Halloween 1991 Blizzard Ushered in Record Cold
The Halloween 1991 blizzard brought more than major snowfall to Minnesota and the Upper Midwest. Assistant State Climatologist Pete Boulay says that storm system ushered in some early arctic air:
“The low temperature on November 4th in the Twin Cities was three-below zero and there were below zeroes throughout central and parts of southern Minnesota. And that was probably the defining moment of the storm – was how cold the air was behind it. Those records might stand for a very long time.”
Boulay says the snow that was melting froze up and created bumpy, washboard-like road conditions.
