Nevada – Neon lights glow against a clear desert sky as Las Vegas starts MLK Day on the cool side, with crisp air settling across the valley before sunrise. Jackets feel welcome early, but the chill fades fast once the sun clears the Spring Mountains.
According to the National Weather Service in Las Vegas, morning temperatures sit in the low 40s before rebounding sharply. Afternoon highs climb close to 70 degrees under full sunshine. Winds stay light, keeping travel smooth along I-15, U.S. 95, and surface streets across the valley.
Conditions remain quiet tonight with clear skies and lows dipping back into the low 40s. That cooling pattern repeats into Tuesday morning, then quickly reverses as sunshine returns. Tuesday afternoon highs reach the mid-60s, continuing a stretch of mild winter weather across southern Nevada.
By Wednesday, clouds increase slightly, but temperatures hold steady in the low 60s. Outdoor plans remain favorable, though evenings cool quickly after sunset. With dry air in place, visibility stays excellent for drivers and travelers heading toward Red Rock Canyon or Lake Mead.
Thursday and Friday bring little change. Mostly cloudy skies mix with sunshine, and highs hover in the low to mid-60s. No rain is expected, keeping roads dry and travel impacts minimal. Desert nights remain cool, so layered clothing works best for long days out.
Looking ahead, longer-range outlooks point to near-normal precipitation and continued mild temperatures across the Southwest, while colder air remains locked farther east. For now, Las Vegas stays comfortably on the warm side of the winter pattern.
