<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Thursday, October 15, 2009 2:30 PM Nick Yonker</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; ">Upper level ridge has built over the region today diminishing the rainfall activity but still allowing plenty of cloud cover. This ridge will slowly slip to the east tonight and Friday allowing a very wet front to move into
the northwest corner of the state tomorrow. Models show this front stalling as it moves into northwest Oregon and dumping plenty of rain. Most other parts of the region, including the southwest and the Cascades eastward, will see very little, if any, rain
tomorrow. Air mass will remain fairly stable as warm air remains aloft. Areas where low level warming occurs due to less cloud cover will have better mixing. Breezy southerly wind flow will provide good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough and front finally push through the region Saturday and Saturday night after being stalled along the coast from Friday. Rain will decrease later Saturday. Minor ridging builds in Sunday, then will be followed
by yet another front and upper low Sunday night and Monday. Air mass will destabilize Saturday as the first front and trough move through. Air mass stabilizes some on Sunday, and then destabilizes again Monday. Smoke dispersion will be mostly good to excellent
through the period.</div>
