Discussion
Spring officially begins today and the weather will be anything but spring-like in the Mid-Atlantic region. Strong, cold high pressure from southeastern Canada will build into the Northeast US over the next 24 hours and this will be a key player and an important cold air source for the Mid-Atlantic region during the upcoming long-lasting and significant weather event. This upcoming event will, in fact, be kind of a "two-parter" with the first system likely to bring a mixed bag of snow, sleet and/or freezing rain today into tonight and there can be an ice build-up on some surfaces. The second and stronger system comes late tonight and Wednesday and this is likely to develop into an all-out snowstorm for the DC-to-Philly-to-NYC-to-Boston corridor with significant snowfall here on the order of a 8-14 inches by tomorrow night. Snow accumulations later today and tonight will be limited due to the expected mixed variety of the precipitation. In addition, there will be increasing NE winds adding to the threat of power outages and perhaps even possible isolated "thunder snow" during this event with very heavy snow rates possible later tomorrow.
