Monday November 2
California is getting much needed rain from the leading
edge of our Halloween weekend storm which dumped
a lot of rain the Eugene – Springfield area. The system
provided an amazing volume of water in a short period
in many areas of the PNW, causing localized flooding
including INSIDE a Portland light-rail train. For most of
the days this week in the PNW, showers will pop up here
and there. There remains the potential for FROST, should
the sky clear overnight Tue or Wed. Watch AM temp forecasts.
LOTS OF RAIN and mountain SNOW is coming. In fact,
flood issues may very well be a key attribute of the upcoming
wx pattern. The WET system following behind Thursday's
'maybe rain' disturbance will arrive by Fri night. Colder air
behind the storm will usher in a good amount of snowfall in
the mountains, along with rain & progressively heavier
showers in the lowlands on both sides of the Cascades. This
is modeled for late Fri on through Monday night, Nov 9.
'Southern and eastern OR could be slow to experience this
particular storm serious, but by Sunday, everyone should be
in on the action. Current charts do NOT indicate the weekend
storm to be as wet as our Halloween Day storm.
Next will be a stronger front, timed to drop down from the
NW Tue/Wed Nov 10,11. WINDY with heavy rain. A lot more
SNOW in the mountains. It will turn notably colder at the
surface for everyone. By Friday the 13th, a strong, windy,
VERY WET "double punch" storm surge will arrive. With
moisture training from Japan all the way across the pacific
directly into the PNW, moderate-to-heavy rain bands will
repeatedly slam into the region. The winds will be moderately
strong, as well. Depending on which model run we accept,
winds could approach damaging levels Sat/Sun, Nov 14,15
esp given what will be saturated soils by that time.
