Can you compare the 1967 “Big Snow” with the blizzard of 1979?

Dear Tom,
Can you compare the 1967 “Big Snow” with the blizzard of 1979?

Dear Stephen,
The 23-inch Jan. 26-27, 1967, Big Snow is Chicago’s benchmark snowstorm. The snow began falling shortly before 5 a.m. on Jan. 26 and ended just before noon on Jan. 27. Strong northeast winds up to 53 mph created huge drifts, paralyzing the city for more than a week. The Jan. 12-14, 1979, blizzard produced 20.3 inches of snow and at the time was the city’s second heaviest snow. Snow began early in the afternoon Jan. 12 and finally ended about 2 a.m. Jan. 14. Winds were not strong during the height of the snowfall, but blizzard conditions set in as the snow waned. Today, the blizzard of ’79 ranks as the city’s fourth heaviest snow, surpassed by the 21.6-inch 1999 New Year’s storm and the 21.2-inch Groundhog Day blizzard in 2011.
The 23-inch Jan. 26-27, 1967, Big Snow is Chicago’s benchmark snowstorm.
