Temperatures in the valley were slightly cooler during the beginning part of the week due to the cloud cover; reaching from the mid 70s to near 80 degrees in the Sacramento Valley.
The Southern California coast and mountains experienced warmer temperatures due to dryer weather and fewer clouds; with temperatures ranging from upper 70s to near 100 degrees.
The Central Coast, including the San Francisco Bay area, remained in the 60s to around 70 degrees throughout the week. The overall weather pattern began to change to a more fall-like pattern on Thursday.

The higher elevations of the northern Sierra Nevada received moderate snowfall amounts as well. On Saturday, gusty winds across the valley and surrounding mountains, and minor flash flooding cases over the wildfire burn scars in the foothills and mountains were confirmed during the peak of the weather event.
