Winter is not over.
Though Sunday's high temperatures could hit a spring-like 60 degrees, there's a chance of snow Sunday night, according to the National Weather Service.
"We're looking at the possibility of a little bit of snow," said Carl Barnes, a meteorologist with the weather service's Baltimore-Washington forecast office.
Any snow is likely to be less than an inch. There's a 22 percent chance of an inch or more, Barnes said.
Even though temperatures will drop to around freezing before the snow comes, pavement will retain some of the weekend's heat, so any snow might not stick to roads very much, Barnes said.
The front that brings the snow will usher in a week of colder-than-normal temperatures, an odd juxtaposition to the weekend's balmy weather. Saturday's high temperature at BWI Thurgood Marshall Airport in Linthicum was 61 degrees.
"This weekend, we've been 10 to 15 degrees above normal, whereas for this coming week, we'll be 10 degrees or so below normal," Barnes said.
Monday's high will be in the low 40s, but the rest of the week will see highs in the 30s.
Meteorologists also are tracking a coastal storm that could hit Maryland Tuesday night or early Wednesday morning.
Barnes said it's too soon to tell how Maryland would be affected. Barnes said the computer models are not yet in agreement whether Maryland will get hit or not.
