Locally heavy rainfall with heavy snow above 6000 feet is possible Wednesday along the coastal areas of California. Heavy snow above 4000 feet is possible across the Sierra Nevada and the Northern California Coastal Range. Areas of significant high elevation snow will be possible across the Four Corners region.
Another cold front will move into Southern California this afternoon resulting in the continued threat for widespread and locally heavy rain along with high elevation snowfall. An additional 1-3 inches of rain is possible west of the mountains with 3-5 inches possible in the mountains. This will result in the continued threat for localized flooding/flash flooding. Mud slides will also remain a concern. Elevations above 5000 feet will experience the precipitation in the form of snow. An additional 1-2 feet of total snow accumulation is possible above 5500 feet in elevation through early Thursday.
Continued significant accumulating snow is expected across the Sierra Nevada and the Northern California Coastal Range with snow levels falling to around 4000 feet in the Sierra and 3000 feet over the northern coastal range.
An area of low pressure will advance eastward through the Four Corners region resulting in several inches of snow in the favored high elevation locations across Arizona, Utah, southwestern Colorado, and Northern New Mexico.
