DISCUSSION
SHORT TERM
TONIGHT A WEAK FRONT IS APPROACHING THE AREA AND
THIS IS EXPECTED TO BRING SOME LIGHT RAIN TO HUMBOLDT AND DEL
NORTE COUNTIES EARLY WEDNESDAY MORNING. FARTHER SOUTH AND EAST A
FEW SPRINKLES ARE POSSIBLE, BUT THE BIGGEST CHANGE WILL BE MUCH
COOLER TEMPERATURES. MOST OF THE INTERIOR VALLEYS ARE EXPECTED TO
SEE TEMPERATURES ONLY WARM INTO THE UPPER 60S TO MID 70S. LAKE
COUNTY MAY SEE UPPER 70S IN SOME LOCATIONS. THE COAST WILL LIKELY
SEE CLOUDS SCATTER OUT ONCE THE FRONT MOVES THROUGH AND THIS MAY
HELP THEM WARM TO AROUND 60. THURSDAY A BRIEF RIDGE BUILDS IN AND
THIS BRINGS A REBOUND IN THE TEMPERATURES WITH HIGHS WARMING BACK
INTO THE 80S IN MOST OF THE INTERIOR VALLEYS. GUSTY NORTH TO
NORTHWEST WINDS ARE EXPECTED AS WELL. THURSDAY NIGHT INTO FRIDAY
MORNING THE WINDS OVER THE HIGHER TERRAIN WILL REMAIN ELEVATED.
FRIDAY NIGHT INTO SATURDAY A WEAK FRONT MOVES BY TO THE NORTH OF
THE AREA. THIS INCREASES THE NORTHERLY WINDS MORE AND BRINGS SOME
CLOUDS TO THE AREA. AT THIS POINT RAIN IS NOT EXPECTED, BUT IS
JUST NORTH OF THE AREA. THIS WILL BRING COOLER TEMPERATURES FRIDAY
WITH ADDITIONAL COOLING ON SATURDAY. HIGHS ON SATURDAY WILL
BARELY MAKE IT INTO THE 70S IN THE WARMEST VALLEYS WITH MANY AREAS
REMAINING IN THE UPPER 50S AND 60S. SATURDAY IS EXPECTED TO SEE
THE STRONGEST WINDS ACROSS MUCH OF THE AREA. MANY AREAS ARE
EXPECTED TO SEE GUSTS OVER 30 MPH AND THERE ARE EXPECTED TO BE
SOME AREAS WITH GUSTS OVER 40. THE NBM SHOWS A 50 TO 80 PERCENT
CHANCE OF GUSTS OVER 40 MPH ALONG THE COAST AND OVER THE HIGHER
TERRAIN. THE INCREASED MIXING AND LACK OF A MARINE INVERSION
SHOULD BRING PLENTY OF SUNSHINE TO THE COAST. MKK
LONG TERM
SUNDAY HIGH PRESSURE STARTS TO BUILD BACK INTO THE
AREA. THE NORTHERLY WINDS REMAIN STRONG AS THE SYSTEM THAT MOVED
BY TO THE NORTH OF THE AREA DROPS INTO THE GREAT BASIN. THESE MAY
WEAKEN SLIGHTLY IN AREAS AWAY FROM THE COAST. THESE WINDS WILL
KEEP THE AREAS NEAR THE COAST AND UP THE RIVER VALLEYS COOLER THAN
AREAS FARTHER INLAND. HIGHS AWAY FROM THE COAST SHOULD WARM INTO
THE 70S AGAIN. MONDAY AND TUESDAY THE WARMING CONTINUES WITH HIGHS
FINALLY WARMING BACK INTO THE UPPER 80S TO LOW 90S. THE WINDS ARE
FINALLY EXPECTED TO START TO DIMINISH MONDAY AND TUESDAY, BUT
REMAIN BREEZY. OVERNIGHT THE WINDS TURN OFFSHORE AND MAY HELP KEEP
THE COASTAL CLOUDS OUT OF THE AREA. MKK
AVIATION
A WEAK FRONT IS APPROACHING THE COAST THIS MORNING.
THIS WILL BRING SOME LOWER CONDITIONS TO THE HUMBOLDT AND DEL
NORTE COUNTY COASTS AS IT MOVES THROUGH EARLY THIS MORNING. THIS
MAY BRING OCCASIONAL IFR CONDITIONS, BUT GENERALLY MVFR
CONDITIONS. THIS AFTERNOON BREEZY NORTH WINDS ARE EXPECTED IN THE
SOUTH WITH GUSTS TO 20 TO 25 KT ACROSS MUCH OF MENDOCINO AND LAKE
COUNTIES. TONIGHT THERE MAY SOME COASTAL CLOUDS, BUT IF THESE
OCCUR, THEY ARE EXPECTED TO BE TOWARDS MORNING. MKK
MARINE
LIGHT SOUTHERLY WINDS ARE IN PLACE IN THE NORTHERN
WATERS AS A WEAK FRONT MOVES THROUGH THIS MORNING. LATER THIS
MORNING THE WINDS ARE EXPECTED TO BECOME NORTHERLY AGAIN ACROSS
THE AREA AND START TO INCREASE. INITIALLY THIS WILL MAINLY BE IN
THE SOUTHERN WATERS. THESE WINDS ARE EXPECTED TO INCREASE TO
AROUND 20 TO 25 WITH GUSTS TO 30 KT. THERE MAY BE A FEW GALE FORCE
GUSTS IN THE LEE OF CAPE MENDOCINO, BUT WEDNESDAY THESE DO NOT
APPEAR WIDESPREAD ENOUGH TO WARRANT A GALE WATCH.
THURSDAY THE NORTHERLY INCREASE TO 20 TO 30 KT BY THE AFTERNOON
WITH GUSTS TO 35 KT SOUTH OF CAPE MENDOCINO. SO HAVE ISSUED A GALE
WATCH STARTING THURSDAY AFTERNOON. THIS GOES OUT THROUGH EARLY
SATURDAY, BUT STRONG WINDS ARE EXPECTED TO CONTINUE TO INCREASE
INTO SUNDAY WITH SUSTAINED GALES POSSIBLE. A GALE WATCH WILL ALSO
LIKELY BE NEEDED FOR THE NORTHERN WATERS, BUT THIS IS EXPECTED TO
BE LATER AND CONFIDENCE IS LOWER. WINDS MAY DIMINISH SLIGHTLY ON
