12Z NGM/ETA/GFS IN IN BITS AND PIECES.

A COLD FRONT IS NOW MOVING ONSHORE...BUT BECOMING PARALLEL TO THE
UPPER LEVEL FLOW AS IT DOES SO.  THEREFORE ITS FORWARD PROGRESS IS
SLOWING AND WAVES ARE DEVELOPING ALONG THE FRONT IN RESPONSE TO
UPPER LEVEL SHORT WAVES EMBEDDED IN STRONG SOUTHWEST FLOW ALOFT.
THE FIRST OF THESE WAVES WILL MOVE ONSHORE NEAR FLORENCE THIS
AFTERNOON.   IT WILL INDUCE A STRONG PRESSURE GRADIENT FROM CAPE
BLANCO SOUTH SO THE EXTENSION OF THE HIGH WIND WARNING LOOKS LIKE A
GOOD CALL.  THE GRADIENT OVER NORTHERN CALIFORNIA HAS ALSO TIGHTENED
AND WINDS IN THE WEED AREA HAVE ALREADY MET HIGH WIND WARNING
CRITERIA.

THE FRONT WILL MOVE INLAND DECISIVELY INLAND TONIGHT BUT ANOTHER
WAVE WILL DEVELOP OVER NORTHERN CALIFORNIA AS IT DOES SO...SLOWING
THE FRONT ONCE AGAIN.  HOWEVER THE GRADIENTS WILL RELAX SO THE STRONG
WINDS WILL END THIS EVENING.  THE FRONT WILL CLEAR TO THE SOUTH
AND EAST LATE MONDAY NIGHT OR TUESDAY MORNING...BUT THE OFFSHORE
UPPER TROUGH WILL SUPPORT SHOWER ACTIVITY UNTIL IT WEAKENS AND MOVES
INLAND TUESDAY EVENING.

A BREAK IN THE ACTION TUESDAY NIGHT WITH UPPER LEVEL RIDGING...BUT
A WARM FRONT PULLING UP AHEAD OF THE NEXT SYSTEM ON WEDNESDAY WILL
BRING ANOTHER ROUND OF WIND AND PRECIPITATION...BUT NOTHING LIKE
WHAT IS HAPPENING TODAY.  THE TRAILING COLD FRONT WILL MOVE ONSHORE
THURSDAY AND IT LOOKS LIKE IT WILL BE A SLOW MOVING SYSTEM WITH
WAVES DEVELOPING ALONG THE FRONT...SO ANOTHER ROUND OF SIGNIFICANT
PRECIPITATION LOOKS LIKELY.

SNOW LEVELS AT 3500 FEET WILL RISE TO 4500 FEET TODAY AND BACK DOWN
TO 3000 FEET TONIGHT.  FLOOD WATCH IS IN EFFECT.  AREAS OF URBAN AND
SMALL STREAM FLOODING WILL BE LIKELY...MAINLY ON THE WEST SIDE AND
ALSO HIGH PROBABILITY OF FLOODING IN THE COQUILLE BASIN AND LOWER
ROGUE RIVER.
