Las Vegas is bracing for a slight drop in temperatures this Wednesday, July 17, with highs reaching around 104°F (40°C). While the heat remains intense, hazy skies and breezy southwest winds—gusting up to 25 mph—will continue to sweep across Clark County, adding a layer of discomfort. Meanwhile, moisture is gradually moving into southern Nevada, introducing a slight risk of isolated mountain showers and storms.
Thursday brings a noticeable shift in the weather pattern. Humidity levels will rise, and there’s a slight chance of scattered afternoon thunderstorms. Temperatures are forecast to hover near 100°F (38°C), which aligns with seasonal averages for mid-July in the Mojave Desert.
The most dynamic day appears to be Friday, when humidity increases further, and the likelihood of showers and storms strengthens, particularly in the afternoon and evening. This storm activity will help push daytime highs down to about 99°F (37°C), offering a brief reprieve from the persistent summer heat.
Saturday maintains a slight storm potential, but drier air is expected to return to the Las Vegas Valley early next week, easing conditions once again as the monsoonal pattern shifts.
