High Dew Points

This past weekend, especially in eastern North Dakota most people would describe the weather as humid.  In fact, several people described it as oppressive.  It was described as one of those terrible days with temperatures around 90 with 90 percent humidity, except, it wasn’t.  When the temperature was around 90 degrees this weekend, the relative humidity was in the upper 50s to around 60 percent.  The old saying it isn’t the heat, it is the humidity, should actually be it isn’t the heat but the dew point.  The dew point this weekend was as high as the mid 70s, common in the southeastern US in the summer. Mid 70s dew points are uncommon this far north, but certainly not unheard of.
