While most of the region doesn't get major snow from this storm, there's a threat of icy roads that you should be aware of.

Storm Watch has already been issued for the Philadelphia area, as more snow is expected to fall Tuesday into Wednesday.

Some snow is likely Tuesday into Tuesday night — with computer models suggesting the best chances for several inches are just to the south of the city.

As the second storm leaves the Midwest and approaches the East Coast late Wednesday, snow may turn to more of a wintry mix in places in the Mid-Atlantic from Wednesday night into Thursday morning. A wintry mix could lead to icy conditions across the Southern Appalachians during both events.

Meteorologist Grant Gilmore is tracking snow, sleet and rain for the Philadelphia region this week. Take a look at the timing of the storm and more on which areas are expected to get the most snow.
