Scorching heat is expected to continue into at least the first half of the weekend across the Pacific Northwest. Temperatures early Friday afternoon were well into the 90s in places around Seattle, with the mercury approaching or exceeding 100 degrees in cities such as Portland, Eugene, Salem, Medford and Redding. The only relief is places immediately along the coast, where the cooler ocean waters are keeping seaside towns locked in the 50s and 60s. But you only have to go inland about a dozen miles or so to see temperatures spike up into the 90s.
As of 2 p.m. PDT Friday, Seattle and Portland had already surpassed their daily record highs, which were 89 and 97 respectively. Salem, Oregon has also broken the record high of 99 for Friday, while Eugene was just a couple degrees shy of their record high of 101. (UPDATE: Eugene did set a record, topping out at 104 degrees Friday afternoon)
