NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Jul 28, 9:31 PM PST, 2 hours 29 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1031 PM PDT Mon Jul 28 2025 .KEY MESSAGES... * Monsoonal moisture increases across Arizona mid-to-late week, with best chances of precipitation across Mohave County. && .DISCUSSION...Today through Monday. A ridge of high pressure over the southern CONUS will continue to retrograde westward through the week. Monsoonal moisture will swing clockwise around the high before surging up the Colorado River Valley mid-to-late week. Of note, with each forecast run, the amount of moisture and the north / westward progression of this moisture has diminished. Across southern Nevada, ECMWF and GFS ensemble runs show 0.25 to 0.40 inches of PWAT today through Wednesday, peaking on Thursday and Friday to 0.50 to 0.75 inches before rapidly retreating. Far southern zones of our forecast area including Lake Havasu City, Needles, and Laughlin-Bullhead City will experience PWATs peaking between 0.75 and 1.00 inches Thursday and Friday. PoPs on Tuesday are now negligible, with slight (5-20%) chances creeping into Mohave County Wednesday... spreading across the eastern half of the county Thursday and Friday... becoming negligible once again on Saturday. Due to the dry low-levels, any rain that falls this week will remain less than 0.05", making strong, gusty winds the primary hazard with storm formation. Still considering the possibility for a strong storm system over Arizona kicking off an outflow toward our forecast area, which, depending on the depth of the moisture in the outflow, could result in an overachieving rainfall forecast. This will be unfortunately hard to predict more than 24 hours out, but is becoming decreasingly likely. Additionally, a shortwave moving through the southwest flow aloft will tap into modest moisture in the southwestern Great Basin on Wednesday, bringing slight PoPs to northern Esmeralda and northern Inyo counties. The remainder of the forecast area will remain mostly sunny with at-or-above normal temperatures through the weekend, with HeatRisk peaking at "Moderate" in desert valleys. && .AVIATION...For Harry Reid...For the 06Z Forecast Package...Southwesterly winds of less than 10 knots become variable in the early morning. Winds start to favor an easterly to southeasterly direction in the late morning, which will give way to breezy southwesterly winds in the mid afternoon. Expect temperatures of 100 degrees or higher between 20Z and 03Z. For the rest of southern Nevada, northwest Arizona and southeast California...For the 06Z Forecast Package...Winds generally follow typical daily patterns through the TAF period. Southwest winds pick up in the afternoon in the Las Vegas Valley and Colorado River Valley with occasional gusts between 15 and 20 kts. Expect a more southeasterly direction at KBIH. Gusty westerly winds at KDAG will decrease early Tuesday morning and return in the evening. Skies will be mostly clear. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION...Soulat AVIATION...Meltzer For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
