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.
Hello, my name is Josh Adams. This year I am a junior in high school in South Central PA. I have had a passion for weather since I was five or six years old, watching the Weather Channel when the average kid my age was watching cartoons. At age 11, I discovered that there is a significant amount of weather info online from knowledgeable meteorologists to weather models and everything in between. I had the privilege to take part in a group that held informational weather discussions nearly everyday.
I gained a significant amount of knowledge in several months back in 2012, constantly studying meteorology for hours each and just about every day. I created Northeast Weather Action in early 2013, just after the previous winter had ended. Things were pretty slow to start, however the winter of 2013-2014 greatly helped grow the page. Several of my forecasts verified nicely across the area. I met Chris during that winter in a facebook group, and we talked often about anticipated weather events. Just before the start of the 2014-2015 Winter, I added Chris to Northeast Weather Action (now Pennsylvania Weather Action), and once again we hit several key forecasts.
Chris and I are looking forward to giving you the most up to date and reliable forecasts!
