LIGHTNING HAS BEEN DETECTED IN THE CONVECTIVE ELEMENTS ASSOCIATED
WITH THE FIRST IN A SERIES OF STORMS OVER THE NORTH PACIFIC.

BEGINNING LATE TONIGHT AND CONTINUING THROUGH THE WORKWEEK. THESE
SYSTEMS WILL MOVE INTO THE WESTERN U.S. AS THE JET STREAM BECOMES
ESTABLISHED AT A LOWER LATITUDE OVER THE NORTH PAC WITH ENOUGH
ENERGY TO UNDERCUT THE HIGH-AMPLITUDE RIDGE CURRENTLY EXTENDING
FROM THE SOUTHERN ROCKIES TO THE ARCTIC CIRCLE. THIS PATTERN IS
MORE COMMON DURING EL NINO WINTERS THAN NON EL NINO WINTERS.

THE FIRST OF THESE WAVES WILL MOVE THROUGH SOCAL FROM THE WSW
LATE TONIGHT INTO EARLY TUE. DUE TO THE LOW LATITUDE OF THIS
WAVE...IT WILL BRING LITTLE IN THE WAY OF ADDITIONAL COLD AIR
INTO THE REGION SO TEMPS WILL NOT CHANGE MUCH FOR MON. THIS
SYSTEM WILL BRING MOSTLY LIGHT PRECIP TO THE REGION...WITH SNOW
LEVELS AT ABOUT 6000 FT. EXPECT ABOUT 0.2 TO 0.5 INCH OF PRECIP
AT LOW ELEVATIONS WEST OF THE MTNS WITH LOCALLY GREATER AMOUNTS
ON COASTAL MTN SLOPES...AND 1-3 INCHES OF SNOW IN THE MTNS ABOVE
6000 FT.

RAINFALL WITH RATES AND AMOUNTS CAPABLE OF MEETING OR EXCEEDING
THRESHOLDS THAT COULD PRODUCE MUD SLIDES AND/OR DEBRIS FLOWS
MAINLY ON STEEP...UNSTABLE TERRAIN...AND IN RECENTLY BURNED AREAS.
ADDITIONAL PRECIP AMOUNTS WITH THIS SYSTEM COULD RANGE BETWEEN 0.5
AND 1 INCH OVER LOWER TERRAIN WEST OF THE MTNS AND BETWEEN 1 AND 2
INCHES ALONG THE COASTAL SLOPES. ABOUT A FOOT OF SNOW WILL BE
POSSIBLE IN THE MTNS ABOVE 5500 FT.

A THIRD WAVE WILL MOVE IN FROM THE NW WED AFTERNOON...WITH PERIODS
OF RAIN LINGERING INTO FRI AFTERNOON AS WEAKER IMPULSES FOLLOW THE
LEADING WAVE IN NW FLOW ALOFT. AS COLDER AIR FILTERS IN FROM THE
NORTH...TEMPERATURES WILL DECREASE AND SNOW LEVELS COULD LOWER TO
BETWEEN 4500 AND 5000 FT BY THU MORNING. WEST NORTHWEST WINDS WILL
ALSO INCREASE WITH THIS SYSTEM...AND WIND GUSTS OF 45 TO 55 MPH
WILL BE POSSIBLE IN THE MTNS AND DESERTS ON THU. PRELIMINARY
PRECIP ESTIMATES WITH THIS SYSTEM ARE FOR BETWEEN 0.75 AND 1.25
INCHES WEST OF THE MTNS WITH LOCALLY HIGHER AMOUNTS ALONG THE
COASTAL SLOPES. 8 TO 12 INCHES OF ADDITIONAL SNOW WILL BE POSSIBLE IN
THE MTNS ABOVE 4500 FT.
