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

This afternoon: A mixture of rain, sleet, and snow with a coating of snow/ice possible north and west of Annapolis. The temperature will hold steady in the mid 30s.

Tonight: Variable cloudiness with a low in the mid to upper 20s.

Tuesday: Mostly cloudy and cold with a high in the mid 30s.

Tuesday Night: A good chance of freezing rain, then changing to rain late. Low around 30.

Wednesday: Rain showers giving way to a mostly cloudy sky later in the day with a high around 40.

The extended outlook calls for mostly sunny and cold conditions on Thursday and Friday with lows around 25 and highs near 35. Increasing clouds with a chance of snow on Saturday night and a low in the upper 20s. A chance of snow or mixed precipitation on Sunday with a high in the mid 30s. A chance of snow early on Monday, then mostly sunny and cold with a high in the lower 30s.

Low pressure moving along a frontal boundary has produced a wide range of precipitation across the bay region today, with heavy snow across northern Maryland and heavy rain in the Baltimore-Washington-Annapolis triangle. Just a few degrees has separated frozen from liquid precipitation. In the Annapolis area, moderate to heavy rain has fallen all morning with a changeover to sleet having occurred around noon. Rainfall amounts of more than 1" have been recorded. As we move through the afternoon hours, leftover precipitation will taper to light sleet, snow, or rain showers before ending. With temperatures a few degrees above freezing, any sleet or snow accumulation will only occur on unpaved surfaces. To the north, heavy snow has accumulated from 3 to 6 inches with isolated higher amounts across the northern tier of the state. The area of low pressure will pull away from the region tonight. Consequently, the sky will clear and the mercury will dip into the mid to upper 20s by morning. On Tuesday, a new area of low pressure will approach the bay region. A mostly cloudy sky during the day will give way to freezing rain later in the evening. Temperatures will gradually rise above freezing by early Wednesday morning and all precipitation will change to rain showers; however, icy conditions may be present around the area during the morning rush depending on the time of the changeover from freezing rain to rain. Looking ahead, a cold Thursday and Friday will be followed by a potential major winter storm for the Middle Atlantic and New England states by next weekend. More details will be posted on Examiner updates and on my Facebook and Twitter pages.
