What's Next for the Pacific Northwest?
Neutral ENSO conditions exist in the equatorical Pacific Ocean, according to the Climate Prediction Center (CPC). During the last 4 weeks, sea-surface temperatures (SSTs) throughout the western and central equatorial Pacific Ocean have remained near-normal while those in the eastern equatorial Pacific were between 0.5 and 2 degrees Celsius below normal. A majority of the models are predicting neutral conditions to persist through summer 2013.
What does this mean for Washington in the coming months?
The CPC three-class June-July-August (JJA) temperature outlook has equal chances of below, equal to, or above normal temperatures for a majority of the state. Most of the US is expected to have warmer than normal temperatures, however, and this extends into southeast WA as well. For precipitation, the JJA outlook has increased chances of below normal precipitation statewide with higher chances of drier conditions in eastern WA.
The late summer (July-August-September; JAS) CPC three-class outlook is very similar: there are increased chances of above normal temperatures in southeast WA and increased chances of below normal precipitation statewide.
