DISCUSSION...
A WAVE OF MAINLY LIGHT PRECIPITATION CONTINUES TO SAG SOUTHWARD ACROSS
INTERIOR CENTRAL CALIFORNIA THIS MORNING AS A SHORTWAVE TROUGH AND
DEVELOPING CLOSED LOW APPROACH THE WEST COAST. RAINFALL ACCUMULATIONS
RANGE FROM A FEW HUNDREDTHS TO A FEW TENTHS OF AN INCH...WHILE A
FEW INCHES OF SNOWFALL IS ESTIMATED IN THE HIGHER SIERRA ABOVE THE
7-8 THOUSAND FOOT SNOW LEVEL. SCATTERED SHOWERY PRECIPITATION IS
PROGGED TO CONTINUE TODAY AND LINGER THROUGH THURSDAY AS THE
TROUGH SWINGS INLAND AND THE UPPER LOW SLIDES SLOWLY SOUTH TOWARD
THE SOUTHERN CALIFORNIA COAST. EXPECT SIMILAR ADDITIONAL
PRECIPITATION ACCUMULATIONS DURING THE PERIOD WHILE SNOW LEVELS
REMAIN RELATIVELY HIGH IN THIS RATHER WARM STORM.

MODEL CONSENSUS REMAINS FAIRLY GOOD ON THE EVOLUTION OF THE
SYNOPTIC PATTERN AS THEY KICK THE LOW OUT TO THE EAST THROUGH THE
WEEKEND. JUST SLIGHT CHANCES OF SOME WRAP AROUND SHOWERS IN
OROGRAPHICALLY FAVORED AREAS AS THE LOW KICKS OUT. HIGH
TEMPERATURES CONTINUE TO RUN NEAR CLIMO THOUGH SOME COLDER AIR
BEHIND THE EXITING STORM WILL BRING SOME CHILLY OVERNIGHT LOWS AS
CLOUDS CLEAR OUT. A CHANCE FOR A MONO TYPE WIND EVENT IS MEANWHILE
EXPECTED BY THURSDAY EVENING AS THE LOW DROPS SOUTHWARD.

SHORTWAVE RIDGING BEHIND THE EXITING SYSTEM WILL BRING SOME SLIGHT
WARMING EARLY NEXT WEEK WHILE MOISTURE FROM THE PRECIPITATION
EVENT COULD SET THE STAGE FOR THE FIRST SIGNIFICANT FOG EVENT OF
THE SEASON.
