It might be a messy commute for drivers tomorrow morning.

According to the National Weather Service, a wintry mix of snow, freezing rain and sleet is expected to begin today and move through the region during tomorrow morning's commute.

A winter weather advisory has been issued for areas of eastern Pennsylvania and central New Jersey, including parts of Chester, Montgomery and Bucks counties. As much as 2 to 5 inches of snow are expected to fall north of I-78 starting as early as midday today, with the heaviest precipitation expected after midnight.

Not much snow accumulation is expected in Philadelphia, though a flurry or two were spotted Sunday afternoon as south as northern Delaware. A Code Blue, the first of the season, remains in effect in Philadelphia through Monday morning at 6:00 a.m.

Forecasters say Philadelphia could get hit overnight with some light snow, along with freezing rain and sleet, but by Monday morning all the precipitation should be rain. Drivers along the I-80 and I-78 corridors will experience the most hazardous travel conditions.

The good news is temperatures are forecast to rise quickly Monday morning, and could even extend into the low 50s. But don't get too comfortable - a new round of cold air is forecast to move in Thursday through Friday.
