<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>

<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> TUESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low remains about 6000 miles west of Vancouver Island on Tuesday. Counter clockwise flow around that low drives a Pacific weather system mainly into northern California but enough moisture spreads northward
for periods of rain throughout the region. Mixing heights will be high enough for fair to good smoke dispersal conditions. Transport winds will be generally south to southeast except light and variable in the northern Cascades.</div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY) </div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">The upper low elongates on a NW/SE axis but remains offshore on Wednesday. Upper flow will be from the south or southeast across Oregon. There will be enough moisture for scattered showers, but by evening they should be
mainly over the cascades. By Thursday the upper low consolidates off the southwest Oregon coast. Moisture continues to stream around the low and spread south to north across the region. The low finally drifts east and a drier northerly flow sets up across
the region. Expect dry weather, and with some sunshine, warmer temperatures. Smoke dispersal conditions should remain fair to good throughout the outlook period. </div>
