<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough and minor disturbance are rapidly moving toward the state this afternoon - ahead of schedule. This disturbance will increase the marine layer overnight and likely bring some light rain to the region beginning
tomorrow morning. Air mass will be mostly unstable, and with decent onshore flow, will make for good to excellent smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The trough from Friday’s disturbance will move through early Saturday but will be quickly followed by another disturbance and trough Saturday afternoon. This trough will bring more showers into the area and even cooler temperatures
as the snow level drops to near 6000 ft. Trough will move by to the east Sunday and Monday with the air mass drying and warming. Expect good mixing and smoke dispersion through the period.</div>
