462 FXUS65 KVEF 150739 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1239 AM PDT Wed Jul 15 2026 .KEY MESSAGES... * Chances for terrain-based, afternoon and evening convection will continue through the end of the week. * Near-to-slightly above normal temperatures will continue through midweek, with temperatures decreasing slightly heading into the weekend. && .DISCUSSION...Through Tuesday. Another round of monsoonal thunderstorms is on tap for tomorrow. Convective initiation will depend on how much cloud cover drifts into the area from Arizona and Utah tonight, and how fast it clears out in the morning. There is still plenty of moisture, with PWATs over one inch for most of the Mojave Desert. However, instability is still not impressive, generally between 500 and 800 J/kg, with around 10 knots or less of shear on forecast soundings. Most storm activity should start off over the mountains and high terrain with the assistance of orographic lift. Localized heavy downpours are possible under the storms themselves, and outflow boundaries may lead to gusty winds far from the parent storms, along with additional storm formation. High resolution guidance shows some potential for a secondary round of storms in the late afternoon and evening over northwest Arizona triggered by outflow from activity over the Mogollon Rim. Persistent monsoonal moisture advection brings daily thunderstorm chances each afternoon, with increasing risk for heavy rain and flash flooding Friday and this weekend as lower levels of the atmosphere moisten. Today and tomorrow will be the hottest days of the week as high pressure builds overhead. Afternoon highs will be in the upper 100s to low 110s in most valleys around the Mojave Desert with overnight lows in the 80s to low 90s. Hot daytime temperatures and warm nights offering little relief combined with monsoonal humidity result in Moderate (Level 2 of 4) Heat Risk for most areas, with pockets of High (Level 3 of 4) Heat Risk including the Las Vegas Valley both days. There should be some improvement late week as moisture and precipitation potential increase and temperatures fall several degrees. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Southwesterly winds of less than 10 knots continue through the night, becoming variable tomorrow morning. Similar southwesterly winds return in the afternoon, and although speeds should remain less than 10 knots, a few gusts of 15 to 20 knots cannot be ruled out. There is a 15 to 30 percent chance of convection over high terrain in the afternoon and evening, but activity should remain outside the vicinity of the terminal. Outside of the valley, thunderstorm activity is once again expected in the Mormon Mesa and Peach Springs corridors. Temperatures reach above 100 degrees between 17Z and 06Z. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Expect mostly quiet weather tonight, aside from an low chance of outflow boundaries from Arizona causing changes in wind direction. Another round of convection will begin tomorrow afternoon across much of the region, generally favoring high terrain. Storms should stay out of the vicinity of most terminals aside from KBIH, but gusty outflow winds have the potential to reach any terminal in the region. Outside of storms, winds should generally follow typical daily patterns. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION/AVIATION...Meltzer For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
