FXUS65 KVEF 081154 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 454 AM PDT Wed Jul 8 2026 .KEY MESSAGES... * Dry conditions and warming temperatures will continue through the end of the week. * Monsoonal moisture begins increasing this weekend, resulting in increased chances for showers and thunderstorms early next week. && .DISCUSSION...Today through Tuesday. High pressure builds aloft and temperatures are on the rise through the rest of the week. Afternoon high temperatures will top out between 5 and 7 degrees above normal and Las Vegas has a 40 to 50 percent chance of a high of at least 110 degrees each afternoon between Thursday and Saturday. Hot daytime temperatures combined with warm overnight low temperatures will result in widespread Moderate (Level 2 of 4) with pockets of Major (Level 3 of 4) Heat Risk for most locations. This level of heat will affect those who do not have access to sufficient cooling and hydration, as well as those who are especially vulnerable to heat related illnesses. The position of the high should maintain dry conditions and afternoon breezes, which prompt elevated fire weather conditions across much of the region today and tomorrow. A classic monsoon setup develops this weekend as high pressure becomes established over the Four Corners region and southerly flow advects moisture into the Desert Southwest. PWAT values of an inch or more cover areas along and southeast of Interstate 15 on Sunday, at which point the best precipitation chances will exist over high terrain in northwestern Arizona. Moisture increases and POPs spread north through the first half of next week, generally favoring high terrain where orographic lift favors thunderstorm formation. Finer details on timing and location of storms should become more apparent over the next few days. Other than storm potential, lowering heights aloft and the moisture influx should help lower temperatures by a few degrees. && .AVIATION...For Harry Reid...For the 12Z Forecast Package...Breezy south-southeast winds will set up later this morning around 8 kts, though can't rule out an occasional gust between 15 and 20 kts.
