<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low that brought clouds, rain and cool temperatures to the Pacific Northwest will track west to east across the state on Wednesday. This will keep showers going thought the area. The cool air aloft with this system
will keep mixing heights high and smoke dispersal conditions should be good to excellent. Transport winds, however, will be highly variable in direction. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY - SATURDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">On Thursday the upper low slowly pulls out to the east allowing weak ridging to build. Mixing heights should remain high for good to excellent smoke dispersal conditions. Winds will go offshore, generally east through northeast
across western Oregon. By Friday a Pacific weather system will approach from the southwest. Models differ on the initial strength of this system but for now it looks like rain reaching southwest Oregon early in the morning with precipitation spreading northward
to extreme northwest Oregon by Friday evening. A Pacific cold front moves onshore on Saturday and the weekend looks quite wet. Good smoke dispersal conditions through the outlook period, but shifting winds each day, and conditions likely too wet to burn.
