NOAA is forecasting the first snowfall of the season for California’s Sierra Nevada. The weather will roll through on Tuesday, dropping as much as 4-8″ of snow above 8,000 feet.
NOAA Forecast Discussion:
A few changes were made to the long term with cool and showery weather early, then drying out late in the week. The models are still a bit divergent for the ejection of the low Wednesday with the EC slower and wetter. Trended pops upward for Wednesday and cooled temperatures also. It looks more showery so even if the EC is right it won`t be a washout. Snow levels still look to remain closer to 10,000 feet.
Thursday is where the biggest changes lie as the models and ensembles are in better agreement in bringing a slider type system
through. The GFS is now a bit drier and farther east with the EC being colder and wetter. The wetter solution would not surprise me if the EC track is correct as unlike most sliders this will have moisture to work with ahead of the front too. At this point, kept snow levels 9000 feet or so, but they could drop to 7000-8000 feet depending on how far west the system tracks.” – NOAA Reno, NV
