600 FXUS65 KVEF 261742 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 942 AM PST Wed Nov 26 2025 .KEY MESSAGES... * Dry and mild weather will continue through Friday with breezy north winds in the Colorado River Valley today. * A pattern shift will bring cooler temperatures to the region over the weekend. && .DISCUSSION...through Tuesday. Breezy north winds will linger down the Colorado River Valley for one more day before the pressure gradient relaxes as a ridge of high pressure settles over the area. These northerly winds will peak between Laughlin/Bullhead City and Needles, where 15 to 20 mph sustained winds gusting to 25 to 30 mph are expected. While the magnitude of these winds remains well below Wind Advisory criteria, they will be enough to produce 1 to 2 foot waves on Lake Mohave this afternoon resulting in hazardous boating conditions for small water craft. Outside of these breezy north winds in the Colorado River Valley, dry, mild, and warm weather will continue across the region through Friday. A shortwave will begin to erode at the upper-level ridge on Thursday and Friday as it moves through the Pacific Northwest before digging southeast into the Four-Corners Region and ejecting into the Central Plains. This shortwave will open the door for more systems to drop into the area as we find ourselves under northwestern flow aloft. Another system will drop into the area over the weekend, bringing cooler temperatures to the area. Over the past 24 to 36 hours, this system has trended drier and drier as global ensembles converge on a more inland track. The way things currently sit, the most impactful weather phenomena associated with this system will be the 8 to 12 degree cool down from Friday to Sunday. Northwesterly flow aloft will persist through early next week, leaving the door open for additional low pressure systems to move through the area. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Winds will remain under 10 knots and follow typical daily directional trends through the forecast period. High clouds at or above 20kft will increase in coverage throughout the day. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Elevated northerly winds with peak gusts in the 20 to 30 knot range will persist through the day in the lower Colorado River Valley, decreasing in the evening. Otherwise, winds across most of the region remain light and follow typical daily directional patterns.
