Lead Forecaster Josh Adams

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!

February Will Be Chilly; But Will Snow Finally Show Up?

To begin with, this article will be more technical than normal. This winter started off with temperatures near average in December. Though, you were probably wondering why it never snowed when it was cold and why it always rained when it was warm. We often turn to the NAO and AO when we think of winter. However, neither of those factors really played a big role in December. The teleconnection that dominated the pattern was the PNA. If you don’t know what the PNA is, it’s no big deal. All you need to know is when the PNA is negative,…MORE...

Light Snow Event Thursday For PA, Nor’Easter for New England

We are watching two areas of low pressure systems this week that will lead to our potential snow event on Thursday. One will be dropping out of Canada in the form of a weak clipper system, while another area of low pressure develops in the south and eventually heads northeast. Where these two systems merge off the coast on Thursday, is what makes the major differences between model guidance and also our snowfall amounts. The quicker and further south these two systems merge, the more likely it is our state gets into a more note-worthy snowfall, especially Northeastern PA. The…MORE...
