Severe Thunderstorms Expected Sunday & Monday; Flash Flooding & Damaging Winds Possible

Estimated reading time:1 minute, 22 seconds

After what has seemed like a long break from severe weather, strong to severe storms will target the state Sunday and Monday. Much of the western half of the state has experienced abundant amounts of rainfall over the past few days due to non-severe, slow moving storms. Suburbs of Pittsburgh, Johnstown, and Altoona have all seen flash flooding over the past few days. With the ground waterlogged in many areas, it will not take much more rain for significant flash flooding to occur.

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!
