December Monthly Record

Posted: 13 Dec 2021 03:10 PM

Last week, the IEM daily feature showed a eight day forecast from a model predicting record high temperatures for the month of December on Wednesday. That forecast is appears to be panning out with official NWS forecasts now above all time record highs for the month for places like Des Moines and Ames. The featured chart presents IEM computed monthly record highs for Ames. The present forecast is 70 degrees, which would top the 68 degrees shown on the chart. Similarly, Des Moines forecast is 70 degrees which would top its record of 69 degrees for the month. While the temperatures will feel amazing, very strong and dangerous wind gusts are also forecast for later in the day and overnight on Wednesday into Thursday. There will also be a threat of severe storms as well. The present hope is that we will at least avoid a tornado outbreak on the scale of what happened last week over states near and including Kentucky, but ingredients for such an event will sadly be in place again over/near Iowa this time.
