Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Today: Becoming mostly sunny with a high in the upper 30s.
Tonight: Increasing clouds with light snow or snow showers late. Up to one inch of accumulation. Low around 27.
Saturday: Morning snow showers. Up to 1 inch of accumulation. High near 33.
Saturday Night: Clear and cold with a low around 15.
The extended forecast calls for sunny but cold conditions on Sunday with a low around 15 and a high near 32. Mostly sunny on Monday with a low around 15 and a high near 38. Clouds and sun on Tuesday with a low around 28 and a high near 45.
We are waking up today to fresh snowfall from last night's upper-level system that moved through the region and deposited an additional 3 to 6 inches of snow. Areas to the north and west of Baltimore and Washington have reported snowfall totals closer to two feet! The fact that the low moved closer to Norfolk VA than Cape Hatteras NC made all the difference in where the heaviest snow fell. Now that the storm system is moving away from the coast, high pressure will build in briefly and result in a mostly sunny sky today with highs in the upper 30s. A potent area of low pressure will move across the region late tonight and into Saturday morning. This low will not contain a great deal of moisture, but an inch or two of snow is possible before ending. Following this system, cold high pressure builds over the Middle Atlantic states with sunshine on Sunday. After morning lows in the mid 10s, highs will struggle to break above the freezing point on Sunday. A milder weather pattern is expected to develop next week. Monday will be cold with lows in the 10s and highs in the 30s, but daytime highs in the 40s to near 50 are anticipated for the middle and latter portion of next week. There may be a few rain or snow showers on Monday night into Tuesday morning, but otherwise fair weather is expected.
