**ALERT** MAJOR SNOW & ICE EVENT LIKELY FOR MOST OF VA MD…. eastern WVA… DELMARVA STARTING WED PM LASTING INTO FRIDAY AM
This event has a good chance to bring the largest snow accumulations of the season to much of these areas along with the potential for significant ice and possible ice storm conditions in some portions of Virginia. The only area right now which is not appear to be impacted by this event will be Southeast Virginia / Hampton Roads.
Unlike the last several events WxRisk thinks this is not going to be an event which mainly impacts the Pennsylvania northern Maryland NJ NYC southern NY states and New England. (which was the case with January 28 February one1 and to a lesser degree with February 1).
This will be a long duration event. The key issue is the Arctic boundary which at the beginning of the event will be located to the north of the Pennsylvania Maryland border on Wednesday afternoon and evening.
The GFS /American model and the European model do NOT agree regarding the movement of arctic front Wednesday night and Thursday. The GFS model is slower to move the front further to the south so all of its significant snow and ice only impacts the northern third of Virginia, Maryland, Delaware, Pennsylvania, New Jersey New York City and the northern half of West Virginia. The European model generally handles shallow cold air penetration from Pennsylvania New York into the Middle Atlantic region in a much more consistent and scientifically sound manner than the GFS model. So for this forecast we are going to rely upon the European model.
If it turns out that the European model is wrong and the GFS model is correct then most of the snow and ice will be significantly further to the north only impacting the northern 25% of Virginia Maryland Delaware and much of Pennsylvania New York and Southern New England once again.
So assuming that the European model is correct …..this is how the event plays out on Wednesday night into Friday morning
