A strong high pressure system with very little movement lingered over the Northern California region, bringing unseasonably dry and warm weather across the state, according to the National Agricultural Statistics Service (NASS) in Sacramento, Calif.

Temperatures reached from the upper 70s to mid 80s in the Sacramento Valley, reaching to around 90 degrees in the northern cities by the end of the work week. In the Bay Area and the Central Coast, very little fog was reported and the temperature reached the 80s throughout the week.

The southern coasts and mountains experienced warmer temperatures of upper 70s to mid 90s. In the northern mountains, the temperature topped in the mid 70s during this same period. Gusty east to northeast winds over the west slopes of the northern Sierra Nevada kept temperatures slightly warmer than normal overnight. These winds gust to near 35 mph through the canyons.

The high pressure played a key role for the large scale weather over the whole state during this period. A cooling trend with increasing periods of rain is now expected as the fall season becomes more predominant.
