<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 29, 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 will remain over the region tonight and into early Friday before flattening and giving way to a cold front late Friday and early Saturday. Currently the warm front is arcing over the ridge and spreading clouds
and light moisture over the state today. This will diminish tomorrow as the warm frontal zone moves off to the east. Air mass mixes out with the warm air aloft mixing down to the surface and improving mixing conditions, especially north. Brisk wind flow
will also assist in improving smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Cold front moves into the state early Saturday morning, gradually breaking apart as it moves through. Moisture amounts will be generally light. Upper ridge will then rebuild Sunday, stabilizing the air mass again. Ridge
moves off to the east Monday as another weak front approaches. Air mass will remain stable and smoke dispersion mostly poor Sunday and Monday after a good day on Saturday.</div>
