West Central Saskatchewan can expect to see a cooler and drier fall than normal, according to our regional meteorologist, Drew Lerner.

Drew said his data is showing him that in approximately 10 days, the warmer bias that the region has seen for much of the last couple weeks will start to disipate. As of right now there is a big pool of warmer water off the coast of Alaska and a similar situation off the US West coast. Usually when it is set up like that, that will set the stage for a northwestern flow pattern which would put an end to the warmer conditions felt by the region that will see some parts of West Central Saskatchewan see temperatures as high as 25 degrees celcius with a healthy dose of sunshine going into this weekend.

Lerner noted what has been happening recently in the region is contrasting air masses, milder and cooler air coming from Alberta, and warmer air in the northern US plains and southern Saskatchewan south of highway 1 has led constant mixing and unstable conditions. Once the northwestern flow occurs as he predicts the region should see calm, dry conditions as the warmer air gets pushed further into the US.

Drew also noted that as we move from later in fall into the winter the coldest air will shift east towards Manitoba, Ontario and Quebec, unless we get a negative phase of Arctic Oscillation, then we would see that colder air shift west. Lerner reiterated that he won't know whether the Arctic Oscillation will be positive or negative for a few weeks.
