<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Cold front pretty much fell apart as it came in last night. Ridge has rebuilt and is keeping the air mass quite stable. Next warm front arrives on Saturday increasing the rain during the morning. Expect continued stable
conditions with light to moderate SE to S winds. Smoke dispersion will remain poor to fair.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Cold front moves in on Sunday bringing more rain and stronger wind. Air mass destabilizes. First upper trough will then follow through late Sunday. Another cold front and stronger trough moves in Monday bringing more moisture
and considerably cooler air aloft. Snow level will drop to 1500 – 2500 ft Monday night. Upper trough will move through late Monday and off to the east on Tuesday. Air mass will destabilize further Monday and remain unstable Tuesday. Expect good to excellent
smoke dispersion through the period.</div>
