Looks like we've resurrected a very old thread here ... but that's OK.
Southern and Central regions of Alberta get chinooks ... a warm wind that blows in over the rockies. (Google it ... it's a pretty interesting weather phenomena.)
Olds is approximately midway between Calgary (50 miles south) and Red Deer (40 miles north)
The local school division is aptly named the "Chinook's Edge Regional School Division".
We get MOST of the benefits of the warmer temperatures, but don't have to endure the high winds. Recently it has been around +10° C (50°F) in Calgary, +5°C in Olds, and -10°C in Red Deer.
As a result, many of us joke that there is now way that we would want to live north of the "Bowden Border"
These chinooks are typically identified visually by a band of clouds called a "Chinook Arch", which is a clearly defined by an area of clear blue sky to the west, with quite dense clouds to the east ...
The dividing line on the west side is usually very sharp and distinct, while the clouds seem to disperse rather gradually ... with blue skies again in the east.
The whole cloud bank formation is usually centered on the hifhway #2 corridor, and is probably about 50 miles wide or so. If you're inside of the arch, you can expect warm air.
Temperature changes occur fairly suddenly and dramatically, making Calgary one of the hardest places in Canada to accurately predict the weather in.
There are times when the warm air remains aloft ... 2 or 3,000 feet above the ground ... which sorta teases us. LOL
I've attached some pictures ...
