<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 cold front that passes through the region Sunday evening ushers in a cool upper level trough that will bring numerous showers to the area Monday. Snow level will likely be near three thousand feet in the north and three
to four thousand feet in the south. Greatest precipitation totals will be in the north. Transport winds will be generally westerly except northwesterly in extreme southwest Oregon. With the cool air aloft mixing heights will give good to excellent smoke
dispersal conditions.</div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY - THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level trough axis will move east of the Cascades on Tuesday but cold impulses moving down from the north will keep showers going throughout the day. Transport winds will be generally northwesterly. By Wednesday
the showers will be mostly over except over the Cascades. A dryer northerly flow aloft takes over in advance of an upper level ridge offshore. On Thursday that ridge will move over the region for dry weather but much suppressed mixing heights and only poor
to fair smoke dispersal conditions. </div>
