Weather Summary
An atmospheric river will take aim for California this weekend with heavy precipitation, high snow levels and soils that are already saturated from recent storms. Moderate precipitation starts Saturday (7th), but the brunt of the storm will be Sunday and Monday; the majority of the precipitation will fall as rain in the mountains as snow levels rise above 8000 feet. This is going to be some of the more significant flooding we've seen in the past decade...areas may flood that haven't seen impacts for several years. Use the break in the weather late Thursday and Friday to prepare. Keep in mind that flooding will take several days to recede in some areas after the rain stops.
