FINAL CALL For Significant Snow & Ice Storm Tonight into Saturday

Estimated reading time:1 minute, 56 seconds

There is now the threat of a widespread ice storm in Central and Western Pennsylvania. While upper levels warm Saturday Morning, moderate precipitation will continue in many areas with surface temperatures well below freezing. Deep valleys will hang on to cold air the longest Saturday, with some areas not reaching the freezing mark until mid-afternoon.

Below is the RGEM for 4 AM Saturday Morning.

As you can see, while the overwhelming majority of the state is experiencing snow at this point, freezing rain is beginning over Southwestern PA. Here is the same model for 7 AM Saturday.

By 7 AM, freezing rain will overtake much of Western and Central Pennsylvania. At the same time or just before, a heavy band of snow will likely move through Eastern PA. Finally, here is what the radar could look like by around 10 AM.

Nearly the entire southern half of Pennsylvania is seeing freezing rain at this point, with some snow still persisting in Northeastern PA. This is because upper levels will take the longest to warm in Northeast PA.

There is the possibility that deep valleys in Central PA do not changeover to plain rain. In all other areas, this storm will likely end with a short period of rain. By Saturday Evening, temperatures will be well above freezing.

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!
