<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Tuesday, November 10, 2009 2:30 PM Jim Trost</div>
<div> </div>
<div>NOTE: The forecast office will be closed Wednesday, November 11<font size="1"><sup>th</sup></font> in observance of Veterans Day. A forecast and instruction will be issued by approximately 8:00 AM Thursday morning.</div>
<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 28pt; ">Next upper level trough moves toward the coast bring rain to most of western Oregon. Amounts heavier in the north. Low level flow southwesterly early, shifting to more west to northwest in the afternoon. Air mass tends to
destabilize as the trough nears but mixing still a bit limited in the afternoon. Daytime smoke dispersion fairly good but mixing worsens quickly in the evening. This could create problems for residual smoke from units near SSRAs.</div>
<div> </div>
<div> OUTLOOK (THURSDAY - SATURDAY)</div>
<div> </div>
<div style="padding-left: 28pt; ">Unsettled weather continues to the weekend. Then on Saturday a ridge drifts over the Pacific Northwest. This will bring the mixing height down somewhat. Periods of rain or showers likely through Friday but with the ridging,
Saturday should be mostly dry. Organized transport and fair mixing should facilitate burning through the period.</div>
