350 FXUS65 KVEF 142313 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 415 PM PDT Mon Sep 14 2026 .KEY MESSAGES... * Breezy south-southwesterly wind gusts will continue through the week with dry conditions and near-normal temperatures. && .DISCUSSION...Persistent troughing across the Western US will keep the region in a generally dry and breezy pattern through much of the upcoming week. In the near term, a trough will eject into the Northern Plains today before additional troughing drops south along the Pacific Northwest Coast by midweek. This will keep the Mojave Desert and southern Great Basin region in a southwesterly flow aloft, favoring breezy conditions in the afternoons and any lingering monsoonal moisture focused more across central and eastern Arizona. A few isolated thunderstorms may develop across eastern Mohave County through midweek, but coverage is expected to be quite limited. Otherwise, thanks to the pattern at hand, temperatures will remain near seasonal normals through the period. The flow pattern will trend more zonal by the weekend allowing for the gusty winds to ease while temperatures remain near normal. && .AVIATION...For Harry Reid...For the 00Z Forecast Package... Overall normal daily summertime wind pattern expected through the TAF period with breezy afternoon and evenings and lighter winds at night. SW winds 10-15kt with gusts 20-25kt continue through around sunset this evening, then gusts drop off for the overnight hours while S-SW winds diminish to 08-10kt. Brief period of SE-S winds expected around 16z before a quick wind shift to S-SW 10-15kt with isolated gusts over 25kt at times during the afternoon Tuesday. by VFR conditions prevail, with temperatures briefly reaching a high of 100 degrees around 23Z-00Z. For the rest of southern Nevada, northwest Arizona and southeast California...For the 00Z Forecast Package...Overall daily wind patterns expected at most sites through the TAF period, with a few exceptions. For the rest of today, S-SW winds with gusts 20-25kt continue through sunset then diminish some for the overnight hours. Guidance shows the potential for elevated winds near 10-12kt overnight with isolated higher gusts at KIFP and KEED. KBIH is also an exception as winds have been light and VRB much of the day. Expect a brief period of SE-S winds through sunset, then a shift toward light NW flow tonight. Higher confidence does exist in stronger SE-S winds 10-15kt with gusts to 25kt at KBIH during the afternoon and evening Tuesday. KDAG remains light and VRB out of the NE, but expect the daily WSW push to occur 00z-02z and persist through 09-10z. VFR conditions will prevail, with isolated thunderstorms expected over portions of northwestern Arizona this afternoon that are unlikely to cause any impacts at area terminals. && .SPOTTER INFORMATION STATEMENT...Spotters are encouraged to report any significant weather or impacts according to standard operating procedures. && $$ DISCUSSION...Outler AVIATION...Moore For more forecast information...see us on our webpage: https://weather.gov/lasvegas or follow us on Facebook and Twitter
