<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 will remain over the region through tomorrow with the axis near the Oregon/Idaho border. Expect continued sunny skies and warm temperatures. Some convective buildups will form over the Cascades, giving a
chance of some late afternoon to evening thundershowers there. Air mass will remain mostly stable with afternoon heating providing a brief period of good mixing over inland locations. Wind flow will remain light and favor a generally northerly direction.
Smoke dispersion will be poor to fair.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge remains over the region and to the east through the weekend, gradually weakening and allowing an upper low to approach for Monday. Expect continued sunny skies and warm temperatures with a chance of afternoon
to evening thundershowers over the Cascades. Air mass will continue stable during the night and morning hours with some instability during the afternoon. Wind flow will also remain light leaving the region under poor to fair smoke dispersion.</div>
