<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Friday, December 4, 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; ">Dry cold front and trough will drop down from the north this afternoon and evening and bring cooling temperatures aloft. Once the front moves through overnight, wind flow will increase from the NE to E and bring chilly surface
winds to the region. Air mass will destabilize some as the cooler air moves in. Smoke dispersion will become mostly good by tomorrow afternoon.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Another more arctic-like front will drop southward Saturday night to Sunday morning bringing very cold temperatures and the chance of some light snow or snow flurries Sunday. Air mass will destabilize completely and wind flow
will remain offshore. Cold pool of air settles in over the state for the rest of the period as the upper level low slowly moves to the south of the region. Decreasing wind flow and warming aloft while temperatures remain cold near the surface, will stabilize
the air mass again. Smoke dispersion will be the best Sunday then worsen Monday and Tuesday.</div>
