<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> WEDNESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low pressure area continues to spin over the Pacific Northwest on Tuesday. Low level flow will be onshore for mostly cloudy skies. With the cool air aloft with the low scattered showers are likely, especially
for the northern zones. Mixing heights will climb to three to four thousand feet most areas for fair to good smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level low dissipates Thursday but a broad trough remains over the region. Weak onshore flow continues most areas for partly to mostly cloudy skies and a continuing chance of showers. Smoke dispersal conditions will
be good most areas. The trough remains for Friday but weakens and finally by Saturday weak ridging begins to build offshore. Showers are still possible although moisture will be very limited. High mixing heights should give good smoke dispersal conditions
for the end of the week. </div>
