The forecast has chilly and even freezing low temperatures possible over the next few days. Typically, this would not necessarily be a big deal as the calendar is only at the end of April and climatology says we have a week or two to go before freeze risks substantially subside. This spring has been a bit different with plenty of very warm days and the growing season has gotten off to a very fast start. When this happens, the NWS will issue such alerts like Frost Advisories and Freeze Warnings even though climatology says freezing temperatures are more common than not. The featured chart presents an IEM estimate of the number of growing degree days since March for an Iowa statewide estimate. The 2026 total certainly stands out and comes in fifth largest since 1893.
