Potential of Tuesday Plowable Snow Growing, Too Early For Amounts

Estimated reading time:2 minutes, 14 seconds

        While the potential of a plowable snow Monday Night into Tuesday is growing, there is still much to be worked out especially regarding what areas will see the most snow. It all starts with a low pressure off the Carolina Coastline Sunday.

        A low pressure will move northeast, likely staying far enough away from the coast, we will not have to worry about major snow. That’s the first piece of the puzzle. The second piece is how far that storm is off the coast and how strong it gets, this would affect how much energy is leftover for our main system.

        Our snow will come from an Alberta Clipper, transferring its energy to a secondary low pressure south of us. Here is where the most uncertainty still lies. How far south of us will the low pressure form and in what direction will it move? Either way, if we had to select an area that most likely will get moderate snow accumulations no-matter what occurs, it would be across Southcentral PA between Somerset County to Huntingdon County to Adams County down into the Winchester, VA area.

        If the secondary low pressure forms in Virginia and moves right off the coast directly east-northeast, then it’s likely East Central and Northeastern PA will receive little to no impacts from this system. However, if the low pressure forms in Virginia and moves northeast, then it’s likely nearly all of Southern PA up through East Central PA will see a moderate to even heavy snowfall.

        For those interested in timing, snow will start Monday Evening across Western and Central PA, and continue through the night. The snow will actually last a fairly long duration due to the original clipper system not giving up even after it transfers most of its energy. By Tuesday Morning light snow could move into Eastern PA but the best snow looks to be back in Central PA. Heading into Tuesday Evening, snow will likely have ended in the Western Half of PA with snow still possible in Central and Eastern PA. We are confident that by Wednesday Morning snow will be done falling in all areas, with some flurries left over in the Laurel Highlands to the NW PA Mountains.

        As we mentioned earlier, there are still a few things to be worked out with this system. Also, this snow will be a wet snow as it will fall with temperatures just below freezing. We will have our first call out Saturday at 5PM and preliminary snowfall amounts will be included. If you do not have our Facebook page liked click here with updates regarding this potential winter storm: Pennsylvania Weather Action Facebook Page! Stay safe everyone!



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!
