With respect to the storm next week, the European and the Japanese models have squared themselves against the GFS, GEM (Canadian), UKMET, NoGAPs and DGEX. The European has a stronger, broader trough of air coming, forcing and spreading the energy farther south, thus pushing it out to sea before winding it up. The other models have a sharper trough allowing the system to come north quicker. The GFS is usually the one jumping systems out (eg Sandy) but this time it's the Euro. Not surprisingly, the Canadian is the most vigourous of the models. It tends to blow things up quicker/more.
So making a predicition on this is a tough one. I am going to wait until tomorrow to see if the models converge.
