A storm just offshore over the Atlantic Ocean will strengthen rapidly Thursday as it moves north. Blizzard conditions will ramp up across much of New England and Long Island, New York. As the snowstorm ends in the coastal Mid-Atlantic, blowing and drifting snow may continue to cause difficult travel conditions in the system’s wake. Farther west, snow showers and bands of lake-effect snow are expected from Michigan to Ohio, northwestern Pennsylvania and western New York. The snow will develop as arctic air moves into the region along with a weak storm from western Canada.
A cold wave will expand into the South and along the East Coast, with gusty winds. A freeze is expected as far southeast as Central Florida, which may threaten crops.
Snow will expand south over the northern Plains, but little to no accumulation is projected.
In the West, rain and mountain snow will affect areas from Northern California to western Washington. A pocket of ice will develop over interior Oregon and Washington. Much of the rest of the West can expect dry weather, although the humidity will increase in Southern California.
FOCUS: Blizzard Blasts New England
A powerful winter storm moving east of Cape Cod will produce blizzard conditions across much of New England. Crippling snow, damaging winds and coastal flooding will prevail. Heavy snow and strong winds will affect travel as far west as New York City.
