After experiencing temperatures in the twenties (degree centigrade) yesterday, just over night, the clouds came in the covered the Bow Valley with snow again. The golf courses had started to turn green, and the bears had started to wake up, now everything is once again a wintery white.

This is great news for skiers and snowboarders, as Lake Louise, Sunshine and Jasper Marmot Basin are still open and going strong. There are some great last minute deals to get out here, and the ski hills are very quiet this time of year!

Why such a rapid temperature change?

Rapid temperature changes are quite normal here in the Canadian Rockies. They are due to Chinook winds which usually begin with a sudden change in wind direction over the Pacific Ocean, towards the west or southwest, and with a rapid increase in wind speed.

These winds move across B.C. towards the Rockies. As these winds move across the barrier of mountains (the Rockies), they often push a band of clouds in front of them, which are visible on the western horizon. The curvature of the Earth makes this band of clouds appear like an arch. This is often a distinct feature of a Chinook.

These winds are not as obvious in the summer, when the temperature change is not so dramatic. But for now, the post-Chinook situation means great conditions for skiers and snowboards, and an awesome wrap up for a fantastic season.
