The National Weather Service in Las Vegas is forecasting calm weather today, with conditions expected to change starting tomorrow. A weak weather system will bring a slight chance of showers to areas south of Interstate 40 on Tuesday, according to the NWS report. Temperatures are expected to be similar to or slightly warmer than yesterday, with increasing cloud cover throughout the day. However, by Wednesday and Thursday, a stronger system is predicted to bring gusty winds, widespread rain, and heavy mountain snow, along with a significant drop in temperatures.
Las Vegas residents can expect a mild Tuesday before weather conditions change. Light showers are forecast for areas south of I-40, but the chance of significant rainfall—exceeding 0.10 inches in a 24-hour period from Tuesday morning to Wednesday morning—is less than 20%. Snowfall is expected to be minimal, with only a light dusting, particularly in the Hualapai Mountains. However, winds will strengthen on Tuesday as an approaching trough moves in, with gusts potentially reaching up to 30 MPH in parts of Mohave County. Widespread wind gusts between 15 and 25 MPH are expected, with higher gusts up to 30 MPH possible in certain areas of Mohave County, as reported by the NWS.
Looking ahead to the latter half of the week, wind gusts exceeding 40 mph are likely across the region, particularly affecting San Bernardino, Inyo, Esmeralda, Nye, and Lincoln Counties from Wednesday morning through evening. These conditions are expected to continue into Thursday, with significant precipitation anticipated to impact both high elevations and lower areas, including the Las Vegas Valley. According to the NWS report, the most favorable window for widespread, substantial precipitation is expected from late Wednesday night through Thursday morning.
With significant weather activity on the way, the Las Vegas Valley and surrounding areas are expected to see temperatures drop 10 or more degrees below the seasonal average by Thursday into Friday. As the system moves east on Friday, wind intensity is expected to decrease considerably. The weekend is likely to bring some relief, with temperatures returning to near-normal levels, though forecasts indicate another trough could approach the region by early next week.
