Here is my preliminary call for the 10-12 January 2011 event:
The operational models have not necessarily been agreeing with each other as to the storm’s track, but each model has had their own consistencies in producing snowfall along the East Coast, so I decided to venture a first guess. A final map (and maybe an intermediate map) will be issued as the event gets closer.
It will be interesting to see if the GFS (and NAM) snow-enhanced zone north and west of Richmond, VA will verify as it seems to like having the secondary low over the southern Midwest a little better than the ECMWF does. Mixing will be a problem in NC, and that will likely need to be adjusted a bit. I haven’t thrown in anything above 8″ yet, but that may become a concern when making the update.
