<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>

<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper trough that has been over the area finally moves east but another, minor, upper disturbance moves into southern British Columbia and western Washington tomorrow. I anticipate little, if any, precipitation from this
system. On the other hand, continued instability may be enough to touch off an afternoon shower or thunderstorm over the southern Cascades on Tuesday. Mixing heights should remain favorable for fair to good smoke dispersal, but a generally westerly transport
flow will limit opportunities in the coast range and especially near corridors leading to the Willamette Valley.</div>
<div style="padding-left: 36pt; "> </div>
<div> </div>
<div> OUTLOOK (WEDNESDAY - FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">As a generally west-to-east flow sets up aloft a minor ridge of high pressure moves through the region Wednesday and Thursday. Mixing heights remain fairly high and smoke dispersal conditions remain fair to good. Transport
winds stay generally westerly. Mixing heights are suppressed somewhat by Friday but fair to good smoke dispersal conditions will continue during the afternoons. </div>
