.DISCUSSION...
A flat ridge of high pressure aloft will nose into the region with
plenty of upper level moisture, leading to mostly cloudy skies. Winds
will be diurnally driven Sunday morning. But as a surface pressure
trough sets up east of the Cascades, winds will be more northwest
Sunday afternoon into Monday especially on the ridge tops.
Temperatures will warm slightly on Sunday. Clouds will thicken Monday
and could see a weak shower but measureable precipitation is not
expected. This will raise humidities and cool temperatures slightly.
Drier and warmer weather is forecast for Tuesday into much of the
work week.
