La Nina is here but it's on the weaker side as of September. We see this weak La Nina to peak now but get a second burst in December and January before moving to a neutral pattern Febraury and March. This weak La Nina means a colder winter for most of the nation and certainly much colder than last winter. The key to this winter will be how cold is the cold and how dominate will the Northern Jet (Arctic Jet) be vs. the moisture loaded Southern (Sub-Tropical Jet)?. Last year the Southern Jet was the big player off a massive El Nino but this winter that will not be the case most of the country. We expect an average swing of the NAO (North Atlantic Oscillation) but much more of a dip from the AO (Arctic Oscillation) bringing a few polar vortex periods and many Alberta Clippers.
The Edmonton Metro area will see above average snowfall in this La Nina winter. We will see below normal temperatures overall, with January coming in as the coldest month. Expect numerous snow days, but with smaller type events. Overall expect more snow than last year and your seasonal average as well.
