A strong “Saskatchewan Screamer” whipped up wicked weather across much
of the United States in mid-January 2022, leaving a swath of snow and
wind damage in its wake. The fast-moving low-pressure system developed
over Saskatchewan, Canada then dropped below the border on January 13,
bringing up to 12 inches of snow in northern North Dakota and western
Minnesota. Des Moines, Iowa was buried under a whopping 14.3 inches of
snow as the stormed screamed southward, bringing heavy snow to parts of
Missouri, Arkansas, Tennessee—and tornadoes to Florida—before pivoting
northeastward to roar across the Mid-Atlantic and Northeast. According
to The Weather Channel, the heaviest snow totals from the January 13-17
storm fell in northeast Ohio, northwest Pennsylvania, and western New
York. They report 27 inches of snow in Ashtabula, Ohio and 23.4 inches
near Kenmore New York.

The Moderate Resolution Imaging Spectroradiometer (MODIS) on board
NASA’s Terra satellite acquired a true-color image of a swath of snow
painted by the robust winter storm. The band of visible snow is
centered on the I-95 corridor, starting just north of Atlanta, Georgia
and covered parts of Georgia, South Carolina, Tennessee, North Carolina
and Virginia. Heavy cloud hangs over Kentucky, West Virginia, Ohio, and
western Maryland.

A “Saskatchewan Screamer” is a nickname for a fast-moving low-pressure
system that sweeps southeast out of the Canadian province of
Saskatchewan, typically carrying snow, strong winds, and cold air along
with it. If a similar system develops to the west, over the province of
Alberta, it is known as an Alberta Clipper. Move the origin to the
east, and it can be called a Manitoba Mauler.
