EUROPEAN SAYS MAJOR SNOWSTORM LOOMS FOR PARTS OF THE EAST...HEAVY WET SNOW INLAND FRIDAY NIGHT INTO SATURDAY....THEN RAIN CHANGING TO WET SNOW FOR COASTAL AREAS DURING SATURDAY AND SATURDAY NIGHT!!! The European is extremely dynamic and would say that a big wet heavy snowstorm looms large from the mountains of Eastern Tennessee and Western North Carolina, northward through West Virginia, the Western half of Pennsylvania and Western NY through Saturday morning. The 500mb is has a much more phased look to it than the gfs. I cant see the liquid amounts being produced but my guess is that it is significant for those areas. By 120 hrs we have a wrapped up bomb, less than 980 mb just east of 40 & 70. This is where I wish we could see where it is in between. It has a comma like structure that you would think would get most of SE NY and Southern New England during Saturday and Saturday night. The difference between the European and the GFS is the full phase with the northern stream as the trough lifts up. Unlike the GFS, the European never gets the southern part of the trough to far away and out of control so that it all lifts as one feature. Again I would like to see the precip maps with this to see just exactly how much liquid we are talking about here. By 120 hrs you would think given that surface that most of interior New England getting buried while the coast fights the battle between very cold air aloft getting drawn down against a 55 to 60 degree ocean. At least for New York City to Boston that battle will be critical in here. You want as much depth as possible in order for the cold air to overtake the other mitigating factors given the time of year. Now lets see if the 18z gfs catches on to this idea. Going to wait until tomorrow morning because of model volitility to decide whether to go on Noreaster alert. Id do it now but all the flip flopping back and forth still has me a bit nervous. And again let me be clear here, i am interpeting what the model is showing and not necessarily ready to forecast this. I may be ready soon..but not yet!
