A strong upper level jet is developing across the mid latitudes of the northern Pacific (left hand side of figure 1 above). This jet is expected to undercut the blocking high across the Bering Sea. As this occurs, the blocking high will weaken and allow the polar vortex across northern Canada to be dynamically forced southwestward across Alaska and the northeast Pacific by early next week (left hand side of figure 2 below). The main consequences of this altered pattern will be higher pressures aloft across much of the United States. These higher pressures will act to drive the cold arctic air mass back into northern Canada and Alaska next week (right hand side of Figure 2), bringing a return to a mild air mass across the region.

So overall, if you like snow and cold it appears we will continue experience winter conditions across the area through Saturday. Thereafter, it appears temperatures will warm back above average next week. The figures below display the 8 to 14 day outlooks from the Climate Prediction Center. Notice that the Much of the continental United States has high probabilities of experiencing above average temperatures during this period. There are also enhanced chances for above average precipitation during the 8 to 14 day period. This would likely fall mainly as rain as we progress into a mild pattern.
