<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge will continue to build along the coast today keeping the air mass stable and wind flow light. Expect mostly sunny skies. Smoke dispersion will remain poor.</div>
<div> </div>
<div> OUTLOOK (THURSDAY - SATURDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge begins to weaken Thursday as a dry cold front approaches. Upper low behind the front will drop into the state from the north and bring much cooler conditions beginning later Friday. Wind flow turns onshore
and increases. As the low drops southward, cold arctic-like air will move in Saturday bringing the coldest conditions of the season. Wind flow turns offshore to northerly. Colder air moving in aloft plus increasing wind flow will improve smoke dispersion
considerably on Saturday.</div>
