(00:00:00) Todays weather in Las Vegas - Sunday - 17 May 2026 (00:00:18) Friday's Record Heat Milestone (00:00:42) Dramatic Temperature Drop Sunday (00:01:16) What to Wear Sunday (00:01:54) Safety and Timing This Weekend Las Vegas flips the script this weekend. Just Friday, Harry Reid International Airport recorded the first 100-degree day of the year — a milestone that arrived early, with May already running two and a half degrees above historical averages. Now, within 48 hours, a Wind Advisory takes hold.Starting Sunday at 2 p.m. and running through Monday at 5 a.m., the National Weather Service is warning of gusts up to 60 miles per hour. Sunday's high reaches around 90 degrees in the morning, but temperatures tumble fast once the advisory kicks in. By Sunday evening, expect the low 60s — a swing of nearly 30 degrees in a single afternoon. Monday's high drops further to just 78 degrees, roughly 10 below normal for mid-May.Practically speaking: Sunday morning is your best window to be outside. Light layers will do before noon. If you're heading out in the afternoon, pack a jacket — the wind will cut through a t-shirt immediately. Anyone driving a truck, RV, SUV with a roof rack, or any tall-sided vehicle should plan around the 2 p.m. to midnight peak-gust window. The National Weather Service has specifically flagged high-profile vehicles for this event.Outdoor plans for late Sunday afternoon should be reconsidered. Sixty-mile-per-hour gusts can move debris, reduce visibility, and make conditions genuinely hazardous. Monday morning the advisory lifts and conditions stabilise — but this is one of the more dramatic weather swings Las Vegas has seen this season.This episode includes AI-generated content.
