At 1pm today, NOAA issued a Winter Storm Watch for the Sierra Nevada mountains of California from the northern border of Yosemite National Park to 14,495′ Mt. Whitney for Sunday and Monday. Snow is forecast all over the Sierras from their northern limit up near Susanville all the way to their southern end near Tehachapi pass in southern California.
Snow levels will start high, but 3-8″ of snow is expected down to 5,000-feet by Monday evening.
* ACCUMULATIONS...8 TO 16 INCHES ABOVE 7000 FEET. SNOW LEVELS WILL LOWER TO 5000 FEET BY MONDAY EVENING WHERE ACCUMULATIONS OF 3 TO 8 INCHES ARE POSSIBLE. - NOAA Hanford, CA
The Sierra Crest in the Lake Tahoe region is forecast to get around 12+” of snowfall according the the snowfall map below (3 images down). The Mount Rose area in north Lake Tahoe is forecast to get around a foot or more of new snow by Monday as well.
Up to 16″ of snow is forecast for Yosemite which most likely means that Sonora and Tioga Passes will get shut down by this storm as they are both right in the bulls-eye of this Winter Weather Advisory.
Snow levels will start around 7,000-feet on Sunday and drop to 5,000-feet by Monday morning.
“A Winter Storm Watch is in effect from Sunday evening through Monday morning between Kings Canyon and Yosemite NP above 7000 feet. Snow is expected to start falling Sunday evening above 9000 feet, gradually lowering to near 5000 feet by late Monday morning. Snow amounts up to over a foot can be expected, especially above 9000 feet in the Yosemite area. Up to 6 inches is possible over the higher elevations of the Tulare county mountains, and 1 to 2 inches above 6000 feet over the Tehachapi’s by Monday night.” – NOAA Hanford, CA
