Off to stock up on supplies, but wanted to post this first:

Friday will be a transitional day with increasing clouds, warmer overnight lows and southerly winds as an intense storm develops off the Northern California coastline.

The models are indicating that a 975 millibar low-pressure system will be centered about 100 miles west of Cape Mendocino on Friday with the associated cold front moving through the Central Coast on Saturday with moderate gale-force to strong gale-force (32 to 46 mph) southerly winds along the coastline and moderate to heavy rain. Rain showers are expected on Saturday night into Sunday afternoon. Total rainfall amounts are forecast to range between 1.00 and 1.75 inches. This storm will also produce snow across the Sierra Nevada above 5,000 feet with more than a foot of snow possible over the higher terrain.

Partly cloudy and dry weather is expected on Monday, before another low-pressure system brings additional wet and unsettled weather next Tuesday, Wednesday and Thursday.
