On Wednesday afternoon, Chicago officially passed 53° for the first time since Oct 31, 2018, topping out at 57°F. That marks 132 consecutive days below 54°F, which is the second longest “below 54” streak since records began in 1871.
A deep low pressure system near 970 mb broke some records in Colorado with 80 MPH winds and a blizzard in Denver, and showed a distinct, vast commahead structure this afternoon on satellite and radar images. The system, known as a Bomb Cyclone for its rapidly intensifying low pressure, also includes a severe blizzard in Rapid City, South Dakota.
