DISCUSSION:
THERE WILL BE ENOUGH INSTABILITY THIS AFTERNOON AND EVENING TO BRING
A RISK OF SHOWERS AND THUNDERSTORMS OVER THE MOUNTAINS. RAIN RATES
AND TOTALS WILL GENERALLY BE LIGHT, BUT ISOLATED HEAVIER SHOWERS AND
THUNDERSTORMS ARE POSSIBLE WITH LOCALIZED RATES UP TO AROUND 0.50
INCHES PER HOUR.
ANOTHER LOW PRESSURE SYSTEM WILL MOVE THROUGH THE AREA OVER THE
WEEKEND. COASTAL AREAS WILL LIKELY SEE SPOTS OF DRIZZLE OR LIGHT
RAIN, ESPECIALLY SATURDAY MORNING, AND SUNDAY. ANY ACCUMULATIONS
WILL BE VERY LIGHT AND UNDER 0.10 INCHES. OVER THE MOUNTAINS AND
INTERIOR AREAS, OFF AND ON AGAIN SHOWERS WILL BE COMMON, WITH
LOWERING SNOW LEVELS DOWN TO AROUND 5,500 FEET BY SUNDAY. RAIN AND
SNOW AMOUNTS WILL ALSO GENERALLY BE LIGHT, BUT THERE IS SOME
INSTABILITY THAT WILL LIKELY RESULT IN LOCALIZED HEAVIER SHOWERS OR
EVEN A THUNDERSTORM. AS A RESULT, SOME LOCALIZED MOUNTAIN LOCATIONS
COULD SEE UP TO 0.50 INCHES OF RAIN AND SNOW IN THE 2 TO 5 INCH
RANGE.
DRYING EXPECTED TO FOLLOW NEXT WEEK.
THE LAST ROUTINE ISSUANCE OF THIS PRODUCT FOR THIS RAINY SEASON WAS
ON APRIL 30. ROUTINE ISSUANCES WILL RESUME ON NOV 1. NON-ROUTINE
ISSUANCES OF THIS PRODUCT WILL OCCUR SHOULD WIDESPREAD PRECIPITATION
BE EXPECTED.
