<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</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; ">An active Pacific cold front that was stalled over northwest Oregon on Monday will finally move eastward Tuesday. Rain with this system will occasionally be heavy. Late in the day, as the front moves east, some stabilization
of the atmosphere is likely, thus burning should begin early. Smoke dispersal conditions should be good to excellent throughout most of the day, deteriorating slowly in the late afternoon. </div>
<div> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Post frontal showers continue Wednesday. Mixing heights will be a bit lower than on Tuesday, but smoke dispersal conditions should remain moderate. However, warm overrunning conditions ahead of the next Pacific cold front
will put a lid on mixing heights. There is model disagreement on the timing of that next front. My best estimate is that it will stall similarly to the system on Monday/Tuesday and not reach the area until Friday. That means the most stable conditions will
likely be Thursday, with improving smoke dispersal conditions again on Friday. </div>
