Friday and Saturday are shaping up to be the hottest days so far this year across much of Northern California. Just two days later, valley and coastal rain and Sierra Nevada snow could be back in the forecast. It’s part of an unsettled spring weather pattern that continues across the West Coast. … Rainfall totals will depend on the trajectory of the storm. If it moves inland quickly, little to no precipitation will fall in the Bay Area. If the storm remains over the ocean, it will pick up more moisture and could deposit a tenth to a half-inch of rain in parts of the Bay Area. This wet scenario may also yield a half-foot of snow in the northern Sierra.
