THE POTENTIAL IMPACT OF THIS EARLY-SEASON SNOW EVENT...HAVE ISSUED
THE ADVISORY TO COVER MOST AREAS DESPITE SOME NOT QUITE MEETING
FORECAST SNOW AMOUNT CRITERIA.

HAVE BEEN LEANING ON THE NAM12 IN THE SHORT TERM...THROUGH SOME OF
THE RAIN TOTALS FROM THIS MODEL LOOK OVERDONE LATER TODAY THROUGH
TONIGHT. ITS SOLUTION OF A 996 MILLIBAR SURFACE LOW PARKED OFF

.PREV DISCUSSION... /ISSUED 332 AM PST MON NOV 3 2008/
DISCUSSION...A ONE TWO PUNCH WILL MOVE INTO SOUTHWEST OREGON AND
NORTHERN CALIFORNIA TODAY. THE FIRST EVENT IS ALREADY BRINGING
RAIN TO SOUTHWEST OREGON AND NORTHERN CALIFORNIA WITH RAINFALL
AMOUNTS IN THE PAST 6 HOURS BETWEEN .30 AND .60 INCHES. 500MB
TEMPS OF -24C AND GREATER WILL REACH THE COAST LATE THIS AFTERNOON
AND TONIGHT WHICH COULD BRING ISOLATED THUNDERSHOWERS OVER THE
MARINE WATERS AND ADJACENT COAST.

CURRENT IR IMAGE SHOWS A LOW DEVELOPING NEAR 42 N AND 133 W. THIS
WILL BE THE SECOND PUNCH THAT WILL IMPACT THE CWA LATE THIS
AFTERNOON AND TONIGHT. BOTH THE NAM AND GFS BRING THIS LOW TO THE
COAST LATE THIS AFTERNOON...THEN MOVING THROUGH THE CWA OVERNIGHT
TONIGHT. SNOW LEVELS WILL LOWER TO 4000-4500 FEET OVERNIGHT
TONIGHT. WITH THE BULK OF THE MOISTURE EXPECTED TO BE CENTERED IN
SOUTHWEST OREGON AND WESTERN AND SOUTH SISKIYOU COUNTY...HAVE GONE
WITH A SNOW ADVISORY FOR CAZ 80 AND 82. THE ADVISORY IS
BORDERLINE...BUT THERE IS THE POTENTIAL FOR SOME LOCATIONS TO PICK
UP TO 8 INCHES TONIGHT ABOVE 4500 FEET. THE SISKIYOUS AND CASCADES
WILL GET THEIR FIRST SIGNIFICANT SNOW OF THE SEASON...BUT AMOUNTS
ARE EXPECTED TO REMAIN BELOW ADVISORY CRITERIA. HOWEVER IT IS
LIKELY THAT HWY 140 AND 62 AS WELL AS SISKIYOU SUMMIT WILL PICK UP
4 TO 7 INCHES TUESDAY NIGHT.

THE TROUGH AXIS WILL SHIFT EAST OF THE CWA TUESDAY WITH A COLD
MOIST WEST TO NORTHWEST FLOW ALOFT. SHOWERS TUESDAY WILL BE MOSTLY
CONFINED TO ALONG AND WEST OF THE CASCADES WITH SNOW LEVELS
HOVERING AROUND 400 FEET.

500MB HEIGHTS RISE AS THE TROUGH CONTINUES TO MOVE EAST TUESDAY
NIGHT. AT THE SURFACE...A WARM FRONT WILL APPROACH THE COAST
TOWARDS WEDNESDAY MORNING...THEN MOVE INLAND WEDNESDAY AFTERNOON.
IT IS QUESTIONABLE AS TO HOW MUCH AND THE EXTENT OF THE
PRECIPITATION. IT LOOKS LIKE MOST OF THE SIGNIFICANT QPF WILL BE
NORTH OF CAPE BLANCO AND OVER THE NORTHWEST PART OF THE CWA. THE
MODELS DO HINT AT MORE ALONG THE SOUTHWEST COAST...BUT THIS MAY BE
A BIT OVERDONE.

THE WARM FRONT ALONG WITH THE PRECIPITATION WILL LIFT NORTH OF
THE CWA WEDNESDAY NIGHT WITH MOST AREAS TURNING OUT DRY AND MILDER
THURSDAY. THE DRY AND MILD WEATHER WILL CONTINUE INTO
FRIDAY...THEN RAIN WILL RETURN SATURDAY AS A COLD FRONT APPROACHES
THE AREA.

&&

.AVIATION...CIGS WILL LOWER TO IFR THIS MORNING AND AFTERNOON.
CIGS AT THE COAST WILL BE AROUND 1500 FEET WITH SOME AREAS
LOWERING BELOW 1000 FEET. VISIBILITIES WILL OCCASIONALLY BE
RESTRICTED DUE TO A LOW CLOUD DECK AND PRECIPITATION. INLAND
LOCATIONS CIGS WILL START OUT AT MARGINAL MVFR THEN ARE EXPECTED
TO LOWER TO IFR THIS AFTERNOON INTO THIS EVENING. MTNS WILL BE
OBSCURED TODAY WITH VISIBILITIES OCCASIONALLY BEING REDUCED DUE TO
RAIN. WINDS WILL INCREASE LATE THIS MORNING AND AFTERNOON AS
ANOTHER DEVELOPING LOW PRESSURE REACHES THE COAST.
