Greater Portland Metro Area

 Special Statement  Statement as of 2:52 PM PDT on September 22, 2014

... The first organized frontal system of the season to bring rain
and much cooler temperatures to southwest Washington and northwest
Oregon on Tuesday and Wednesday...

The fall equinox occurs at 729 PM PDT Monday. Right on cue... the
first organized frontal system of the fall will begin to move
onshore Tuesday. Expect widespread moderate to heavy rain to
accompany the front as it pushes across the region later Tue into
early Wed... along with some gusty winds along the coastal beaches
and headlands. This system will also usher in a showery and
significantly cooler weather pattern that will last through the
remainder of the week.

Rainfall totals from Tuesday through the end of the week are
expected to reach near an inch over the interior lowlands... and 1
to 2 inches for the coast and mountains. The colder air mass will
bring snow levels into the high Cascades... and some of the higher
mountain ski resorts may even see some snowflakes. Motorists are
urged to use caution on the roadways over the next few days.
Given the long period of dry weather that has preceded this
front... residual oil and grease on the Road surfaces will likely
become quite slick at the onset of the rain.
