The Snapshot: This beautiful fall weather will last through
Saturday. Rain starts on Sunday, dry
Tuesday. Then things get interesting.
The Science: While Cat 3 Hurricane Olaf
is churning up the winds and the waters to the south, the jet stream is
beginning to shift north and pull in some cooler air. Couple this with this critical time of year, weather
geeks are surely sitting on the edge of their seats. There is some very interesting movement
happening in the North Pacific Atmosphere.
Cliff Mass is honing in on the same thing: http://cliffmass.blogspot.com/
Yesterday’s forecast is still on track with beautiful dry and clear
weather through Saturday with rain entering the scene on Sunday/Monday.
Things get interesting on Wednesday when the storm track takes aim at the
PNW. This is pretty far out to get swayed by details that will surely change, but;
long range models show a large low-pressure system strengthening over the North
Pacific waters next week. This storm system
has the potential to usher in the season’s first round of heavy
precipitation. Rain will be the moisture
type for Stevens Pass with freezing levels 6500’ and higher for this first
round. However, cold air filtering in from the
Bearing Sea later in the week indicates a seasonal shift to the weather
pattern. As Cliff Mass alludes to in
his blog, this is typically late October early November seasonal shifts. A promising sign that things are changing as
they should be, winter is approaching.
