When I'm wondering about weather folklore and historical events this is the man I go to. With more than 50 years of statistical and observational research, he's the dude! When it comes to lunar cycles, woolly bear caterpillars, insects, bugs, and animals, he tracks them, records them, and establishes ties to weather patterns. Only one person takes climatology to a level like this. He even has a lifetime achievement award from the National Weather Service for his devotion to data and science. His name is Steve Gottschalk by way of Lowden, Iowa. He's a knowledgeable and interesting man. I'm grateful to him for lending his unique perspective to the site. Steve's "wild" world of weather can be found regularly right here on Take it away Steve!

December 100 Years Ago

According to the state's climate records, December of 1922's average temperature was near normal with 24.0 degrees. Some northern stations in the state had 12 days with 0 degree readings while Keokuk had just 1 day. The coldest reading during the month was -25 at Decorah, Nora Springs and Rock Rapids on the 18th. The warmest reading was 65 at Thurman on the 29th.

The average precipitation for the month was 0.37" making it one of the state's driest on record. The greatest monthly total was 0.97" at Wescott and the least was a trace at 4 different stations. The freezing rain that fell on the 6-7th lasted for several days causing a lot of automobile and pedestrian accidents

The average snowfall for the month was 2.2" which was 4.0" below normal. The greatest monthly total was 8.0" at Milford and the least was a trace at 8 different stations.

Can Fergie The Cat Predict The Weather?

My daughter's family got a kitten on Christmas Day last year. She was yellow and white colored and they called her Fergie. When she got older she started running around the house and being wild on certain days. My daughter texted me when Fergie was acting up and I started keeping track in a journal. On the 18 days she was wild the weather was windy or there was some precipitation or both. She has a perfect record so far. Some times it's just hours before the event and other times, it's the day before. I will continue to keep track of her predictions.

Two Memorable December Snowstorms

The coldest decade was the 1980's with a monthly average of 22.1 degrees, this was followed by the 1870's average of 22.5.
