Our stretch of mostly dry and amazingly nice fall weather continued over the weekend with only a few stray showers putting an isolated damper on otherwise near perfect weather. Having dry weather this time of year is generally positive for farmers as it helps harvest progress and quickens the dry down of for the crops not yet ready for harvest. The featured chart presents the IEM estimated statewide precipitation totals each year between 19 September and 3 October. The total this year is at about the 90th percentile over the period of record and not too much below the 2020 total. The 2019 value of nearly 5.5 inches certainly sticks out on this chart and that harvest season still brings back horrible memories to Iowa farmers.
