The thermometer is expected to jump three to five degrees above normal in the upcoming week, sending Southern Nevada on a hot spell into the three-day Labor Day weekend.
The National Weather Service said that heat warnings will be issued if highs are expected at 108 degrees or higher starting Monday. The high for Monday is projected to reach 106 degrees, but that could change within a day, forecasters say.
Normal daytime temperatures are 101 to 103 degrees. Daytime highs are expected to range from 104 to 108 degrees in the coming week.
Some humid air will try to work its way back into the southwest, especially northwestern Arizona and Southern California, but no thunderstorms are expected in the Las Vegas Valley at this time.
Las Vegas has has 66 days of summer temperatures in the triple digits, in contrast to 72 days last year, the weather service said. Our highs this coming week are expected to tie or break that record.
With 108 degrees possible a week from today, Las Vegas may set record-high daytime temperatures for this summer.
