<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>

<div> </div>
<div>ISSUED: Wednesday, December 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 style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">** Cold weather developing for the weekend **</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper ridge will cover the eastern Pacific on Thursday with upper flow generally northerly over the Pacific Northwest. This is a dry pattern with cool night-time temperatures. In the north offshore flow will be quite brisk
but expect only light easterly flow in the south. Mixing heights will be low for poor to marginal smoke dispersal conditions. </div>
<div> </div>
<div> </div>
<div>OUTLOOK (FRIDAY-SUNDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">On Friday an upper level trough over southwest Canada will drop south-southeast into the region. Moisture will be limited but there is a possibility of some snow flurries with this system. The low will settle in over the
area for Saturday and Sunday. Models differ on the exact location and configuration of this low but there seems to be consensus on only limited moisture. Temperatures will be very cold, coldest of the season, and there will be a continued possibility of snow
flurries. With the upper low mixing heights will rise for improved smoke dispersal conditions. </div>
