Las Vegas, NV – The desert is waking up to a crisp, clear Friday morning as southern Nevada slides into a stretch of postcard-perfect weather. Skies remain bright and dry across Clark County, but travelers returning home after the holiday will notice one change — cooler air settling in each night.

According to the National Weather Service, today’s high reaches around 70°F under full sun, followed by a cool evening low near 47°F. The air stays calm, with light winds shifting northwest. The pattern continues through Sunday, with highs easing down into the mid-60s by the end of the weekend.

Saturday and Sunday both bring mostly sunny conditions, ideal for outdoor plans or post-holiday drives along I-15 or US-95. Evenings, however, turn brisk. Temperatures will dip into the low to mid-40s, creating that “winter in the desert” chill that tends to surprise late-season travelers.

Meteorologists expect this quiet stretch to hold through early next week, but early-December models hint at cooler air sweeping south by midweek. No rain is forecast for Las Vegas yet, though northern and central Nevada could see a few high clouds tied to that same pattern.

Residents can expect ideal sightseeing weather by day but should keep jackets handy after sunset. The coming week’s chill may be a small preview of the winter pattern building across much of the West heading into early December.

Enjoy the calm before the colder winds arrive — how are you spending your sunny weekend in Las Vegas?
