<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">Upper level flow over the region will be generally west-southwest ahead of an upper level low pressure area about 600 miles offshore. Expect increasing high clouds from a weak warm front moving south to north over the region.
Transport winds will be generally southerly and mixing heights should be high enough to provide for good smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">By Wednesday the upper level low will be about 100 miles west of Grays Harbor, Washington. Upper level flow will be from the southwest with enough moisture for scattered showers. The upper low moves across northern Washington
on Thursday with an upper trough sweeping across Oregon. This will keep showers going. By Friday the trough will be on an axis from northern Idaho to central Nevada and moving east. Flow aloft will be north or northeasterly. There will still be enough moisture
for widely scattered showers. Maximum mixing heights should reach 5000 feet or above through the outlook period for good smoke dispersal conditions. </div>
