LAST UPDATE: 8:11 AM PDT SEP 12, 2007

AN OVERALL CHANGE IN OUR WEATHER PATTERN IS UPON US, WITH A SHIFT TO A MORE LOW PRESSURE ORIENTED SENARIO. AN UPPER LOW IS CONTINUING TO MOVE TOWARDS THE WEST COAST AND WILL EFFECT OUR WEATHER STARTING ON THURSDAY INTO FRIDAY WITH A DROP IN TEMPERATURES OVER OUR ENTIRE AREA FOR BOTH INYO AND MONO COUNTIES. WINDS WILL PICK UP LATER TODAY, AHEAD OF THE APPROACHING LOW AND STAY WITH US FOR THE NEXT FEW DAYS. A DRY SOUTHWEST FLOW WILL DEVELOP AND THIS WILL KEEP THE EASTERN SIERRA'S SKIES MOSTLY CLEAR AND THUNDERSTORM FREE.

TODAY FOR BISHOP AND THE OWENS VALLEY: MOSTLY SUNNY SKIES WITH HIGH TEMPERATURES IN THE MID 90S. LOW TEMPERATURES IN THE MID 50S. AFTERNOON WINDS WILL BE FROM THE SOUTHWEST @ 10 - 15 MPH GUSTING TO 25 MPH.

TOMORROW FOR BISHOP AND THE OWENS VALLEY: MOSTLY CLEAR. HIGH TEMPERATURES AROUND 90. LOW TEMPERATURES IN THE LOWER 50S. AFTERNOON WINDS FROM THE SOUTH @ 10 - 20 WITH GUSTS TO 30.

TODAY FOR MAMMOTH AND THE MONO VALLEYS: MOSTLY SUNNY. HIGH TEMPERATURES AROUND 74 FOR THE MAIN LODGE AND THE LOW 80S FOR THE MONO VALLEYS. LOW TEMPERATURE RANGE 38 - 48. AFTERNOON WINDS FROM THE SOUTHWEST @ 10 - 15 WITH SOME GUSTS TO 30 MPH.

TOMORROW FOR THE MAMMOTH AND THE MONO VALLEYS: SUNNY SKIES BY MID DAY. HIGH TEMPERATURES AROUND 68 FOR THE MAIN LODGE AND THE UPPER 70S FOR THE MONO VALLEYS. LOW TEMPERATURE RANGE 37 - 47. AFTERNOON WINDS FROM THE SOUTH WIND @ 10 - 15 MPH GUSTING TO 35.

THE LOW WILL STALL OVER SOUTHWEST OREGON OVER THE WEEKEND, CONTINUING THE DRY SOUTHWEST FLOW. THIS WILL KEEP TEMPERATURES FROM RISING AND CONTINUE TO KEEP OUR SKIES CLEAR AND WITH NO THUNDERSTORM ACTION. BY MONDAY THAT UPPER LOW LIFTS TO THE EAST AND RIGHT NOW MODELS ARE SHOWING A DEEPER LOW MOVING IN ABOUT WEDNESDAY OF NEXT WEEK WITH ANOTHER SHOT OF COOL AIR FOR US. IF THIS PANS OUT (AND THERE IS STILL SOME UNCERTAINTY ABOUT THIS) WE COULD SEE OUR FIRST DUSTING OF SNOW IN THE UPPER ELEVATIONS BY END OF NEXT WEEK. EITHER WAY, HIGH COUNTRY TREKKERS SHOULD BE PREPARED FOR UNSETTLED WEATHER. STAY TUNED FOR UPDATES ON THIS.
