Meteorologist Henry Margusity forecasts active winter weather leading into the holiday, starting with a system tracking into the Northeast tomorrow, December 23rd. This disturbance is expected to bring a general 1 to 4 inches of snow to the region, with locally higher amounts possible and a risk of ice accumulation across the Appalachians and south-central Pennsylvania. The system will likely bring snow into New York City and potentially as far south as Baltimore before transitioning to a wintry mix. Concurrently, a "Pineapple Connection" is streaming moisture into the West, dumping heavy snow across the Northern Rockies and the Sierra Nevada mountains.
Looking beyond Christmas a significant threat for a "substantial" winter storm developing between December 26th and 30th. He notes that fresh cold air will drain down the Hudson Valley and lock into the Mid-Atlantic states, creating a setup ripe for heavy snow and ice depending on the exact track of the storm. With cold temperatures persisting and multiple systems lining up through the end of the year, he advises viewers to remain prepared for hazardous walking and driving conditions throughout the holiday week.
