075 FXUS65 KVEF 061131 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 431 AM PDT Sat Jun 6 2026 .KEY MESSAGES... * Expect increasing southwest winds and cooling temperatures this weekend and into next week. && .DISCUSSION...through Friday. A persistent trough will be the main driver of weather through the weekend and next week. First, temperatures will fall back to near normal values by Sunday, which means highs in the upper 90s to low 100s across much of the Mojave Desert. HeatRisk decreases from Moderate(Level 2 of 4) to Minor (Level 1 of 4) for most locations as a result. Highs should remain within a few degrees of normal throughout the week. The position of the trough will allow for an increase in southerly to southwesterly winds across much of the area. The strongest gusts should generally remain in the 30 to 40 mph range today, which will create rough waters and waves between 2 and 4 feet on Lake Mead and Lake Mohave. Gusty winds combined with dry conditions also raise elevated to critical fire weather concerns - see the FIRE WEATHER discussion below for more details. Winds may weaken a bit on Sunday, but are expected to strengthen again on Monday and Tuesday as the trough becomes reestablished. Additional periods of breezy winds are possible later in the week depending on the strength and position of the trough, but confidence in this setup is lower at this time. && .AVIATION...For Harry Reid...For the 12Z Forecast Package...Southerly-to-southweserly winds will continue through the TAF period. Winds will pick up after sunrise, and will continue to increase through the morning and into the afternoon with 20 to 30 knot wind gusts continuing late into the evening. Winds will begin to gradually decrease after sunset, with wind gusts dropping off early Sunday morning. VFR conditions will persist with no operationally significant cloud cover. Temperatures are expected to exceed 100 degrees from 19Z to 02Z, topping out around 102 degrees. For the rest of southern Nevada, northwest Arizona and southeast California...For the 12Z Forecast Package...Southerly-to- southwesterly winds will begin to increase across the region this morning and will continue to increase through the afternoon with 20 to 30 knots expected to continue into the evening hours. One exception to this will be the western Mojave Desert, KDAG, where winds will favor a more westerly direction with gusts in the 25 to 35 knot range. Another exception is the northern Owens Valley, KBIH, where winds will remain light, favoring typical diurnal directional trends until gusty westerly winds pick up later this afternoon. VFR conditions will persist through the TAF period with no operationally significant cloud cover expected. && .FIRE WEATHER...A combination of widespread southwesterly winds of 15 to 25 mph gusting between 30 and 40 mph, minimum RH values between 5 and 15 percent, and dry fuels bring critical fire weather conditions to much of the area today. Red Flag Warnings cover all of southern Nevada and northwestern Arizona except for Nevada Zone 460. This warning continues into Sunday for northwestern Arizona, where gusty winds will persist as the trough moves east. Another round of gusty winds and dry conditions is expected on Monday and Tuesday as the trough strengthens again, and a Fire Weather Watch has been issued for all of northwestern Arizona and most of southern Nevada for this time as well. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION/FIRE WEATHER...Meltzer AVIATION...Stessman For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
