Las Vegas started the day on the comfortable side, with clear skies and temperatures sitting in the low 60s this morning. That pleasant sunshine will push afternoon highs to around 87°F, but the easy-going weather will not last. Readings are expected to spike through the week, with triple-digit heat looking likely by late weekend into early next week. Winds stay mostly light across the valley and forecasters do not expect any measurable rain during this stretch.
Rapid Warm-Up Through Next Week
According to the National Weather Service, the official forecast calls for highs near 92°F on Thursday and around 99°F on Friday. Saturday and Sunday are projected to top out near 100–101°F, before temperatures jump into the low to mid 100s Monday and Tuesday, with forecast highs of about 104°F Monday and 106°F Tuesday. A strengthening ridge of high pressure is expected to shove temperatures well above what is typical for mid May and to broaden the area facing heat risk. If you have outdoor work or big weekend plans, start thinking about shade, water and air conditioning now, because they are about to become non-negotiable.
What This Means For You
Forecasters put the odds of the valley hitting triple digits at roughly 40% on Sunday, climbing to about 90% by Monday and Tuesday. If those trends hold, the chance of official heat watches or warnings later on goes up as well. Clark County maintains a running list of cooling stations and heat resources for residents who need a safe, air-conditioned place to ride out the hottest hours. Make a plan now, check in on older neighbors or anyone without solid cooling at home, avoid heavy outdoor labor during peak heat, keep water close at hand, and never leave children or pets in parked cars, even for a short errand.
Stay Updated
There are no heat watches or warnings in effect for the Las Vegas Valley yet, but confidence is growing that heat risk will expand, and officials could issue Extreme Heat Watches or Warnings later this week. We will update this page if advisories change; for a deeper dive into how this heat pattern set up, see our earlier heat outlook. In the meantime, stay hydrated, keep an eye on the forecast, and try to shift workouts or other strenuous activity to the cooler morning or evening hours. According to the National Weather Service.
