<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper level trough that brought rain to many parts of Oregon shifts to the east on Wednesday. Weak ridging aloft moves in to cut off any remaining showers overnight and give dry weather during the day. Mixing heights
in coastal zones and the interior valleys will allow fair smoke dispersal conditions with good conditions likely in the Cascades. Transport winds will be generally northerly or slightly northwesterly.</div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Weak ridging aloft continues Thursday for dry weather. Temperatures climb to above normal levels. Most zones will see marginal to fair smoke dispersal conditions while conditions in the Cascades will be good. Transport winds
remain north to northwest. Friday and Saturday a generally west-to-east flow in the upper atmosphere will prevail, but with minor impulses rippling past in the flow. These could touch off afternoon or evening thunderstorms mainly over mountainous regions.
Smoke dispersal conditions will be marginal to fair along the coast and the interior valleys, but good in the Cascades. </div>
