<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Sunday, November 22, 2009 2:30 PM Jim Little</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; ">After a wet and stormy period the Pacific Northwest will finally settle down and dry out for a few days as high pressure aloft shunts any storms to the north of Oregon. The only exception will be a weak system that will drag
across northwest Oregon late Monday for some light rain. Otherwise subsiding air aloft will stabilize the atmosphere and lead to deteriorating smoke dispersal conditions through mid week. Winds will be generally southeast to east except light and variable
in the Rogue Valley and southwest Oregon. </div>
<div> </div>
<div> OUTLOOK (MONDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper ridge over the area strengthens Tuesday. Overnight surface inversions will break for only poor to marginal smoke dispersal conditions during the afternoon. On Wednesday the ridge axis moves east and upper flow shifts
southwesterly. However the ridge still dominates and burning conditions will be poor at best. Recommend against any planned burning for Wednesday. The ridge axis finally moves east and an upper trough approaches Thanksgiving day. A Pacific Cold front moves
into western Oregon in the afternoon for improving smoke dispersal conditions. </div>
