571 FXUS65 KVEF 162026 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 125 PM PDT Thu Oct 16 2025 .KEY MESSAGES... * Dry and pleasant weather conditions are expected through the weekend, with cool temperatures gradually returning to seasonal normals. * A weak system will bring increasing wind and a chance of showers toward the middle of next week. && .DISCUSSION...through early next week. Broad troughing will persist today across the region keeping temperatures well below normal but otherwise dry and pleasant. High pressure will gradually begin to build in Friday and into the weekend which will allow for a warm up trend, with temperatures returning to near normal levels by Sunday. A modest enhancement in northerly winds is expected Friday as the trough axis shifts east with the strongest winds favored along the Colorado River Valley, with the higher winds expected during the morning hours. Guidance has trended to favor stronger ridging early next week across the Southwest, with a fairly strong shortwave dropping through the PacNW and into the Northern Rockies Monday, mainly resulting in a slight cooling and enhanced surface winds Monday and Tuesday in our region. Winds will be highest across central Nevada, but should have very little impacts. Meanwhile, a fairly deep cut off low will be meandering off the west coast of Southern California, and is poised to eject inland by the middle of the week. This may spread increased cloud cover and some shower activity into the Mojave Desert by Wednesday and slightly cooler conditions, but uncertainty remains fairly high this far out. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Clear skies are expected through the TAF period. Winds today will remain light and generally less than 10 knots, favoring north to northeast directions through the afternoon and evening hours. Winds overnight will shift more to the north-northwest with speeds of 8-10 knots through daybreak Friday. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Clear skies with northerly winds are favored for the regional TAF sites. Surface winds of 5-10 knots will be common outside of the Colorado River Valley, while stronger winds with gusts of 15-25 knots are more likely near KIFP and KEED. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION/Aviation...Gorelow For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
