There will be challenges over the next several days, the National Weather Service predicts.
It's going to be several days of what could be dangerous weather, starting this morning with a dense fog advisory, according to the National Weather Service.
Visibility at times could be limited to a half mile in the Lehigh Valley and northwest New Jersey before beginning to burn off after 10 o'clock, the weather service says.
After rain much of Friday, sleet could join in after 3 o'clock Saturday morning, possibly becoming snow an hour or so later, the weather service predicts. Accumulation should be less than an inch, the weather service says.
After an improving day on Saturday, the rain returns Sunday, turning to sleet or snow once the sun sets, the weather service says.
