Sorry for the delay in providing updates, I have been actively tracking the storm but life has gotten in the way of posting updates. But do not fear, I will be with you throughout this weekend. (Sorry to my wife and daughter for disappearing to track this weekend.) This storm is lining up to be a classic for our area, with a key difference being the duration. In recent years our storms have been in and out in under 12 hours. However, this one looks to be a long duration event starting late Sunday evening and continuing through Tuesday morning. As a matter of fact, some models including the latest NAM run are indicating snow will continue through midday Tuesday.
Overall this storm will drop anywhere from 10-15 inches regionwide, with the potential for some areas to exceed 15″ depending on where banding sets up. By the way of example, the 3K NAM out to the end of it’s run at hour 60 has around 15 inches of snow for Long Island, and it is still snowing at that time indicating the chance for some areas to possibly hit 20″. However, at this time there is limited support for that outcome with only the Parallel GFS model supporting this outcome. The regular GFS and EURO models both are in the 10-15 range for our region.
I will keep you updated as more model runs come out later today and we start zeroing in on where the banding will setup.
