(00:00:00) Todays weather in Las Vegas - Monday - 18 May 2026 (00:00:45) Airport Ground Stops Sunday Night (00:01:11) Cold Front Drops Ten Degrees (00:01:37) Blowing Dust Tonight (00:02:02) What To Do Today (00:02:18) Las Vegas Monday Forecast Wrap Las Vegas weather delivered one of its sharpest swings of the season overnight. A powerful cold front pushed through the valley Sunday evening, bringing sustained winds of fifty to sixty miles per hour with gusts hitting seventy — enough to shut down multiple stages at the Electric Daisy Carnival and trigger ground stops at Harry Reid International Airport.After back-to-back days of 104-degree heat on May 11th and 12th, Monday's high forecast is just 78°F. That's roughly ten degrees below normal for mid-May, and it means the heat wave — at least for now — is over. If you've been waiting for a breather, today is it.But don't put the weather app away yet. The high wind warning runs through 5 a.m. Monday, and gusty conditions continue through the evening. Patchy blowing dust is expected tonight, with lows dropping to the low 50s in the outer valley and low 60s near the city. Visibility could drop in spots, and air quality will be poor in affected areas — especially relevant if you have respiratory sensitivities.Practically speaking: layer up this morning, secure anything loose outside, and stay alert for blowing dust if you're driving open stretches of the valley. Hydration still matters even at cooler temperatures. Today is manageable — just gusty. Enjoy the cooler air while it lasts.This episode includes AI-generated content.
