The predicted temperatures for most of the Western United States,
(including Big Valley) are for higher than normal temperatures
throughout the winter.
The National Weather Service has a Climate Prediction Center which
produces long term weather outlooks for the United States and has made
available a number of maps showing the outlook for winter weather, one
of which is shown above. More maps are available from their web
site (CLICK

"More Outlooks: is on this page. The titles include letters such
as "DJF" which means December, January, February and so on.
"Even though the average temperature over the three-month winter
season is forecast to be above normal in much of the country, there
still will be bouts of winter weather with cold temperatures and frozen
precipitation," said retired Navy Vice Admiral Conrad C. Lautenbacher,
Jr., Ph.D., undersecretary of commerce for oceans and atmosphere and
NOAA administrator.
According to the
Climate prediction center, main factors which affect seasonal forecasts include El Nino and La Nina ocean temperatures, North Atlantic ocean temperatures and wet soils or snow cover throughout the year. The effects of El Nino this year are neutral and the map above which suggests above normal temperatures does not show much above. There are slightly elevated sea surface temperatures in the Western Pacific. There are no indications of weather being extremely warm or extremely cold. What we can say is the winter will probably not be very cold.El Nino is the name given to a 3 to 7 year cycle of warm water which
occurs in the eastern Pacific Ocean and has been observed to strongly
influence the climate.
The outlook of at least a not very cold winter is good news with
rapidly increasing heating fuel prices. The bad news is that we
can certainly look forward to colder winters in the next few years and
fuel prices will not go down. We should use this time to evaluate
our home heating systems and plan for the future.
