Alta Sierra At Shirley Meadows snow report

434 FXUS65 KVEF 040748 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1248 AM PDT Sat Jul 4 2026 .KEY MESSAGES... * Dry conditions, breezy afternoons, and gradually warming temperatures continue through next week. && .DISCUSSION...Today through Friday. The persistent southwesterly flow pattern will continue through the weekend. A piece of energy from the remnants of Douglas will advect through the region Saturday night and Sunday. Despite weak moisture increases and modest forcing with this wave, think the dry forecast will hold as low levels are exceptionally dry. The HRRR does show some weak radar returns Saturday night and again Sunday afternoon, mainly in the Lower Colorado River Valley and Mohave County, but probabilities on ensembles for measurable rainfall is 10% or less. Will monitor the potential for showers though, especially Saturday night as virga may bring gusty winds during peak firework timing if something did develop. After this weak impulse exits, it will definitely remain dry through next week. Very dry conditions combined with afternoon southwest winds gusting to around 20 MPH means fires could easily start and spread- anyone participating in recreational activities for the holiday weekend including cooking with charcoal grills, participating in target practice, dragging chains off their vehicle, and/or using safe-and-sane fireworks are encouraged to take extra precautions, including carrying extra water to extinguish flames as necessary. An upper level ridge will re- position itself over the Southwest US next week which will bring warming temperatures, peaking Wednesday and/or Thursday. By Wednesday, widespread Moderate HeatRisk (Level 2 of 4) with isolated areas of Major HeatRisk (Level 3 of 4) are expected, which will last through the rest of the work week. Las Vegas, NV has a 50%-60% chance of officially hitting 110F for the first time this year Wednesday and Thursday. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Winds are expected to remain less than 10 knots through the night and into Saturday morning. Easterly winds are expected to redevelop by Saturday afternoon with sustained speeds of 7 to 9 knots, although occasional gusts to 15 knots are likely at times. Guidance has come into better agreement on a brief period of southeast winds (130-150 true) after 23Z before winds turn southwest by sunset. Temperatures exceeding 100F are expected between 21Z and 03Z. VFR conditions will prevail through the TAF period with FEW to SCT clouds with bases generally remaining AOA 20kft AGL. Brief reductions in visibility are possible after 04Z tomorrow evening due to fireworks along the Las Vegas Strip. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Winds are expected to follow typical diurnal wind patterns through the TAF period, with sustained speeds generally remain below 12 knots. The exception will be at KDAG, where westerly winds gusting to 20 knots are expected Saturday afternoon. VFR conditions will prevail with FEW to SCT high clouds with bases AOA 20kft AGL. Slantwise visibility reductions due to wildfire smoke are possible at times across the southern Great Basin and western Mojave Desert near KDAG. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Nickerson AVIATION...Planz For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
