13 First Alert Weather Forecast | Sunday morning, July 31, 2022

LAS VEGAS — Scattered heavy thunderstorms have prompted Flash Flood Warnings across the Desert Southwest today, including parts of the Las Vegas valley. Locally heavy rain will cause isolated flash flooding, alongside the chance of severe wind gusts past 50 mph in the vicinity of heavy downpours, as well as the threat of dangerous lightning. Storm chances continue this afternoon and won't diminish until Sunday evening. Rain cooled air will keep afternoon temperatures in the 80s in parts of Las Vegas that have seen downpours, highs elsewhere will be limited to the mid 90s. Smaller storm chances linger on Monday, and then go down again on Tuesday, as highs climb to the upper 90s under a partly cloudy sky. The humidity drops a bit Wednesday and Thursday, so the forecast is dry then for the first time in over a week (and hotter, with highs at 103° those days). Humidity creeps back Friday and next weekend, delivering a 20% chance of storms and highs around 100°. Nighttime and early morning low temperatures will by in the low 80s during this stretch, with 70s in areas that see scattered downpours.
