Saturday Morning: When the upper air pattern is there, you need to beware!

Good morning, as a follow up to yesterdays post, we have a favorable upper air setup for late next weekend and even all of Christmas week. This increases the chances for cold,snow and potentially a white Christmas. There will be up to two storm threats Christmas week, but lets focus real quick again on the threat I discussed yesterday for late next weekend.

I explained the ingredients necessary for a east coast winter storm in the last post when we take a look up to 18,000ft in the atmosphere. For today, lets look at surface projections for next weekend from three different models.

GFS
















Canadian



















European
















All three major models are hinting at a storm developing late next weekend. The exact details still need to unfold, but I am discussing this threat because the upper air pattern supports it. Thus, the potential is real this time for a colder storm. All due to how the ingredients below end up coming together..

















More to come.
