PHILADELPHIA (CBS) — Winter has found us and will continue to make us pay attention to it. Today is the day to get everything done — shopping, paying heating bills, calling anyone to see if they need help or will help, making plans to keep pets inside for the duration of a cold, wet, difficult time period.

First up is the clipper system that will spread about 1 to 3 inches of snow from late tonight through Monday morning. Then the clipper changes clothes, moves off the coast and becomes a Nor’easter from Monday afternoon through Tuesday morning.

While computer models still don’t have a handle on the exact evolution of this system, some generalized info at this time: 4 to 8 inches of snow expected from Delaware through southern Pennsylvania. Six to 12 inches of snow are possible from New Jersey to New England.

The snow will continue to fall on Tuesday morning. The winds will also pick up to 30 mph, which will make driving, visibility, walking and shoveling extremely difficult.

This is likely the biggest system so far this quiet winter, and it is one that needs everyone to stay alert to changing conditions.

Summary: most snow likely east and north of Philadelphia, but significant, plowable snow to the west, as well. Bitter cold follows the snow into a sunny Wednesday.

We return you now to your storm preparations.
