Research Continues For The Upcoming Winter…

While still a little over a month from the release of our official annual Winter Outlook, we’re deep in research mode. This morning, we wanted to provide you with some updated model data, just for fun- all centered on meteorological winter (Dec. through Feb.).

UKMET- warm look with a stout southeast ridge in place.

European seasonal- warm look for the east though one could argue this would feature a warm start/ cold finish scenario (perhaps partly due to the warm SSTs in the eastern Atlantic).

Canadian seasonal- not only a cold look, but quite stormy as well. Plenty of high latitude blocking would force arctic air southeast into our portion of the country with an active storm track.

CFSv2- this would be a warm winter for the majority of the country as widespread ridging dominates.

The SST configuration remains an intriguing one. Despite the majority of data above in the warm camp as of now for the upcoming winter, this is the type setup that would likely force a predominant central/ eastern trough for the bulk of winter. The two areas we’re most focused on at this point? The central PAC and northeast PAC. Warmth across the north with cooling beginning to take place east (relative, of course, to the sea surface temperatures in the central PAC) strongly argues for cold to set up shop across the central and into the east. Let’s keep an eye on this over the next 4-6 weeks to see what, if any, changes take place. Should things remain relatively unchanged across the Pacific, we’ll likely see seasonal data begin to trend colder and colder for the upcoming winter.

(Our official detailed Winter Outlook with temperature and snowfall forecasts across the country will be out in mid to late October).
