022 FXUS65 KVEF 291650 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 950 AM PDT Sun Jun 29 2025 .KEY MESSAGES... * Slow warming trend continues into early next week. Hottest temperatures will be on Monday and Tuesday. Temperatures cool to near normal by midweek. * Increasing moisture will bring a slight chance for thunderstorm activity next week, mainly for Mohave County, with much of the rest of the area remaining dry. && .DISCUSSION...through the end of next week. Typical summer heat will prevail through early next week as high pressure builds across the area. With heights slowly rising, temperatures will gradually climb each day, rising 3-7 degrees above normal by Monday and Tuesday. Despite being warmer than the daily averages, it`s still pretty typical heat for late June and heat risk largely remains in the moderate category. A few pockets of major heat risk develop in parts of Mohave County and the Colorado River Monday and Tuesday, but remain too brief and spotty in nature to justify any heat products. As moisture pushes into Arizona midweek and heights begin to fall as a low pressure system offshore approaches, temperatures will moderate Tuesday onward and return to near normal values. Meanwhile, as the Four Corners high orients itself in a more favored location for moisture advection, along with a weak low over southern California strengthening the southerly flow, expect increasing thunderstorm activity across Northwest Arizona Tuesday onward. A fairly sharp contrast to drier conditions are expected further west thanks to a slight southwesterly component of the flow advecting drier air into the region, but storm chances look to spread into the eastern Mojave Desert and perhaps Lincoln County Wednesday and Thursday. Main concerns will be the potential for some dry lightning initially, followed by more typical summer like downpours and gusty winds midweek onward. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds will gradually veer around to the southwest through the morning hours. By early-to-mid afternoon winds will have settled in from the southwest with sustained winds approaching 10 knots and occasional 15 to 20 knot wind gusts. These breezy southwesterly winds will continue into the evening hours with speeds decreasing later tonight while winds continue to maintain a southwesterly direction through early Monday morning. Temperatures will exceed 100F between 19z and 04z, with a peak around 106F. VFR conditions and clear skies will prevail through the TAF period. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...With the exception of the western Mojave Desert, where winds will favor a westerly direction through the TAF period, southerly breezes are expected across the region through the afternoon and into the evening hours. Sustained speeds will be in the 8 to 12 knot range across the area with wind gusts around 15 to 25 knots. Winds will decrease overnight with winds shifting to their typical nocturnal directions. VFR conditions and clear skies will prevail through the TAF period. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Outler AVIATION...Stessman For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
