Dew point is measured as a temperature, reflecting when the atmosphere is saturated. On our weathercasts we showcase a scale, designed by meteorologist Dave Nussbaum, for dew point ranges. During Fall, Spring and Winter, our dew point readings may register between 40 and 49 degrees reflecting super dry conditions. We're comfortable when the readings are 50 to 59 and the humid range is between 60 and 64 degrees. On Tuesday and today our dew point will register at 71 which are in the oppressive range. Those in the Desert Southwest are accustomed to a "dry heat." On Monday, Las Vegas set an all-time record dew point depression at minus 22 degrees. Their relative humidity was 1% and the air temperature at 4:32 PM was 107 degrees.
