<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Monday, October 26, 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; ">The wet Pacific cold front that brought considerable rain to western Oregon Monday will be well to the east and dissipating. The cool upper trough supporting that system will move to the northern Rockies leaving a cool northerly
flow aloft over Oregon. This will keep the atmosphere destabilized with mixing heights above 4000 feet most areas. Winds will remain brisk for favorable smoke dispersal conditions most areas. Expect scattered showers, occasionally heavy, during the day,
gradually dissipating by late afternoon. </div>
<div> </div>
<div> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level ridge builds in the eastern Pacific and moves over the region on Wednesday. Weather will be dry, however the ridge will progress to the east and allow another Pacific warm front to approach Wednesday evening.
Expect rain Wednesday night and then more rain Thursday as a cold front sags across the Pacific Northwest. Friday will see showers with another Pacific cold front due in on Saturday. Mixing heights should remain high enough for good smoke dispersal conditions
through the outlook period. </div>
