Decorah Monthly Precip

Posted: 22 Sep 2023 05:30 AM

Yesterday's Feature mentioned the expansion of "D4" classification drought over the state of Iowa. Far northeastern Iowa was one of the two locations that got a newly designated D4, which included Decorah, which is the subject of today's featured chart. The chart presents the monthly precipitation totals over the past 20 years along with the long term mean at the bottom. This chart nicely hints at what likely saved the crops from a total disaster in the area, that being a wet cold season prior to this dry summer. Totals for November 2022 through May 2023 were close to or above average. So with this year's crop done and significant drought in play, we will likely again need a wet cold season to recharge the soil moisture.
