LAS VEGAS (KTNV) — Hot, hazy and slightly humid conditions will stick around for southern Nevada with an Excessive Heat Warning in western Clark and southern Nye counties from 10 a.m. Sunday though 8 p.m. Monday. The warning impacts areas like Pahrump, Indian Springs, Barstow, and Amargosa Valley. Temperatures in the Vegas valley will hit around 108° Sunday and Monday under mostly sunny conditions. We're also dealing with some smoke from California wildfires, which leads to unhealthy air quality for sensitive groups. Monsoon moisture is still in place for the region keeping an isolated storm chance at 10% for the valley and 20% for the local mountains. We'll see cooler air move in by Wednesday bringing temperatures to the low 100s and upper 90s through Saturday.
