GFS Model Forecast For Sun AM

An approaching low moving across the Great Lakes and a developing off shore low will bring the threat for light snow to most of the Mid-Atlantic & NE this weekend. Most areas are likely to see coatings – 1″ of snow from Interior CT southwestward into SE PA. Areas further south and along the coast may mix with rain for a time, with temperatures near or above freezing, keeping accumulations to slushy coatings to about 1/2″…with the highest amounts likely on colder surfaces.

 

Why aren’t forecasted snow amounts going to be higher? Ordinarily an Alberta Clipper like this over the Great Lakes would provide more in the way of snowfall for the area (maybe 1-2″) but the secondary low development of the coast usually disrupts wind and precipitation fields between the lows, which is where the I-95 corridor happens to be in this case. Watch for forecast & alert updates this weekend!
