An Extreme Heat Warning is in effect for Las Vegas, with temperatures in the desert valleys expected to reach the triple digits today and Thursday. Highs will be 5 to 10 degrees above normal, creating a major heat risk in the area. According to the National Weather Service, this is due to "potentially dangerous heat" that could affect anyone without proper precautions.
Winds are expected to increase from Thursday through Saturday, creating conditions that could lead to wildfires. The National Weather Service says “prolonged dangerous fire conditions and increased fire spread potential will develop.” On Thursday, “HREF shows high probabilities (80% or more) for relative humidities below 15% and wind speeds over 20 mph across southern Nevada and western Arizona most of the afternoon.” Similar or worse conditions are possible on Friday and Saturday. At Harry Reid Airport, light winds and VFR flying conditions are expected, with some afternoon gusts possible.
Temperatures are expected to decrease, with "highs in the 90s Sunday and Monday, perhaps even into Tuesday." Winds will also calm as an upper-level low moves into place. The National Weather Service advises spotters to "report any significant weather or impacts according to standard operating procedures."
