.DISCUSSION...
Happy Thanksgiving! Today will be a nice day across the region.
The strong upper level ridge that is set up over the West Coast will
continue to keep the region under N to NW flow aloft today and
tomorrow. Southwesterly winds at the surface will be light today as
temperatures warm to the upper 70s.

Early tomorrow the upper level ridge becomes slightly flattened as a
system moves across the Pacific NW. At the surface lee side
troughing develops ahead of a surface cold front. Enhanced downslope
warming and winds will create near-record warmth and breezy
conditions Friday. This combined with low RH values will elevate
fire weather conditions to near-critical/critical on Friday. Friday
evening/night the associated cold front will cross the region. This
will drop high temperatures nearly 10 to 15 degrees Saturday. Sunday
the region warms back up as surface winds become southwesterly and a
as a surface high to the east builds and lee troughing develops.

Early next week the upper level ridge starts to move eastward as an
upper level Pacific trough moves on shore. Monday just ahead of the
positively tilted trough aloft another lee side trough enhances
downslope warming and winds. This will increase winds and warm high
temperatures above normal Monday and create a critical Fire Weather.
Models continue to show the upper level trough and associated cold
front moving through the area Tuesday evening. This make for breezy
to windy conditions on Tuesday and a decent cool down on Wednesday
but still no precip.
