As expected, yesterday was the hottest of the heatwave with readings approaching or tying all-time records.

For the 3rd time, Las Vegas, NV has topped 117 degrees, tying the hottest temperature ever reached at McCarren Intl Airport. The other two times, 1937 and 2013.

Las Vegas turns it’s attention to number of consecutive days of 110 degrees or above.

The exceptionally powerful upper ridge has driven surface temperatures to the max but forced air pressure to lower and so this hot but also thin air has forced many flight cancellations yesterday and likely today.
