Significant snowfall expected throughout the Pittsburgh area Tuesday morning with winter weather advisory issued for western Pennsylvania

A winter weather advisory has been issued for the Pittsburgh area with significant snowfall expected to hit early Tuesday morning.

The advisory includes Allegheny, Armstrong, Beaver, Butler, Clarion, Fayette, Greene, Indiana, Lawrence, Washington, and Westmoreland counties and will be in effect from midnight Tuesday through 1 p.m. on Tuesday. Eastern Ohio, northern West Virginia and western Maryland are also included in the advisory. 

"Plan on slippery road conditions," the National Weather Service said. "The hazardous conditions will impact the Tuesday morning commute." 

This snow is expected to continue through the morning commute before gradually lightening up and ultimately ending around Tuesday afternoon. A widespread 2 to 4 inches is possible for a good portion of the region, with areas to the north and in the highest ridges expected to receive 3 to 5 inches. 

Snowfall rates could reach up to 1 inch per hour, and temperatures will be below freezing on Tuesday, so what falls will stick

While the forecasted totals may not sound like a lot of snow, these accumulations will happen in a relatively short time, and that is where issues could arise during the morning commute on Tuesday. 

Road crews should have ample time on Monday to make the late commute a much better experience. If you're out on the roads, give plow drivers extra space. 

One final reminder: Give yourself extra time if you have to be out during the storm.
