "depends on where you are in the state," he said.
"It will change to rain in the Baltimore area about midmorning, around 10 or 11," Mr. Davis said. "It will change around noon in the north [Baltimore, Harford and Cecil counties]. In the west [Garrett, Allegany and Washington counties] it won't change at all."
Mr. Figueroa said the change to rain wouldn't occur in Carroll and Frederick counties before midafternoon.
Mr. Davis warned of a rough rush hour this morning, saying, "How could it be anything but rough with 3 inches of snow on the ground?"
"We have crews on standby," Vanessa Pyatt, spokeswoman for the Baltimore Department of Public Works, said last night.
"We have 7,000 tons of salt on hand. The full work force of 124 crews will be in operation [this morning]."
