THAT COOL UPPER LEVEL TROUGH STILL LINGERS OFF THE WEST COAST AND WILL GIVE US A SLIGHT CHANCE OF THUNDERSTORMS AND SHOWERS IN THE MOUNTAINS THROUGH THURSDAY. IT THEN OPENS UP AND MOVES INLAND THURSDAY AFTERNOON INTO FRIDAY WITH A SHORTWAVE RIDGE DEVELOPING OVER THE WEST. THIS WILL GIVE US A DRY NORTHWEST FLOW AND MOSTLY CLEAR SKIES AND WARMING TEMPERATURES OVER THE WEEKEND. LATE MONDAY INTO TUESDAY THE SEEMLY ENDLESS NUMBER OF TROUGHS MOVING THROUGH THE PACIFIC NORTHWEST CONTINUES. THAT UPPER RIDGE SHIFTS EAST IN RESPONSE TO ANOTHER TROUGH WHICH WILL JUST BRUSH OUR AREA. THERE WILL BE ENOUGH INSTABILITY TO WARRANT A SLIGHT CHANCE OF THUNDERSTORMS ON TUESDAY AFTERNOON AND EVENING IN THE MONO COUNTY HIGH COUNTRY AND THE WHITE MOUNTAINS. DRY WEATHER ON WEDNESDAY THEN YET ANOTHER TROUGH TAPS OUR AREA ON THURSDAY.
