Why is it that south western British Columbia never gets caught in a deep freeze or a cold snap the way the Prairies do in the winter?
The reason why British Columbia never really gets into a deep freeze for long periods of time is because the average wind flow for B.C. during winter is southwesterly. This almost guarantees a mild pacific airflow over British Columbia. Typically, air off the Pacific is also wet air that provides ample rain in the winter.
