FIRST CALL Snowfall Forecast For Sunday Snowstorm

Estimated reading time:1 minute, 29 seconds

        This storm is very similar to this winter in more than one way. Up until about 60 hours out, nearly all models indicated a potent winter storm impacting the region. After that, models completely shifted and throw a curve ball. This is why we wait to predict amounts until inside of 60 hours. No, we’re not calling off this storm as a whole in any way and in fact this storm was one minor dynamic shift away from being a monster. That has been the theme this year with the exception of the January Blizzard. Let’s get into the details on timing and accumulations!

        First of all, this storm will not only be a grass-type of event as bridges could become slippery as well. Light snow will move into Southern PA Sunday Morning. By the afternoon light to moderate snowfall will begin to spread into Eastern PA including the Philadelphia region. Sunday Evening will bring the heaviest snow to Southeastern PA and during this time is when we expect the most snow accumulation to occur as the sun is going down.

        A general 2 – 4″ is anticipated across much of Central and Eastern PA as well as the Laurel Highlands. Heavier snowfall of 4-6″ is likely in Southeastern PA in and around Philadelphia and just south of Allentown. While this snow will primarily be on grassy surfaces, temperatures will fall below freezing Sunday Night and could possibly bring a freeze-up on the roadways.

        With how models have been during this storm, anything is still on the table and we will continue to provide the best forecast we can with the latest data available.

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!
