248 PM PDT Sat Aug 9 2025
...HEAT ADVISORY IN EFFECT FROM 2 PM SUNDAY TO 10 PM PDT TUESDAY...
.DISCUSSION...A gradual warming and drying trend will continue through
the weekend into early next week. At this time, Sunday and Monday
look to be the driest days with minimum RH values in the 25-35%
range, with the lowest values being located within the southern
Cascade foothills. There is some uncertainty into how much cooler
and more moist air arrives Tuesday. Troughing will develop by midweek
of next week, 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.
