<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">A complex upper air situation in progress during the day on Tuesday. An upper level low will retrograde westward across central British Columbia and a second upper level low will move toward Oregon over the ocean from the
southwest. The two systems will combine for southwesterly flow aloft and a Pacific cold front will spread rain into the region. Amounts will be significant, greatest since last spring most areas, however the heaviest rains will actually move into northern
California. </div>
<div> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Expect post-frontal showers on Wednesday. Snow levels should be 7000 feet or above. Mixing heights should be quite high for good smoke dispersal conditions. On Thursday a front moves mainly into northwest Oregon and western
Washington. Some scattered showers may continue in the area. By Friday dry weather will return to the area. Mixing heights should be high enough to allow for fair to good smoke dispersal conditions. </div>
<div> </div>

<div>==================================================================</div>
<div> </div>
<div style="padding-left: 36pt; ">Avoid ignitions within 10 miles to the S through SSW of SSRAs. For units that will smolder significantly through the night avoid burning within at least 10 miles to the S through SW in or near drainages leading to SSRAs.
Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. No additional restrictions necessary. </div>
