Humidity will replace Las Vegas ‘blow-dryer’ with hot and sticky

Updated August 7, 2018 - 10:27 pm

Increasing humidity and a slight chance of rain will arrive at the tail end of an excessive heat warning in the Las Vegas Valley this week, according to the National Weather Service.

An excessive heat warning remained in effect until 10 p.m. Wednesday, meaning that temperatures will be dangerously high during the day and into the evening. The valley tied its daily record Tuesday with a high of 111, matching the temperature recorded in 1994.

The Clark County Department of Air Quality has extended a smoke and ozone advisory through Wednesday because of haze from particulate material drifting in from California wildfires.

Smoke can irritate respiratory diseases and contribute to ozone. Ozone exposure can cause coughing, wheezing and shortness of breath, the county said.

The increasing humidity will make the Las Vegas Valley feel hotter on Wednesday, which has a forecast high of 108, even as temperatures begin dropping. There is a 10 percent chance for showers through Saturday, the weather service said.

“Today will be the last day that we feel like the blow-dryer,” meteorologist Clay Morgan said Tuesday. “The temperatures come down, but that humidity is going to go up. It’s just going to be very uncomfortable.”

Thursday’s expected high is 107, while Friday and Saturday will see temperatures drop to 105. Low temperatures for the end of the week will hover around 86, according to the weather service.
