Radar reflectivity continues to show light-to-moderate shower activity spreading inland over Humboldt, Del Norte, Siskiyou, and Trinity counties in northern California. These showers will continue to spread inland and dissipate over the next several hours. After a period of dry conditions through much of the week, the storm track is forecast to shift back towards CA, increasing the potential for heavier precipitation through the weekend. Models continue to show large spread in terms of timing and intensity, though the EC suite continues to be more bullish than the GFS. Little to no changes were made to the afternoon forecast, placing the heaviest precipitation accumulations of 4+ inches over the Smith Basin. Other high elevation locations, such as the northern Sierra, Mt. Shasta and Cape Mendocino are forecast to receive 3+ inches. Expect forecast accumulations to be adjusted as new model guidance is updated over the coming days. Please Note: This product may NOT be routinely updated.
