Our first widespread snowstorm of the season is expected to take shape across western Pennsylvania Tuesday into early Wednesday morning. Winter Storm Warnings and Winter Weather Advisories have been issued, and travel may be very difficult during the storm. Below is future radar timing, followed by our final snowfall map.
SNOWSTORM TIMING
Light to moderate snow will move in from the west early Tuesday morning. At first, it may have a hard time sticking as temperatures will be near freezing. Temperatures will quickly drop a few degrees below freezing. Below is future radar for 2:00 AM Tuesday.
The light to moderate snow will push east through mid-morning Tuesday. Some snow showers may make their way into central PA, but aren’t expected to accumulate. Here is future radar for 7:00 AM Tuesday.
Snow will continue in western PA as we head into Tuesday afternoon. Lake-effect snow will enhance snowfall rates in the snowbelts of northwest PA. Below is future radar for 12:00 PM Tuesday.
As you can see, this will be a long duration snow event, and won’t feature heavy, blinding snow. Instead, it will be a light to moderate snowfall that gradually accumulates. The snow will persist into Tuesday evening. Here is future radar for 6:00 PM Tuesday.
At last, the snow will wind down early Wednesday morning in western PA. A few lake-effect bands may continue, but for most the snow should lighten and then end. Below is future radar for 12:00 Wednesday.
