<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper low that brought wet, cool weather to the Pacific Northwest has been slow to move out but by Thursday afternoon should be just a memory. There may still be some scattered showers around but by afternoon skies should
turn to partly cloudy to mostly sunny. Transport winds will be generally northwesterly to westerly. Mixing heights should remain high for favorable smoke dispersal conditions. </div>
<div> </div>
<div> OUTLOOK (FRIDAY-SUNDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Overnight Thursday a Pacific weather system approaches Oregon from the southwest. Rain will reach the southwestern part of the state early, and some light rain will spread east of the Cascades during the day. Transport winds
should be generally southerly most areas. Smoke dispersal conditions should remain favorable. Another Pacific cold front approaches during the day on Saturday and ushers in a moist west-southwest flow over the region that will continue Sunday for wet weather.
Mixing heights remain favorable for good smoke dispersal throughout the outlook period.</div>
