<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</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 area Friday morning to afternoon. Expect moisture to increase during the day. Colder air
will move in with the front, and the following trough. Snow level will lower to 3000 ft by evening. 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 Saturday morning with a minor and transitory ridge moving in. Next front and trough will race in from the Pacific Saturday with moisture increasing again during the late afternoon to evening. Temperatures
will moderate some with the snow level rising to 4000 – 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>

<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 Friday, November 20, 2009.</div>
<div> ==================================================================</div>
<div> </div>
<div style="padding-left: 36pt; ">Avoid ignitions within 10 miles to the S through WNW of SSRAs. Care needed in selecting units as smoke will likely fumigate along the ground in wind prone areas. No additional restrictions necessary. </div>
