750 FXUS65 KVEF 091719 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 919 AM PST Sun Nov 9 2025 .KEY MESSAGES... * Breezy north winds will result in choppy waves on Lake Mohave today, otherwise dry, mild weather and warmer than normal conditions are expected across the region through the middle of next week. * A trough of low pressure will bring gusty winds, cooler temperatures, and increased precipitation chances to the region during the second half of the week. && .DISCUSSION...through Saturday. Breezy north winds will linger down the Colorado River Valley again today as ridging builds over the area. A Lake Wind Advisory has been issued for Lake Mohave due to 15 to 25 mph sustained northerly winds resulting in waves up to 3 feet. This advisory will go into effect at 4 am PST/5 am MST and will run through 4 pm PST/5 pm MST this afternoon. The aforementioned ridge will persist through the middle of the week, allowing for dry conditions and warmer than normal temperatures to continue across the region through the middle of the week. Our streak of warm, tranquil weather will come to an end as we head into the second half of the week and a trough moves through the area. While there is still some uncertainty regarding the finer details of the forecast, ensembles are slowly converging on a singular solution. The latest guidance shows gusty southwesterly winds picking up on Thursday as this system approaches the West Coast. Precipitation may begin as early as Thursday for the western portions of our forecast area, spreading across southeastern California into southern Nevada and northwestern Arizona as early as Thursday afternoon. Precipitation chances will continue through Friday as the trough pushes into the region with chances slowly tapering off over the weekend as trough moves through and clears out. Exact precipitation amounts will depend on the trajectory of the moisture plume associated with the trough as well as how much of this moisture is intercepted by mountains. In addition to gusty winds and increased precipitation chances, this system will also bring cooler temperatures to the region with temperatures dropping around 10 to 15 degrees from Thursday to Friday as this trough moves into the area. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds will become northeasterly around 18-19Z, with sustained speeds of around eight knots, and an occasional gust to 15 knots not out of the question. Winds will then shift to light southwesterly after sunset. VFR conditions will persist. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Winds will be generally light and diurnal across the region with the exception of the Colorado River Valley, where KEED and KIFP will see sustained north winds of 15 to 25 knots with gusts of 25 to 35 knots through sunset. Weaker winds are expected overnight into Monday morning. VFR conditions will persist. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Stessman AVIATION...Morgan For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
