A slight warm-up came Sunday and was forecast to continue into the middle of the week, with sunshine and maybe even some rain showers to speed melting -- but icy conditions are expected each night.
After spending the entirety of the storm in the 20s, temperatures inched above freezing Sunday afternoon. Baltimore/Washington International Thurgood Marshall reached at least 33 degrees, as did the Inner Harbor.
And it could get a few degrees warmer, into the mid-30s, on Monday. Meaningful relief isn't forecast until Tuesday, when temperatures could hit the mid-40s, according to the National Weather Service.
With more than 2 feet of snow across the region, including a record 29.2 inches at Baltimore/Washington International Thurgood Marshall Airport, it's going to take days to clean up and many weeks for all of the snow to disappear.
Mostly sunny skies are forecast Sunday and Monday, giving the region its best weapon to ease shoveling and melt remaining slush on roadways.
But ice will be a problem once the sun goes down. The deep snowpack is forecast to encourage even colder nights than we otherwise might experience -- temperatures dropped to 18 degrees early Sunday morning and could hit the lower teens early Monday morning.
As temperatures warm Monday, it could lead to some foggy conditions forming over the snowpack.
Relatively mild rain showers are expected to pass through the region Tuesday, and forecasters are confident it will all be liquid precipitation. But weather forecasters said they can't yet "completely rule out pockets of freezing rain" because the snowpack is keeping temperatures so cold close to the ground.
