Area forecast discussion, May 27, 1:20 AM EDT, 2 hours 49 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
120 AM EDT SUN MAY 27 2012
.SYNOPSIS...
SUBTROPICAL STORM BERYL WILL SLOWLY SHIFT SOUTHWEST TOWARD THE
FLORIDA-GEORGIA BORDER THROUGH SUNDAY NIGHT. THE SYSTEM IS THEN
EXPECTED TO STALL ACROSS SOUTHERN GEORGIA/NORTHERN FLORIDA BEFORE
MOVING BACK UP THE SOUTHEAST COAST DURING THE MIDDLE OF NEXT WEEK.
A FRONT APPROACHING FROM THE WEST COULD IMPACT THE AREA FOR THE
LATE WEEK PERIOD.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE TROPICAL STORM WATCH HAS BEEN CANCELLED FOR CHARLESTON AND
BERKELEY COUNTIES IN SOUTH CAROLINA. TROPICAL STORM WARNINGS
REMAIN INTACT OTHERWISE.
LATE THIS EVENING...MOSTLY CLEAR SKIES AND DRY WEATHER PREVAILING
OVER JUST ABOUT ALL OF OUR FORECAST AREA. THESE TRANQUIL CONDITIONS
WILL PROBABLY HOLD UP FOR MUCH OF THE NIGHT BEFORE EFFECTS FROM
SUBTROPICAL STORM BERYL SPREAD OVER THE FORECAST AREA DURING THE
LATTER HALF OF THIS WEEKEND.
OVERNIGHT...WE MAINTAINED TRENDS FOR INCREASING CLOUDS. WE
TRIMMED BACK POPS THROUGH 4 AM GIVEN RECENT RADAR AND 18Z MODEL
TRENDS BUT CONTINUED SOME COASTAL CHANCES LATE. OTHERWISE...OVERNIGHT
FORECAST ON TRACK AND LITTLE CHANGE WAS NEEDED ON RECENT UPDATES.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH TUESDAY/...
SUNDAY AND SUNDAY NIGHT...IT WILL BE DURING THIS TIME THAT THE WORST
IMPACTS FROM THE APPROACH OF BERYL WILL OCCUR IN OUR CWFA...AS THE
SYSTEM MOVES ONSHORE NEAR THE GEORGIA/FLORIDA BORDER AROUND 06Z
MONDAY. BERYL IS BEING DRIVEN BY A STRONG BLOCKING RIDGE THAT WILL
BE SITUATED FROM OLD MEXICO TO THE OH/TN VALLEYS...AND THEN
EXTENDING INTO THE MID-ATLANTIC STATES AND THE WESTERN ATLANTIC.
THIS WILL STEER THE SYSTEM MORE WESTWARD AND PUTS THE FORECAST AREA
INTO THE NE QUAD RELATIVE TO THE STORMS MOTION. THE DRY AIR IN PLACE
ON THE WEST SIDE OF THE BERYL INITIALLY WILL HOLD IN PLACE LONGEST
ACROSS OUR WESTERN ZONES...BUT WITH STRONG LOW LEVEL CONVERGENCE
AND CONSIDERABLE ATMOSPHERIC MOISTURE OUR RAIN PROBABILITIES WILL
STEADILY CLIMB FROM EAST TO WEST THROUGHOUT THE DAY. SOME OF THE
OUTERMOST RAIN BANDS WILL BE IMPACTING THE COASTAL ZONES AT
DAYBREAK...WITH POPS TO THEN CLIMB FOR THE AFTERNOON. HIGHEST RAIN
CHANCES WILL BE FROM BEAUFORT AND COASTAL JASPER TO
MCINTOSH...LIBERTY AND LONG COUNTIES WHERE 60-70 POPS ARE CURRENTLY
EXPECTED. PROBABILITIES WILL FURTHER RISE ABOUT 10 PERCENT ALL AREAS
SUNDAY NIGHT. RAIN WILL BE HEAVY AT TIMES...ESPECIALLY OVER SOUTHERN
SECTIONS AND ALONG THE COAST. /SEE OUR HYDROLOGY SECTION BELOW FOR
FURTHER DETAILS/.TROPICAL STORM FORCE WINDS WILL START OCCURRING IN
THE MORNING AND PERSIST INTO THE EVENING FROM BEAUFORT AND JASPER
COUNTIES SOUTH OF MCINTOSH...LIBERTY AND LONG COUNTIES. THE TROPICAL
STORM FORCE WINDS TO BE LIMITED TO THESE SE GA ZONES THE REST OF
SUNDAY NIGHT. FURTHER NORTH AND WEST THE WINDS WILL NOT BE AS
STRONG...BUT BREEZY TO WINDY CONDITIONS WILL STILL RESULT WITH THE
TIGHT PRESSURE GRADIENT AROUND BERYL TO OCCUR. THE ONSHORE FLOW AND
AN INCREASE/THICKENING OF CLOUD COVER WILL NOT ALLOW TEMPS TO CLIMB
AS WARM AS THEY DID ON SATURDAY...BUT THERE IS STILL ENOUGH
SUBSIDENCE IN ADVANCE OF BERYL TO ALLOW FOR MID AND UPPER 80S TO
OCCUR AWAY FROM THE COAST. IT/LL BE WARM AND VERY HUMID SUNDAY
NIGHT...WITH MINS NO LOWER THAN THE UPPER 60S AND LOWER 70S.
MONDAY AND MONDAY NIGHT...BERYL WILL BE INLAND OVER NORTHERN
FLORIDA/SOUTHERN GEORGIA AND WEAKENING...WITH THE LATEST PROJECTIONS
SHOWING IT DOWNGRADED TO A TROPICAL DEPRESSION DURING THAT TIME. THE
RIDGING ALOFT BEGINS TO START BREAKING DOWN...AS A BROAD AND DEEP
LAYERED TROUGH IS FOUND MOVING INTO THE PLAINS STATES. DEPENDING
UPON HOW FAR INLAND THE SYSTEM IS ABLE TO MOVE BEFORE STALLING WILL
DETERMINE HOW STRONG OUR LOW LEVEL CONVERGENCE WILL BE. BUT AMPLE
FORCING AND DEEP MOISTURE SUPPORTS KEEPING AT LEAST 40-60 POPS
MONDAY AND 30-50 POPS MONDAY NIGHT. HIGHEST CHANCES WILL BE ACROSS
OUR SOUTHERN ZONES DURING THIS TIME. PERIODS OF LOCALLY HEAVY
RAINFALL CAN AGAIN OCCUR WITH THE RAIN BANDS AROUND BERYL. WINDS
COULD STILL BE NEAR TROPICAL STORM FORCE EARLY MONDAY NEAR PARTS OF
THE ALTAMAHA RIVER...OTHERWISE WINDS WILL BE ON A DECREASING TREND.
DESPITE PLENTY OF CLOUDS THERE LOOKS TO BE JUST ENOUGH INSOLATION TO
BOOST TEMPS TO THE LOWER AND MIDDLE 80S DURING THE DAY...WHILE THE
SAME CLOUD COVER WILL PREVENT MINS FROM FALLING ANY LOWER THAN THE
UPPER 60S AND LOWER 70S.
TUESDAY...THE NORTHERN AND SOUTHERN STREAMS WILL START TO PHASE AND
THE ASSOCIATED DEEP TROUGHING WILL RE CURVE BERYL AND TURN IT BACK
TOWARD THE NE. SHE MAY RETURN TO TROPICAL STORM STATUS FOR AWHILE AS
SHE MOVES BACK INTO THE ATLANTIC OFF THE NC/SC COASTS...BUT THE
SYSTEM WILL BE TRAVELING AT A QUICKER PACE THAN WHAT IT WAS AS IT
APPROACHED THE COAST EARLIER. SO IT REMAINS TO BE SEEN WHETHER OR
NOT ANY TROPICAL STORM CONDITIONS WILL BE ABLE TO OCCUR AGAIN IN OUR
CWFA. THERE IS STILL AMPLE MOISTURE AND FORCING TO KEEP POPS AT
LEAST IN THE 30-50 PERCENT RANGE AT A MINIMUM. TEMPS LOOK TO REACH
THE MID AND UPPER 80S.
REGARDING THE RISK FOR TORNADOES...WITH 0-1 KM BULK SHEAR OF 30-35
KNOTS AND THE 0-3 KM VGP APPROACHING 0.20 THERE IS STILL AT LEAST A
SMALL RISK OF ISOLATED TORNADOES LATE SUNDAY INTO EARLY MONDAY.
THE BEST CHANCES LOOK TO BE ACROSS OUR CENTRAL AND SOUTHERN ZONES
IN CLOSER PROXIMITY TO THE TRACK OF BERYL.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
FORECAST UNCERTAINTY PERSISTS INTO THE MID WEEK PERIOD DUE TO
DIFFERING MODEL REPRESENTATIONS OF THE DEPARTING LOW SYSTEM TO THE
NORTHEAST. WILL LEAN TOWARD A MORE CONSERVATIVE SOLUTION
INDICATING A WEAKER AND SLOWER MOVING SYSTEM UP THE CAROLINA
COASTLINE...AND THUS MAINTAIN SOLID RAIN CHANCES INTO WEDNESDAY.
WILL THEN INDICATE LOWER RAIN POTENTIAL BEHIND THE LOW PRESSURE
SYSTEM BY THURSDAY...WITH SCATTERED CONVECTION MORE DIURNALLY
DRIVEN IN NATURE. MEDIUM RANGE MODELS ARE SUGGESTING UPPER LEVEL
TROUGHING AND A COLD FRONT COULD IMPACT THE AREA FROM THE WEST
LATE NEXT WEEK.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
KCHS...RIBBONS OF MVFR CIGS WERE NEARING THE TERMINAL FROM THE ATLC
AT 05Z PER UPSTREAM OBSERVATIONS AT KGGE/KCRE AND SATELLITE
IMAGERY. THERE PROBABLY WILL BE IN AND OUT MVFR CONDITIONS UNTIL
LATER TONIGHT WHEN SOME LOWER END MVFR CIGS EXPAND.
IT LOOKS LIKE PREVAILING SURFACE WIND GUSTS WILL ENSUE CLOSER TO
DAYBREAK ON SUNDAY...THEN INCREASING NE FLOW TODAY...BECOMING E THIS
AFTERNOON WITH GUSTS 25-30 KT POSSIBLE IN SHOWERS AFTER 12Z. FOR NOW
WE HAVE MAINTAINED VCSH CHANCES FOR SHOWERS WITH BANDS FROM BERYL
AFTER MID MORNING TODAY. CIGS MVFR AT TIMES WITH SHOWER BANDS
DURING THE AFTERNOON. DEEPER MOISTURE ARRIVES THIS EVENING AND WE
PREVAILED SOME SHOWERS BUT OVERALL RAINS SHOULD NOT BE STEADY.
KSAV...OVERNIGHT VFR CONDITIONS WILL GIVE WAY TO MVFR CIGS BEFORE
DAYBREAK AS MOISTURE INCREASES AHEAD OF THE SUBTROPICAL SYSTEM.
BASED ON THE LATEST OFFICIAL FORECAST TRACK OF BERYL...WE HAVE
MAINTAINED WINDS NEARING TROPICAL STORM STRENGTH IN GUSTS THIS
AFTERNOON ESPECIALLY IN CONSIDERATION TO THE DIURNAL EFFECTS WHICH
ALREADY FAVOR HIGHER GUSTS DURING THESE HOURS WITH SYNOPTIC ENE
FLOW. WE PREVAILED SHOWERS IN THE LATTER PORTION OF THE TAF CYCLE
ON SUNDAY AS WELL WITH CIGS MVFR AT TIMES. RAINS SHOULD BECOME
STEADIER AND HEAVIER AS DEEP MOIST CONVERGENCE INCREASES IN THE
LAST 6 HOURS OF THIS TAF CYCLE. EXPECTED SOLID MVFR CONDITIONS
WITH A CHANCE OF IFR CONDITIONS.
EXTENDED AVIATION OUTLOOK...SUB-VFR CONDITIONS REMAIN LIKELY
INTO EARLY NEXT WEEK...AS RAINFALL CHANCES FAIRLY DECENT WITH LOW
PRES IN THE REGION.
&&
.MARINE...
TONIGHT...TROPICAL STORM WARNINGS REMAIN IN EFFECT FOR THE ENTIRE
MARINE AREA OUTSIDE CHARLESTON HARBOR WHERE A WATCH HAS BEEN
REPLACED WITH A SMALL CRAFT ADVISORY. MARINERS ARE URGED TO
REMAIN IN PORT THROUGH THE MEMORIAL DAY WEEKEND...ESPECIALLY SOUTH
OF CHARLESTON. WINDS AND SEAS WILL STEADILY INCREASE TONIGHT AS
SUBTROPICAL STORM BERYL MOVES SOUTHWEST JUST EAST OF THE LOCAL
WATERS. INCREASING WINDS AND SWELL WILL DRIVE UP SIGNIFICANT WAVE
HEIGHTS TO AROUND 9-13 FT BEYOND 20 NM FROM THE COAST...HIGHEST
EAST. TROPICAL STORM FORCE WINDS ARE LIKELY BEYOND 20 NM BY
DAYBREAK WITH AT LEAST TROPICAL STORM FORCE GUSTS WITHIN 20 NM.
SUNDAY AND SUNDAY NIGHT...TREACHEROUS MARINE CONDITIONS WILL
IMPACT WATERS...WITH THE CLOSE PROXIMITY TO BERYL AS THE CENTER
PASSES NOT FAR TO THE SOUTH OR THE GA WATERS. TROPICAL STORM FORCE
WINDS WILL AFFECT THE SOUTHERN SC WATERS OUT 20 NM AND THE GA WATERS
OUT 60 NM DURING THIS PERIOD...WHILE THE CHARLESTON COUNTY WATERS
INCLUDING CHARLESTON HARBOR WILL GENERATE AT LEAST STRONG SCA
CONDITIONS. SEAS WILL REACH AS HIGH AS 7-9 FT NORTHERN WATERS...8-10
FT CENTRAL WATERS...9-12 FT SOUTHERN WATERS OUT 20 NM...BUT UP TO
12-18 FT 20-60 NM OFF THE GA COAST. EVEN CHARLESTON HARBOR WILL
EXPERIENCE WAVES OF 2-3 FT.
MONDAY AND MONDAY NIGHT...CONDITIONS WILL STEADILY IMPROVE AS BERYL
MOVES INLAND OVER NORTHERN FLORIDA AND SOUTHERN GEORGIA. ALTHOUGH
ONCE THE TROPICAL HEADLINES COME DOWN WE/LL STILL LIKELY REQUIRE AT
LEAST SCA HEADLINES FOR OUR GA WATERS.
TUESDAY AND TUESDAY NIGHT...BERYL WILL RE-CURVE BACK TOWARD THE NE
AND SHE MAY BE ABLE TO GAIN SOME STRENGTH AGAIN AS THE SYSTEM
RE-EMERGES OFF THE SE COAST. THE QUESTION IS WILL IT BE ABLE TO
REACH TROPICAL STORM STRENGTH...OR WILL STRONG SCA/S SUFFICE. WE CAN
ADDRESS THIS IN LATER FORECAST CYCLES. BUT WINDS AND SEAS WILL BE ON
THE INCREASE YET AGAIN.
WEDNESDAY THROUGH THURSDAY...PROVIDED THAT BERYL BEHAVES AS
EXPECTED...SHE LOOKS TO BE OUT OF THE FORECAST AREA BY
THURSDAY....AS WEAK ATLANTIC HIGH PRESSURE WILL BUILD IN HER WAKE.
LINGERING SCA OR POSSIBLE TROPICAL HEADLINES WEDNESDAY WILL FINALLY
COME DOWN BY THURSDAY AS CONDITIONS SHOULD IMPROVE THEN.
&&
.HYDROLOGY...
THE POTENTIAL FOR HEAVY RAINS WILL INCREASE ACROSS MAINLY
SOUTHEAST GEORGIA AND POSSIBLY FAR SOUTHERN SOUTH CAROLINA SUNDAY
INTO SUNDAY NIGHT AS BERYL PUSHES TO THE SOUTH AND SOUTHWEST
TOWARDS THE FLORIDA/GEORGIA BORDER. THE STRONG ONSHORE/CYCLONIC FLOW
COUPLED WITH INCREASING COASTAL CONVERGENCE AND PWATS AT OR ABOVE
2 INCHES /2 STANDARD DEVIATIONS ABOVE CLIMO FOR LATE MAY/ WILL
SUPPORT A RISK FOR HEAVY RAINFALL...MAINLY SUNDAY THROUGH AT LEAST
MONDAY.
BASED ON THE LATEST FORECAST FOR BERYL...WE/RE LOOKING AT THE
POSSIBILITY OF 2-4 INCHES OF RAIN INTO EARLY THIS UPCOMING WEEK. THE
BEST POTENTIAL VORTICITY AND THE STRONGEST LOW LEVEL MOISTURE
TRANSPORT IS TO BE SITUATED ACROSS SE GA...MAINLY SOUTH OF I-16. IT
IS THESE AREAS THAT CURRENTLY HAVE THE BEST CHANCE FOR FLOODING
RAINS...ESPECIALLY WITH ELEVATED TIDES THAT MAY INCREASE THE RISK
FOR FRESH WATER FLOODING ALONG THE COASTAL COUNTIES. THE EVENTUAL
TRACK BERYL TAKES WILL ULTIMATELY DEFINE WHERE THE AXIS OF HEAVIEST
RAINS WILL SETUP AND A FLASH FLOOD WATCH MAY EVENTUALLY BE NEEDED
FOR PARTS OF THE DROUGHT-STRICKEN AREA AS THESE DETAILS BECOME MORE
APPARENT. FOR NOW...WITH THE STRONGEST 850-300 MB BULK SHEAR
FORECAST FROM THE NW...WHICH WOULD DISTORT THE HEAVIEST RAIN OUTSIDE
OUR FORECAST AREA...WE HAVE HELD OFF ON A FLASH FLOOD WATCH AT THIS
TIME.
