CLEAR OVER THE DISTRICT THIS AFTERNOON. TEMPERATURES WERE CLIMBING
INTO THE UPPER 70S TO LOWER 80S BY 3PM OVER THE LOWER ELEVATIONS
OF THE CENTRAL VALLEY AND KERN COUNTY DESERTS. ALTHOUGH
TEMPERATURES WILL BEGIN TO COOL AS THE UPPER RIDGE WEAKENS...READINGS
WILL REMAIN MILD THROUGH WED WITH DRY WEATHER PERSISTING.

A MAJOR CHANGE IN THE WEATHER PATTERN WILL TAKE PLACE ONCE AGAIN
DURING THE END OF THE WEEK AS A DEEPENING TROUGH OF LOW PRESSURE MOVES
SOUTHEAST OUT OF THE GULF OF ALASKA AND BECOMES POSITIONED OVER
THE WEST COAST THU AND FRI. THIS SYSTEM WILL INCREASE THE
PROBABILITY OF PRECIP OVER THE DISTRICT WED NIGHT...ESPECIALLY
NORTHERN PORTIONS OF THE SIERRA NEVADA ...BECOMING LIKELY OVER
MUCH OF THE AREA BY THU AFTERNOON. MUCH COLDER AIR ASSOCIATED WITH
THIS SYSTEM WILL LOWER SNOW LEVELS TO AROUND 2500 FEET IN THE
NORTH TO 3500 FEET IN THE SOUTH THU NIGHT/FRI MORNING. SNOW IS
EXPECTED INTO THE HIGHER SIERRA NEVADA FOOTHILL REGIONS WITH A
CHANCE OF SNOW OCCURRING ON THE GRAPEVINE IN THE SOUTH BY FRI.

MODELS START DROPPING ANOTHER TROUGH OUT OF THE GULF OF ALASKA
LATE SUNDAY AND MONDAY WITH A RENEWED CHANCE OF PRECIP ACROSS
MAINLY NORTHERN PORTIONS OF THE DISTRICT MONDAY. MODELS ARE IN
FAIRLY GOOD AGREEMENT IN RAPIDLY SHIFTING THIS SYSTEM EAST WITH
RIDGING OVER THE WEST COAST AND RETURN TO DRY WEATHER TUE.
