PROVIDED BY DENNIS MATTINSON
EASTERN SIERRA WEATHER FORECASTER
KSRW 92.5 / 96.5 FM AND TV-33

THURSDAY, 03-SEP-09, MORNING REPORT
MID AND UPPER LEVEL MOISTURE COMBINED WITH THE SMOKE FROM THE SOCAL WILDFIRES HAS CREATED WHAT WE CALL A "DIRTY" SKY, WITH REDUCED VISIBILITIES IN VARIOUS AREAS OF THE OWENS VALLEY. WITH THAT MOISTURE AND SOME AFTERNOON HEATING, POSSIBLE CONVECTION OVER THE HIGH TERRAIN WILL EXIST FOR THE NEXT FEW DAYS. A COOLING TREND IS EXPECTED OVER THE WEEKEND AND INTO THE EARLY PART OF NEXT WEEK AS A BROAD UPPER TROUGH LUMBERS SLOWLY ACROSS THE PACIFIC NORTHWEST. WITH THIS WE CAN EXPECT MOSTLY CLEAR SKIES THROUGH ABOUT TUESDAY.
