Post-Thanksgiving Sierra Winter Weather Advisory

The National Weather Service has issued a Winter Weather Advisory for the Sierra Nevada above 4000 feet, which is in effect from 4 pm Saturday to Noon Sunday.

A Pacific frontal system moving into Northern California will bring light precipitation to the northern part of the state today. This precipitation is expected to remain north of Interstate 80 and the higher elevation snowfall is not expected to be especially heavy.

A more significant wave of precipitation will move through Northern California on Saturday. This will bring periods of heavier snow to the Sierra Nevada first north of Interstate 80 in the morning, then south in the afternoon. Moderately high snow levels are expected and this will likely impact holiday travel over the Sierra through at least the middle of the day on Sunday. In addition to the snow, breezy to gusty winds may cause white out conditions at times.

The main impacts will be slippery roads and possible chain controls.

Total snow accumulations will range from eight inches to fifteen inches.

A Winter Weather Advisory means that periods of snow will cause primarily travel difficulties. Be prepared for snow covered roads and limited visibilities and use caution while driving.
