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

<li>DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</li></ol>
<div> </div>
<div style="padding-left: 24pt; ">A network outage at the state data center precluded me from seeing any weather data up until just before forecast time. Thus this is a hurried forecast with low confidence. An upper low over southern Alberta will move slowly
east early in the week. Another upper trough of low pressure will push onshore from the west into the Pacific Northwest by mid week. Mixing heights appear favorable for good smoke dispersal conditions during the afternoons. Winds will tend to onshore.</div>
<div> </div>
<div> OUTLOOK (TUESDAY - THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Computer models indicate a split flow through the outlook period, but there are model differences on key features. Expect an onshore flow, decent mixing heights, and a slight chance of rain each day.</div>
