As temperatures rise above freezing during the day, precipitation will transition to a mix of rain and snow. Later, as temperatures drop below freezing again Saturday night, the precipitation will change back to all snow.

Saturday Night and Sunday Hazards
"A flash freeze is expected as temperatures fall to around 20°. Any liquid on the roads will freeze, creating a layer of black ice for Sunday morning travel."
Temperatures will likely remain below freezing all day Sunday, potentially keeping untreated roads hazardous.
