Sioux City Precipitation Woes
Posted: 30 Jun 2022 05:13 AM, Views: 241
The Sioux City area remains one of the driest in Iowa and the weather on Wednesday was par for the course this year with a record high temperature of 100 degrees and completely missing out on limited rainfall chances overnight. The featured chart presents year to date precipitation totals for Sioux City with the 2022 value coming in fourth driest on record. Note that the 1891 total is omitted due to missing data for the month of June 1891. The 2022 value is even slightly below the 1988 total, which was an epic drought year for Iowa. Rain chances continue to be in the forecast, but it remains to be seen how much of this rain will fall over northwestern Iowa.
