Spring Dew Points

Posted: 04 Jun 2015 05:42 AM

While an IEM feature a few weeks back showed that the maximum reported dew point for the year to date was one of the lowest in recent years, the actual average dew point continues the recent trend of above long term average value. The featured chart displays an IEM computed average dew point reading for the Des Moines Airport for the spring season of March, April and May since 1970. The trend line for this period is upward with 13 of the past 18 years above the long term average.

Good = 17
Bad = 13
Abstain = 12
