Near-Record Breaking Temperature Drop After the Storm Hit
What a crazy day of weather on Wednesday, December 15th. We went from wearing shorts and T-shirts in mid-December to bundling up in winter gear in just a matter of hours.
At 3 PM on Wednesday it was 73* in Cedar Rapids, setting a new record high for not just December 15th, but for the entire month of December. Until Wednesday, it had never reached 70* in Cedar Rapids in the month of December. The prior daily record was 55* set in 1957. The prior all-time December high temperature for Cedar Rapids was 69* set in 1998.
Waterloo also hit 73*, smashing the former record of 54* set 98 years ago in 1923. (records date back to 1895) This was also the first time that temperatures surpassed the 70* threshold in the month of December for the city. The previous all-time December high temperature was 67*, which occurred three times, most recently on December 3, 2012.
Then, the storm hit. At midnight in Cedar Rapids, it was 28.* It dropped an amazing 45* in nine hours. That’s the fifth-largest temperature drop in a nine-hour period since records began tracking this info in 1972, according to information from the Iowa Environmental Mesonet.
In Waterloo, it also reached the peak of 73* at 3 PM and then fell to 29* by midnight on 12/16, that's a temperature drop of 44* in nine hours. That’s the second-highest temperature drop in a nine-hour period since records began recording this information in 1949.
