A significant storm system now developing over the northern U.S. Rockies will continue to organize over northern Wyoming tomorrow (Friday). The storm will track toward northwestern Ontario by Sunday, producing a band of moderate to heavy snow up into the southern Prairies.
The heaviest snowfall for southern Alberta will fall late tonight into early Friday, then mainly Friday over southern Saskatchewan and Friday night through Saturday as we head into Manitoba.
The combination of wind, cold and snow will lead to periods of blizzard-like conditions over close to the U.S. border.
Currently digesting the newly released ECMWF seasonal model forecast for the winter, which is updated on the 8th of each month.
I will say that the new ECMWF model update is NOT predicting an El Nino for this winter, but near or slightly above neutral, which is in line with other forecast models.
I will discuss what the ECMWF shows in Friday's blog.
Arctic air will pay a brief visit to southwestern Canada early this coming week.
