<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge will remain in place through Saturday with the axis of the ridge near the Oregon/Idaho border. Expect continued summer-like weather. Air mass will remain stable except for brief afternoon instability inland
due to daytime heating. Like the last couple of days, thunderstorm buildups will continue in the afternoon to evening. Wind flow will remain weak and favor generally a NW flow. Smoke dispersion will remain poor to fair.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge starts weakening on Sunday as a trough moves down from the north and an upper low approaches from the southwest. However, expect continued warm and dry conditions. Thundershower threat will continue but
diminish somewhat. Eventually the upper level low in the eastern Pacific and to the southwest of the state will move close enough to bring increased clouds and maybe some moisture over the region on Tuesday. Wind flow will remain light and mostly northerly
Sunday and Monday. As the low approaches Tuesday, wind flow appears it will turn lightly offshore. Smoke dispersion will remain poor to fair.</div>
