<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 continues to build over the state today and will remain strong over the region tomorrow as well. Air mass will remain stable except for a brief period of good mixing during maximum afternoon heating. Expect
sunny skies and temperatures in the 80s at inland lowland locations. Wind flow will be light, favoring a northerly direction. Smoke dispersion will be mostly poor to fair.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper ridge remains strong over the region Sunday and even into Monday. A frontal system that was supposed to arrive later Monday appears much weaker and delayed until at least Tuesday. Expect continued sunny skies and warm
temperatures. Temperatures cool somewhat on Tuesday as marine air starts moving in, associated with the arrival of the weakening disturbance and upper trough. Air mass will remain mostly stable and smoke dispersion poor to fair.</div>
