<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level ridge that moved over the region over the weekend will flatten and move to the east while an upper level low pressure area will move into central California on Tuesday. At the surface a thermal trough will shift
inland. Transport winds will initially be from the east but shift to westerly during the day. Because of shifting winds recommend burning only units well away from populated areas. Mixing heights should remain favorable for fair to good smoke dispersal
conditions.</div>

<div> OUTLOOK (WEDNESDAY - FRIDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">The California upper low will shift into Nevada and Utah on Wednesday. Expect some light rain most areas with this system for Wednesday. Another weather system will spread more rain in again for Thursday and Friday. </div>
