<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; ">Cold front moved by to the east this morning and will give way to a fairly flat upper level ridge tomorrow. Air mass will slowly stabilize overnight as skies clear. Some patchy fog is likely in the inland valleys Sunday morning.
Surface high pressure will build to the north and turn wind flow offshore. This should make for some decent burn opportunities in the Coast Range. Smoke dispersion, however, will be mostly poor to fair.</div>
<div> </div>
<div> OUTLOOK (MONDAY - WEDNESDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper ridge will remain in place Monday and Tuesday keeping the air mass stable and smoke dispersion poor. Expect some morning fog in the valleys with clearing skies during the afternoon. A minor front will bring increasing
clouds and a chance of rain to mainly the northern part of the region Wednesday afternoon. Air mass will remain stable but increasing SW’erly flow will improve smoke dispersion then.</div>
