On Friday, Las Vegas is expected to see warm conditions with light winds and seasonal afternoon highs. According to the National Weather Service, "Mostly clear skies exist across the region early this morning," though there is a chance of "a few showers and perhaps a lightning strike or two across the Sierra and Owens Valley regions this afternoon and evening." Conditions align with typical mid-May weather patterns for the area.
"Gusty southwesterly winds of 40-50 mph spreading from the Western Mojave Desert into Southwest Utah" are expected as a trough moves in over the weekend. Wind advisories are in effect, though the strength and duration of the winds remain uncertain. There is also a chance of brief showers along the base of the trough. After the weekend, "Ridging sets up over the region," leading to warmer temperatures. Las Vegas has a "63 percent probability" of reaching its first 100-degree day of the year on Thursday. Moderate heat risk is expected in desert valleys, with major heat risk possible along the Colorado River, as reported by the National Weather Service.
Harry Reid International Airport is forecast to experience shifting winds from the northeast to the south by late morning, transitioning to a southwest direction by mid-afternoon, with speeds decreasing overnight. "Winds will remain under 10 knots and will follow typical diurnal directional trends," and "FEW to BKN clouds aoa 15 kft filtering through the area." VFR conditions are expected to continue throughout the day, consistent with broader regional forecasts for southern Nevada, northwest Arizona, and southeast California. The National Weather Service requests that spotters report any significant weather or impacts as they occur.
