Our crazy nice November weather will come to an end later today with the passage of a cold front sweeping the state. Moisture has been streaming into the state ahead of this passing storm system with dew point temperatures noticeably higher around 60 degrees. In fact, you may have noticed various surfaces, like shaded pavement, being wet from having a temperature below the dew point and thus condensing water onto it. Having such warm and muggy temperatures for November is a bit rare as shown by the featured chart presenting dew point climatology by air temperature for Des Moines during November. Having dew point readings near 60 degrees is at the 95th percentile for temperatures that can support such dew points.
