Children splashed about as adults dipped their toes in Portland fountains seeking relief from a heat wave that's baking a region famous for cool weather.

In normally temperate Oregon and Washington, warm days mean drawing shades and running fans. But a searing high-pressure system was making Portland and Seattle sizzle and leading residents to hunt for air conditioning.

Portland hit 100 degrees (37.7 Celsius) on Wednesday and Seattle 90 (32.2 Celsisus).

The National Weather Service issued an excessive heat warning for western Washington and Oregon and said the highs in Seattle on Thursday could hit 95 (35 Celsius) while Portland could reach 105 (40.5 Celsius).
