.SYNOPSIS...
Warm and dry conditions are expected today, followed by a brief
return to clouds and slightly cooler temperatures tomorrow. High
pressure rebuilds in time for the weekend, ushering in highs in
the upper 70s to 80s. Onshore flow resumes by early next week.
&&
.SHORT TERM /TODAY THROUGH SATURDAY/...
Pleasant temperatures in the low 70s are in store today with
mostly clear skies. A weak front will arrive in the area tonight
and bring increased cloud cover into Friday. No precipitation is
expected, but the the temperatures will be a couple of degrees
cooler, relative to today. That will be short lived as high
pressure amplifies more dramatically over the weekend and into
early next week. Widespread Minor HeatRisk will persist through
Saturday.

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Sunday will feature the warmest day of the forecast period, with
highs in the 80s for much of western Washington. Areas that will
likely be in the upper 80s include the Cascade foothills and
valleys as well as the southwest interior locations. Expect
highs in the 70s along the coast. This corresponds to Moderate
HeatRisk-which is prone to affecting those sensitive to the heat
and who may be without adequate cooling. Additionally, though it
will be warm outside, area bodies of water are not. Puget Sound
is generally around 50 degrees with area lakes and rivers not
much warmer. Please be cautious around colder water despite the
air temperatures. Relative humidity also looks quite low across
western Washington on Sunday. This poses an elevated risk of
fire danger primarily among dry grasses or dead and dry vegetation.
Warm temperatures continue into Monday as high pressure moves
overhead from the NE Pacific. Onshore flow returns on Tuesday,
bringing the temperatures back down by several degrees.
