Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:

Tonight: Variable cloudiness and cold with a few snow showers or flurries, but no accumulation is expected. The low will be in the upper 20s.

Tuesday: Variable cloudiness with scattered snow showers. The high will be in the upper 30s.

Tuesday Night: A few rain or snow showers with a low around 32.

Wednesday: Mostly cloudy with a few rain showers. Milder with a high in the upper 40s.

The extended forecast calls for a mostly sunny sky on Thursday, Friday, and Saturday with lows in the 30s and highs around 50. Clouds and sun on Sunday with a few rain showers. The low will be in the upper 30s and the high will be in the mid 50s.

A late-season winter storm dropped 6 to 12 inches of powder on Washington DC, Baltimore, and Annapolis. Just two days ago, we were basking under sunshine and 70 degrees with the promise of spring in the air, but a surge of arctic air set the stage for the development of low pressure to the south and the result was a blanket of snow across Maryland, northern Virginia, southern Pennsylvania, southern New Jersey, and Delaware. The storm brought the seasonal total at Baltimore (BWI) to nearly 40 inches. As we move through the overnight hours we can expect a mostly cloudy sky with a few snow showers or flurries as another system brushes the lower Chesapeake with mixed precipitation. Snow flurries may persist into the day on Tuesday. It will be cold again tomorrow, but nearly 10 degrees milder than today with highs approaching the 40-degree mark by afternoon. Looking ahead, a milder and more seasonable pattern is on the way with temperatures rebounding into the 40s and 50s this week. Wednesday will feature considerable cloudiness and scattered rain showers, but sunshine will return on Thursday and Friday. However, the long-range outlook features another surge of arctic air that may impact the Mid-Atlantic and New England states next week.

On the Maryland portion of Chesapeake Bay, a Small Craft Advisory is in effect through late Tuesday night. Winds today will come out of the northeast at 10 to 20 knots with gusts over 25 knots and waves up to 3 feet. Visibility may be reduced in snow shower and fog. Winds tonight will come out of the northeast at 10 to 15 knots with gusts to 20 knots and waves up to 3 feet. Winds on Tuesday will come out of the northeast at 10 to 15 knots with gusts to 20 knots and waves up to 3 feet. Winds on Wednesday will come out of the southeast at 10 knots with waves around one foot. Visibility may be reduced in rain showers and fog on Wednesday.
