<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level trough that was over the region on Sunday weakens and moves to the east but no significant ridge develops. In fact another weak upper trough moves out of southern British Columbia into northern Washington.
At the surface weak high pressure noses into northwestern Oregon and a thermal trough develops in northern California and extends off the southwestern Oregon Coast. This will give a generally northwesterly transport flow to most areas although southern coastal
sections should see a northerly or north-northeast flow. Mixing heights should be high enough for good smoke dispersal conditions. </div>
<div> </div>
<div> OUTLOOK (TUESDAY - THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level winds are generally westerly on Tuesday but a fast-moving upper disturbance rides the flow into the Pacific Northwest on Wednesday. A weak surface front associated with this feature should bring some light rain
to northwest Oregon late Wednesday and early Thursday morning. Transport winds will be generally northwest to north on Tuesday, switching to southwest to west ahead of the weak front on Wednesday, then back to north to northwest on Thursday. Mixing heights
will remain high and smoke dispersal conditions good. The westerly component to the transport winds will make burning in the north coast range problematical. </div>
