866 FNUS55 KVEF 121127 FWFVEF Fire Weather Planning Forecast for Southern Nevada Northwest Arizona and Southeast California National Weather Service Las Vegas NV 327 AM PST Fri Feb 12 2021 .DISCUSSION...Clouds will spread over much of the region this morning before clearing this afternoon as a weather system moves south through California. This system will bring gusty winds to the western deserts, along with slightly cooler temperatures and a chance of rain and mountain snow. The next system is hot on its heels, dropping over the area on Saturday. This second system is more potent and packs stronger winds which can be expected over much of the area on Saturday. It will also drop temperatures back closer to normal and increase chances of precipitation. Beyond the weekend, another system could make a glancing blow later Monday as it passes by the area. This could mean more wind and a small chance of precipitation. NOTE: Thunderstorms imply gusty and erratic winds.
