FXUS65 KVEF 150228 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 730 PM PDT Tue Apr 14 2026 .KEY MESSAGES... * Clear skies and warming temperatures expected through tomorrow before gusty winds and cool temperatures return late-week. && .DISCUSSION...Through Monday. Temperatures will increase a few more degrees today and tomorrow as heights aloft increase. Tomorrow's highs will be within a few degrees of normal for mid-April, which for Las Vegas means highs in the low 80s. A change in the weather pattern arrives on Thursday as an area of closed low pressure, currently located off the coast of British Columbia, dives southeast into the Great Basin. The primary concern with this system is wind. Southwesterly prefrontal winds ramp up in the Mojave Desert while northwesterly postfrontal winds start to increase in the southern Great Basin on Thursday morning. These winds include gusts between 35 and 45 mph, the strongest of which should occur over high terrain. Winds remain elevated and gradually shift north on Thursday night as the front moves south. The strongest winds with this system are expected to occur on Friday in the Colorado River Valley as a favorable north to south pressure gradient develops. There is a greater than 80 percent probability of wind gusts reaching 40 mph in that area and a 40 to 50 percent probability of gusts reaching 58 mph in a localized area near Bullhead City. Will continue to monitor model trends and assess the need and timing of wind-related headlines. Besides wind, cold air and lowering heights aloft bring a 10 to 15 degree temperature decrease between Wednesday and Friday. Most moisture associated with this system remains the north of the forecast area, but there is a 20 to 40 percent probability of light precipitation in Lincoln County on Thursday and early Friday. Snow levels fall to between 2000 and 3000 feet on Thursday night as cold air moves in, meaning a dusting of snow cannot be ruled out. Temperatures will rebound and dry conditions return as ridging builds again this weekend, but breezy southerly winds may continue for some of the area. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Light winds of less than 10 knots are expected through the overnight hours following typical nocturnal drainage patterns. Southerly winds will increase in the late morning and early afternoon hours with gusts to 20 knots after 22z. Gusts will ease after dark with southerly winds continuing. Skies will be mostly clear tonight before increasing high clouds move in Wednesday evening. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Winds across the region will generally follow typical daily directional patterns with speeds around 5-10KT into Wednesday morning. By early afternoon Wednesday, southwesterly winds ramp up across the Las Vegas Valley, with gusts to 20-22KT expected on at least an intermittent basis. Additionally, across the western Mojave Desert, including KDAG, westerly winds will hover between 10-15KT through early morning, with a lull expected through mid afternoon before gusty winds return. Otherwise, VFR conditions prevail with skies gradually clearing tonight before additional high clouds arrive Wednesday evening. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Meltzer AVIATION...Phillipson/CO For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
