Brian's exclusive forecast for Baltimore, Annapolis, and northern Delmarva:
Tonight: Mostly cloudy early, then clearing late. The low will be in the mid 20s.
Monday: Mostly sunny but cold with a high around 35.
Monday Night: Mostly clear and cold with a low around 20.
Tuesday: Mostly sunny and cold with a high near 35.
The extended forecast calls for increasing clouds on Wednesday with evening snow. The low will be in the mid 20s and the high will be in the mid 30s. A chance of snow or rain on Thursday with a low around 30 and a high in the upper 30s. Mostly sunny and breezy on Friday with a low in the mid 20s and a high in the mid 30s.
A weak upper-level disturbance moved across the area this afternoon & early evening with a period of light sleet and snow. In the Annapolis area, sleet began just before 6 p.m. and then quickly changed over to snow with about a half inch of accumulation. As this low pulls away from the area overnight, cold high pressure will build in the Middle Atlantic region on Monday and Tuesday. This will result in sunny, but cold conditions with highs about 10 degrees colder than seasonal averages. The average high this time of year is in the mid 40s, but highs on Monday and Tuesday will struggle to break above the freezing point. Overnight lows will dip into the upper 10s to mid 20s. As we move closer to the middle of the week, computer forecast models are coming into closer agreement on a coastal storm that could potentially become a nor'easter. The exact intensity and track of the storm is yet to be determined, but the ultimate track will play a significant role in our local weather. A track inland will result in a burst of snow changing to rain. A middle track right along the Atlantic coastline would result in a period of accumulating snow changing to rain, and then perhaps back to snow at the end. Another scenario takes the low just off the coast, which might bring all snow to Baltimore, Washington, and Annapolis. The potential exists for a significant accumulation of snow and ice from this system. As the storm moves away from the region on Thursday, cold high pressure will return with sunshine on Thursday and Friday. Temperatures will remain below average during the period.
