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

<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Flat ridge over the state today is keeping skies mostly fair but an upper level trough will develop to the northwest and move in on Friday. Expect increasing clouds with a chance of some light showers. Because the system
is dropping down from the northwest, moisture will be light and limited. Cooler temperatures will follow Friday evening with the snow level dropping down to 4000 – 5000 ft. Air mass will remain mostly unstable, and with light to moderate NW flow, will make
for good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low continues to drop southward Sunday and forms into a chilly upper level low over the state. This low will gradually slip to the southeast Sunday leaving the region under chilly northerly to offshore flow through
Monday. Air mass will remain mostly unstable except for brief late night and early morning stability. Air mass will dry Monday as moisture moves off to the east with the low and a high pressure ridge noses in from the west.</div>
