The cold has finally arrived and winter-like weather is here to stay. January will be a much different month weather-wise than December and honestly a complete flip. Temperatures near average now (highs in 20s and 30s, lows in teens and 20s), until January 9th will lead to well below normal temperatures by Mid-January. Models have been consistently indicating this truly icy cold for mid-month for nearly three weeks.
Along with this cold, the potential for winter storms has developed, especially between January 9th-12th and that’s just the beginning. All three major models being the GFS (American), ECMWF (Euro) and GEM (Canadian), have all indicated the potential for a winter storm or even two in Pennsylvania between January 9th-12th. Will conditions be favorable? Yes, extremely favorable. A negative AO and MJO phase 8 will be in place both supplying the necessary cold air, as well as a neutral to negative NAO which supports the possibility of a coastal low pressure.
If cold air is as overwhelming as it is on the image above, the southern half of Pennsylvania would have the best shot at snow produced by a low pressure to the south. However, several cold shots will fly in beginning Sunday, bringing the lake effect snow potential sky-high.
That’s all for now, we will continue to monitor the threat(s) of a winter storm between the 9th and 12th.
We will be posting much more on our app regarding the expected weather such as exclusive videos and weather models. The app also offers a current conditions, interactive radar, local forecasts and much more so be sure to download it!
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!
