Muggy weather returned over Labor Day weekend with humidity levels running more like what we would have expected in August. For Des Moines, the dew point on Monday was slightly higher than even the highest dew point for all of August. The featured chart shows the yearly combination of highest September versus August dew point. Points above the one to one line would represent years like this year with a higher dew point in September. This combination is somewhat rare and last happened in 1998.
