Excessive Rainfall Possible Friday across Northern California
As an upper level disturbance and associated Pacific low, that had brought snowfall to the Sierra Nevadas on Thursday, finally makes its way onshore Friday evening, ample moisture will spread across the region throughout the day. With the low providing lift, showers will increase in coverage and intensity. An additional 1-3 inches with isolated higher amounts in excess of 4 inches are expected, on top of the rainfall on Thursday.  This will pose a risk for localized flooding and runoff.
