NWS Las Vegas, NV wrote its last area forecast discussion before the first event at Aug 24, 11:42 AM PST, 53 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Las Vegas NV 1242 PM PDT Sun Aug 24 2025 .KEY MESSAGES... * Showers and thunderstorms capable of producing gusty outflow winds and flash flooding will continue into the evening, with the highest risk for thunderstorms and impacts in Inyo County through the Southern Great Basin. * Another round of showers and thunderstorms is expected on Monday, with similar conditions to today but potentially higher thunderstorm areal-coverage. * Chances for showers and thunderstorms will continue through the middle of the week, with Tuesday potentially being the peak in thunderstorm coverage and impacts. It will then dry out as we head into the weekend. && .DISCUSSION...Through Saturday With a moist atmosphere and ample sunshine to allow for destabilization- scattered thunderstorms developed across the region late this morning. Development is expected to continue through the afternoon with convection favoring the terrain at first. Later this afternoon, outflow boundaries may allow for additional thunderstorm development away from terrain. The highest coverage of thunderstorms should be in the Sierra into northern Inyo and Esmeralda as upslope flow and a weak piece of energy shifts through the area. With at least 1.00in PWATs across the region- heavy rain and flash flooding is possible, especially with nay storms that anchor and train over terrain. DCAPE will remain over 1500 J/Kg in most location, and the 12Z Las Vegas sounding shows dry low levels as well as some dry air in the mid levels, so sudden gusty winds over 40 MPH will also be possible with any storms today. HREF is highlighting probabilities for sudden gusty winds in the lower Colorado River Valley through the evening, boaters should be prepared for changing weather conditions and gusty winds. After a lull in convection tonight, addition showers and thunderstorms are expected to develop on Monday. The heavy rain and flash flood threat may be lower on Monday compared to today as a bit of dry air moves into the area, whoever with a weak shortwave and cooler temperatures aloft moving in as well there will still be some threat. Thus- conditions on Monday are expected to be fairly similar to today as HiRes models though coverage of afternoon thunderstorms may be more widespread than today. Chances for showers and thunderstorms will continue into the middle of the week as our anomalous monsoonal moisture sticks around. A weak shortwave trough will approach the coast of California on Tuesday, providing additional lift to help fuel showers and thunderstorms on Tuesday and Wednesday. Ensemble members continue to highlight Tuesday as the day with the best chances for widespread convection with showers and thunderstorm activity lingering into Wednesday and potentially Thursday for portions of the area. Hazards with these mid-week storms will be similar to today and tomorrow's convective hazards. Eventually the dry southwesterly flow aloft resulting from this shortwave will scour moisture from the area with things drying out as we head into the weekend. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Showers and thunderstorms will develop around the terminals this afternoon, favoring the mountains to the south and west. Low chance for direct thunderstorms over the terminals today, however nearby convection could push one or more outflow boundaries toward the terminal, resulting in sudden erratic wind shifts. Storms will weaken and dissipate by sunset. Monday is expected to be similar to today but with higher thunderstorm coverage as well and a higher chance for thunderstorms over the terminals. Other than sudden gusty winds- any storms today and Monday could result in heavy rain, lightning, and CIGs to 10kft. Temperatures are forecast to be above 100F from 19Z to 04Z, but thunderstorms at or near the terminal could shorten that time window. For the rest of southern Nevada, northwest Arizona and southeast California...For the 18Z Forecast Package...Scattered showers and thunderstorms are expected areawide today, with the greatest threat and highest thunderstorm coverage expected in the Sierra and northern Inyo County. Storms today could produce sudden gusty erratic winds, CIGs to 8kft-10kft, lightning, and heavy rain. Convection will wane tonight, but addition showers and thunderstorms are expected across region on Monday. Outside of thunderstorms, winds should follow typical patterns with speeds to around 10KT with prevailing VFR conditions. Looking ahead- The threat of afternoon showers and thunderstorms will continue across the region each day through at least Wednesday, with the most coverage expected on Tuesday. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && DISCUSSION/AVIATION...Nickerson For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
