...the first substantial rain in quite some time expected over
southwest washington and northwest oregon late this week and
especially this weekend...
...windy conditions expected over southwest washington and
northwest oregon late friday night and saturday morning...
a big change in the weather is expected over southwest washington
and northwest oregon as the first substantial rain is expected
over the area late this week and this weekend.
this could be the most rain most areas in southwest washington
and northwest oregon have seen since march. rainfall accumulations
through the weekend will probably range from 1 to 2 inches along
the coast and over the coastal mountains and in the south
washington cascades...with 0.75 to 1.5 inches in the oregon
cascades and 0.5 inches or higher in the valleys.
the rain will be produced by the low pressure system currently
located off the coast as it moves onshore and inland into the
pacific northwest later this week and this weekend. this system
will be picking up substantial moisture...some of it of tropical
origins...and spreading it across our area beneath a 110 knot
upper level jet. after a brief period of rain spreading onshore
late tonight and friday morning...the heaviest period rain will be
late friday night and saturday morning as a strong disturbance
moves through. additional rain is expected saturday night into
early sunday as another front moves through.
in addition...a strong surface low is now forecast to move north
along the coast later friday night and saturday morning. this may
bring high winds to the coast and over the coastal mountains...
with windy conditions also likely extending inland into the
valleys and over the cascades.
if all of this comes together as expected...this rain will likely
ease the dry fire conditions dramatically over southwest
washington and northwest oregon for at least the next week or two.
the rain and the wind will cause problems for those with outdoor
activities planned for this weekend. snow levels will generally
stay above 8000 feet...but climbing area mountains is not
recommended.
in addition...oils that have built up on roadways during the
extensive period of dry weather this summer will cause the roadways
to be extra slippery during the first part of the coming rain event.
be sure to slow down and use caution...and leave extra space between
you and the vehicle ahead of you.
