656 FXUS65 KVEF 121124 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 424 AM PDT Sat Sep 12 2026 .KEY MESSAGES... * Breezy south-southwesterly wind gusts expected across the region Friday through the weekend. Continued dry conditions with these winds will lead to fire danger. * Temperatures cool through the weekend. && .DISCUSSION...through Thursday After hazardously hot conditions from a strong high pressure, the pattern finally changes into Saturday. A trough is deepening over the Pacific Northwest and push inland and south into Saturday. This will help shift the the high pressure eastward, but the space between these systems will narrow, leading to a stronger pressure gradient and increasing winds. Breezy winds build through Saturday morning and will peak that afternoon with widespread gusts above 30 mph possible and above 40 mph in higher terrain and within favored gaps and passes. This coupled with very dry conditions will increase fire weather concerns. Fire Red Flag Warning will go in effect at 11 AM for Esmeralda, Nye, and portions of Lincoln and Clark counties and will last into late Saturday night. Winds look to reduce for Sunday but remain breezy. Longer term models keep breezy winds peaking around 25 mph each afternoon into the first half of next week, but winds look to ease in the late week. As the high pressure pushes east and focuses over Texas, temperatures (both highs and lows) will begin to decrease through the weekend. High temps will fall back to around average (90s to low 100s) before the work week. Low temperatures will see some reduction, but will plateau in the early work week, and stay around 5 degrees above average. && .AVIATION...For Harry Reid...For the 12Z Forecast Package...A lull in gusty winds may occur early this morning before winds strengthen and shift to the southwest by mid morning, with sustained speeds over 10 knots and gusts between 20 and 25 knots.
