Don't credit global warming. And don't call it karma. Sometimes, weather patterns just lock in place, says KPLU weather expert Cliff Mass.
Today, the pattern is perfection. Sunny, clear skies, with temperatures in the upper 60s, occasionally breaking 70, says Mass, a professor of Atmospheric Sciences at the University of Washington. And seven days in a row of that, stretching through next Thursday. It could change at the end of next week, but maybe not, he says.
