Overview
- Most areas will be hot and mostly sunny Friday before humidity rises across the country this weekend.
- Forecasters say the main window for scattered showers and thunderstorms is Saturday afternoon and evening into Sunday with spotty storms possible earlier.
- The Storm Prediction Center has placed limited areas in a slight (level 2 of 5) risk for severe storms north of Route 30 while other local offices warn storms could produce hail, damaging gusts, heavy rain and frequent lightning.
- Southern Nevada faces an extreme heat episode with highs near 106 in Las Vegas and sustained hot conditions expected through the weekend and into next week.
- Meteorologists link the change to a building ridge that heats Friday, then a cold front meeting increasing low‑level Gulf/subtropical moisture to fuel hit‑and‑miss convection and higher humidity that may keep daily storm chances and higher heat indices into next week.
