<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> MONDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">The weather system that brought rain to much of the Pacific Northwest Sunday is well to the east and dissipating by Monday. There will be slight ridging aloft and surface high pressure centered offshore. Skies will be generally
partly cloudy with good mixing heights for generally fair to good smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Weak high pressure aloft develops over the region Thursday. Expect partly cloudy skies. However, warmer temperatures aloft will stabilize the atmosphere and hold down afternoon maximum mixing heights for only marginal smoke
dispersal conditions for the northwest zones and fair to good conditions elsewhere. Another weather system brings rain back to the area by early Wednesday. Amounts will be mostly less than three-tenths of an inch. Mixing heights will still be suppressed
for just fair smoke dispersal conditions except for fair to good conditions in southeastern zones. Thursday will see scattered showers but cooler conditions aloft should improve smoke dispersal conditions. </div>
