An excessive heat warning is set to expire Wednesday night for the Las Vegas Valley, and a chance of showers will be back in the forecast as the weekend approaches.
While the excessive heat warning for the Las Vegas Valley should expire at 10 p.m., the National Weather Service said an excessive heat warning for western Clark County — including Sandy Valley, Indian Springs and the western county border — should last through 10 p.m. Thursday.
There’s a 20 percent chance of showers Thursday and Friday afternoons. That chance will rise to 30 percent Friday evening, the weather service said. Rain is more likely to fall over the Spring Mountains during that time, but the valley might see a stray shower or two as well.
