Snow lovers don’t mind to hear “winter storm advisory in affect”. School children enjoy hearing “two hour delay tomorrow”, or better yet, “schools are closed”.

The cold air and wind from the Jet Stream move south out of Canada, hence “Alberta” and the winds come through that wrinkle fairly quickly, hence “clipper”.

Virginia temperatures have been below freezing for many days in January and February may not be much warmer.
