Weather Washington Cascades: Extended Outlook

Issued May 23, 2018

Many of the extended models bring the Washington Cascades above normal temperatures and below normal precipitation. This will be the pattern through June 5. However, the European model (see below) shows a trough of low pressure at times and a ridge of high pressure at times. So this will bring more normal temperatures and precipitation.
