<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">A strong upper level ridge of high pressure lies on an axis from southern Nevada to northern Idaho. Offshore a deep upper level trough lies about 600 miles west-southwest of San Francisco and an upper trough is just off the
British Columbia coast. At the surface the highest pressures are over western Montana and northern Colorado, while a reflection of the upper level low off the California coastline is located west-southwest of San Francisco. The net result is a light north
or northeasterly flow most areas. Mixing heights along the coast will be suppressed. South Cascades mixing heights should be 5000 feet or better by this afternoon. Smoke dispersal conditions will be fair to good over the region. </div>
