815 FXUS65 KVEF 031910 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1210 PM PDT Wed Jun 3 2026 .KEY MESSAGES... * Quiet weather with above-normal temperatures continue through the work week. * A trough approaches this weekend, producing some modest increase in winds and cooling temperatures slightly. && .DISCUSSION...through Tuesday. We`ll see a quasi-zonal flow pattern through the end of the work week, allowing temperatures to continue their gradual warming trend. Warmest days will be Thursday and Friday, with highs largely ranging from 95-110 degrees across the region. This yields widespread moderate HeatRisk, with a pocket of major HeatRisk in the Las Vegas Valley thanks to warm overnight lows caused by the urban heat island effect. Those sensitive to the heat, planning to be outdoors for long periods of time, or without adequate cooling or water should take precautions to protect from heat-related impacts. The pattern begins to change this weekend and into next week as a moves into the western US and lingers. Since the bulk of the forcing stays to our north and there is meager moisture to work with, precipitation chances with this system are confined to the Great Basin. The most noticeable changes with this trough will be the cooler temperatures and increased southwest winds. Highs are forecast to drop 6-12 degrees from Friday to Sunday, bringing us back to seasonable values. On the wind side, looking at peak gusts on Saturday and Sunday generally 25-45 mph. Strongest winds will be in our typical southwesterly wind belt (basically ~75-100 miles on either side of the I-15 corridor), where there is a 50-80% chance of minor wind impacts. Perhaps the greatest concern will be the increased fire danger with low RH values, gusty conditions, and fuels that are approaching critical. Winds subside but remain breezy next week as the trough lingers. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...A period of southeast winds with intermittent gusts to around 15 knots is expected early this afternoon, swinging around to the south by 00Z. Occasional gusts will persist through sunset. Winds will decrease overnight, becoming light and variable by sunrise. Similar wind patterns are expected on Thursday, with occasional gusts out of the southeast developing during the afternoon. Temperatures this afternoon will top out near 103F, with readings exceeding 100F between 20Z and 03Z. A high around 106F is expected Thursday afternoon. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Across the region, winds will generally remain between 5 and 10 knots and follow typical daily directional patterns through Thursday. The exceptions will be in the Colorado River Valley, where breezy south-southwest winds will pick up this afternoon, and across the western Mojave Desert, where breezy westerly winds will increase around 00Z today. Other areas will see occasional gusts of 10 to 20 knots during peak afternoon heating. VFR conditions will prevail through Thursday with no operationally significant cloud cover expected. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Woods AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
