Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Today: Cloudy early with a few snow showers, then clearing. High 40.
Tonight: Variable cloudiness with a low in the upper 20s.
Friday: Clouds and sun with a high in the 40s.
Saturday: Clouds and sun with a high in the 40s.
Sunday: Mostly cloudy with a good chance of rain showers. High around 50.
The extended outlook calls for a mostly sunny sky on Monday with lows around 35 and highs around 45. Mostly sunny on Tuesday with a low around 27 and a high around 35. Mostly sunny on Wednesday with a low around 25 and a high near 35.
An upper-level disturbance is producing snow showers across the northeast states this morning. One snow band has dropped into northern Maryland and a few snow flurries associated with this band may fall as far south as Annapolis. Temperatures last night did not get as cold due to the extensive cloud cover. Temperatures at 0930 are in the lower 30s in the Annapolis area. As the day progresses we can expect gradual clearing with a mostly sunny sky this afternoon. The mercury will rise into the lower 40s. On Friday and Saturday, an area of high pressure will move to our south and create a more southerly flow across the region. Consequently, temperatures will moderate into the 40s each day. Later in the weekend an area of low pressure in the southern states will move northeast toward the Mid-Atlantic region and produce widespread rain showers. As is typical this time of year, the exact track of the low will determine the precipitation's type and intensity; however, surface temperatures ahead of the system will be too warm to support frozen precipitation. Therefore, we can expect rain on Sunday that may change to a brief period of wet snow Sunday night into Monday morning as the low pulls away from the coast and colder air spills into the area. High pressure will become more dominant next week and will produce sunshine with seasonably cold temperatures through the end of the year.
