A major winter storm is anticipated to impact the mid-Atlantic region this upcoming weekend, as a robust Arctic high-pressure system moves in. Residents are advised to prepare for treacherous travel conditions and significantly colder temperatures.
In Norfolk, Virginia, the 13News Now Weather Team has issued a Weather Impact Alert, noting that forecasts consistently indicate a significant winter weather event is on the way. Starting as early as Saturday morning, the development of this storm is expected to be influenced by abundant cold air that is already in place, increasing the likelihood of severe winter precipitation.
Several key meteorological factors are at play in this forecast. An exceptionally strong Arctic high will settle over the central U.S. and Great Lakes by Friday, driving cold air into the mid-Atlantic region. Additionally, an active storm track is predicted to draw moisture from the southern Plains into the Tennessee Valley and Deep South, which will interact with the colder air mass.
Current models show a high probability for winter precipitation, with an 80% chance of areas receiving more than 3 inches of snow and a 60% chance of exceeding 6 inches in certain locations. While a widespread winter event is likely, the types of precipitation—whether snow, freezing rain, or sleet—and the specific amounts will hinge on two critical factors: the storm’s track and the strength of the cold air.
A more northern track could lead to an increase in freezing rain and sleet, whereas a track further south may result in higher snowfall totals for the southern parts of the region. The depth of the cold air will also play a significant role in determining how precipitation types transition between rain, ice, and snow.
As the winter storm approaches, residents should stay informed and take necessary precautions to ensure their safety during the potentially hazardous weather conditions.
