<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; ">A Pacific weather front moves through the region Sunday night followed by another surge of moisture Monday morning. Expect wet weather all of western Oregon during the day. Amounts of one inch are possible. Cooler air aloft
filters in behind these weather systems and snow levels lower to below the Cascade passes. Snow amounts of 10 inches are possible above about 4000 feet by Tuesday morning. Mixing heights should provide for fair smoke dispersal conditions most areas. </div>
<div style="padding-left: 36pt; "> </div>
<div> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level ridge builds in the eastern Pacific. Post frontal showers continue on Tuesday. By Wednesday just widely scattered showers are likely. Mixing heights remain high enough for fair to good smoke dispersal conditions.
The ridge in the eastern Pacific pushes the next surface low well to the north into southeast Alaska, but a warm front extends southward from that low and clips Washington and Oregon for some light rain in much of western Oregon on Thursday. Warmer air aloft
will suppress mixing heights somewhat, but smoke dispersal conditions still look generally marginal to fair for the end of the week.</div>
