<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low is in the eastern Pacific with a high pressure ridge to the east of the state. The low will continue to bring disturbances toward the region Friday with a chance of afternoon showers or thundershowers. Air
mass will remain mostly unstable under seasonally warm, southerly flow aloft. Expect mostly good smoke dispersion.</div>
<div><font face="Consolas, monospace"> </font></div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Weather pattern changes little on Saturday from Friday’s pattern. A few showers are possible over the coastal region but unlikely anywhere else. Upper level low moves closer to the state Sunday with increasing clouds Sunday
and the chance of moisture Sunday evening. Upper level low will continue to move in Monday with more moisture over the region through Monday. Air mass stabilizes on Saturday, then destabilizes Sunday afternoon and through Monday.</div>
