It was hotter in Reno on Wednesday than it was in Las Vegas.
The high of 104 was easily a record for the date, beating the 101 first set 59 years ago and again in 1983 and 2000. Vegas topped out at 102.
Winnemucca matched its high for the date with 104, Carson City's 101 was 3 degrees above its previous July 30 record, set in 1978, and Wells hit 100 for a second straight day, beating its 2000 high of 98.
Wednesday assured Reno of its warmest July ever on the heels of a record-setting June.
Blistering days and warm nights combined for an average July temperature of about 79 degrees, slightly above the average temperatures of last July, when the city's hottest temperatures in history were recorded at 108 degrees. Last July previously was the hottest on the books, which date back to 1888.
"I thought it was going to be awhile before we topped that,"said Kelly Redmond of the Western Regional Climate Center in Reno.
A record-hot July following a record-hot June is a rare back-to-back event, the experts said. June's average temperature was 71.6 degrees, beating out the 71 degrees of 2000 and 1918.
This month, every day since July 3 has been at least 90 degrees, with nine days over 100.
Thursday's highs were expected to be well into the 90s, but just shy of 100 because of increasing clouds.
The day also was expected to see a return of afternoon and evening thundershowers with some packing heavy rain and possible hail.
A flash flood watch was in effect south of Carson City and in the Sierra south of Lake Tahoe.
