BISHOP BROKE THE ALL TIME HIGH YESTERDAY WITH A TEMPERATURE OF 99 DEGREES. I EXPECT COOLER TEMPERATURES TODAY THEN EVEN COOLER WEDNESDAY AS THE RIDGE OFF THE WEST COAST BREAKS DOWN IN RESPONSE TO A LARGE TROUGH MOVING INTO THE PACIFIC NORTHWEST. TEMPS COULD DROP AS MUCH AS 20 TO 30 DEGREES IN SOME AREAS FROM TODAY INTO THURSDAY. PRESSURE GRADIENTS WILL ALSO TIGHTEN CREATING WINDY CONDITIONS IN BOTH THE HIGH COUNTRY AND THE VALLEYS. THE WINDS WILL BE WITH US THIS AFTERNOON INTO AT LEAST WEDNESDAY. WE HAVE BOTH A RED FLAG WARNING FOR FIRE DANGER FROM 1 PM TO 9 PM TODAY ALONG WITH A HIGH WIND WARNING FROM 3PM TO 6 AM TOMORROW MORNING.
