.SYNOPSIS...Strong high pressure continues to remain over the
region this week, maintaining unseasonably warm and dry
conditions across western Washington. Conditions will turn more
cooler and wetter over the weekend, with snow levels falling to
around 3000 to 4000 ft for the start of next week.
&&
.SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/...
High pressure continues over western Washington for another dry
and mild day. High temperatures this afternoon have been
generally in the mid to upper 50s in the interior. Areas along
the coast and in the Southwest Interior have seen high temps in
the mid to upper 60s. Conditions will be similar on Friday,
with high temps in the mid to upper 50 range across much of the
area.
Flow will turn southwesterly on Saturday with a system moving
into the region for a return of lowland rain and mountain snow.
Snow levels on Saturday will remain in the 6000 to 7000 fr
range and temps will cool in the low 50s.
&&
.LONG TERM /SUNDAY THROUGH THURSDAY/...Lowland rain and mountain
snow will continue on Sunday with snow levels lowering to 3000
to 3500 feet, with some accumulating snow expected in the
mountains and at the passes. This return of precipitation in the
south slopes of the Olympics will create rises on area rivers,
more notably the Skokomish River, keeping levels close to minor
flood stage late Sunday into Monday. Rain looks to taper by
Tuesday but an upper low will keep conditions cool and unsettled
heading towards midweek.
