<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 move off to the east tonight giving way to a cold front that will move through the region on Saturday. The front will provide a chance of some light rain, but overall, moisture amounts will be quite
limited. Cooler air follows the front but since the trough is not too deep, snow levels will not get as low as earlier in the week. Air mass briefly destabilizes tomorrow afternoon as the trough passes, providing decent smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge rebuilds rather quickly on Sunday with the air mass stabilizing through the day. Upper ridge will remain over the state for the rest of the period further stabilizing the air mass. Expect mostly sunny skies.</div>
<div> </div>
