<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div> TUESDAY</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">An upper level low drops in from the northwest during the day Tuesday. Skies will be partly to mostly cloudy with scattered showers. Relatively cool air aloft will destabilize the atmosphere and help push maximum mixing heights
to above 5000 feet. This will give generally good smoke dispersal conditions to the region. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY-FRIDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low moves southeast into southern Idaho on Wednesday. Cooler daytime temperatures will limit maximum mixing heights a bit but smoke dispersal conditions should be at least fair to good most areas. There will still
be enough moisture for some scattered showers. By Thursday the upper level low will move east northeast into south-central Canada but some troughiness will hold back across the Pacific Northwest. Friday looks dry but partly to mostly cloudy. Mixing heights
both Thursday and Friday should be quite high yielding generally good smoke dispersal conditions. </div>

<div>3. BURNING INSTRUCTIONS FOR NORTHEAST OREGON ZONES 630-638</div>
<div> The following considerations should be adhered to in addition to</div>
<div> the requirements of the Oregon Smoke Management Plan. These</div>
<div> Instructions are valid for burning conducted on Tuesday, June 15, 2010.</div>
<div> ==================================================================</div>
<div> </div>
<div style="padding-left: 36pt; ">Zone 630 and 632:</div>
<div style="padding-left: 36pt; ">Avoid ignitions within 12 miles to the NW through N of SSRAs. For units that will smolder significantly through the night avoid burning within at least 20 miles to the WNW through N in or near drainages leading to SSRAs.
Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. </div>
<div style="padding-left: 36pt; "> </div>
