The overall trend of below-normal temperatures that occurred in Iowa during September continued into about the middle of October in most areas, and longer in some eastern locations.
However, other than the locations that reached the lower 30s back on Sept. 13, more widespread freezing temperatures this year didn’t occur until early to mid-October. Into late October, there were still some locations that had not dipped as low as 32 degrees.
Warmer-than-normal days became more common during the latter part of October, especially in the western half of Iowa. Into late October, average monthly temperatures were running a few degrees above normal in about the western half of the state and ranged down to slightly below normal in many eastern Iowa locations.
