After a sloppy start to the week, the sun will return to the Baltimore area briefly, as will higher temperatures peaking midweek.
But it is not expected to last long, with the cold returning Thursday and Friday.
"It's going to be quite a shift from last week," said Greg Schoor, a meteorologist with the National Weather Service in Sterling, Va. "It's what we say in the meteorology business is a 'dramatic pattern shift' — one extreme to another."
Rain showers were expected Monday afternoon with a slight chance of rain at night, less than a tenth of an inch possible and an overnight low around 38, according to the National Weather Service.
Temperatures are expected to warm up Tuesday with a high of 51 and some partial sun. Showers are likely to return overnight with a low around 44.
Wednesday's temperature is predicted to be the highest of the week — at 59. The forecast calls for an 80 percent chance of precipitation with thunderstorms possible after 1 p.m. Half to three-quarters of an inch of rain is possible. Showers are likely again before midnight and some fog is possible.
Thursday will be partly sunny, but cooler temperatures are expected to return with a high near 43 and a low around 25. Friday's high will reach just 34 degrees with an overnight low of about 20. Snow flurries are possible.
Monday's commute was slickened by ice, though accumulations were mostly less than a 10th of an inch, according to the National Weather Service. Just .017 inches of precipitation was recorded at Baltimore-Washington Thurgood Marshall International Airport between 6 a.m. and noon Monday.
Many local school districts, including Baltimore City and Howard County, were under a two-hour delayed opening on Monday, while Harford County schools were closed. Baltimore and Anne Arundel county schools were closed because of a professional development day and the offices opened two hours late.
