<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>

<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Pesky upper level low finally weakens and opens up into a minor trough for Sunday. This will mean less shower and thundershower activity that has plagued the state the last several days. Expect less cloud cover and slightly
warmer temperatures. Air mass will remain mostly unstable and wind flow light, thus leading to continued fair to good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (MONDAY - WEDNESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Weak upper level trough remains off the coast Monday but drifts to the south, leaving the region under a split flow for Tuesday. A minor trough will move through later Tuesday to Wednesday and bring a modest marine push to
the region. Expect mostly sunny skies and warm temperatures Monday and Tuesday. Marine push will likely bring some cloud cover into the western interior on Wednesday. Air mass will stabilize more during the night and morning hours but destabilize pretty
well during the afternoon. Smoke dispersion will remain mostly fair, and then improve Wednesday under the marine air.</div>
