In fact, there is around
a 70-90% chance that temperatures exceed 90 degrees across parts of
the Portland/Vancouver metro. If PDX reaches 90 degrees on Sunday
(May 3rd), it would be the second earliest 90 degree temp of the
season at the airport (the earliest recorded 90F at KPDX was April
30, 1998).
