<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge is sliding to the east today and will give way to a frontal system that will slowly move in on Thanksgiving. Moisture will begin along the north coast early in the morning and spread south and east through
the day. Air mass will slowly destabilize during the day but remain mostly stable until overnight when the cooler air moves in aloft. Winds will increase from the south and provide good smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (FRIDAY - SUNDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough moves in early Friday morning bringing cool, showery, and unstable conditions. Snow level lowers to 2000 – 3000 ft. An upper ridge will then follow on Saturday and strengthen on Sunday. Expect good smoke
dispersion Friday, decreasing dispersion Saturday, and rather poor dispersion on Sunday.</div>
