One last snowfall is bearing down on the region. Precipitation will move into Western PA around midnight tonight in the form of moderate snow. Snow will continue through the night in areas across the Laurel Highlands up into Northwest PA. By 3-5 AM, the leading edge of snow will move into Central PA. Finally by 5-8 AM snow will move into Eastern PA, including Lancaster, Allentown, Philadelphia and all surrounding areas.

         Saturday Morning is when things will get interesting as an inverted trough sets up across Southeastern PA, extending into parts of Central PA. An inverted trough in simple terms is a relatively thin, yet heavy and persistent band of snow that is very slow moving and can deliver snowfall rates of over an inch an hour.

         It’s impossible to predict the exact region this will setup over but we do have a good idea of the general area. In the stated areas (SE-PA, C-PA), snow could last through the entire morning and into Saturday Afternoon before exiting the area. Furthermore, this event will be very elevation-based as we are in April. In addition, we do expect snowfall to stick to the pavement in areas that do receive heavier snow bands. With that said, grassy areas will begin to cover first.

        Here is our Final Call Map Forecast. Higher elevations will see the most snowfall, as much as 6″ or more on ridge-tops above 2500′. Locations throughout the Susquehanna Valley into Central PA and Pittsburgh will see 2-4″ of snow. Be sure to like us on facebook by clicking here to stay updated on this event and future storms.
