Marylanders are facing “dangerously cold” temperatures the rest of this week, prolonging efforts to clean up from a winter storm that dumped snow and ice across the state.

Parts of Maryland saw 8 to 12 inches of snow and sleet on Sunday. The days ahead will bring frigid temperatures, brutal windchills and possibly another storm, according to forecasters.

The National Weather Service issued a second Cold Weather Advisory starting Tuesday at 7 p.m. for Central Maryland. The advisory is in effect until Wednesday at 11 a.m.

“The cold will be pretty persistent,” said Erik Taylor, a meteorologist for the National Weather Service’s Baltimore/Washington office. “Kind of a rinse and repeat type of forecast today.”

Sunshine during daylight hours could help melt some snow, Taylor said, and then refreezing conditions are expected overnight.

Wind chills could be as low as -8 degrees. An arctic airmass will stick around through the end of the week as temperatures stay in the teens and low 20s. Evenings will see lows in the single digits through Friday.

For those who still need to dig out sidewalks and vehicles, doctors recommend shoveling for short periods as frequently as needed to avoid straining your heart, joints and back.

But don’t put the shovel away too fast or use all of your salt. Meteorologists say another storm could hit the region this weekend.

There’s still a lot of uncertainty over the track of the storm system, Taylor said, which could approach Maryland anytime between Friday and Sunday.

If the storm is closer to the coast, it could have more impact along the Interstate 95 corridor and parts of Baltimore, Taylor said. If it’s off to the coast, the storm could hit Ocean City. For now, it’s too early to tell.

The weather service will continue to monitor as the storm develops.

Getting around Maryland

Road conditions have gradually improved as officials continue to plow snow off the streets. But it’s still icy out there, so drive slow and leave extra space between vehicles.

The rollover of a tanker truck carrying about 7,000 gallons of gasoline and diesel led to lane closures on the Baltimore Beltway near the Baltimore-Washington Parkway for much of Tuesday. As of 8 p.m., however, all lanes had been reopened, a Maryland State Highway Administration spokesperson said.

The Maryland Transit Administration announced Tuesday evening that it was resuming service on all local bus routes, including on express routes that had been suspended. The agency stressed that street conditions might require detours and that service levels were tied to employee availability.

The agency also said MARC trains will operate Wednesday on the “R” schedule across all three lines: Penn, Camden and Brunswick. MARC only offered limited service on the Penn Line on Tuesday.

Riders should check the administration’s website for travel alerts and updates.

Sunday’s snowstorm disrupted travel and shuttered schools, government offices and businesses across the state.

Watch out for ice

The continued cold snap will make roads and pathways slippery. Take slow, short steps and wear proper winter footwear when walking, advises the Baltimore City Department of Transportation.

Don’t walk on frozen bodies of water either, and look out for pets. The Anne Arundel County Fire Department rescued a chocolate Lab that was stuck on a frozen creek on Monday.

If you hit ice while driving, keep your wheel straight and ease off the gas, slowing down gently and coasting before tapping the brakes gently.

Keeping warm

Places across Baltimore will operate as warming centers amid the prolonged cold. The Mayor’s Office of Homeless Services also provides emergency overnight shelters when temperatures reach below freezing.

Many surrounding counties also provide shelters during severe winter weather, including Baltimore, Howard, Anne Arundel and Montgomery counties.

Here are some warming centers in Baltimore that are open from Monday to Friday:
