.24 HOUR PRECIPITATION TOTALS (ENDING FEB 10 AT 400 AM PST)...

STRONG HIGH PRESSURE ALOFT LED TO ANOTHER DRY AND WARM DAY ACROSS
THE REGION.


.METEOROLOGICAL CONDITIONS (SHORT TERM: WED AM - SAT AM)...

A COUPLE WEAK BOUNDARIES WILL AFFECT THE FAR NORTH COAST FROM MAINLY
CAPE MENDOCINO NORTHWARD AND THEN SHIFT OVER THE UPPER KLAMATH RIVER
BASIN ON THURSDAY INTO FRIDAY. WITH THE UPR RIDGE REMAINING THE
DOMINANT FEATURE ALONG THE WEST COAST AND THE INTERIOR...THESE
SYSTEMS WILL BRING ONLY LIGHT PRECIP TO THESE AREAS.


.METEOROLOGICAL CONDITIONS (LONG TERM: SAT AM - TUE AM)...

LOOKING FOR A MAINLY QUIET STRETCH OF WEATHER IN THE LONG TERM.
COULD SEE A COUPLE SHOWERS IN FAR NE NV SAT MORNING AS A SHORTWAVE
PASSES BY JUST TO THE NORTH FROM ERN OREGON INTO WRN ID.  OTHERWISE,
MAIN FOCUS WILL BE LIGHT WARM ADVECTION PRECIP ACROSS MAINLY FAR NW
CA AND THE UPPER KLAMATH BASIN SAT EVENING THROUGH SUN EVENING.
FREEZING LEVELS 8000-10000 FT EXPECTED.  DRY CONDITIONS ARE EXPECTED
AGAIN BY LATER SUN NIGHT.


.HYDROLOGICAL CONDITIONS...

WITH WARM DRY CONDITIONS MOST RIVERS ARE RECEDING.  IN HIGH
ELEVATION WATERSHEDS SOME MINOR SNOWMELT OF LOW ELEVATION SNOW IS
CAUSING SOME SMALL RISES ON STREAMS AND RIVERS.

ALL STAGES ACROSS CALIFORNIA AND NEVADA ARE EXPECTED TO REMAIN WELL

HYDROMETEOROLOGICAL DISCUSSION
NATIONAL WEATHER SERVICE / CALIFORNIA NEVADA RFC / SACRAMENTO CA

...MOSTLY DRY THROUGH MIDWEEK...
...WEAK SYSTEM TO MOVE THROUGH THE NORTH ON FRIDAY...


.24 HOUR PRECIPITATION TOTALS (ENDING FEB 9 AT 400 AM PST)...

STRONG HIGH PRESSURE ALOFT PROVIDED DRY CONDITIONS AND ABOVE-AVERAGE
TEMPERATURES DURING THIS PERIOD.


.METEOROLOGICAL CONDITIONS (SHORT TERM: TUE AM - FRI AM)...

RIDGING REMAINS IN PLACE THIS MORNING...THOUGH IS BEING NUDGED
SLIGHTLY EASTWARD OVER TIME. THE UPPER JET CONTINUES TO BE DIRECTED
NORTHWARD INTO THE BRITISH COLUMBIA COASTLINE...KEEPING THE STORM
TRACK WELL TO THE NORTH OF THE AREA. THIS PATTERN WILL CONTINUE
THROUGH MID WEEK...THOUGH THE RIDGE WILL SLOWLY TAKE AN EASTWARD
JAUNT. THIS WILL ALLOW A SMALL BIT OF MOISTURE TO PUSH INLAND ON THE
BACK SIDE OF THE RIDGE...AND SOME LIGHT SHOWERS ARE POSSIBLE OVER
THE UPPER KLAMATH AND SMITH BASINS ON THURSDAY.

BY LATE THURSDAY...THE UPPER JET WILL DRAW A STEADY MOISTURE PLUME
TOWARDS THE NORTH COAST OF CA...INITIALLY WITH 1.3" AMOUNTS AT ITS
CORE...THOUGH IT ERODES QUICKLY. THIS MOISTURE...COMBINED WITH A
WEAK S/WV...WILL BRING LIGHT PRECIP TO THE NORTH COAST AS EARLY AS
SUNRISE FRIDAY.

.METEOROLOGICAL CONDITIONS (LONG TERM: FRI AM - MON AM)...

A COUPLE OF WEAK SYSTEMS ARE EXPECTED TO IMPACT THE NRN PORTION OF
THE REGION DURING THE PERIOD.  A COLD FRONT IS EXPECTED TO MOVE
ACROSS THE NORTH COAST ON FRI ACCOMPANIED BY A MOISTURE PLUME WITH
PW VALUES UP TO AROUND 1.1".  OVERALL ONSHORE FLOW AND DYNAMICS
ALOFT ARE FAIRLY WEAK, AND AMOUNTS ACROSS NRN CA AND SRN OREGON ARE
EXPECTED TO BE LIGHT.  A FEW LIGHT SHOWERS COULD BRUSH FAR NRN NV ON
SAT AS WELL AS THE SYSTEM PUSHES EAST.  EXPECT FREEZING LEVELS TO
START OFF AROUND 9000-10,000 FT AND LOWER TO 6000-8000 FT.

EXPECT SOME VERY LIGHT WARM ADVECTION PRECIP MAINLY IN THE UPPER
KLAMATH AND SMITH BASINS SAT NIGHT INTO SUN.  EXPECT FREEZING LEVELS
TO START OFF 6500-7500 FT AND RISE TO 9000-11,000 FT.


.HYDROLOGICAL CONDITIONS...

WITH WARM DRY CONDITIONS MOST RIVERS ARE RECEDING.  IN HIGH
ELEVATION WATERSHEDS SOME MINOR SNOWMELT OF LOW ELEVATION SNOW IS
CAUSING SOME SMALL RISES ON STREAMS AND RIVERS.

ALL STAGES ACROSS CALIFORNIA AND NEVADA ARE EXPECTED TO REMAIN WELL
BELOW MONITOR LEVELS THROUGH THE WEEK.
