<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Persistent upper level low to the south that provided several days of thunderstorm activity has finally weakened and moved to the east. An upper level trough is dropping down from the north today and keeping low level flow
onshore and skies mostly cloudy. Skies will clear a little more tomorrow as the trough shifts eastward and the low level flow weakens. Air mass should remain mostly unstable thus smoke dispersion will continue fair to good.</div>
<div> </div>
<div> OUTLOOK (MONDAY - WEDNESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level flow becomes rather non-descript over the extended period with light flow both near the surface and aloft. A weak trough appears to move in Tuesday increasing the chance of showers but mainly over the mountains.
Air mass will stabilize more during the night and morning hours but destabilize during the afternoon. Smoke dispersion will remain mostly fair to good.</div>
