<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>
<div>SALEM FORESTRY WEATHER CENTER</div>
<div>OREGON DEPARTMENT OF FORESTRY</div>
<div> </div>
<div>ISSUED: Tuesday, June 8, 2010 2:30 PM Jim Little</div>
<div> </div>
<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div> WEDNESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">An upper level low pressure area will move to off the Washington coast Wednesday. This will give southwesterly flow aloft to the region. A Pacific weather system embedded in that southwesterly flow ushers in rain beginning
Tuesday evening and continuing throughout the day Wednesday. Amounts will range from about 1/10<font size="1"><sup>th</sup></font> of an inch near Medford to near 4/10ths of an inch in the northern coast range. Smoke dispersal conditions will be generally
fair.</div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">The upper low weakens – the remaining trough slowly moves east across the Pacific Northwest. Expect showers off and on during the day. Some subsidence on the back side of the trough will help end the showers later in the
day but also suppress mixing heights a bit. By Friday upper ridging develops in the eastern Pacific and most of the showers should be over. Transport winds will have a northerly component, perhaps offering burn opportunities that have not been present with
the persistent southwesterly or westerly pattern of the past several days. Saturday should see dry and warmer weather. The warmer afternoon surface temperatures should push mixing heights to above 5000 feet for good smoke dispersal conditions. </div>
