o The EPA's Office of Water encourages all citizens to learn about their water resources and supports volunteer monitoring because of its many benefits. Volunteer monitors build awareness of pollution problems, become trained in pollution prevention, help clean up problem sites, provide data for waters that may otherwise be unassessed, and increase the amount of water quality information available to decision makers at all levels of government. Among the uses of volunteer data are delineating and characterizing watersheds, screening for water quality problems, and measuring baseline conditions and trends.

Weather models forecast dry weather through Thanksgiving, but disagree on what to do with the left-overs. The GFS model shows an upper level trough and associated cold front moving into Northern California on Friday, then stalling, possibly entraining subtropical moisture, and eventually dissipating before reaching Southern California. The GFS forecasts 48 hour precipitation totals of up to 4 inches along the frontal boundary. Other models project different solutions. NCEP Ensemble members show a large variance in the 500mb pattern over the eastern Pacific at 120 hours, emphasizing the degree of uncertainty.
Forecasts for central California and the Southern Sierra appear to be leaving in a chance of a little rain or snow in the late Friday to Saturday timeframe. Current model forecasts and guidance suggest a low probability of significant precipitation for the area this weekend, but we'll have to see how the Pacific system evolves. According to the current GFS forecast, the system spins off the coast until early next week, then moves into central California.
The long lead seasonal precipitation forecast issued November 20, 2003 for Dec-Jab-Feb indicates a precipitation probability anomaly of 40% below normal over a large area of Southern and Central California. In the context of this forecast, this equates to a 73.3% probability of below normal, 23.3% probability of normal, and only a 3.3% probability of above normal precipitation in the area depicted. However note that this forecast has marginal skill in forecasting precipitation. According to the CPC:
“For all models precipitation forecasts are generally less skillful than temperature -- with marginal skill for all tools even in their best seasons and locations under normal circumstances.”
So far this rainy season has appeared to follow a more or less normal course with average to above average precipitation over the last 28 days in most of California. The current 6 to 10 day, and 8 to 14 day, outlooks forecast above average precipitation for Southern California.

Northern California is forecast to be the focus of the second round of precipitation to affect the state this rainy season. The HPC 3-day precipitation forecast suggests a large part of Northern California should see rainfall totals in excess of 1.5 inches with over 2.5 inches in some areas.
Forecast precipitation totals fall off dramatically to the south. The ETA 60 hour precipitation forecast from this morning shows a bulls eye of over 3 inches in Northern California, around 0.75 to 1.5 inches in the Central Sierra, and anywhere from 0.1 to 0.75 inches in the Southern Sierra.
It is possible that the Sierra could see more snow than currently forecast. This meso ETA forecast sounding for Porterville for Sunday morning shows a relatively moist, 20 to 30 knot west-southwesterly flow in the middle levels. This could result in some orographically induced snow, and if the air mass is wetter than forecast, more snow would result. Another wrinkle is a jet max that is forecast to be favorably positioned Sunday morning and could enhance lift over the Central Sierra. We'll see!
(11/10/2003 7:00 A.M. Recorded storm totals (inches liquid equivalent): Upper Tyndall Creek 1.1, Pascoes 1.4, Tunnel Guard Station 1.2, Wet Meadows 1.5, Johnsondale 0.7, Kernville 0.6)
According to NOAA scientist Dr. Klaus Wolter the Multivariate ENSO Index value of 0.56 for Sep/Oct "represents the highest value since Feb/Mar 2003, ranking at 37 out of 54, just inside the upper tercile criterion for El Niño events (ranks 37-54). Although this is a far cry from being safely in El Niño territory, a transition back to La Niña appears very unlikely for the next several months."
The current 6 to 10 day NWS forecast for Southern California is for normal temperatures and normal precipitation.
