Alberta Clipper and
Blizzard (2)
Surface
Map
qWhen the Clipper cyclone forms and move southeastward across Canada and into the Great Lakes region, a new arctic front moves southward to the west of the low-pressure center.
qBitterly cold airs can be found behind this front.
qAlberta Clippers produce less snow than Colorado cyclones, typically two to five inches.
qMost of the snow forms in air lifted along and over the advancing arctic front.
qStrong winds to the northwest of the cyclone are again driven by the pressure gradients between the arctic high pressure and the cyclone center.
