<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough from this morning’s disturbance is moving off to the east this afternoon. The next trough and disturbance will move in Saturday bringing a renewed surge of cool marine air and scattered light showers. Snow
level will lower to near 6000 ft in the mountains. Cool air aloft on Saturday will make for excellent mixing and good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough will form into an upper low to the north in Washington on Sunday. This will keep cool, moist, and unstable air over the region. Upper low will gradually weaken and move eastward bringing slow warming and
drying Monday. An upper ridge will move in Tuesday bringing considerably warmer conditions. Air mass will stabilize during the night and morning hours Tuesday but become fairly unstable during the afternoon. Smoke dispersion will start out good Sunday, and
then gradually worsen Monday and Tuesday.</div>
