FXUS65 KVEF 210944 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 244 AM PDT Sat Mar 21 2026 .KEY MESSAGES... * Anomalous early-season heat continues through the forecast period. && .DISCUSSION...Today through Friday. A ridge of high pressure persists over the Desert Southwest, resulting in continued anomalous early-season heat. A weak shortwave will ride along the upper-level ridge today, which will bring breezy southwest winds to the region as well as increased cloud cover mid- to-late afternoon. This cloud cover may arrive late enough to produce little in the way of relief to afternoon high temperatures for the Mojave Desert, but should help cool the southern Great Basin compared to the last few days. Additionally, this cloud cover will trap the heat overnight, likely resulting in numerous record warm morning lows. Afternoon temperatures cool by 3 to 5 degrees on Sunday and Monday... but will still remain around 30 degrees above seasonal normals. As the ridge rebounds mid-week, afternoon high temperatures increase once again to similar values as seen over the last few days. There is no substantial cooldown expected in at least the next 7 days. && .AVIATION...For Harry Reid...For the 12Z Forecast Package...Light winds will continue through the morning. Increasing southwest winds are expected this afternoon after 18Z. Gusts over 15KT are expected with a 30% chance for gusts over 20KT. Winds will diminish this evening as gusts end but wind speeds at 8-10KT persist until around 12Z Sunday. Light winds are then expected through Sunday morning. Clear skies will give way to increasing cloud at 20kft late this afternoon and tonight. For the rest of southern Nevada, northwest Arizona and southeast California...For the 12Z Forecast Package...Light winds are expected overnight. Breezy southwest winds will develop this afternoon across the Western Mojave Desert into southern Nevada and western Arizona. Widespread gusts of 15-25kt are expected in this area. Elsewhere, light winds under 10KT will continue through the afternoon. Gusts will dissipate after sunset and typical overnight wind patterns should return. Increasing SCT-BKN clouds at or above 15kft from west to east are expected through the TAF period. && .CLIMATE...Numerous climate locations have a forecast high temperature and/or forecast warm low temperature within 3 degrees of the daily record.
