The National Weather Service expects hot, dry conditions in the Las Vegas Valley over the next few days and issued an excessive heat watch that’s effective from Tuesday morning to Wednesday evening.

It’s the third excessive heat watch this month; one was issued Aug. 3 and the other Aug. 14, according to weather service meteorologist Kate Guillet.

An excessive heat watch is issued when conditions are favorable for dangerous temperatures, Guillet said. It switches to an excessive heat warning when temperatures are expected to reach dangerous levels, she added.

Sunday hit a high of 107 degrees with 5-10 mph winds. The weather service said the light winds will continue throughout the week.

The high on Monday should climb to about 107, the weather service said, and Tuesday and Wednesday will reach 108.

Temperatures will fall slightly in the latter half of the week, with highs near 106 forecast for Thursday and Friday, the weather service said.

As of Sunday, Guillet said, this August is set to be one of the driest on record, with only a trace of rain at McCarran International Airport earlier this month. There is a potential for higher-than-normal precipitation in early September, she added.
