Dew point is measured as a temperature, reflecting when the atmosphere is saturated. On our weathercasts, we showcase a scale, created 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. On Tuesday and today, our dew point will register at 71, the oppressive range. Those in the Desert Southwest are accustomed to a “dry heat.” On Monday, Las Vegas set a record dew-point depression at minus 22. Relative humidity was 1 percent; the air temperature at 4:32 p.m. was 107.
