..06Z TAF AVIATION FORECAST UPDATE
SYNOPSIS
A COLD FRONT ASSOCIATED WITH A LOW OVER THE GREAT LAKES EXTENDING
SOUTH ACROSS THE CENTRAL PORTION OF THE AREA WILL DEPART TO THE EAST
THIS EVENING. THIS LOW WILL GRADUALLY MOVE SOUTHEAST TOWARDS THE MID-
ATLANTIC COAST THURSDAY BEFORE A SURFACE TROUGH BECOMES ESTABLISHED
INTO THE WEEKEND. HIGH PRESSURE WILL BUILD EAST ON SUNDAY.
NEAR TERM /THROUGH TODAY/
CANCELLED THE WIND ADVISORY FOR CUYAHOGA COUNTY AS WINDS HAVE
BACKED TO SOUTHWESTERLY, KEEPING THE STRONGER FLOW ON THE
LAKE FOCUSED OFFSHORE. THE REMAINING ADVISORIES SHOULD BE ABLE
TO EXPIRE AS EXPECTED AT MIDNIGHT.
THE FORECAST FOR TONIGHT REMAINS ON TRACK WITH SOME OF THE
COLDEST AIR OF THE SEASON ARRIVING. TEMPERATURES WILL FALL INTO
THE LOW TO MID 30S WITH SCATTERED LIGHT RAIN SHOWERS
TRANSITIONING TO SCATTERED LIGHT SNOW SHOWERS. MORE SIGNIFICANT
ADJUSTMENTS WERE MADE TO THE FORECAST FOR THURSDAY EVENING AS A
BAND OF HEAVIER PRECIPITATION IS EXPECTED TO DEVELOP OVER LAKE
ERIE. WHILE SURFACE LOW PRESSURE MOVE SOUTH OFF LAKE MICHIGAN,
ANOTHER LOW LEVEL TROUGH WILL STRENGTHEN OVER LAKE ERIE.
PRECIPITATION WILL INCREASE AS LAKE TO 850MB DELTA T RAMPS UP TO
AROUND 18C, WITH LAKE INDUCED CAPE OF OVER 600 J/KG AND
EQUILIBRIUM LEVELS OVER 16K FEET. THE PRECIPITATION WILL DEVELOP
DURING THE AFTERNOON OVER LAKE ERIE WITH SOUTHWESTERLY SURFACE
WINDS SOUTH OF THE LAKE, THEN MOVE IN OFF THE LAKE AS THE TROUGH
PUSHES SOUTH DURING THE EVENING. TEMPERATURES DURING THIS TIME
FRAME WILL BE CRITICAL FOR PRECIP TYPE AND ARE EXPECTED TO BE
WARMER THE CLOSER YOU GET TO LAKE ERIE. THERMAL PROFILES SUPPORT
SNOW EXCEPT FOR WHERE THE BOUNDARY LAYER MAY BE TOO WARM. THE
QUALITY OF THE SNOW IS DIFFICULT TO DISCERN GIVEN THE
CONVECTIVE COMPONENT WHICH MAY CONTRIBUTE TO PELLETS VS
DENDRITES. IT SEEMS AREAS WITHIN A FEW MILES OF LAKE ERIE WILL
LIKELY BE RAIN WHILE AREAS IN SOUTHERN LAKE, GEAUGA, AND EASTERN
CUYAHOGA MAY BE MORE LIKELY TO SEE A WINDOW OF GOOD SNOW DURING
THE 6-11 PM WINDOW. TRENDED ACCUMULATIONS UP IN THE FORECAST
WITH AROUND 2-4 INCHES IN SOUTHERN GEAUGA COUNTY. IF
TEMPERATURES ARE EVEN A DEGREE OR TWO WARMER THOUGH,
PRECIPITATION COULD FALL AS EITHER A WET SNOW OR MIX WITH RAIN
AND LIMIT ACCUMULATIONS. THE INCREASED SNOW AMOUNTS EXTEND INTO
THE SECONDARY SNOW BELT WITH A COUPLE INCHES ALSO POSSIBLE IN
MEDINA, NORTHERN SUMMIT AND PORTAGE COUNTIES TOO. BY LATE
THURSDAY NIGHT, COVERAGE OF PRECIPITATION EXPANDS AS DEEPER
MOISTURE WRAPS IN FROM THE NORTH BUT TEMPERATURES AT 925MB WARM
ABOVE FREEZING SO MUCH OF THE AREA WILL SEE PRECIPITATION
TRANSITION BACK TO RAIN.
PREVIOUS DISCUSSION...A LARGE NEGATIVELY TILTED TROUGH WILL
CONTINUE TO PUSH SOUTH- SOUTHEAST THROUGH THE PERIOD, GRADUALLY
SHIFTING EAST. THE OCCLUDED LOW AT THE SURFACE, CURRENTLY
LOCATED OVER THE CENTRAL GREAT LAKES, WILL LIKELY RETROGRADE A
BIT ON THURSDAY BEFORE MERGING WITH ANOTHER LOW OFF THE MID-
ATLANTIC COAST BY THE END OF THIS PERIOD. CURRENTLY THIS
AFTERNOON, A STRONG COLD FRONT ASSOCIATED WITH THIS SYSTEM IS
MOVING EAST ACROSS THE AREA, BRINGING WIDESPREAD RAIN SHOWERS
AND GUSTY WINDS. WIND GUSTS ASSOCIATED WITH THIS LINE OF SHOWERS
AND BEHIND THE FRONT HAVE TYPICALLY REMAINED BETWEEN 25-35 MPH
AS A STRONG LLJ OF 30-40 KNOTS SURGES EAST. THESE WINDS WILL BE
LOCALLY ENHANCED FOR COUNTIES DOWNSTREAM OF LAKE ERIE,
ESPECIALLY FROM LORAIN COUNTY EAST TO ERIE COUNTY PA WITH WIND
GUSTS OF 45-50 MPH POSSIBLE. THESE COUNTIES HAVE BEEN
HIGHLIGHTED IN A WIND ADVISORY UNTIL MIDNIGHT TONIGHT, ALTHOUGH
CONDITIONS MAY IMPROVE AN HOUR OR TWO BEFORE EVEN THEN. AS THIS
FRONT PUSHES TO THE EAST LATE TONIGHT, A PUSH OF DRY AIR OVER
THE AREA WILL ALLOW FOR MOSTLY DRY CONDITIONS WITH OVERNIGHT
LOWS FALLING INTO THE LOW 30S.
ON THURSDAY, THE OCCLUDED LOW IS EXPECTED TO CONTINUE TO PIVOT OVER
THE GREAT LAKES AREA AS THE UPPER LEVEL TROUGH GRADUALLY MOVES EAST.
THE POSITIONING OF THIS SYSTEM SHOULD PLACE THE GREATEST SUPPORT FOR
ANY WIDESPREAD SHOWERS TO BE ON THE WESTERN PERIPHERY OF THE AREA
WHERE A STRONG LLJ, ENHANCED VORT MAX, AND STEEP LOW-LEVEL LAPSE
RATES WILL RESULT IN WIDESPREAD SNOW SHOWERS. THIS HAS THE POTENTIAL
TO CLIP THE WESTERN TIER OF COUNTIES WITH ANY SHIFT IN THE LOW
CENTER, BUT WITH SUCH WARM AND WET ANTECEDENT CONDITIONS, NOT
EXPECTING ANY SNOW ACCUMULATION MORE THAN 1 INCH. THERE IS A
POTENTIAL FOR SCATTERED SNOW SHOWERS ACROSS THE REMAINDER OF THE
AREA WITH MOISTURE CONTINUING TO WRAP AROUND THE OCCLUDED LOW AND
OVERALL FORCING REMAINING STRONG ACROSS THE REGION. WITH MUCH COOLER
TEMPERATURES ON THURSDAY IN THE MID 30S, THE BULK OF PRECIPITATION
SHOULD FALL AS FLAKES, ALTHOUGH A RAIN/SNOW MIX REMAINS LIKELY ALONG
THE IMMEDIATE LAKESHORE. BY THURSDAY NIGHT, THE AFOREMENTIONED LOW
BEGINS TO MERGE WITH ANOTHER LOW OFF THE MID-ATLANTIC COAST, MARKING
THE TRANSITION FROM SYNOPTIC DRIVEN PRECIPITATION TO A MORE
PREDOMINANT LAKE EFFECT SYSTEM. MODELS CONTINUE TO SUGGEST A STRONG
CONVERGENT BOUNDARY ACROSS THE SNOWBELT AREA WITH STEEP LAPSE RATES,
STRONG OMEGA FORCING AND EQL NEAR 13KFT. IN ADDITION, 850MB
TEMPERATURES OF -4 TO -6C WILL ALLOW FOR ADEQUATE LAKE INDUCED
INSTABILITY TO DEVELOP. THE GOOD NEWS (OR MAYBE NOT FOR SNOW LOVERS)
IS THAT WARMER AIR IS EXPECTED TO WRAP AROUND THE SURFACE LOW,
KEEPING MOST OF THE PRECIPITATION AS RAIN, ESPECIALLY ACROSS THE
NORTHERN TIER OF COUNTIES, WITH A RAIN/SNOW MIX ELSEWHERE. OVERALL
IMPACTS SHOULD REMAIN MINOR WITH THIS EVENT WITH THE HIGHEST
SNOWFALL AMOUNTS EXPECTED IN THE HIGHER ELEVATIONS, BUT STILL
REMAINING BELOW 2 INCHES. OVERNIGHT LOWS ON THURSDAY WILL BE IN THE
LOW 30S AGAIN.
SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/
N'ERLY FLOW ALOFT ON FRIDAY BECOMES NW'ERLY OVER OUR REGION FRIDAY
NIGHT THROUGH SATURDAY NIGHT AS A VERTICALLY-STACKED LOW WOBBLES
NE'WARD OVER THE NORTHEASTERN UNITED STATES AND CANADIAN MARITIMES.
THE ASSOCIATED SURFACE TROUGH LINGERS OVER THE LAKE ERIE REGION AND
UPPER OH VALLEY THROUGH SATURDAY. DURING SATURDAY NIGHT, A RIDGE AT
THE SURFACE AND ALOFT IS EXPECTED TO BUILD FROM THE UPPER MIDWEST. A
PRIMARILY N'ERLY TO NW'ERLY MEAN LOW-LEVEL FLOW WILL ALLOW A NEAR-
NORMAL AIR MASS FOR LATE NOVEMBER TO PERSIST OVER OUR CWA. AFTERNOON
HIGHS ARE EXPECTED TO REACH THE 40'S ON FRIDAY AND THE MID 40'S TO
LOWER 50'S ON SATURDAY. OVERNIGHT LOWS ARE EXPECTED TO REACH MAINLY
THE MID 30'S TO LOWER 40'S AROUND DAYBREAK SATURDAY AND MAINLY THE
LOWER 30'S TO LOWER 40'S AROUND DAYBREAK SUNDAY.
SCATTERED AND PERIODIC SHOWERS WILL IMPACT OUR CWA THROUGH FRIDAY
NIGHT DUE TO MOIST ISENTROPIC ASCENT PRECEDING SHORTWAVE TROUGH AXES
AND LOW-LEVEL CONVERGENCE/ASCENT ALONG ATTENDANT SURFACE TROUGH AXES
COINCIDING WITH SUFFICIENT MOISTURE AND RELEASING WEAK POTENTIAL
INSTABILITY IN THE LOWEST 1 KM AGL. A SUFFICIENTLY-COLD/MOIST
LOW/MID-LEVEL ATMOSPHERIC COLUMN OVER/DOWNWIND OF ~12C LAKE ERIE,
THE SEEDER-FEEDER PROCESS, AND APPRECIABLE LAKE-INDUCED CAPE WILL
ALLOW LAKE-ENHANCED PRECIP, STEADY TO HEAVY AT TIMES, TO OCCUR OVER
AND GENERALLY SOUTH AND THEN SOUTHEAST OF LAKE ERIE AS N'ERLY TO
NW'ERLY MEAN LOW-LEVEL FLOW ON FRIDAY BECOMES PRIMARILY NW'ERLY
FRIDAY NIGHT. GIVEN PROJECTED AIR TEMPERATURES AND WET-BULB
TEMPERATURES AT THE SURFACE, THE BULK OF PRECIP IS EXPECTED TO FALL
AS RAIN, BUT WET SNOW IS FORECAST TO MIX WITH RAIN FRIDAY MORNING
INLAND FROM LAKE ERIE, ESPECIALLY IN THE HIGHER TERRAIN OF NORTHERN
OH AND NW PA. NO ADDITIONAL SNOW ACCUMULATIONS ARE EXPECTED.
LAKE-ENHANCED RAIN SHOWERS ARE EXPECTED TO TRANSITION TO PURE LAKE-
EFFECT RAIN SHOWERS ON SATURDAY AS MID-LEVEL MOISTURE PLUMMETS, THE
SEEDER-FEEDER PROCESS ENDS, AND YET THE LOW-LEVEL ATMOSPHERIC COLUMN
REMAINS SUFFICIENTLY-COLD/MOIST AND LAKE-INDUCED CAPE REMAINS
APPRECIABLE. LAKE-EFFECT RAIN SHOWERS ARE FORECAST TO TAPER SATURDAY
NIGHT AS LOW-LEVEL DRY AIR ADVECTION AND A LOWERING SUBSIDENCE
INVERSION CAUSE LAKE-INDUCED CAPE TO WANE. THE LAKE-ENHANCED/EFFECT
SHOWERS ARE EXPECTED IN/NEAR THE SNOWBELT OF NE OH AND NW PA AS MEAN
LOW-LEVEL FLOW BACKS SLOWLY FROM NW'ERLY TO WNW'ERLY. SUFFICIENT
NOCTURNAL COOLING AND WET-BULB EFFECT MAY ALLOW A FEW WET SNOWFLAKES
TO MIX WITH RAIN IN INTERIOR NW PA DURING EARLY SUNDAY MORNING, BUT
NO SNOW ACCUMULATIONS ARE EXPECTED. ODDS FAVOR FAIR WEATHER OUTSIDE
THE LAKE-ENHANCED/EFFECT PRECIP SATURDAY THROUGH SATURDAY NIGHT.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
THE NARROW RIDGE AT THE SURFACE AND ALOFT BUILDS E'WARD ACROSS OUR
CWA ON SUNDAY AND AFTERNOON HIGHS SHOULD REACH THE MID 40'S TO LOWER
50'S. ODDS FAVOR FAIR WEATHER IN MOST OF OUR CWA DUE TO STABILIZING
SUBSIDENCE ACCOMPANYING THE RIDGE. LINGERING AND LIGHT LAKE-EFFECT
RAIN SHOWERS OVER AND GENERALLY EAST OF LAKE ERIE, ACROSS THE
PRIMARY SNOWBELT AND VICINITY, ARE EXPECTED TO DISSIPATE EARLY
SUNDAY EVENING AS LAKE-INDUCED INSTABILITY CONTINUES TO WANE VIA LOW-
LEVEL DRY AIR ADVECTION AND A LOWERING SUBSIDENCE INVERSION.
CYCLONIC W'ERLY TO NW'ERLY FLOW ALOFT, EMBEDDED SHORTWAVE TROUGHS,
AND NET SURFACE TROUGHING ARE FORECAST TO IMPACT THE EASTERN GREAT
LAKES AND UPPER OH VALLEY ON SUNDAY NIGHT THROUGH WEDNESDAY. IN
ADDITION, A SURFACE COLD FRONT IS EXPECTED TO SWEEP E'WARD ACROSS
OUR CWA MONDAY EVENING THROUGH MONDAY NIGHT. PERIODIC AND SCATTERED
RAIN SHOWERS ARE EXPECTED TO ACCOMPANY THE SHORTWAVE TROUGHS AND THE
COLD FRONT. BEHIND THE FRONT, THE LOW-LEVEL AIR MASS IS EXPECTED TO
BECOME SUFFICIENTLY-COLD/MOIST FOR LAKE-EFFECT RAIN SHOWERS TO
STREAM GENERALLY E'WARD AND SE'WARD FROM LAKE ERIE. SUFFICIENT LOW-
LEVEL CAA, NOCTURNAL COOLING, AND WET-BULB EFFECT MAY ALLOW RAIN TO
MIX WITH WET SNOW TUESDAY MORNING AND WEDNESDAY MORNING, ESPECIALLY
IN HIGHER TERRAIN INLAND FROM LAKE ERIE. SIGNIFICANT AND IMPACTFUL
SNOW ACCUMULATIONS ARE NOT EXPECTED AT THIS TIME.
OVERNIGHT LOWS SHOULD REACH MAINLY THE UPPER 30'S TO LOWER 40'S
AROUND DAYBREAK MONDAY. HIGHS SHOULD REACH MAINLY THE LOWER TO MID
50'S MONDAY AFTERNOON, BEFORE THE COLD FRONT PASSAGE. OVERNIGHT LOWS
SHOULD THEN REACH THE MID 30'S TO NEAR 40F AROUND DAYBREAK TUESDAY.
COOLER AFTERNOON HIGHS IN THE UPPER 30'S TO MID 40'S ARE EXPECTED ON
TUESDAY AND WEDNESDAY, RESPECTIVELY. WEDNESDAY MORNING SHOULD
FEATURE LOWS IN THE UPPER 20'S TO MID 30'S AROUND DAYBREAK.
AVIATION /06Z THURSDAY THROUGH MONDAY/
THE MAIN AVIATION WEATHER MESSAGE WITH THIS TAF UPDATE WILL BE
CONDITIONS WILL BECOME MORE IMPACTFUL WITH CEILINGS LOWERING AND
RAIN/SNOW SHOWERS CAUSING REDUCED VISIBILITY LATER THIS MORNING
AND THROUGHOUT THE REST OF THE DAY. WE ARE STARTING OFF WITH
MOSTLY VFR CONDITIONS AS OF 06Z THIS EARLY MORNING. CEILINGS
WILL LOWER TO MVFR AND AT TIMES LOW END MVFR LATER THIS MORNING
WITH A WAVE OF RAIN/SNOW SHOWERS THAT WILL MOVE IN BY 12Z. THERE
ARE TEMPO GROUPS HIGHLIGHTING A 4 HOUR WINDOW BETWEEN ROUGHLY 10Z
AND 16Z AT EACH TAF SITE TO MENTION THE POTENTIAL OF 3SM TO 5SM
VISIBILITY REDUCTIONS WITH THE LIGHT TO MODERATE RAIN SHOWERS
MIXING WITH AND EVENTUALLY CHANGING TO MOSTLY SNOW SHOWERS LATER
THIS MORNING AND LINGERING THROUGH THE REST OF THE DAY INTO THIS
EVENING. WE HAVE GENERAL CEILINGS LOWERING TO 2500 FEET LATER
TODAY BUT MENTION SOME TIME PERIODS LATER THIS MORNING WHERE
IT COULD DROP TO 1500 FEET WITH BANDS OF PRECIPITATION MOVING
ACROSS THE AREA. WE HAVE THE MENTION OF SCATTERED LIGHT SNOW
SHOWERS WITH 6SM THROUGH THE AFTERNOON AND EVENING IN ALL TAFS.
BUT THERE IS A PROB30 GROUP BETWEEN 23Z AND 03Z THIS EVENING
WHERE WE THERE COULD BE ANOTHER UPTICK OF HEAVIER LAKE EFFECT SNOW
SHOWERS THAT COULD BRING DOWN CEILINGS AND VISIBILITIES AT
LOCAL AIRPORTS. WINDS WILL BE GENERALLY FROM THE WEST-SOUTHWEST
THIS MORNING 8 TO 12 KNOTS WITH A FEW ISOLATED GUSTS UP TO 20
KNOTS. THAT GUST POTENTIAL WILL MAINLY BE FOR ERI THROUGH THE
EARLY MORNING. WINDS WILL BECOME MORE WESTERLY LATER IN THE TAF
PERIOD BETWEEN 5 AND 10 KNOTS.
OUTLOOK...NON-VFR CONDITIONS WILL BE POSSIBLE FRIDAY THROUGH
SATURDAY IN SCATTERED LAKE EFFECT RAIN SHOWERS, POSSIBLY MIXED
WITH SNOW SHOWERS AT TIMES EARLY ON FRIDAY. GUSTY WINDS FROM
THE NORTH AND NORTHWEST UP TO 35 KNOTS WILL ALSO BE POSSIBLE
FRIDAY THROUGH SATURDAY, ESPECIALLY AREAS CLOSER TO THE
LAKESHORE AS AS WELL NEOH AND NWPA.
MARINE
GALE WARNING IN EFFECT UNTIL LATE THIS EVENING OR VERY EARLY
THURSDAY MORNING FOR U.S. WATERS EAST OF THE ISLANDS. A SMALL CRAFT
ADVISORY IS IN EFFECT UNTIL 7 PM EST THURSDAY FOR NEARSHORE WATERS
FROM MAUMEE BAY TO THE ISLANDS.
A LOW WATER ADVISORY IS IN EFFECT UNTIL 7 AM THURSDAY WEST OF
VERMILION DUE TO A SEICHE, WHICH WILL LIKELY CAUSE WATER LEVELS TO
FALL TO VALUES BELOW THE CRITICAL MARK FOR SAFE NAVIGATION (I.E. 3"
ABOVE LOW WATER DATUM) THIS EVENING THROUGH THE WEE HOURS OF
THURSDAY MORNING. WATER LEVELS ARE FORECAST TO REBOUND TO ABOVE THE
CRITICAL MARK BY DAYBREAK THURSDAY.
A TROUGH LINGERS OVER LAKE ERIE FOR THE TIME BEING. WITHIN THIS
TROUGH, A LOW WILL CONTINUE TO DEEPEN IN VICINITY OF SOUTHERN ON AND
LAKE HURON THROUGH TONIGHT. A COLD FRONT TRAILING THIS LOW WILL
CONTINUE TO SWEEP E'WARD ACROSS LAKE ERIE THROUGH THIS EVENING.
E'ERLY TO S'ERLY WINDS AROUND 5 TO 20 KNOTS AHEAD OF THE FRONT VEER
TO SW'ERLY TO W'ERLY AND INCREASE TO 25 TO 35 KNOTS IMMEDIATELY
BEHIND THE FRONT. SEVERAL HOURS AFTER THE FRONT'S PASSAGE, SW'ERLY
TO W'ERLY WINDS ARE EXPECTED TO EASE TO AROUND 15 TO 25 KNOTS. WAVES
OF 3 FEET OR LESS AHEAD OF THE FRONT ARE EXPECTED TO BUILD TO AS
LARGE AS 6 FEET IN THE WESTERN BASIN AND AS LARGE AS 7 TO 14 FEET
FARTHER EAST. SW'ERLY TO W'ERLY WINDS AROUND 15 TO 25 KNOTS ON
THURSDAY MORNING ARE EXPECTED TO VEER GRADUALLY TO NW'ERLY LATER
THURSDAY THROUGH THURSDAY NIGHT AS A TROUGH AXIS SWEEPS SE'WARD
ACROSS THE LAKE. NW'ERLY WINDS ARE EXPECTED TO REACH 30 KNOTS AT
TIMES OVER THE CENTRAL BASIN THURSDAY NIGHT. WAVES AS LARGE AS 5 TO
10 FEET ARE EXPECTED, WHICH WILL WARRANT EVENTUAL SPATIAL EXPANSION
AND TEMPORAL EXTENSION OF THE SMALL CRAFT ADVISORY.
W'ERLY TO NW'ERLY WINDS AROUND 15 TO 25 KNOTS ARE FORECAST FRIDAY
THROUGH SATURDAY. THESE WINDS ARE EXPECTED TO BE AS STRONG AS 30
KNOTS AT TIMES OVER THE CENTRAL BASIN ON FRIDAY. WAVES AS LARGE AS 4
TO 8 FEET, WITH OCCASIONAL 9 TO 10 FOOTERS, ARE FORECAST. NW'ERLY TO
W'ERLY WINDS AROUND 15 TO 25 KNOTS SATURDAY EVENING ARE EXPECTED TO
BACK TO SW'ERLY AND EASE TO AROUND 5 TO 15 KNOTS ON SUNDAY THROUGH
SUNDAY NIGHT AS A RIDGE BUILDS FROM THE UPPER MIDWEST AND EVENTUALLY
CRESTS E'WARD ACROSS LAKE ERIE. WAVES SUBSIDE GRADUALLY TO 5 FEET OR
LESS BY DAYBREAK SUNDAY AND TO 3 FEET OR LESS BY DAYBREAK MONDAY. ON
MONDAY, THE RIDGE EXITS E'WARD AS A COLD FRONT APPROACHES FROM THE
UPPER MIDWEST. THIS FRONT SHOULD SWEEP E'WARD ACROSS WESTERN AND
CENTRAL LAKE ERIE DURING THE EARLY EVENING AND CAUSE SW'ERLY WINDS
AROUND 10 TO 20 KNOTS TO VEER TO W'ERLY. WAVES ARE FORECAST TO BE
MAINLY 3 FEET OR LESS, BUT OCCASIONAL 4 FOOTERS ARE POSSIBLE BEHIND
THE FRONT, ESPECIALLY IN OPEN U.S. WATERS OF THE CENTRAL BASIN.
