Overview
- Southern Nevada has entered a stretch of unseasonable warmth likely to persist for much of December, according to the National Weather Service.
- Daytime highs are forecast in the low 70s with overnight lows in the upper 40s to low 50s across the Las Vegas Valley.
- Temperatures are expected to run 10 to 15 degrees above normal through at least the end of the week, with no records projected to be broken.
- A ridge of high pressure parked off the Southern California coast is driving the warm, stable, and dry pattern over the region.
- The dry spell could leave the month without measurable rain, even as 2025’s total at Harry Reid International Airport stands at 4.96 inches, the most since 2019 and above the 4.18-inch average.
