From heat to snow: Western Canada split by stark pattern polarities
The West will experience a bit of all four seasons this week, depending on locale, thanks to the position of the jet stream.
Western Canada will see a significant temperature and pattern divide this week with extended summer-like weather continuing for parts of B.C. and Alberta, in contrast to early winter-like weather in the north and east where snow squall watches and winter storm warnings are in place.

A ridge in the jet stream will continue to fuel the record-high temperatures across B.C. and Alberta for much of this week. Some of the latest 25°C temperatures are likely to be recorded this week for stations in B.C.
Stormy weather has developed in parts of Northern Canada where cooler air has finally settled.
Several days of system snow and snow squalls are forecast across the N.W.T. and Iqaluit along with cooler air migrating south, bringing in cool, scattered showers and snow flurries across Manitoba.
Lake-effect snow flurries are even possible in the Interlake Region mid-to-late week.
In between this transition zone are two different air masses, resulting in intense wind gusts across much of Saskatchewan for the next few days with gusts 50-80 km/h forecast.
There is potential for relief in B.C. from the drought conditions after Oct. 20 with a more typical mid-fall pattern expected to move in with cooler and wetter weather. Uncertain whether this will be a temporary pattern change or if this will take us into a more extended period of cool and wet weather.
On the Prairies, a dry pattern will continue to dominate across western areas, while eastern sections can expect more unsettled conditions with rain and snow showers at times. The eastern Prairies can expect November-like temperatures dominating for the next 10 days.
