DISCUSSION
A TROUGH MOVING THROUGH THE PACIFIC NORTHWEST SUNDAY
WILL BRING A FEW HIGH CLOUDS AND BRING SLIGHTLY LIGHTER WINDS THAN
THE PREVIOUS DAYS. THIS WILL BRING SLIGHTLY WARMER HIGH TEMPERATURES
TO THE INTERIOR AREAS. WINDS COULD STILL BE BREEZY WITH AFTERNOON
GUSTS UP TO 20 MPH.
WET WEATHER IS EXPECTED TO RETURN TO PORTIONS OF THE AREA ON MONDAY.
MODELS ARE IN GOOD AGREEMENT FOR GENERALLY LIGHT TO LOCALLY MODERATE
RAIN FOR HUMBOLDT AND DEL NORTE COUNTIES STARTING LATE MONDAY
MORNING AND THROUGH THE DAY. TOTAL RAIN AMOUNTS IN DEL NORTE RANGE
FROM JUST UNDER 1" TO LOCALIZED 1.5" OR MORE IN THE MOUNTAINS.
PRECIPITATION DROPS OFF SIGNIFICANTLY FARTHER SOUTH, WITH ONLY
AROUND 0.10" TO 0.50" IN HUMBOLDT AND COASTAL MENDOCINO, AND ONLY A
FEW HUNDREDTHS IN TRINITY AND INTERIOR MENDOCINO. MODELS HAVE
GENERALLY BEEN TRENDING WETTER, AND WESTERLY FLOW COULD SUPPORT
HIGHER RAIN AMOUNTS IN HUMBOLDT AND DEL NORTE. SOME HIGH-RES MODELS
ARE SHOWING THIS POSSIBILITY WITH THE REFS SHOWING FAIRLY HIGH
CHANCES (70%) FOR OVER AN INCH OF RAIN FOR NORTHERN HUMBOLDT. LAKE
COUNTY MAY ONLY SEE A FEW SPRINKLES, IF ANY. SOUTH WINDS MAY BE
BREEZY IN DEL NORTE, ESPECIALLY IN THE HIGHER TERRAIN AND COASTAL
HEADLANDS WHERE GUSTS COULD BRIEFLY REACH 30 TO 35 MPH MONDAY
AFTERNOON. INTERIOR HIGH TEMPERATURES WILL ALSO DROP 5 TO 10
DEGREES, WITH 60S OR 70S FORECAST FOR MOST INTERIOR VALLEYS.
THIS FRONT QUICKLY MOVES OUT OF THE AREA TUESDAY WITH TEMPERATURES
REBOUNDING SLIGHTLY TO THE HIGH 70S. LOW TEMPERATURES TUESDAY
MORNING MAY DROP INTO THE 30S IN THE COLDEST VALLEYS, INCLUDING
HAYFORK AND RUTH. FROST IS CURRENTLY NOT EXPECTED, BUT THIS WILL
NEED TO BE WATCHED.
WARMING TEMPERATURES ARE EXPECTED TO START ON WEDNESDAY AND WILL
LIKELY CONTINUE TO TO WARM THROUGH THE END OF THE WEEK AND INTO THE
WEEKEND. INTERIOR HIGH TEMPERATURES IN THE 90S AND POSSIBLY INTO THE
TRIPLE DIGITS FOR THE WARMEST VALLEYS ARE POSSIBLE BY THURSDAY AND
FRIDAY. WARM AND DRY WEATHER IS EXPECTED TO CONTINUE INTO THE
WEEKEND. JB
AVIATION...(6Z TAFS)
ONLY A FEW PATCHES OF COASTAL STRATUS ARE
BEING OBSERVED SO FAR. A WEAK MARINE INVERSION WILL LIKELY KEEP
STRATUS IMPACTS MINIMAL OVERNIGHT, STILL SOME BRIEF MVFR TO VFR
CEILINGS ARE POSSIBLE. LOW CEILINGS WILL CLEAR SHORTLY AFTER
SUNRISE. HIGH CLOUDS WILL INCREASE TODAY, BUT CONDITIONS WILL
REMAIN VFR AT ALL TERMINALS. BREEZY NORTH WINDS OF UP TO 20 KTS
ARE POSSIBLE THIS AFTERNOON. JB
MARINE
WINDS EASE TODAY AS A FRONT APPROACHES THE AREA FROM THE
NORTH. THE MAIN EXCEPTION IS IN THE LEE OF CAPE MENDOCINO WHERE NEAR-
GALE TO GALE FORCE GUSTS ARE POSSIBLE THIS AFTERNOON. NORTH WINDS
CONTINUE TO DIMINISH TONIGHT AND TURN SOUTHERLY AS THE FRONT
APPROACHES. GENERALLY, SEAS ARE FORECAST TO SUBSIDE SIGNIFICANTLY AS
NORTH WINDS EASE, AND COULD BE AS LOW AS 4 FT SUNDAY NIGHT INTO
MONDAY. SOUTH WINDS COULD BE STRONG NORTH OF THE CAPE AND BRIEFLY
NEAR OR EXCEED GALE FORCE IN THE NORTHERN OUTER WATERS. A POST
FRONTAL SWELL OF AROUND 7 FT AT 10 SECONDS ARRIVES MONDAY NIGHT INTO
TUESDAY. THIS COULD BRING COMBINED SEAS BACK TO 8 TO 9 FT. STRONG
NORTHERLY WINDS RETURN TUESDAY AND ARE LIKELY TO CONTINUE THROUGH
THE WORK WEEK. JB
FIRE WEATHER
BREEZY WEST-NORTHWEST WINDS CONTINUE TODAY, BUT ARE
EXPECTED TO BE SLIGHTLY LIGHTER THAN PREVIOUS DAYS. GUSTS OF 20 TO
25 MPH ARE POSSIBLE OVER EXPOSED RIDGES AND IN CHANNELED TERRAIN.
MINIMUM RELATIVE HUMIDITY IN THE AFTERNOON IS EXPECTED TO DROP INTO
THE TEENS OR 20S FOR THE EASTERN PORTIONS OF THE AREA (TRINITY,
EASTERN MENDOCINO, AND LAKE COUNTIES). THESE AFTERNOON WINDS ALONG
WITH LOW RHS WILL BRING ELEVATED TO LOCALLY CRITICAL FIRE WEATHER
CONDITIONS. WETTING RAIN IS VERY LIKELY FOR DEL NORTE, HUMBOLDT,
COASTAL MENDOCINO, AND WESTERN TRINITY. PROBABILITIES DROP OFF
FARTHER SOUTH AND EAST TO NEAR ZERO IN LAKE AND SOUTHERN MENDOCINO.
