<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> TUESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low drops in from the northwest during the day Tuesday. This will keep skies mostly cloudy and there will be a little light rain. Totals will generally be less than a tenth of an inch. Relatively cool air
aloft will destabilize the atmosphere and help push maximum mixing heights to above 5000 feet. Low level flow will be generally onshore or northwesterly during the day except more northerly transport winds are likely over the south coast range. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low moves southeast into southern Idaho on Wednesday. Cooler daytime temperatures will limit maximum mixing heights a bit but smoke dispersal conditions should be at least fair to good most areas. Expect a chance
of light rain. By Thursday the upper level low will move east northeast into south-central Canada. Flow will continue mostly onshore but the rain will be ending during the day. Friday looks dry but cloudy. Mixing heights both Thursday and Friday should
be fairly high yielding generally good smoke dispersal conditions. </div>
