Days till one inch

Posted: 04 May 2023 05:30 AM

After drought plagued much of Iowa over 2022, we had a very wet cold season, but frozen soils limited infiltration and totals during the cold season are difficult to offset large deficits during the growing season. So we are now squarely into the growing season and drought concerns are quickly increasing. The featured map presents the number of days to go back in time before accumulating at least one inch of total precipitation. This map nicely shows the areas of the state that have recently been very dry. The good news is that there are chances of rain in the forecast, but how widespread and significance remain in doubt. The rains of 2022 were very fickle and highly variable, which appears to be how the growing season of 2023 is starting off as well.
