Las Vegas, NV – The desert is waking under crisp, blue skies this morning, the Strip bathed in early sunlight as a light breeze moves through the valley. After several chilly starts, southern Nevada is finally turning a corner toward a warmer, calmer stretch — a welcome shift for early December travelers and residents.

According to the National Weather Service in Las Vegas, temperatures are expected to climb steadily into the weekend, reaching near 65°F by Sunday. Mornings will remain cool, dipping into the upper 30s and low 40s, but daytime highs will feel mild, ideal for outdoor events, hiking, or local travel. Winds stay light, keeping dust and visibility issues to a minimum.

The warm, dry pattern holds strong through at least Tuesday, with no precipitation in sight and clear skies dominating across Clark County. That stability comes as much of the country braces for Arctic cold and snow farther north — a sharp contrast that makes southern Nevada one of the few mild-weather zones heading into mid-December.

For travelers returning from Thanksgiving trips, roads and airports across the Las Vegas Valley remain clear with excellent driving conditions along I-15 and U.S. 95. Expect chilly dawns and warm, pleasant afternoons perfect for early holiday shopping or outdoor lights displays.

Five-Day Outlook (Las Vegas Valley):

  • Friday: Sunny, high 62°F, calm wind.
  • Saturday: Sunny, high 65°F, low 45°F.
  • Sunday: Sunny, high 65°F, low 46°F.
  • Monday: Sunny, high 68°F, low 47°F.
  • Tuesday: Mostly sunny, high 70°F, mild breeze.
