.DISCUSSION...

AN UPPER LEVEL DISTURBANCE WILL MOVE THROUGH THE UPPER LEVEL RIDGE TODAY
WITH ISOLATED THUNDERSTORMS A POSSIBLY BY 1400 LOCAL TIME. IT SHOULD BE
MOSTLY CLEAR BEFORE NOON LOCAL WITH CLOUDS ON THE INCREASE AFTERWARD.
UPPER LEVEL WINDS ARE WEAK TODAY AND STORMS MAY FORM TO YOUR WEST AND
DRIFT OR PROPAGATE SLOWLY TO THE SOUTHEAST ALONG THE MOUNTAINS...WITH
THE BEST CHANCE FOR A STORM IN YOUR AREA LATE IN THE AFTERNOON TO EARLY
EVENING. SHOWERS AND THUNDER ARE MORE LIKELY AT HIGH ELEVATION SO IT IS
POSSIBLE THAT YOU WILL NOT EXPERIENCE A STORM TODAY AS THEY WILL HAVE A
HARD TIME MOVING OFF THE MOUNTAINS PROPER AND INTO THE SOUTHERN FOOTHILLS.
MOUNTAIN SHOWERS AND THUNDERSTORMS WILL PERSIST ON AN ISOLATED BASIS
THROUGH THE EVENING PERIOD BEFORE WAINING OVERNIGHT. THERE WILL BE A
DAILY CHANCE OF ISOLATED AFTERNOON OR EVENING SHOWERS AND THUNDERSTORMS
EACH AFTERNOON THROUGH THE EXTENDED PERIOD.
