<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Saturday, October 24, 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 continue building over the state today and tonight, further stabilizing the air mass. Next frontal system will override the ridge Sunday as a warm front spreads clouds over the area during the day with
light rain beginning during the mid to later afternoon. Moisture will continue spreading eastward over the Cascades Sunday night. Increasing wind flow from the southwest will slowly improve smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (MONDAY - WEDNESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Ridge slides to the east early Monday giving way to the cold front and upper level trough. Expect a fairly generous amount of moisture over the region. Cooler air will move in aloft to destabilize the air mass and lower snow
levels. Upper trough moves by to the east Tuesday but with a strong northwesterly jet stream over the region, cool showers will continue with the snow level lowering to near 3000 ft. Air mass will be quite unstable. The next upper level ridge starts building
in Wednesday but with chilly air remaining over the region, the air mass will remain mostly unstable. However, decreasing wind will worsen smoke dispersion from the dispersion of Monday and Tuesday.</div>
