Maybe they're thinking of Denver? Doesn't sound like the PNW I know. Although occasionally you do get some nice days in February. Not 70F nice, though.
I hesitate to pick on a post that was probably just a typo or remembering slightly wrong, but I was wondering so I looked it up: the record high for Seattle in January is 67F recorded in 1931. And the record low is zero...Fahrenheit. Yoiks, I'd have to consider moving again if it hit zero. :-)
