<li>DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</li></ol>
<div style="padding-left: 24pt; "> </div>
<div style="padding-left: 48pt; ">Weather this week will be dominated by high pressure aloft, with the axis of the high pressure remaining offshore. Temperatures aloft should remain cool enough for good mixing heights, however. Transport winds will be generally
light and have a northerly component. </div>
<div style="padding-left: 24pt; "> </div>
<div> OUTLOOK (WEDNESDAY - FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper ridge will remain more-or-less stationary with a generally northerly or north-northwesterly flow aloft over the region for continued fair weather. Temperatures aloft should stay cool enough to allow mixing heights
to be high enough to provide fair to good smoke dispersal conditions throughout the outlook period. </div>
