<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> MONDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low will drift to within about 300 miles west of the NW tip of Vancouver Island. Upper flow will be from the SW over Oregon. A very weak, but mostly dry, front will push into NW Oregon for more clouds than
Sunday. Temperatures will be near to slightly below average except in the Rogue Valley where slightly above average temperatures are likely. Low level flow will be onshore, generally west or northwest, and cooler surface temperatures in the coastal zones
will hold mixing heights down a bit. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low moves into southern British Columbia and the air mass continues to cool on Tuesday. Temperatures drop to generally 5 to 8 degrees below average. Cooler temperatures aloft will help maximum mixing heights to
bump up from Monday. Low level flow remains onshore. Wednesday and Thursday will see the upper low pull out into central Canada, leaving a cool trough over the region. Temperatures will be around 5 to 10 degrees below average and low level flow will remain
onshore. However, the cool air aloft should help maximum afternoon mixing heights to near 5000 feet most areas for good smoke dispersal conditions depending on wind direction. </div>
