font-family:"Courier New"'>The upper level low moves to about 400 miles west of
San Francisco on Thursday. Upper flow over Oregon backs to southwesterly.
Warm air aloft keeps mixing heights suppressed for just fair smoke dispersal
conditions. On Friday the upper level low drops southward to off the
southern California coast. Maximum mixing heights should reach 4000 to
4500 feet for improving smoke dispersal conditions. Look for dry weather
under mostly sunny skies. Smoke dispersal conditions remain
marginal. On Saturday the upper low opens up and moves northeast as a
weak upper level trough. Smoke dispersal conditions will further improve
and the southerly transport winds of Friday will continue.</span><o:p></o:p></p>
