The National Weather Service in State College has issued a winter weather advisory for sleet and freezing rain headed to the area tonight.
The advisory is in effect from 4 p.m. today through 7 a.m. Tuesday.
The NWS predicts both freezing rain and sleet before 10 p.m., then freezing rain between 10 p.m. and 1a.m.
This is the first winter weather advisory the NWS has issued for Centre County this season.
The advisory extends across much of Northern and Central Pennsylvania, along major stretches of Interstates 80, 81, 99 and Route 322.
Motorists are advised to drive using caution, especially in the higher elevations around Snow Shoe and patches of I-99. Any elevated sections of roadways, including bridges, are notorious for freezing faster.
The NWS estimates there is a 100 percent chance of precipitation with light ice accumulations. The NWS also estimates new sleet accumulations of less than an inch possible.
The NWS advises that travel may be slippery, especially before midnight when sleet is expected to be the dominant precipitation type.
