Short Term: Persistent Heat Likely Through Early September
Dangerous heat is building across the Pacific Northwest this week and into the weekend. Warmer than normal temperatures are also expected to persist over the next couple of weeks, as illustrated in the Climate Prediction Center 6-10 Day Temperature Outlook below.
Early August Climate Outlook
ENSO-neutral conditions are likely to continue through October according to the Climate Prediction Center (CPC). Neutral conditions make it more difficult to predict upcoming fall conditions. There are roughly equal chances of either La Niña or neutral ENSO conditions for the upcoming winter, with much lower chances of El Niño conditions.
