<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> ** Stable Pattern – Poor Smoke Dispersal Conditions through Mid-Week **</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level heights hold strong in spite of a short wave moving into British Columbia on Monday. The atmosphere will remain very stable for poor smoke dispersal conditions except for possible brief marginal conditions mid
afternoon. Mixing heights will remain low. Surface pressure gradients flat for light winds. Except for some morning fog in the valleys hazy fall sunshine will rule. </div>
<div> </div>
<div> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper ridge builds on Tuesday and surface high pressure increases over the region. Generally sunny and pleasant weather will continue with light winds and poor smoke dispersal conditions. Wednesday will be a near repeat
of Tuesday with very low mixing heights although winds aloft will increase a bit from the southwest. Real improvement will not occur until at least Thursday when smoke dispersal conditions will be fair with an upper trough approaching. This will cool temperatures
aloft to help destabilize the atmosphere a bit. In addition transport winds will be stronger from the south by Thursday. </div>
