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 a “rain changing to snow” scenario and some grassy snow accumulations are possible early Friday; primarily, in the 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 Philly 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.
