Back to the point, the arrows on the images on the chart above show where this warming event is occurring. At the moment, we see the strongest activity placed between the 40N and 70N latitude areas. This corresponds roughly to the area between the southern Great Lakes and Mid-Atlantic to northern Canada when looking at the North American continent. Because this is a stratospheric warming event, I do anticipate a body of colder air to transition from the upper atmosphere down to the surface, just as what happens in a winter stratospheric warming event.
The question is, where will the cold air end up? Remember that the 40N - 70N area includes the rest of the world, and the effects of stratospheric warmings are not limited to North America. A quick glance at ensemble projections of the mid-level atmospheric height anomalies beyond the 10 day period shows a troughing pattern over the Great Lakes. This could clear the way for not only cooler weather created by the troughing pattern, but also, if the atmosphere cooperates, colder weather being shifted to the surface from this stratospheric warming event. But at of right now, this is all educated speculation.
