    The snow won't be in the area until late Wednesday morning but roads are already getting slippery.

    Patchy black ice and freezing fog are developing on roads in the North and West suburbs, creating slippery conditions. The ice is being caused by below freezing temperatures and left over moisture from rain showers. The freezing could lead to a slippery Wednesday morning commute before the snow even arrives.

    A quick developing Alberta clipper is expected to bring snow to most of the area Wednesday and could drop up to 4 inches in some neighborhoods.

    The storm could affect the afternoon and evening commutes, said NBC10 First Alert Weather Meteorologist Brittney Shipp.

    The snow system will move in from the west starting around 10 a.m. in parts of Chester and Berks Counties before moving across the area. The snow will continue on and off from 3 to 6 p.m.

    The snow should be at its heaviest and most widespread right in time for the evening commute from 6 to 8 p.m.

    The National Weather Service issued a Hazardous Weather Outlook ahead of the storm. Temps in much of the area should be cold enough for snow but some areas — especially south and along the coast could see a wintry mix of rain, sleet and/or snow.

    “There should be snow for most of the area,” said Shipp.

    Shipp warned that at times throughout the afternoon and evening the snow could taper off but then return in parts of the area. It should finally move out around midnight but not before leaving accumulation in many areas.

    Snow Totals:

    - Parts north and west of the I-95 Corridor: 2 to 4 inches
    - I-95 Corridor, immediate Philadelphia suburbs: 1 to 3 inches
    - Southern Delaware & southernmost New Jersey: coating to 2 inches

    Some areas could see more or less snow than even neighboring towns depending on elevation, temperatures and other factors.

    Snow Timeline:

    North and West Suburbs - Snow moves in after 10 a.m., picks up between noon and 3 p.m., lasts through evening commute

    I-95 Corridor - Snow moves in between 1 p.m. and 3 p.m., wintry mix also possible, lasts through evening commute

    Shore Timeline - Rain, then wintry mix, then snow moves in between 2 p.m. and 4 p.m., lasts through evening commute

    Most of the system will be gone around 11 p.m. Wednesday. However, the next concern once the system is gone will be re-freezing on roads, causing more icy conditions which. Expect to take some extra time getting where you're going Thursday morning since slippery roads are expected.
