An upper level low with embedded disturbances brought isolated showers and thunderstorms to the region. Model data indicated that any available moisture would be

above 700 millibars so rainfall with any thunderstorms would be limited. These conditions, combined with seasonably dry fuels and moderate to poor humidity recoveries, led to fire weather concerns for northern California.
