FOR THURSDAY INTO FRIDAY NIGHT, A LARGE LOW PRESSURE SYSTEM
CENTERED OFF THE WEST COAST WILL DRAW MOISTURE FROM THE REMNANTS
OF WEAKENING HURRICANE PRISCILLA NORTHWARD INTO THE AREA,
INCREASING CHANCES FOR SHOWERS AND THUNDERSTORMS. THE GREATER
CHANCES FOR HEAVIER RAINFALL ARE FROM THE MOUNTAINS OF SAN
BERNARDINO, RIVERSIDE, AND SAN DIEGO COUNTIES EASTWARD ACROSS THE
DESERTS INTO ARIZONA WITH DECREASING CHANCES TOWARD THE WEST.
HIGHER-RESOLUTION MODEL GUIDANCE SHOWS BANDS OF SHOWERS WITH A
SLIGHT CHANCE OF THUNDERSTORMS MOVING NORTHWESTWARD ACROSS THE
AREA ON THURSDAY MORNING WITH ADDITIONAL CHANCES FOR SHOWERS AND
THUNDERSTORMS DURING THE AFTERNOON MORE FOCUSED OVER THE MOUNTAINS
EASTWARD ACROSS THE DESERTS. CHANCES FOR SHOWERS AND THUNDERSTORMS
WILL CONTINUE AT TIMES THROUGH FRIDAY INTO FRIDAY EVENING. NBM
CHANCES FOR ONE INCH OR MORE OF RAINFALL IS AROUND 5 PERCENT FOR
THE MOUNTAINS. HOWEVER, THE HRRR DOES SHOW THE POTENTIAL FOR
6-HOURLY RAINFALL TO AROUND 1.5 INCH FOR PORTIONS OF THE MOUNTAINS
AND DESERTS FOR THURSDAY AFTERNOON.
