<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div style="padding-left: 36pt; ">A very slow moving upper level low pressure area remains off the California coast on Wednesday. Counter-clockwise flow around that low will again spread moisture northward into Oregon. Daytime heating will destabilize the
atmosphere and thunderstorms will again be a possibility. Best chance afternoons and evenings over mountainous areas. Low level flow will be southerly, switching to southwesterly in the north. Southern zones will see southwesterly winds switching to northwesterly.
Mixing heights will be high enough to provide for marginal to fair smoke dispersal conditions in coastal sections and good conditions in the Cascades. </div>
<div style="padding-left: 36pt; "> </div>
<div>OUTLOOK (THURSDAY – SATURDAY)</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper level low finally moves into California with flow aloft becoming more easterly or northeasterly over the state on Thursday. The atmosphere will still be unstable and there will still be moisture available for thunderstorms.
The greatest threat of thunderstorms will be in southern sections. Smoke dispersal conditions will be about the same as on Wednesday. By Friday the upper low will be over central California with a dryer flow aloft. The threat for afternoon and evening thunderstorms
continues. Winds will be generally west-northwest. By Saturday upper flow goes more northerly. The slow moving upper low drifts into Nevada and another upper low forms in Alberta. The atmosphere will remain a bit unstable, but with diminished moisture the
threat of thunderstorms decreases considerably but smoke dispersal conditions remain favorable. </div>
