... Hot Summer weather is expected across western Washington this
Temperatures are forecast to climb well above normal this
weekend. Sunday will likely be the hottest day of the year so
Highs on Saturday are forecast to climb into the upper 80s to
lower 90 across western Washington. The warmest locations will be
a few miles east of Puget Sound, the southwest interior and along
the coast from about Forks to Hoquiam.
Sunday is expected to be hot and will likely break some daily
high temperature records over portions of the area. Highs on
Sunday will be in the 80s to mid 90s. The record high for sea-tac
Airport on Sunday is 88 set in 2006 and will likely be surpassed.
The hottest temperatures will be in the interior lowlands from
Seattle southward along the I-5 corridor. It will be 2-3 degrees
cooler on Sunday along the coast than on Saturday.
Temperatures will begin to moderate Monday. The onset of onshore
flow is somewhat uncertain and some interior lowlands east of
Puget Sound near the foothills could still reach the mid to upper
80s. Other interior Metro areas from Tacoma north to Seattle and
Everett could potentially reach the lower 80s.
If you are planning to enjoy our rivers, lakes, and waterways
this weekend, please wear a life jacket while on a boat. Also, be
aware that rivers are running swift and water temperatures are
still rather cold, ranging from the 40s near the mountains to
around 60 degrees near Puget Sound. Hypothermia and drowning due
to cold water shock can occur with these water temperatures.
