The weather this month has been nothing short of crazy. Tuesday saw yet another day of large temperature gradients in the state, heavy rainfall and tornadoes. The humidity levels over the warm side of the state were again at record levels for October. The featured chart presents the hourly extreme dew point observations based on period of record data for Ottumwa (southeast of Des Moines). The chart shows a number of hours this month with tied or set records including the highest overall value of 73 degrees tied with 1954. There is optimism in the forecast that this craziness is about to end after one more day on Wednesday.
