<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>

<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low off the northern California coast is lifting a warm front into the region this afternoon. Moisture has started over the southern part of the state and will slowly move northward this evening and into early
tomorrow. Low level cold air will be slow to retreat with likely a period of light snow and/or freezing rain in the interior valleys. Eventually, the snow level will rise to near 4000 ft Saturday afternoon. Air mass will destabilize first down south then
slowly scour to the north. Expect continued stable conditions and poor smoke dispersion through most of Saturday over the northern half of the region.</div>
<div> </div>
<div> OUTLOOK (SUNDAY - TUESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper trough to the south will gradually combine with the cold trough to the north bringing more showers on Sunday. Snow level will lower to 2000 – 3000 ft. Most lowland areas will scour out of the cold air except for
maybe the Columbia Gorge. Minor ridge builds in briefly Monday but this will quickly be overrun by the next frontal system coming in from the west. Look for increasing rain and wind Monday afternoon with the snow level lifting to 4000 – 5000 ft. Moist and
blustery conditions continue into Tuesday under strong SW flow aloft. Expect generally good mixing and smoke dispersion through the period. Some stabilization will occur Monday under the ridge but it will be brief.</div>
