Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Tonight: Variable cloudiness and windy with a low in the mid to upper 20s. North wind 10 to 20 m.p.h. at times.
Thursday: Clouds and sun. Chilly with a high in the upper 30s to lower 40s.
Thursday Night: Variable cloudiness with a low around 32.
Friday: Mostly cloudy with scattered rain showers. The high will be in the upper 40s.
The extended forecast calls for a chance of rain showers on Saturday with a low in the upper 30s and a high in the upper 40s. Clouds and sun on Sunday with a low in the mid 30s and a high in the low 50s. Mostly sunny on Monday with a low in the mid 30s and a high in the mid 50s. Mostly sunny on Tuesday with a low in the mid 30s and a high in the mid 50s.
Evening temperatures are in the mid to upper 30s, but it feels much colder with winds gusting from the north at 10 to 20 miles per hour. The windy conditions are the result of high pressure building over the Middle Atlantic region from Canada. Winds will begin to diminish by morning with thermometer readings dropping into the mid to upper 20s. Thursday will be a rather chilly day with considerable cloudiness and highs in the upper 30s to lower 40s. Meanwhile, an area of low pressure that we have been expecting to develop over the southeast states will move north along the coast and brush the area with precipitation. At the moment it looks as though temperatures will be mild enough to support mostly rain from Baltimore and Washington to the south and east. Depending on the arrival of the precipitation, there may be a brief period of sleet or wet snow but all precipitation will quickly change to rain. The heaviest rainfall looks to occur over southeast Virginia, southern Maryland, and the lower Eastern Shore of Maryland. The low will pull away from the area on Saturday, and skies will begin to clear on Sunday with highs near 50. Mild weather is expected to continue through at least the early part of next week with lows in the 30s and highs in the lower 50s, which is about where readings should be as we move toward the middle of March. Some computer models are hinting at a cold wave and a stormy pattern later next week, but there are many uncertainties at this time regarding the long-term pattern.
