<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>

<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> TUESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">A weak upper level ridge slowly moves east over the region during the day on Tuesday. Low level flow will be mostly onshore for clouds on the coast and just partly cloudy skies in the interior. Coastal temperatures will generally
be 3-5 degrees below average while interior locations will see temperatures near to about 5 degrees above average. Cooler surface temperatures in the coastal zones will hold afternoon mixing heights down a bit while interior locations should see fair smoke
dispersal conditions and areas east of I5 will see good conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The weak upper ridge moves east and is replaced by southwesterly flow aloft on Wednesday. Low level flow remains onshore. Coastal temperatures remain 3-5 degrees below average while interior locations will be near average.
A disturbance in the SW flow aloft may produce afternoon thunderstorms over the Cascades. Mixing heights will rise high enough to give fair to good smoke dispersal conditions. Thursday will see a broad trough over the area but moisture will be limited. Expect
mostly cloudy skies most areas. Smoke dispersal conditions will be fair along the coast and fair to good elsewhere. On Friday the broad tough moves to the east and a cool northwesterly flow aloft develops. Temperatures will generally be 5 to 8 degrees below
average with smoke dispersal conditions similar to Thursday. </div>
