Southern Erie, Wyoming, Allegany, Chautauqua and Cattaraugus counties will remain under a lake-effect snow warning through 10 a.m. Monday.
The lake-effect warning also extends until 7 p.m Monday for southeastern Orleans and eastern Genesee counties, where an additional 3 to 5 inches of snow was forecast for Sunday night, and up to 2 inches Monday.
While the snow is mainly to the south, chilly temperatures are present across the area.
"The temperatures are right about freezing, and there could be slick spots on untreated roads," National Weather Service meteorologist Aaron Reynolds said. "Just be careful."
