PHILADELPHIA (CBS) – A winter weather advisory is in effect for Philadelphia and the surrounding suburbs, with the exception of Chester and West Montgomery counties, where a winter storm alert is in effect. A powerful, moisture-laden storm system is expected to hit the area Wednesday morning.

Between 9 am and 11 am, the snow will arrive – covering the area from south-west to north-east. It may take a bit to start dropping heavily because of the dry air in place.
WATCH LIVE: The snow is starting to fall in the area.
From 11 am to 4 pm there will be firm snow, which can sometimes be strong. The snow will stick quickly and stack easily.
This period will present the greatest travel delays.

The final stage will involve raining in the middle of the evening or late evening. Most should see all the rain before 9pm. The rain will continue all night and will end early Thursday morning. Rainy areas may persist for the first half of the morning.
An accumulation of 2 to 4 inches of snow is likely in most of the region, and it seems that Philadelphia will be in the highest part, closer to 4 inches of snow.
We expect the highest totals in parts of Chester, Montgomery and Delaware Counties, as well as in New Castle County, Delaware, where 4 to 6 inches of snow is likely.
