Discussion
Winter is not over yet and there are three threats to monitor in the Mid-Atlantic region for the period from Thursday night through early next week. The first wave of low pressure is likely to arrive late Thursday night with little cold air in place, but it’ll actually turn colder during this event. As a result, this late week system is liable to result in mostly rain, but a mix or changeover to sleet and/or snow is not out of the question in the far northern and western suburbs. After a very cold day on Saturday, a second and stronger system looks like it will take a southern route and the DC metro region is liable to escape without any snowfall. Finally, there is an increasing chance that a third and potentially rapidly intensifying storm arrives in the Mid-Atlantic region in the late Monday/Tuesday time period of next week and there should be enough cold air in place for the possibility of snow. Stay tuned.
