Widespread Severe Thunderstorms Likely Sunday; Damaging Winds, Hail & A Few Tornadoes Expected

Estimated reading time:1 minute, 8 seconds

        We have been warning our followers for several days about this threat. Details are especially coming into focus now that we are just three days out. Here is what we know as of Thursday Evening.

        A low pressure system moving across the Eastern Great Lakes will partner with a cold front, sweeping through the area Sunday Afternoon into the Evening. CAPE will top out near 2,000 J/kg, and the lifted index will be in the range of -5 to -6 across much of Central and Eastern PA. All mentioned factors support the development of widespread severe thunderstorms.

        There will not be as much cloud cover as originally expected, opening the door for more instability in the atmosphere. Furthermore, storms will be moving from west to east ahead of the cold front. Timing will be important because the location of the front will determine the location of the storms. Where the storms are located in the late afternoon/early evening will be the area at the greatest risk for severe thunderstorms.

        Here is our updated Severe Thunderstorm Threat Map (with key below it), along with a Main Risks Graphic, take a look!

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!
