NEVADA — The desert sky glows clear over Las Vegas this morning, but crisp December air lingers as early risers face temperatures near 39°F. The first week of December brings a steady chill to the Mojave, a seasonal reminder that even the desert gets its share of winter bite.
According to the National Weather Service in Las Vegas, calm, dry conditions will hold through midweek with sunny skies and highs in the upper 50s to low 60s. By early evening, however, the warmth fades fast — temperatures drop into the upper 30s to low 40s, with light northwest breezes adding to the chill.
No precipitation is expected this week, but a few gusts near 20 mph Wednesday could make morning commutes brisk, particularly for those heading along I-15 and Route 95. Drivers should watch for early-morning haze and localized frost on windshields in outlying neighborhoods such as Summerlin and Henderson.
By Thursday and Friday, a gentle warming trend will lift highs toward 61–62°F, perfect for early holiday errands, outdoor dining, or setting up winter lights before another round of cooler air arrives this weekend.
Meteorologists say the pattern remains stable — no rain or snow expected through Sunday — but the air will stay dry and chilly, especially after sunset.
Five-Day Las Vegas Outlook:
- Tuesday: Mostly cloudy early, then sunny, high 58°F, low 40°F.
- Wednesday: Sunny, high 61°F, low 38°F.
- Thursday: Sunny, high 58°F, low 39°F.
- Friday: Sunny, high 62°F, low 43°F.
