Slightly cooler, but hot temps remains in Las Vegas Valley

This week’s heat wave is over, but hot weather will continue through the weekend and contribute to an ozone advisory in the Las Vegas Valley.

Friday’s forecast has a high of 102 degrees, according to the National Weather Service. The breezy winds that buffeted the Las Vegas Valley on Thursday died down overnight and should stay calm through the weekend.

The Clark County Department of Air Quality issued an ozone advisory for Saturday and Sunday. The hot weather for the weekend, along with other pollutants, may trigger ground-level ozone pollution in the Las Vegas Valley, it said in a news release.

Ground-level ozone is a main ingredient of urban smong and builds up during the day due to strong sunlight, hot temperatures, gasoline and chemical vapors, polluntants from cars and wildfires. Ozone can cause coughing, sore throats, chest pain and shorness of breath.

Saturday and Sunday should see morning lows near 80 and highs of about 105. Monday’s high should reach 105, the weather service said, and Tuesday’s high will drop to 103.

The high for Independence Day on Wednesday should be 102.
