The National Weather Service in Las Vegas has forecasted ongoing hot weather to persist through midweek, with temperatures expected to maintain their rise today and Tuesday. "Broad high pressure built in across the Western US," is largely to blame, according to an early morning discussion posted by the National Weather Service. Minor relief in the form of very modest cooling could occur thereafter, but temperatures in many areas will continue to reach the 90s and lower 100s.
For locals seeking respite from the heat, the forecast is mixed; while isolated thundershowers might cool down Lincoln, Esmeralda, and central Nye Counties slightly, the showers are expected to bring "gusty winds and very brief light rain" rather than a substantial temperature drop. Currently, the Extreme Heat Warning issued remains valid through Tuesday, and the National Weather Service has considered extending this to Wednesday, particularly for eastern Inyo County, as they continue to monitor the trend.
Looking forward toward the latter half of the week, "heading into Thursday, flow aloft over the region will transition to southwesterly ahead of a trough taking shape over the West Coast," the National Weather Service states. Any cooling will be subtle, as temperatures are predicted to stay around 5 to 8 degrees above normal. Over the weekend, there is a chance temperatures will climb again, which could trigger further periods of extreme heat.
From an aviation standpoint, Las Vegas will see typical winds following diurnal patterns, but these might become variable in the presence of any outflow from northern convection. The National Weather Service warns of "variable and briefly elevated and gusty winds" as a result. The forecast also anticipates that VFR conditions will prevail, with ceiling heights above 12,000 feet. For the weather enthusiasts, several climate records are potentially at risk, with daily high temperatures nearing previous records set in recent years as indicated by the comprehensive table provided by the National Weather Service. Spotters across the region have been put on notice to report any significant weather or impacts according to standard operating procedures.
