Area forecast discussion, Feb 16, 1:09 AM EST, 58 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
109 AM EST TUE FEB 16 2016

.SYNOPSIS...
LOW PRESSURE AND A TRAILING COLD FRONT WILL IMPACT THE REGION
TONIGHT INTO TUESDAY MORNING. HIGH PRESSURE WILL DOMINATE THE
WEATHER PATTERN FOR THE REMAINDER OF THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
THE COASTAL WARM FRONT HAS LIFTED THROUGH THE AREA. THE WARMER
AIR IS PROGRESSING NORTH/NW AND IN ITS WAKE TEMPS ARE AS HIGH AS
THE LOWER AND MIDDLE 60S...OR SOME 20-25F WARMER THAN LAST
EVENING.

CONVECTIVE RAINS WERE INCREASING AND CONGEALING THROUGH THE
FORECAST AREA AS UPPER FORCING FOR ASCENT STRENGTHENS AHEAD OF
THE UPPER DISTURBANCE. WIDESPREAD SHOWERS AND A FEW STRONGER
T-STORMS ARRIVING FROM THE WEST/SW. A FEW OF THESE STORMS
HAVE EXHIBITED WEAK ROTATION IN THE PAST HOUR TO THE WEST OF
I-95.

THE COLD FRONT ITSELF IS ALSO QUITE IMPRESSIVE WITH PLENTIFUL
LINEAR FORCING ALONG IT. A QLCS HAS BEEN EVIDENT ON RADAR ALL
EVENING AS IT MARCHED THROUGH CENTRAL/SOUTHERN ALABAMA AND NOW
INTO SOUTH GEORGIA. AS IS NORMALLY THE CASE THIS TIME OF
YEAR...SHEAR IS IN ABUNDANCE WHILE INSTABILITY IS LIMITED.

SRH VALUES ARE STILL FORECAST AS GREAT AS 400-600 M2/SEC2 DURING
THE OVERNIGHT AND LOW LEVEL WINDS WILL REACH AS HIGH AS 50-60 KT
IN ADVANCE OF THE COLD FRONT IN THE WARM SECTOR. WHILE SURFACE
BASED INSTABILITY SHOULD HOLD AT OR BELOW 250-300 J/KG...LAPSE
RATES AREN/T THAT IMPRESSIVE AND THE TIMING IS TYPICALLY
UNFAVORABLE...THE OVERALL ENVIRONMENT WILL STILL FAVOR LINE
SEGMENTS WITH THE POTENTIAL FOR SOME EMBEDDED LOW-TOPPED
SUPERCELL CHARACTERISTICS. DAMAGING WIND GUSTS WILL BE THE MAIN
THREAT...BUT THE SHEAR AND SRH ALSO DICTATE THAT STORMS WILL
ROTATE AND BRING THE POTENTIAL FOR ISOLATED TORNADOES.

TEMPS WILL HOLD FAIRLY STEADY THE FIRST PART OF THE NIGHT WHERE
THE WARM FRONT HAS CLEARED AND ACTUALLY RISE INTO THOSE VALUES
ALONG THE NW TIER ONCE THE FRONT PASSES THROUGH. AS DEEPER
CONVECTION MOVES IN OVERNIGHT TEMPS WILL ONLY DESCEND BACK INTO
THE MID OR UPPER 50S.

OUTSIDE OF CONVECTION WINDS WILL BE RATHER GUSTY WITH THE LOW
LEVEL JET OF 40-50 KT DIRECTLY OVERHEAD AND SOUTHERLY WINDS WILL
CLIMB AS HIGH AS 25-30 MPH OVER MUCH OF THE AREA NEAR AND EAST OF
I-95...EVEN A LITTLE HIGHER AT THE COAST. ELSEWHERE 20-25 MPH CAN
BE ANTICIPATED.

LAKE WINDS...SOUTHERLY WINDS WILL INCREASE OVER LAKE MOULTRIE AND
AROUND THE LAKE SHORES BY AROUND MIDNIGHT IN BETWEEN THE WARM
FRONT TO THE NORTH AND THE COLD FRONT TO THE WEST/SW. THEN WINDS
WILL VEER TO THE SW AS THE COLD FRONT CROSSES THE AREA AROUND
DAYBREAK. WINDS MAY GUST TO 25 KT OR HIGHER WITHIN PASSING
SHOWERS AND/OR THUNDERSTORMS...BUT CONSISTENT CONDITIONS ARE NOT
EXPECTED TO MEET LAKE WIND ADVISORY CRITERIA AT THIS TIME.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH THURSDAY/...
TUESDAY...A COLD FRONT LOCATED NEAR/ALONG THE SOUTHEAST COAST AT
DAYBREAK WILL QUICKLY EXIT OFFSHORE IN THE MORNING. DRIER AIR
WORKING INTO THE FORECAST AREA BEHIND THE DEPARTING FRONT WILL ALLOW
ANY LINGERING PRECIP TO DIMINISH. CLEARING SKIES AND DOWNSLOPE FLOW
WILL OFFSET ANY COLD ADVECTION WITH HIGHS EXPECTED TO REACH THE MID
TO UPPER 60S. TUESDAY NIGHT...A POTENT SHORTWAVE WILL SEND A WEAK
COLD FRONT THROUGH THE AREA. LACK OF SIGNIFICANT MOISTURE WILL KEEP
A DRY FORECAST IN PLACE. LOW TEMPERATURES WILL BE IN THE LOW/MID 40S.

WEDNESDAY INTO THURSDAY...SURFACE HIGH PRESSURE WILL BUILD IN FROM
THE NORTHWEST PROVIDING CLEAR SKIES AND DRY WEATHER. THE SURFACE
HIGH WILL DRIFT INTO THE NORTHEAST U.S. ON THURSDAY...VEERING WINDS
AROUND TO THE NORTH. THIS WILL KEEP TEMPERATURES A BIT COOLER ON
THURSDAY. HIGHS WEDNESDAY WILL REACH THE MID 60S...WHILE THURSDAY
HIGHS ARE LIMITED TO THE UPPER 50S/LOW 60S. LOWS WEDNESDAY NIGHT IN
THE UPPER 30S/LOW 40S.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
DRY HIGH PRESSURE WILL SHIFT OVER THE WESTERN ATLANTIC THIS
WEEKEND...RESULTING IN A WARMING TREND OVER THE SOUTHEASTERN UNITED
STATES. IN GENERAL...TEMPS SHOULD MODIFY INTO THE MIDDLE/UPPER 60S
ON FRIDAY AS AN ONSHORE WIND DEVELOPS...THEN WARM INTO THE LOWER 70S
SATURDAY THROUGH MONDAY AS A SOUTHWEST SFC FLOW OCCURS ALONG THE
WESTERN EDGE OF HIGH PRESSURE CENTERED OVER THE ATLANTIC. OVERNIGHT
LOWS WILL ALSO TREND WARMER THROUGH THE WEEKEND...STARTING OUT IN
THE LOWER/MIDDLE 40S THURSDAY NIGHT...THEN UPPER 40S/LOWER 50S THIS
WEEKEND AND EARLY NEXT WEEK.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
KCHS...A FEW TSTMS HAVE MOVED BY AND MAINLY SCATTERED SHOWERS
UNTIL STEADIER CONVECTIVE RAINS MOVE IN LATE. FEW CHANGES MADE
OVERNIGHT WITH MARGINAL LLWS AT TIMES UNTIL 09Z AND MVFR CIGS.
BRIEF IFR CIGS ARE POSSIBLE. TSTMS STILL REMAIN POSSIBLE LATER
TONIGHT BUT WILL LET RADAR TRENDS DICTATE.

KSAV...SOME SHOWERS HAVE RECENTLY IMPACTED THE TERMINAL AND
THE MAIN BATCH OF CONVECTIVE RAINS LOOK TO COME IN NEAR 08Z.
TSTMS AND LOCALIZED STRONGER CONVECTIVE WIND GUSTS ARE POSSIBLE.

A STRONG DRY SLOT WILL SHUT OFF THE PCPN WITH CLEARING SKIES
AFTER SUNRISE AT BOTH TERMINALS. VFR EXPECTED AFTER MID MORNING
THROUGH 06Z WEDNESDAY.

VFR WEATHER WILL RETURN DURING THE EARLY MORNING TUESDAY.

EXTENDED AVIATION OUTLOOK...VFR CONDITIONS WILL PREVAIL LATE
TUESDAY NIGHT THROUGH FRIDAY.

&&

.MARINE...
OVERNIGHT...THE COASTAL WARM FRONT HAS MOVED NORTH/NW OF THE
MARINE AREA. BEHIND THE WARM FRONT A SE AND SOUTH FLOW WILL
STRENGTHEN TO 20-25 KT AND GUSTY THROUGH THE NIGHT...AS SEAS CLIMB
AS GREAT AS 5 TO 8 OR EVEN 9 FT...AND GREATEST AROUND 20 NM OUT OF
THE MOUTH OF THE SANTEE RIVER AND NEAR 60 NM OFF THE GA COAST. A
STRONG UPSTREAM COLD FRONT WILL DRAW CLOSE TO THE WATERS BY
DAYBREAK TUESDAY AS WINDS BEGIN TO VEER TO THE SW BY 6 AM OR SO.
FOR MUCH OF THE NIGHT WE LOOK FOR SCATTERED TO NUMEROUS SHOWERS
AND A FEW T-STORMS. MARINERS ARE URGED TO STAY ALERT IF TRAVERSING
THE WATERS OVERNIGHT INTO EARLY TUESDAY FOR THE RISK OF DANGEROUS
CONDITIONS.

TUESDAY THROUGH SATURDAY...SMALL CRAFT ADVISORIES WILL BE ONGOING
ACROSS ALL WATERS AT THE START OF THE PERIOD. A COLD FRONT WILL
QUICKLY CROSS THROUGH THE WATERS TUESDAY MORNING...WITH CONDITIONS
IMPROVING IN ITS WAKE. THE SMALL CRAFT ADVISORIES WILL DROP AT
VARYING TIMES AS THIS OCCURS...WITH THE LAST BEING IN THE OUTER GA
WATERS WEDNESDAY AFTERNOON. SURFACE HIGH PRESSURE WILL BUILD IN MID-
WEEK AND PERSIST INTO THE WEEKEND. THIS WILL KEEP CONDITIONS FAIRLY
QUIET WITH WINDS GENERALLY LESS THAN 15 KNOTS AND SEAS 2-5
FEET...HIGHEST IN THE OUTER PORTIONS OF THE MARINE ZONES.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
