On the 4th anniversary of the famous Blizzard of 2011, also known as Snowpocalypse, Chicago is in the midst of yet another blizzard, although this one might not seem quite the same as that blizzard. What makes this different from that storm?
The Blizzard of 2011 was predicted nearly two weeks in advance. Snowfall rates reached 3-4" per hour, and the snow fell in less than a 24 hour period. Total snowfall was 20.2" at O'Hare Airport, good enough for 3rd on the all time list.
Four years later, The Blizzard of 2015 is in full force. This storm was once predicted to only bring 3-6" of snow to the area. This is a long duration snow event, with total snow time of over 30 hours by the time its all said and done. While totals could definitely approach the 20" mark in some areas, snowfall rates will not reach 3-4" per hour in this storm. The main reason for the blizzard criteria is because of reduced visibilities (1/4 mile or less) for a minimum of three hours.
As of noon, O'Hare is reporting 8.5" of snow with MUCH MUCH more on the way. Lake effect snow appears to kicking it downwind of the lake as well. Expect most areas to finish in a 12-16" range with some isolated 18" or more totals definitely possible.
If you have to drive, please be safe. Drive slow, and allow yourself extra time. Stay tuned to this blog as well as my Facebook page and Twitter for the latest.
