The snow arrives between 8 a.m. and 10 a.m. Thursday from southwest to northeast. It will only last a few hours in most areas (longer the farther north you live). The majority of the snow accumulation will be over by early afternoon.

Storm Freya whipped from the Midwest into the Northeast Thursday, coating roads in slick ice from Baltimore up the I-95 corridor, making for dangerous commutes and forcing school closures and delayed openings.

The Boston 25 Weather team is closely tracking a system that could bring up to 5 inches of snow and icy driving conditions on Thursday before an eventual flip to rain in some places.
