Winter Storm Iola could dump up to 8 inches of snow on the region Friday and Saturday, though the storm will start late enough that there should be no trouble with the evening commute, the National Weather Service said.

The snow will begin after 9 p.m. Friday, with the bulk of the snow falling after 11 p.m., the NWS said. The snow will change to rain early Saturday morning and about a tenth of an inch of ice is likely.

When and where the snow changes to rain will be the deciding factor in how much snow we get.

“A distance of 30 miles could make the difference between 6 inches of snow and an inch of rain,” AccuWeather.com Chief Meteorologist Elliot Abrams said.

In the worst-case scenario, the National Weather Service said, parts of the region could see up to 8 inches of snow. Throughout the Philadelphia region, forecasts are calling for 2 to 4 inches of snow on Friday, Jan. 23, and an additional 1 to 2 inches of snow on Saturday.

The storm will be during off-hours, but drivers should “be prepared for slippery roads and limited visibilities,” the NWS said.

A Hazardous Weather Outlook and Winter Weather Advisory are in place for the region.
