<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Monday, November 2, 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; ">** Stable Pattern – Poor Smoke Dispersal Conditions Continue **</div>
<div> </div>
<div style="padding-left: 36pt; ">A weak pacific weather system moving through British Columbian and northwest Washington Monday and Monday evening will be well to the east of the area tomorrow. This will allow the upper level ridge to strengthen for very
stable conditions over the region. Expect fair weather but low mixing heights, light winds, and generally poor smoke dispersal conditions. Winds will generally be light north or northeast except light south or southeast in the southern Cascades and the Rogue
Valley. </div>
<div> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Wednesday is a transition day as the upper ridge axis shifts eastward. Expect little improvement in northern zones but higher mixing heights for marginal conditions in southern sections. Mixing heights should be near or below
2000 feet most areas in the north. Winds will be generally light east through southeast becoming light south through southwest late. By Thursday an upper trough will be approaching as the upper ridge axis moves out of the northern Rockies and into the northern
plains. Winds aloft will be southerly and surface winds will pick up from the south. Rain will reach the northwest coast late and cover much of the region by Thursday night or Friday morning. Mixing conditions will be much improved. Friday expect cloudy,
rainy weather most areas with good smoke dispersal conditions and a generally southwest through westerly wind. </div>
