<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">Minor upper level ridge has built over the region this afternoon following the cold front that passed through yesterday. This ridge will slip to the east tonight as a warm front approaches from the west. The warm front will
spread some clouds over the area overnight and tomorrow but moisture will stay to the northwest. This pattern is very similar to the one experienced Monday and Tuesday. The front will stall and leave the region under breezy conditions tomorrow. After a stable
early morning, the combination of warming temperatures and increasing wind will improve smoke dispersion during the afternoon.</div>
<div> </div>
<div> OUTLOOK (FRIDAY - SUNDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Warm front moves by to the north by Friday with the cold front and trough approaching Friday afternoon. Moisture will be on the increase while the winds start to slacken. Cold front moves through Friday evening with cold
air following and lowering the snow level to the valley floors Friday night. Upper level trough moves through early Saturday morning. Another front and trough move in later Saturday with the trough passing through Sunday morning with a ridge following closely
behind. Expect good mixing and smoke dispersion through the period.</div>
