The National Weather Service in Las Vegas, Nevada issued a statement yesterday saying they had reached a record "dew point depression" of 129 degrees (or: low humidity of 1%) when their temperature was 107 with a dew point of -22 F.
They explain on their Facebook Page:
"Las Vegas' largest dew point depression ever recorded was set on June 27, 2011 at 129 degrees. The dew point depression is the difference between the air temperature and dew point temperature. At this time the relative humidity was 1%. The previous record dew point depression was 120 degrees set on July 2, 2007. This makes June 27, 2011 the driest day ever based on the dew point depression!"
Relative humidity readings below 10% were widespread over the Southwest yesterday, though the KLAS airport was the driest I could find on the Mesonet map.
Training thunderstorms and mesoscale convective complexes slammed West Virginia and Virginia yesterday, killing 14 people and dropping more than a foot of rain.
