Reno – NV, US, National Weather Service – December 30. 2020 – Extensive Period of Stormy Weather Anticipated to Start 2021. A notable change to a more active weather pattern is forecast for the Sierra and western Nevada with multiple periods of strong winds, heavy mountain snow, along with valley rain and snow. This will likely cause significant travel impacts in the Sierra next week. Chances for valley snow (including down here in Reno/Carson) will be increasing by midweek.
Fast-moving storm tonight through Thursday: A round of gusty winds to most areas along with light snow. Accumulations mainly low-end with a few inches in the Sierra and a dusting to less than half an inch for western Nevada valleys. Slippery travel and commute issues are expected Thursday morning. Active storm track for next week: A much wetter and windier pattern is expected to begin late in the weekend and last through much of next week as a series of Pacific storms with adequate moisture affects the Sierra and western Nevada.
Showery precipitation is expected to begin Saturday through the weekend, with the best chances for strong storms with significant precipitation and wind looking to be Sunday night into Monday and again Tuesday into Thursday. The latter storm is trending colder, which means increased chances for snow in western Nevada valleys. Abundance of impacts next week: Periods of heavy snow in the Sierra with significant travel disruptions for passes along with avalanche concerns. Rain or snow (or both) for mountain valleys and western Nevada valleys. Strong winds are possible, which may result in impacts for high profile vehicles and aviation, and possible tree and fence damage near wind prone areas.
Keep a close eye on the forecast, be sure to allow extra time, and check road conditions with NDOT and Caltrans before you depart.
