3/10 Early AM All Zones Update: Light to Moderate Snowfall Today
A wave of low pressure moving east from the Delmarva region, will bring a light to moderate snowfall to much of the region. Over the higher elevations over Northwest NJ and parts of Lower Hudson Valley snow has been falling over past few hours and surface temperatures have dropped to near freezing. So some accumulation is likely occurring on colder surfaces.
Closer to the coast, boundary layer temperatures may initially support some rain or wintry mix at the start, But it should quickly change over to snow, as lower dewpoints and wet-bulb temperatures, will support more cooling down to surface. Surface temperatures should fall down into low to mid 30s everywhere over by 9am.
