Wider weather episode

Deepening low pressure tracking from the southeast United States on Saturday January 19, 2019 to the northeast on Sunday January 20, 2019. An arctic air mass was located across New England as the storm system approached the region. A warm front associated with the low moved north along the coast early on the morning of January 20 changing moderate to locally heavy snow to sleet and then liquid precipitation. The warmer air battled the arctic air advecting into the Lower Hudson Valley from the north. However, temperatures remained below freezing through much of the winter storm across the Lower Hudson Valley creating a significant ice accretion on top of snow accumulation. Trees and power lines were brought down due to the ice along with power outages across many towns.
