Discussion
Winter is not over yet and there may be at least a couple of chances for snow in the Mid-Atlantic region later this week and during the upcoming weekend. One of the keys to this unfolding scenario will be a frontal boundary zone that is likely to set up to the south of the Mid-Atlantic region and this will act as a pathway for low pressure systems to ride along. At the same time, strong Arctic high pressure will set up to our north and northwest and this potential combination could lead to an impressive comeback for winter. The first wave of low pressure that could impact the Mid-Atlantic region is likely to ride along the frontal boundary zone and arrive here in the Thursday night/Friday time period; however, this system will not be all that strong and it will have only marginally cold air to work with so the result could be a changeover from rain to snow. Over the weekend, there is potential for a stronger storm and it would likely have colder air to work with as Arctic high pressure will build into SE Canada; however, it is unclear as to how far to the south this storm will track. Currently, the best chance for accumulating snow in the Saturday night/Sunday time period appears to be in the DC metro region and the least chance in NYC - Philly is somewhere in the middle. Stay tuned.
