..DISCUSSION FROM RNOFWFVEF
CLOUD COVER THINS THROUGH THE AFTERNOON WITH COOLER THAN AVERAGE
TEMPERATURES EXPECTED AND IMPROVED HUMIDITY RETENTION. ANOTHER
CHANCE FOR LIGHT RAIN WILL BE POSSIBLE FOR WESTERN PORTIONS OF THE
DISTRICT ON MONDAY, BUT NOTHING IMPACTFUL IS EXPECTED. BREEZY TO
GUSTY SOUTH AND SOUTHWEST WINDS BUILD ACROSS THE SIERRA NEVADA ON
TUESDAY AND SPREAD ACROSS THE REGION ON WEDNESDAY AS THE NEXT
TROUGH AND LOW PRESSURE BUILD INTO THE REGION. LIGHT RAIN AND
LIGHTER SNOW ARRIVE LATE TUESDAY FOR HIGHER ELEVATIONS AROUND THE
SIERRA, BUT RAIN CHANCES WONT BECOME WIDESPREAD UNTIL WEDNESDAY
AFTERNOON. RAIN RATES LOOK MODERATE AT BEST FOR MOST AREAS BUT GOOD
CHANCES FOR WETTING RAIN IS EXPECTED. RAIN CHANCES PEAK EARLY
THURSDAY WITH SHOWERS EXITING THE REGION ON FRIDAY. STORM CHANCES
WILL BE POSSIBLE WITHIN THIS SYSTEM BUT LOOK TO BE FEW AND FAR
BETWEEN
..DISCUSSION FROM LAXFWFSGX
TEMPERATURES GRADUALLY COOL THROUGH THURSDAY AS ONSHORE FLOW
RETURNS AND INCREASES. RELATIVE HUMIDITIES WILL ALSO INCREASE
THROUGH MID-WEEK. A STORM SYSTEM APPROACHES FROM THE NORTHWEST LATE
TUESDAY INTO WEDNESDAY. WIDESPREAD LIGHT TO MODERATE RAIN IS
EXPECTED WITH THE MOST LIKELY TIMEFRAME BEING LATE WEDNESDAY INTO
THURSDAY. THE CHANCE OF WETTING RAIN IS 90-100% FROM THE COAST TO
THE MOUNTAINS, 50-70% FOR THE HIGH DESERT, AND 5-10% FOR THE LOW
DESERTS, HIGHEST FOR NORTHWEST PORTIONS OF THE REGION. THERE IS A
WIDESPREAD 15 TO 25% CHANCE FOR THUNDERSTORMS FOR AREAS FROM THE
COASTS TO THE MOUNTAINS ON THURSDAY, WHICH COULD BRING LOCALLY
HIGHER RAIN RATES.
..DISCUSSION FROM PHXFWFPSR
LIGHT SHOWERS WILL CONTINUE TO BE FOCUSED OVER EASTERN DISTRICT
TERRAIN AREAS MONDAY THOUGH THE CHANCE FOR WETTING RAINFALL IS
QUITE LOW AT LESS THAN 20%. MINIMUM HUMIDITY LEVELS WILL ONLY FALL
INTO A 30-50% RANGE FOLLOWING GOOD TO EXCELLENT OVERNIGHT RECOVERY.
WINDS WILL OBTAIN MORE OF A LIGHT AND VARIABLE CHARACTER WITH A
TENDENCY FOR DIRECTIONS TO BECOME EASTERLY AND SOUTHERLY BY TUESDAY
WITH LIMITED AFTERNOON GUSTINESS.
