THURSDAY DECEMBER 12 - ALBERTA CLIPPERS
In the mid-19th century,
vessels with tall masts and built for speed were called "clipper
ships." Meteorologists have their own version of the "clipper
ship," a type of storm that's fairly common during the winter.
I'm referring to the so-called "Alberta
clipper," a fast-moving low-pressure system that's born on the
eastern slopes of the Canadian Rockies, in or near the province of
Alberta. These often race
southeastward following a track
that eventually brings them close to our
area. But given the dry region that they come from and their
fast movement, Alberta clippers usually bring us only a small
accumulation, maybe an inch or two at most.
Sometimes when these storms get off the East Coast, they
intensify, but by that time it's usually too late for more
significant accumulation here. All we get is an increasingly strong
northwest wind that brings in lots of cold air behind the storm.
