<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; ">The jet stream shifts northward on Wednesday as high pressure builds aloft. Dry weather will prevail across the entire Pacific Northwest. Temperatures should be up about five degrees from Tuesday. Mixing heights at the coast
will be somewhat limited but during the afternoon should provide for fair smoke dispersal. Cascades will see good to excellent smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper level high pressure area continues to build. The high center will be over the Great Basin and clockwise flow around the high could bring some moisture north for the possibility of afternoon or early evening thunderstorms
Thursday and Friday, mainly over the southern Cascades. Mixing heights will remain favorable for good smoke dispersal conditions. A weather system moving across British Columbia flattens the ridge Friday and turns upper flow more southwesterly with lessons
the chance for thunderstorms. </div>
