<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div style="padding-left: 36pt; ">Warm front has pushed off to the northeast with the region in the warm sector of the frontal system. Cold front will swing into the region Friday morning to afternoon. Expect moisture to increase during the morning. Colder
air will move in with the front, and the following trough. Snow level will lower to the valley floors during the day. Air mass will remain mostly unstable and with decent wind flow, will make for excellent smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Trough exits to the east by Saturday morning with a minor and transitory ridge moving in. Next front and trough will race in from the Pacific Saturday with the chance of moisture increasing again during the late afternoon
to evening. Temperatures will moderate some with the snow level rising to 5000 ft by Sunday morning. A ridge will rebuild again late Sunday and Monday, but a warm front will ride through the ridge increasing clouds and the chance of moisture. Overall, expect
a very progressive weather pattern, keeping the air mass mostly unstable and dispersion good to excellent.</div>
