<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; ">An upper level ridge centered over the northern Great Basin will keep conditions warm into the first part of next week. Southerly flow will continue to produce enough moisture for the threat of afternoon and evening thunderstorms
mainly over the Cascades. Nighttime inversions will hold smoke close to the ground overnight and into the morning hours. During the afternoon mixing heights will improve smoke dispersal conditions to poor in the north Coast Range, and fair in the South Coast
range. Smoke dispersal conditions reach moderate during the afternoon in the Cascades. </div>
<div> </div>
<div> OUTLOOK (TUESDAY - THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level ridge slips slowly eastward and an upper level low moves slightly closer to the California coastline on Monday. Counter-clockwise flow around that low could bring some of the Cascade thunderstorms west into
the Willamette Valley or the Coast Range. The upper low remains off the California coast through the outlook period. Afternoon instability will help smoke dispersion, but the window for acceptable smoke dispersal conditions remains narrow with unfavorable
conditions evenings and mornings. </div>
