310 FXUS65 KVEF 101742 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1041 AM PDT Thu Jul 10 2025 .KEY MESSAGES... * Hot and dry conditions will likely continue through the weekend and into early next week as ridging persists across the region. && .DISCUSSION...Today through the Middle of Next Week. Ridging will remain generally over the area through the forecast period, though the exact placement and intensity of the ridge will vary at times. Through the weekend, long range ensembles are in decent agreement that the area of high pressure will remain somewhere over southern California. Slightly above normal height anomalies will remain over the region through Saturday which will result in above normal temperatures, light winds, and mostly sunny skies. Sunday through early Tuesday, ensembles show the ridge building eastward which will raise temperatures a few degrees. This should be the hottest time period with high temperatures 5-8 degrees above normal and Major (level 3 to 4) HeatRisk possible in desert valley locations in Southern California and Southern Nevada on Monday and Tuesday. After Tuesday, heights fall slightly as the ridge potentially interacts with an easterly wave. This wave will knock back temperatures a few degrees but will likely remain above normal. In addition, if this wave is able to push far enough westward, increasing moisture is possible through southern Nevada and western Arizona. There is a low chance for precipitation Tuesday afternoon but low confidence if rain will occur and what impacts may result. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Northwest winds with intermittent gusts to 15 knots will continue into the early afternoon before becoming light and variable after 20Z. The typical southwest-to-west winds will develop around 00Z, and occasional gusts to 20 knots can be expected through mid- evening. Light and variable winds return by daybreak, followed by a more typical wind progression tomorrow, with northeast winds in the late morning, southeast winds in the afternoon, and southwest winds in the evening. Speeds tomorrow are expected to remain 8 knots or less, except for random gusts to 15 knots during the afternoon due to intense heating. VFR conditions will prevail through tomorrow at the field. Reduced slantwise visibilities are possible along the Beatty corridor due to smoke from a wildfire burning on the Nevada Security Site. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Conditions at the Las Vegas area terminals will be similar to those described for Harry Reid, except winds at KHND will favor a more south-to-southwest direction tomorrow. Elsewhere, northerly winds of less than 10 knots are forecast for KBIH through tomorrow morning before turning southerly tomorrow afternoon. Gusty westerly winds will persist at KDAG, with a typical decrease expected during the late morning and afternoon hours. In the Colorado River Valley, southerly winds with occasional gusts to 25 knots are expected during the late afternoon and early evening, followed by light winds overnight. VFR conditions will prevail through tomorrow across the region. Reduced slantwise visibilities are possible across portions of southern Nevada and far eastern southern California due to smoke from a wildfire burning on the Nevada Security Site. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Nickerson AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
