177 FXUS65 KVEF 181720 AFDVEF Area Forecast Discussion National Weather Service Las Vegas NV 1020 AM PDT Sat Oct 18 2025 .KEY MESSAGES... * Dry conditions and a slow warming trend will yield a return to near normal temperatures through early next week. * A weak midweek system will bring slightly cooler temperatures, increasing winds and clouds, and a chance of showers to portions of the region. && .DISCUSSION... The quiescent pattern continues across the region as ridging continues to build in the wake of a potent trough currently translating across the southern Rockies into the Plains. Increasing heights will allow for a continuation of the slow, gradual warming trend, with highs near seasonal norms expected by Sunday and Monday. Given a lack of ample moisture as well as any appreciable forcing mechanisms, the forecast also remains dry, maintaining the fall-like feel into next week. Ensemble guidance and cluster analyses continue to be in very good agreement regarding the evolution of the upper pattern, with a low pressure system currently west of Baja progged to translate northeastward across southern California, weakening substantially as it then progresses eastward across the Four Corners. Given these trends and the expected track of the system, impacts locally will largely be limited to an increase in moisture and cloud cover, with the blended solution maintaining low (10-20%) chances for precipitation over northwestern Arizona on Wednesday. A subtle uptick in winds is also expected, but currently, winds look to remain below Advisory criteria. Behind this system, a period of ridging is expected to redevelop, yielding more dry, seasonable conditions for the end of the workweek. && .AVIATION...For Harry Reid...For the 18Z Forecast Package...Light easterly winds expected today, then returning to the southwest after sunset.
