Sunday will see a high of 90 at Seattle-Tacoma International Airport, the Seattle branch of the National Weather Service predicts. The record high for Aug. 24 is 88 degrees, set in 1982.

The extreme heat warning began on Friday after a high-pressure system moved into the region, and is in effect through 5 p.m. Tuesday.
