Are you cold yet? Frigid Arctic air finally arrived in the Midwest and East Coast.
For those of you who were wishing for a real winter, be careful what you wish for. Temperatures in Minnesota dropped to -29˚ degrees. Other Midwestern temperatures are theoretically warmer but with the wind chill factor, they range from -20˚ to -40˚F (- 29˚ to -40˚C for our Canadian readers).
The Alberta Clipper has arrived with a cargo of cold.
It’s odd to name a miserable weather event in the middle of the prairies after a boat, but when it was named, clipper ships were one of the fastest forms of travel at that time. These beautiful ships were named for speed, rushing through the ocean “at a fast clip.” Known for swiftness rather than size, they carried tea, spices, passengers, mail and other particularly profitable cargos.
Clipper seemed the ideal name for the fast windy storms that roared in from Canada and could cause temperatures to plunge overnight. Alberta clippers became notorious for their cargo of cold.
An Alberta Clipper is defined as a very fast moving low-pressure system born in that Canadian province. It then shoots southeast and slams the Midwest. This course keeps them hundreds of miles away from any moisture source, so typically they don’t deposit huge snowfalls just high wind and extreme cold.
This storm is further south than many, since less than 10% go south of the Great Lakes. It may start dry, but once it hits the lakes, it will carry a blizzard of “lake effect” snow east to the eastern Midwest, Mid-Atlantic and Northeastern states. Then, once it hits the relatively warm moist air over the Atlantic Ocean – look out!
According to experts, this is just the beginning. More storms should follow.
It’s strange. For such a friendly country, Canada can sure send us some horrible weather. We should be grateful, however, that this storm is coming from Alberta province. You should see the Alberta Clipper’s cousins—the Manitoba Maulers and Saskatchewan Screamers.
