Forecasters are tracking a winter storm that could bring snow to the Philadelphia area Wednesday.

The latest forecasts have the storm’s main impact arriving after the morning rush hour, with snow falling throughout the day before turning into a wintry mix of snow, sleet, and freezing rain late Wednesday and Wednesday night, the National Weather Service said.

A winter storm watch, indicating the potential for snow, sleet, or ice accumulations that affect travel, is in place starting at 6 a.m. Wednesday and lasting throughout the day. Slippery road conditions are expected, the weather service said.

The current timing for the arrival of snow is likely to lead to early school closures, if districts open in the first place, based on past procedures.

Accumulation projections range from one inch at the Shore to four inches in Philadelphia’s western suburbs.

The wintry mix Wednesday night will transition into rain, which is expected to fall into Thursday morning before giving way to partly sunny skies and warmer temperatures, with a high above 50 degrees.

In the meantime, the sun is expected to shine brightly Tuesday, though the mercury is only expected to reach the high 30s.

Overnight lows Monday night and Tuesday night are forecast to be in the mid 20s.
