Staggering snow pile-ups in Canada after unprecedented weekend blizzard

With this latest storm, the measured central air pressure hit 954 millibars on early Saturday morning. This amounted to a 54 millibar drop in less than 48 hours (h/t The Weather Channel). It turned into a powerful storm, with the same report pointing out that the one-day snow total in the Newfoundland city of St. John's reached 35 inches, which is close to the average snowfall the city sees across the entire month of January.
