Coastal Storm Is Here. Your Driving Speed Should Be Like Cooking BBQ: Low and Slow. Safe Travels!

Posted on
Well the coastal storm is here. Hope many of you got out early safely and that many who have to drive today are going to take it slow and easy today if they have to drive during the day. As for the storm, it looks like a heavier snow band could elevate snow potential from the mountains of western MD to south-central PA and into northeastern PA. Here’s my snow total forecast from last night, with potential heavier local amounts to the 3-6″ range near where the heavy snow band is:
Snow Totals From Coastal Storm By Location (Through Early Thursday Morning):
