<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Thursday, June 25, 2009 2:30 PM Nick Yonker</div>
<div> </div>
<div>****Due to the lack of burning this will be the last forecast and instruction for the spring burning season. In addition, the smoke management office will switch from 7-day-a-week operations to Monday through Friday, 0630 – 1700. If you plan to burn
while we’re not writing forecasts and instructions, please call us at 503-945-7401 to coordinate. We will resume regular written forecasts in the fall when burning increases again.****</div>
<div> </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 trough will move through overnight bringing continued cloud cover and a chance of some light showers west of the Cascades. Upper level ridge will start building into the state on Friday with clouds dissipating
and giving way to afternoon sunshine. Air mass will generally remain unstable except for some night and early morning stability. Wind flow will be mostly NW to N as surface high pressure builds in. Wind speeds will be mostly light and lead to fair to good
smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper ridge continues building in over the state early Saturday before shifting eastward by the next trough in the eastern Pacific. Saturday will be the warmest day of the period with inland locations getting into the 80s
and 90s. Next trough will probably initiate a late Saturday marine push and bring low clouds into the inland valleys on Sunday. The trough will remain over the state through Monday keeping low clouds over the region during the night and morning hours but
breaking up some during the day. Smoke dispersion will be fair on Saturday, and then improve Sunday and Monday.</div>
