A push of warm and moist air has once again invaded the state making today feel more like summer than fall. The featured chart presents the climatology of near surface water vapor mixing ratio, which is a measure of the amount of moisture held in the atmosphere. The summer of 2010 has certainly seen more than its fair share of humidity as noted by the dominance of red in the lower plot. The grey filled area in the top plot represents the range of mixing ratio. It is interesting to see that the lowest values in the summer are still higher than the maxes in the winter.
