CENTRAL OREGON ZONES 624 AND 625</FONT></DIV>
<DIV><FONT face="Courier New"></FONT> </DIV>
<DIV><FONT face="Courier New" size=2>A cool upper trough and associated surface
cold front will push through the region on Tuesday. The cooler air aloft
will keep the atmosphere unstable for high mixing heights and good smoke
dispersal. Rainfall will be fairly light but most areas should see
measurable precipitation.</FONT></DIV>
<DIV><FONT face="Courier New"></FONT> </DIV>
<DIV><FONT face="Courier New" size=2> OUTLOOK (WEDNESDAY -
FRIDAY):</FONT></DIV>
<DIV><FONT face="Courier New"></FONT> </DIV>
<DIV><FONT face="Courier New" size=2>An area of higher pressure aloft Tuesday
night will give way to an approaching cold front Wednesday night and early
Thursday. This will lose strength as it moves through, but should also
produce precipitation most areas. By Friday higher pressure will build in
and the atmosphere should begin to stabilize leading to less favorable smoke
dispersal conditions. </FONT></DIV>
