.DISCUSSION...A gradual warming and drying trend will continue through
early next week. At this time, this afternoon into Monday look to be
the driest days with minimum RH values in the 20-35% range, with the
lowest values being located within the southern Cascade foothills.
Tuesday will continue to remain warm and dry, with temperatures
above average and minimum relative humidities in the 20-30% range,
primarily in the foothills. Troughing will develop on Wednesday,
which will help moderate temperatures and increase onshore flow
across the region and bring slight chances for showers by late week.
Forecast for 20 foot wind speed (valleys and ridge tops) are 10
minute averages reflecting RAWS winds.
