BRING PERIODIC RAIN THROUGH TONIGHT. COLDER AIR ALOFT WILL SPREAD
INTO THE REGION TONIGHT THROUGH WEDNESDAY...BRINGING A CHANCE FOR
SNOW ABOVE 3000 FEET WEDNESDAY MORNING. HIGH PRESSURE WILL BUILD

.DISCUSSION...VIGOROUS LOW OFFSHORE WAS MOVING NORTHEAST TOWARDS THE
OREGON COAST EARLY THIS MORNING. WINDS HAVE BEEN RAMPING UP OVER THE
COASTAL WATERS AND OVER COASTAL HEADLANDS IN RESPONSE TO THE
OCCLUDING LOW. STRONG JET AND ASSOCIATED SUBTROPICAL MOISTURE PLUME
WAS SLOWLY SAGGING SOUTHEASTWARD ACROSS THE AREA THROUGH THE NIGHT.
THE HEAVY RAIN THAT DROVE RIVERS TO NEAR MONITOR STAGE ON THE SMITH
RIVER IN DEL NORTE COUNTY...WILL CONTINUE TO SPREAD SOUTHEASTWARD
TODAY ACROSS HUMBOLDT AND MENDOCINO COUNTIES. EXPECT THE RAINFALL
INTENSITIES AND RATES TO DECREASE IN DEL NORTE COUNTY TODAY. STAGES
ON THE SMITH HAVE BEEN FALLING THROUGH THE NIGHT AND AS OF 4AM WAS
BELOW MONITOR STAGE AT DR FINE BRIDGE.  THE NEXT FOCUS OF CONCERN
WILL BE AREAS THAT HAVE ACTUALLY SEEE RAIN FOR THE LAST 24-36 HOURS.
MAD RIVER AT ARCATA AND EEL RIVER AT FERNBRIDGE ARE STILL FORECASTED
TO APPROACH OR SLIGHTLY EXCEED MONITOR STAGES TONIGHT/EARLY WED. A
RIVER STATEMENT WILL LIKELY BE ISSUED LATER THIS MORNING. BEST RAIN
RATES STILL LOOK TO BE ACROSS THE EEL BASIN. RAIN HAS BEEN REALLY
SLOW TO MATERIALIZE ACROSS SOUTHERN MENDOCINO COUNTY. AS OF 5
AM...UKIAH MUNI ASOS FINALLY REPORTED 0.01 INCH OF RAIN. THATS
ALMOST AS MUCH AS 6-12 HRS SLOWER THAN WHAT MODEL FORECASTS
INDICATED YESTERDAY. THUS THE FLOOD WATCH FOR THE NAVARRO RIVER AT
NAVARRO WAS CANCELLED.

SNOW LEVELS WILL LOWER LATE TONIGHT AND WEDNESDAY MORNING...DOWN
TO 3500 TO 4000 FEET. GFS AND ETA WERE IN GOOD AGREEMENT ON BRINGING
COLDER AIR...STEEPER LAPSE RATES AND BLUSTERY NORTHWESTERLY FLOW
INTO THE FORECAST AREA TONIGHT/EARLY WEDNESDAY. PRECIP AMOUNTS WILL
PROBABLY EASE UP IN THE COLDER AIR MASS. PRECIP ESTIMATES STILL
WARRANT A SNOW ADVISORY FROM ABOUT 10 PM TUE TO 10 AM WED ABOVE
3500 TO 4000 FEET.

RIDGE ALOFT AND OFFSHORE FLOW DEVELOPS WED NIGHT AND THURSDAY
AND WE SHOULD SEE A 24-48 HOUR WINDOW OF DRY...BUT COLD WEAX.
SOLUTIONS INDICATE ANOTHER SERIES OF RELATIVELY WEAK FRONTAL SYSTEMS
MOVING TOWARDS THE COAST FRIDAY THROUGH MONDAY. WITH 500MB HGTS
RISING THROUGH SAT OR SUN...BEST PRECIP CHANCES SHOULD BE NORTH
COAST ZONES 1 AND 3. TIMING OF EACH EVENT IS STILL UNCERTAIN. AT
THIS TIME WILL JUST KEEP A BROAD BRUSH CHANCE OR SLIGHT CHANCE
OF RAIN IN EVERY ZONE EVERY DAY FRI THROUGH MON. DJB
