Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Tonight: Mostly cloudy with a few rain or snow showers. Low around 32.
Saturday: Morning flurries possible, then gradual clearing. Breezy & cool with a high around 40.
Saturday Night: Becoming mostly cloudy with a chance of snow showers. Low in the upper 20s.
Sunday: Becoming mostly sunny with a high around 40.
The extended outlook calls for clouds and sun on Monday with a low in the low 30s and a high in the upper 40s. Clouds and sun with a few snow flurries on Tuesday. The low will be in the mid 20s and the high will be in the lower 30s. Sunny and cold on Wednesday with a low in the lower 20s and a high in the lower 30s. Sunny and cold on Thursday with a low in the lower 20s and a high in the mid 30s. Clouds and sun on Friday with a low in the mid 20s and a high around 40.
A cold front will move from west to east across the Chesapeake overnight. Precipitation associated with the frontal passage may fall in the form of rain and snow showers along Maryland's western shore, with a dusting to one inch of accumulation possible to the north and west of Baltimore and Washington. A few flurries may linger into the early morning hours on Saturday. Behind the front we can expect increasing sunshine during the day on Saturday, but it will be windy and times with highs in the 30s. Another cold front will move from west to east across the bay on Saturday night into early Sunday. This front may once again produce scattered snow showers with a dusting possible in some areas. On Sunday high pressure will move offshore and a southerly flow will enable afternoon temperatures to recover into the upper 30s to lower 40s. Yet another cold front will approach the region from the west on Monday. Temperatures will climb into the 40s ahead of the front, but then drop into the 20s by Tuesday morning. Cold high pressure will dominate the weather pattern from Tuesday through Friday with plenty of sunshine and cold temperatures. Highs each day will struggle to reach the freezing point with overnight lows in the lower 20s, perhaps upper 10s. This cold wave will not be as extreme as the last, and a moderation in temperatures is expected by next weekend.
