The 90 Day Climate Forecast

The PNW should expect average temperatures with below average precipitation through the end of January.

El Nino Watch:
EL Nino/La Nina is currently in a neutral state trending towards a weak El Nino. However, the trend toward El Nino slowed during the month of October which supports the PNW long rang prediction of a normal start to winter in both precipitation and temperature. The most recent models are now split on whether El Nino conditions will emerge at all this winter. This also supports the long range forecast for the PNW to have a near normal winter.

Normal is good.
