<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> MONDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">The upper ridge that brought sunshine to much of Oregon over the weekend moves east on Monday. The coastal low clouds of Sunday will penetrate interior valleys. This will hole temperatures down a few degrees. Except for
some spotty drizzle along the coast and in the coast range conditions should remain dry. Transport winds will be generally northwesterly. Smoke dispersal conditions should be fair to good. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level low drops down the British Columbia coastline and across northwest Washington during the day Tuesday. This will increase the southwesterly flow aloft. Some light rain is likely in the extreme northern zones
otherwise conditions will remain dry. Transport winds will be generally northwesterly. By Wednesday the upper low covers the Pacific Northwest, centered over the southern Washington Cascades. Moisture will be limited, but light rain is likely in the northern
zones, southern zones will remain dry. Subsidence aloft will suppress mixing heights for just fair smoke dispersal conditions most areas. There will still be an upper trough over the region on Thursday but very limited moisture. Some afternoon sun should
drive mixing heights higher for good smoke dispersal conditions. Wednesday and Thursday will see a continuation of a generally north or northwesterly transport wind. </div>
