PORTLAND — After a chilly, wet spring, hot weather is arriving this week in Oregon. The National Weather Service has issued a heat advisory for northwest Oregon and southwest Washington from Wednesday morning through this evening. Temperatures in the mid to upper 90s are forecast. Forecasters say the elderly and those without air conditioning are most vulnerable.

Steve Pierce is vice president of the Oregon chapter of the American Meteorological Society. As he puts it, "The oven has been turned on and it won't shut off until the weekend."

High temperatures Tuesday hit 84 in Portland and 87 in Eugene and Corvallis. The Oregon coast was sizzling too, with highs of 80 at Astoria, 88 at Tillamook and 88 at Florence. In southern Oregon, Medford hit 96. Vancouver, Wash., had a high of 86.
