DISCUSSION
SHORT TERM...(THIS MORNING THROUGH SUNDAY)
TODAY, A BRIEF RIDGE
WILL BUILD INTO NORTHWEST CALIFORNIA, REBOUNDING TEMPERATURES BACK
INTO THE UPPER 70S AND 80S FOR MOST INTERIOR VALLEYS. GUSTY NORTH TO
NORTHWEST WINDS ARE EXPECTED AS WELL, ENHANCING UPVALLEY WINDS.
THURSDAY NIGHT INTO FRIDAY MORNING THE WINDS AT HIGHER TERRAIN WILL
REMAIN ELEVATED. FRIDAY NIGHT INTO SATURDAY A WEAK FRONT TO THE
NORTH OF THE AREA WILL INCREASES THE NORTHERLY WINDS AND CLOUD
COVERAGE. AT THIS POINT, RAIN IS NOT EXPECTED (<20% OF 0.01") AS THE
MAIN INFLUENCE OF THE FRONT WILL BE FELT IN OREGON. HOWEVER, THIS
FRONT WILL COOL TEMPERATURES FOR FRIDAY WITH EVEN MORE ADDITIONAL
COOLING SATURDAY. HIGHS ON SATURDAY WILL STRUGGLE TO BREAK 70F WITH
A 20% CHANCE OF >70F IN THE WARMEST VALLEYS WHILE OTHER AREAS
REMAINING IN THE UPPER 50S AND 60S. SATURDAY, THE STRONGEST WINDS
ARE PREDICTED AS A BUILDING HIGH PRESSURE SYSTEM TO THE WEST
INTERACTS WITH A LOW PRESSURE CENTER TO THE EAST. MANY AREAS ARE
EXPECTED TO SEE GUSTS OVER 30 MPH AND THERE ARE EXPECTED TO BE SOME
AREAS WITH GUSTS OVER 40 WITH A 30-40% LIKELIHOOD FOR EXPOSED AREAS.
THE INCREASED MIXING AND LACK OF A MARINE INVERSION SHOULD BRING
PLENTY OF SUNSHINE TO THE COAST.
LONG TERM...(MONDAY THROUGH WEDNESDAY)
SUNDAY HIGH PRESSURE STARTS TO BUILD BACK INTO THE AREA ON SUNDAY.
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 AND IN E-W ORIENTATED VALLEYS.
THESE WINDS WILL ADVECT MARINE AIR, KEEPING 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 TO END THE
WEEKEND. A WARMING TREND IS FORECASTED EARLY WEEK WITH HIGHS FINALLY
WARMING BACK INTO THE UPPER 80S TO LOW 90S INLAND. THE STRONG
NORTHERLY WINDS ARE FINALLY EXPECTED TO DIMINISH STARTING MONDAY AND
TUESDAY, BUT REMAIN BREEZY. OVERNIGHT THE WINDS TURN OFFSHORE AND
MAY HELP KEEP THE COASTAL CLOUDS OUT OF THE AREA. NORTHERLY WINDS
CALM MUCH MORE WEDNESDAY THROUGH THE END OF NEXT WEEK.
AVIATION
VFR CONDITIONS ARE EXPECTED FOR MOST INTERIOR
TERMINALS, INCLUDING KUKI. ALONG THE COAST, WINDS ARE EXPECTED TO
REMAIN SLIGHTLY ELEVATED OVERNIGHT PREVENTING WIDESPREAD COASTAL
STRATUS. HOWEVER, THERE IS STILL A POSSIBILITY FOR COASTAL
STRATUS FORMING AROUND HUMBOLDT BAY EARLY THIS MORNING. IT IS LESS
CLEAR IF STRATUS WILL FORM AROUND KCEC. REGARDLESS, ANY STRATUS
THAT FORMS WILL DISSIPATE AFTER SUNRISE ALONG WITH INCREASING
NORTHERLY WINDS INTO THIS AFTERNOON. GUSTY NORTHERLY WINDS ARE
ANTICIPATED THROUGHOUT THE REGION THIS AFTERNOON AND EVENING.
MARINE
NORTHERLY WINDS CONTINUE TO INCREASE ACROSS THE COASTAL
WATERS. EXPECT MODERATE TO STRONG BREEZES FOR THE SOUTHERN
WATERS, WHILE GENTLE TO MODERATE FOR THE NORTHERN WATERS. THESE
WINDS WILL CONTINUE TO STEADILY INCREASE THROUGH THURSDAY, WITH
STRONG BREEZES EXPANDING INTO THE NORTHERN OUTER WATERS. GALE
FORCE GUSTS ARE LIKELY IN THE LEE OF CAPE MENDOCINO ON THURSDAY
AFTERNOON, BEFORE AN INCREASE IN COVERAGE OCCURS ACROSS THE
SOUTHERN OUTER WATERS THURSDAY EVENING. A GALE WARNING IS IN
EFFECT FOR ZONE 475 FROM THURSDAY AFTERNOON THROUGH LATE FRIDAY
NIGHT. THESE STRONG WINDS COULD EXPANDED INTO THE SOUTHERN INNER
WATERS WITH THE STRENGTHENING PRESSURE GRADIENT NEARSHORE. AT THIS
POINT THE COVERAGE IS NOT ENOUGH (<50%) TO UPGRADE THE SMALL
CRAFT ADVISORY TO GALE FORCE WARNING. NEXT SHIFT WILL CONTINUE TO
EVALUATE ANY CHANGES ON THIS. A SMALL CRAFT ADVISORY FOR WINDS IS
NOW IN EFFECT FOR ZONE 470 AND 450 FROM FRIDAY MORNING THROUGH
LATE FRIDAY NIGHT. WINDS MAY DIMINISH SLIGHTLY ON MONDAY. STEEP,
