Brand-new 18z Euro ensembles with another slight shift southward with the snow:

The 18Z ensembles only go out to 1 PM Tuesday, but I saw the ensemble mean snow map, and it shifted the snow shield slightly south again. Here are all 50 maps from the Euro ensembles for next Tuesday for the period 7 AM to 1 PM, and the 3rd image shows the projected storm locations/strengths at 1 PM next Tuesday. There is still uncertainty, of course, and it will continue to evolve, so I will keep posting updates.
