<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">During the day on Wednesday an upper level low consolidates west of southern British Columbia. Post frontal showers continue through the day. Mixing heights should be generally favorable for good smoke dispersal. Transport
winds will be generally southwesterly. </div>
<div> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low weakens and moves northwest slightly allowing higher pressure to build aloft. The ridge axis will be over eastern Oregon/eastern Washington. This will give mostly dry weather to the region. Mixing heights should
still be high enough for fair to good smoke dispersal conditions on Thursday. The ridge axis shifts slightly east on Friday but dry weather will continue. By Saturday the remains of a weak front will move through giving a chance of light rain. </div>
