Brian's extended forecast and forecaster's notes

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

This afternoon: Mostly sunny with a high around 40.

Tonight: Clear and cold with a low in the upper 20s.

Saturday: Increasing clouds with light snow or flurries. Up to 1" may accumulate. High around 35.

Saturday Night: Mostly cloudy with a low in the upper 20s.

The extended forecast calls for a mostly cloudy sky on Sunday with a few rain or snow showers and a high in the mid to upper 30s. Mostly sunny and cold on Monday and Tuesday with lows in the 20s and highs in the 30s to near 40.

High pressure is providing sunny but chilly weather on the Chesapeake today with current early-afternoon temperatures in the mid to upper 30s. The mercury will touch the 40-degree mark this afternoon. As we move into the evening and overnight hours, temperatures will fall back into the 20s under a clear sky and light winds. Clouds will increase toward morning. On Saturday, a weak area of low pressure will move northeast and exit off the North Carolina coastline. This low is the same system that computer forecast models had predicted might form into a powerful eastern snowstorm; however, this low will have limited energy and moisture. Consequently, any precipitation that falls will be very light. The field of precipitation looks to brush southern Maryland and the lower Eastern Shore, as well as Hampton Roads in Virginia. As a result, it appears that snowfall on Saturday in the Annapolis area will be limited to snow showers or flurries. A slight northward track of the low may bring a round of light snow to the region, but that appears unlikely at the moment. On Sunday, another area of low pressure will skirt across the Appalachian Mountains and move just to our north. This system will contain limited amount of moisture. As with the Saturday system, snow showers or flurries appears to be the likely result with a slight chance of a bit more accumulation. Temperatures will be cold enough over the weekend to support all snow in the region. Moving into early next week, cold high pressure will ensure a continuation of below-normal temperatures, but nothing extreme. A storm system may impact the area by the middle of next week. As of today, the European model is favoring the potential for accumulating snow in the Middle Atlantic region, but other models are less aggressive.

On the Maryland portion of Chesapeake Bay, no advisories are currently in effect. Winds today will come out of the northwest at 10 knots with waves less than one foot in ice-free waters. Winds tonight will come out of the north at 10 knots with waves less than one foot in ice-free waters. Winds on Saturday will come out of the northeast at 10 knots with waves less than one foot in ice-free waters. Visibility may be reduced in snow and fog. Boaters should prepare for icy conditions on the bay. Marine information is provided as general guidance. Boaters should always stay tuned to the latest forecasts and advisories from the National Weather Service.
