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

Thursday Night: Variable cloudiness with showers late. Mild with a low around 45.
Friday: Rain showers and possible thunder. The high will be in the low to mid 60s, but falling into the 50s during the afternoon.
The extended forecast calls for a mostly sunny sky on Saturday with a high from the upper 50s near the bay shore to the mid 60s inland. Mostly sunny on Sunday with a low around 45 and a high near 55. Mostly sunny on Monday with a low in the mid 30s and a high in the upper 40s. Mostly sunny on Tuesday with a low in the lower 30s and a high in the upper 30s.
A weak cold front pushed across the bay this morning and produced widespread rain showers. Some clearing is likely during the afternoon hours with the mercury topping 50 degrees, but there may be a few rain showers through late afternoon. The air behind the front will be mild with lows on Thursday only around 35 and highs on Thursday in the low to mid 50s. On Friday, another cold front will approach from the west. A warm flow of air ahead of the front will push temperatures into the 60s. Widespread showers and possible thunderstorms will develop by Friday afternoon as cooler air from the west clashes with the mild air in place over the Middle Atlantic states. An isolated severe storm cannot be ruled out at this time. As with the current front, the air behind Friday's frontal passage will be mild so that readings on Saturday will reach 60 degrees under a mostly sunny sky. The thermometer readings will drop slightly on Sunday with highs only around 50, which is still about five degrees above seasonal average highs. As we move into next week, the "Polar Vortex" will make a return to the Middle Atlantic and New England states with unseasonably cold air and the potential for a winter storm at some point during the week. Development of low pressure often occurs on the leading edge of a cold air mass, or when the air mass is retreating to the north. Computer forecast models are indicating that low pressure may form along the arctic front and produce wintery precipitation by the middle or latter portion of next week.
