FIRST CALL Snowfall Forecast For Sunday Snowstorm

        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.
