<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> </div>
<div style="padding-left: 36pt; ">Front and upper level trough are moving through the region today with the bulk of the moisture over the northwest corner of the state. Minor ridging builds in overnight and into Sunday providing some modest stabilization.
Next front and trough, which takes a more southerly track, will approach Sunday evening. Expect mostly cloudy skies on Sunday with some sun breaks, then increasing clouds again later in the day. Wind flow will be fairly light but with decent afternoon mixing,
will make for fair to good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (MONDAY - WEDNESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Front and upper level low move into the state early Monday providing another shot of moisture with the heavier amounts over the southern part of the state this time. Low moves through Monday afternoon and gives way to a minor
ridge that will develop over the state on Tuesday. Again, this ridge will provide just brief and minor stabilization. Another minor front will approach early Wednesday bringing some more light rain to mostly the north half of the state. Smoke dispersion
should be mostly good through the period under this progressive weather pattern.</div>
