<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</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; ">Upper air charts for Tuesday show a trough aloft with its axis extending from a low near the Queen Charlotte Islands southward to about 300 miles off the Oregon Coast. This gives southwesterly flow aloft over the region.
Low level flow will be onshore, generally northwesterly for northern zones and more north-northwesterly for the south coast range. The southern Cascades will see more of a westerly transport. Skies will generally be cloudy early then inland areas will see
partly cloudy to sunny skies in the afternoon. Temperatures will be 3 to 5 degrees below average on the coast and 5 to 10 degrees below average in the interior. In spite of cool surface temperatures the generally cool air mass over the region will produce
a vertical temperature profile that gives high afternoon mixing heights for generally good smoke dispersal conditions depending only on low level/transport wind direction. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Onshore flow and cooler than average temperatures will continue through the outlook period. A weak trough will remain over the area on Wednesday. Temperatures should be 3 to 8 degrees below average. Maximum mixing heights
will push to above 4000 feet most areas for good smoke dispersal conditions. A progressive disturbance moving across the Pacific Ocean deepens the trough over the area and could produce some rain in the north on Thursday. Low level flow will be onshore with
northerly surface winds most areas. The trough axis will pass to the east during the afternoon. Mixing heights should remain above 4000 feet most areas except the immediate coast. Temperatures will be 4 to 6 degrees below average for coastal areas and from
8 to 12 degrees below average in the interior. By Friday a cool west-northwesterly flow aloft will develop. Low level flow continues onshore, temperatures will run 4 to 8 degrees below average. Expect morning clouds with partial afternoon clearing most areas
with maximum mixing heights well above 4000 through much of the region. </div>
