JOESTRADAMUS: FRIGID PATTERN BUT IS THE PATTERN TOO COLD FOR SNOW? (DECEMBER 26, 2017)

Weather Models Frigid Indecisive About Snow Chances

With the mother load of cold air spreading across the Eastern US over the next week or so, the question of snow is a rather confusing one. Weather models are displaying a certain sense of indecisiveness for a number of reasons. The main reason is that you have a hugely strong polar jet stream that is so dominant that there is little room for weather systems to develop in any important way.

EUROPEAN MODEL FRIDAY DECEMBER 29 2017

The European model as well as the GFS & Canadian models and for that matter the NAM model all have this upper air look through Friday morning. The polar jet is dominating everything and while there are disturbances moving along it, there is no room for development. The disturbance in the Northern Plains has a chance to bring some snow here on Saturday but not all models agree with this idea. The European & the Canadian model offer the most bullish view on this.

EUROPEAN MODEL SATURDAY MORNING DECEMBER 30

The European model strengthens the trough as it swings east with the bulk of the development well offshore but it still digs far enough west to produce some snow here Saturday. With bitter cold air this is likely to have snow rations of 15-20 or even 20-1.
