<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 continue to build over the state today and through the weekend bringing warmer and drier conditions. Air mass will stabilize during the night and morning hours but daytime heating in the interior will
bring a period of good mixing. Wind flow will remain generally light northerly. Expect mostly fair smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Ridge reaches its peak over the state on Sunday bringing the warmest temperatures. However, marine air will move in during the afternoon as a trough and minor front move in on Monday. Front will bring some light rain to mainly
the northern part of the state with a few lingering showers early Tuesday as the trough passes to the east. Air mass will be stable Sunday morning then destabilize during the day. Air mass will remain mostly unstable Monday and Tuesday under the influence
of the trough pattern and brisk westerly flow.</div>
