<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level low remains in the Gulf of Alaska on Tuesday with a strong west to east upper flow over the eastern Pacific and the Pacific Northwest. Post frontal showers will continue throughout the day. Maximum mixing heights
will be above 5000 feet for good smoke dispersal conditions and transport winds will be generally southwesterly. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">A slow moving Pacific cold front will move across the region on Wednesday for periods of rain throughout the day. Mixing heights will remain high and transport winds will be southwesterly. On Thursday a strong westerly flow
aloft continues, while at the surface high pressure begins to build west of California. The surface high will be too distant to have much effect on Oregon weather with scattered showers continuing. By Friday the surface high will finally begin to nose into
the Pacific Northwest cutting off showers. Low level transport winds will finally shift to more northerly by Friday. Smoke dispersal conditions remain good. </div>
