FXUS65 KVEF 091855 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1155 AM PDT Thu Jul 9 2026 .KEY MESSAGES... * Dry conditions and above-normal 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 Thursday. High temperatures will continue to be fairly steady and 6 to 8 degrees above normal into the weekend. Hot daytime temperatures combined with warm overnight low temperatures will result in widespread Moderate (Level 2 of 4) with small pockets of Major (Level 3 of 4) Heat Risk for most locations. A combination of dry and breezy conditions also prompt elevated fire weather conditions across much of the region today and tomorrow. High temperatures will begin to trend downward on Sunday but low temperatures will be trending higher with the increase in moisture. The center of the high will make to near the Four Corners Region on Saturday afternoon. Given the easterly flow, any convection over the Mogollon Rim may produce outflow that may push into Mohave County as early as Saturday evening. Overall, gusty outflow winds and dry lightning continue to be the primary threats for at least the first few days as forecast soundings display inverted-V patterns with moisture aloft and drier air near the surface. Orographic lift will favor storm formation over high terrain. Thunderstorms will be isolated on Sunday as instability will be fairly limited but coverage should increase across the area on Monday. The moisture will ebb and flow during the week as the center of high pressure shifts a little further north or south. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...
