Storm Prediction Center Indicates Both Supercells and Bow Echos Possible Saturday

Estimated reading time:1 minute, 42 seconds

        The Storm Prediction Center has been discussing this threat since Tuesday Morning, and now only being three days out it’s time for us to address it. As many of you know, we will now be posting the Storm Prediction Center’s Maps with their key. Along with that, we will be quoting several areas of their discussion.

        With that said, we will also be including our thoughts about this event, so let’s get started. First of all, this will be a northwesterly flow type event. These events can be very interesting especially for Western and Central PA, where the SPC’s risk area currently sits. Damaging winds will be the greatest threat. Right now, we are leaning towards a strong line of thunderstorms forming over Lake Erie. If this occurs, they will then move over Northwest PA first, then the Pittsburgh area along with State College, then down into Southcentral PA in the Chambersburg and Harrisburg regions by the evening.

        The majority of the line in a way will be a bow considering its motion. This once again is why we think damaging winds will be the main threat. The Storm Prediction Center does state there are some differences in the models as far as the overall area that will be threatened (which there is). That really becomes the case in Southern PA. However in Northwestern PA and even in the Pittsburgh region, we are confident there will be scattered severe storms.

        Here is the area the Storm Prediction Center has labeled at risk for these severe storms. Keep in mind, veteran meteorologists came up with this map.



        Thursday, the SPC will be issuing their Day 3 Outlook for this threat, which will be much more in-depth. Also, we will have more confidence in the general area at risk.

        Stay tuned for that info tomorrow afternoon especially if you plan to be out and about Saturday. Be sure to like Pennsylvania Weather Action on facebook. If you do not have us liked, you can do that by clicking here! 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!
