SNOW...EXPECTED TODAY AS A COLD FRONT MOVES ACROSS THE REGION. COLD
AND UNSTABLE AIR AND ANOTHER WEAK DISTURBANCE WILL MAINTAIN A CHANCE
OF PRECIPITATION THROUGH THE WEEKEND.
&&

.DISCUSSION...S TO SE WINDS PREVAIL THIS MORNING AS A COLD FRONT
APPROACHES THE COAST. THE TIGHTENING GRADIENT IS RESULTING IN GUSTY
WINDS ALONG THE COAST AND OVER THE HIGHER TERRAIN OF THE INTERIOR.
GUSTS TO 40 TO 60 MPH ALREADY REPORTED IN HUMBOLDT/DEL NORTE
COUNTIES EXPECTED TO CONTINUE THROUGH SUNRISE BEFORE WEAKENING. WV
IMAGERY SHOWS JET MAX ROTATING AROUND BASE OF THE TROUGH AROUND
38N/130W AND RAIN CHANCES WILL INCREASE THIS MORNING AS THE TROUGH
APPROACHES THE COAST. EXPECT A FEW HOURS OF MDT PRECIP THIS
MORNING AS THE FRONT PUSHES INLAND WITH WIDESPREAD RAINFALL TOTALS
OF 1 TO 2 INCHES. THE TROUGH AXIS MOVES ONSHORE EARLY THIS AFTERNOON
WITH COOLING MID LEVELS AND STEEPENING LAPSE RATES RESULTING IN
INSTABILITY SHOWERS WITH THE POSSIBILITY OF SMALL HAIL ALONG THE
REDWOOD COAST. NSSL BRIGHT BAND ANALYSIS INDICATES SNOW LEVELS
AROUND 5500 FT ACROSS DEL NORTE COUNTY THIS MORNING. SNOW LEVELS
WILL LOWER THROUGH THE DAY AS COLD AIR FILTERS INTO THE REGION
BOTTOMING OUT AROUND 2500 FT LATE TONIGHT. ALTHOUGH THE BEST
MOISTURE REMAINS AHEAD OF THE COLDEST AIR...EXPECT SNOW
ACCUMULATIONS OF 3 TO 5 INCHES ABOVE 3500 FT ACROSS EASTERN TRINITY
COUNTY BY THIS EVENING WITH UP TO 2 INCHES ABOVE 3000 FT IN DEL
NORTE/HUMBOLDT AND WESTERN TRINITY COUNTIES. INSTABILITY SHOWERS

SHORT-WAVES MOVING OVER THE TOP OF THE RIDGE...WHICH MAY PRODUCE
LIGHT RAIN ACROSS THE NORTH COAST REGION FROM TIME TO TIME. THE GFS
AND ECWMF MODELS WERE OUT OF SYNC ON A FRONTAL SYSTEM EXPECTED

.MARINE...MODELS HAVE PULLED BACK ON THE EXTENT OF THE WINDS THIS
MORNING...LEAVING CONFINED WINDOWS OF GALE CONDITIONS. WITH THE S
FLOW AHEAD OF THE FRONT THE WINDY PLACE WILL BE AROUND CAPE
MENDOCINO AND JUST ON THE LEE SIDE. THIS HAS BEEN SHOWING WELL WITH
BUOY 22...WHERE AS OF 3 AM SUS WINDS WERE 34 GUSTING TO 42. AS THE
FRONT APPROACHES THE PRES GRAD ABOUT IT WILL ALLOW FOR A SLACKING OF
THE WINDS. THIS SHOULD BE SEEN AT THE BUOYS AROUND SUNRISE. THERE
WILL BE A BRIEF PULSE OF SUB GALE WINDS BEHIND THE FRONT BEFORE
PULLING BACK TO MODERATE WINDS. SEAS WILL LAG IN DECAY BEHIND THE
WINDS...BUT WILL BE OUT OF HAZ SEAS WARNING LEVEL BY AFTERNOON. MANY
OF THE WARNINGS OUT FOR THE WATERS WERE SCALED BACK DUE AS A RESULT
OF WINDS NOT BEING AS WIDE SPREAD. THE FRONT WILL CONTINUE TO WEAKEN
AS THE PARENT LOW MOVES ACROSS SRN BRITISH COLUMBIA TODAY AND WEAK
HIGH PRES PUSHES IT TO THE S. AFTER A POST FRONTAL TROUGH THAT WILL
CROSS THE WATERS OVER THE WEEKEND...HIGH PRES WILL BUILD ALLOWING
FOR EASING WINDS. SWELL WILL REMAIN SOMEWHAT ELEVATED FOR THE NEXT
SEVERAL DAYS. BFG

.AVIATION...RAIN HAS BEGUN AT CEC THIS MORNING AND WILL BE INTO ACV
SHORTLY. RAIN WILL PLAGUE THE COASTAL AIRPORTS THROUGH MUCH OF THE
DAY...TURNING TO SHOWERS IN THE AFTERNOON. WHILE NO VSBY
RESTRICTIONS HAVE DEVELOPED YET...THIS WILL WARRANT WATCHING. THAT
SAID...THE LOWERING CEILINGS WILL KEEP THE DAY IFR FOR THE COASTAL
REGION. WINDS WILL REMAIN A CONCERN ALONG WITH MID LEVEL WIND SHEAR
OUT AHEAD OF THE FRONT. 850MB FORECAST WINDS ARE SHOWING AS HIGH AS
60 KTS AHEAD OF THE FRONT WHILE SFC WINDS WILL BE IN THE 15 TO 25 KT
RANGE. WINDS WILL DIMINISH THROUGH THE COLUMN IN THE WAKE OF THE
FRONT. UKI WILL ALSO BE IFR FOR THE BETTER PART OF THE NEXT 24 HRS
BUT WILL BREAK OUT BY FRI NGT AS A WEAKENING FRONT SLIPS THROUGH AND
SKIES BEGIN TO CLEAR AND CEILINGS LIFT. SE WINDS THIS MORNING WILL
