<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">A Pacific weather system moves in from the west-southwest during the day Wednesday. Rain reaches the coast early afternoon and covers all of western Oregon by early evening. Mixing heights remain high for good smoke dispersal
conditions. Transport in winds in the north start out southeast then become more southerly as the front approaches and its parent low tracks into western Washington. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">High pressure aloft builds on Thursday. Showers are sill possible early in the day but should end as the air mass stabilizes. Mixing heights should remain favorable for good smoke dispersal however and transport winds will
be generally southwesterly. Expect continued high pressure aloft on Friday and Saturday for dry weather. Nighttime inversions will trap residual smoke near the ground but daytime heating should push mixing heights to the 3500 to 4500 foot range for fair
to good smoke dispersal conditions. Transport winds late in the week will be generally northwesterly to northerly. </div>
