The juicy plume of remnant typhoon moisture (a common ingredient for October extreme precipitation events in the Sierra, recall back in 2009) will supply ample water vapor leading to 3-6 inches of liquid over the weekend. A few days ago, the Pacific looked like this:

This weekend's events will be absolutely superb for several reasons. 1) as the ground becomes saturated, it will be set to freeze and cause minimal damage to vegetation after a very dry and rather hot summer, 2) the trails will be in tip top shape once they dry out after a few days (don't ride too soon! nobody likes rutted berms) and 3) streams and lakes will receive a nice boost in flow/level.
