A fresh shot of arctic air will usher spring snow into parts of the Great Lakes and Northeast this weekend.

An Alberta clipper system diving down from Canada will deliver a round of snow and sharply colder conditions to the northeastern United States.Snow showers and heavier snow squalls are expected to track across the Great Lakes on Saturday, reaching the interior Northeast by the afternoon and New England overnight."The ground is rather warm so the snow will melt on roads Saturday afternoon across the Great Lakes, New York and Pennsylvania," AccuWeather Meteorologist Michael Doll said.In the spring, daytime snow must fall at a heavy rate in order to accumulate on roadways due to the high sun angle."Interior sections (of the Northeast) can expect slippery conditions into Sunday morning," Doll said.Motorists on portions of interstates 79, 80, 81, 86, 87, 88, 90 and 91 should remain alert for slippery spots and limited visibility late Saturday into Sunday morning. Encountering a snow squall on the roadway can reduce visibility to near zero within seconds, which can lead to numerous accidents.Once the sun goes down, wet roads could quickly become icy as temperatures plummet Saturday night.A strong cold front will sweep across the area Saturday night, with a rapid increase in the winds overnight and continuing through much of Sunday.The winds will be northwest 25 to 35 mph with gusts 50 to 60 mph and should diminish later Sunday afternoon.Trees and power lines may be downed, leading to scattered power outages.Motorists will have difficulty driving high profile vehicles especially on bridges and other elevated roadways.Check
