AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
1250 AM EST SUN MAR 1 2009
.SYNOPSIS...
COMPLEX LOW PRESSURE WILL IMPACT THE REGION TONIGHT THROUGH MON.
HIGH PRESSURE WILL BUILD IN TUE THROUGH SAT.
&&
.NEAR TERM /UNTIL 6 AM THIS MORNING/...
WATER VAPOR IMAGERY CLEARLY SHOWS AN ANOMALOUSLY STRONG UPPER LOW
DIGGING THROUGH SOUTHERN ARKANSAS WITH WHAT APPEARS TO BE AN
IMPRESSIVE DEFORMATION BAND DEVELOPING ALONG THE NORTH SIDE OF
THE LOW CENTER. AT THE SURFACE...LOW PRESSURE ACROSS THE MIDLANDS
IS SHOWING SIGNS OF REFORMING ACROSS THE CSRA WITH A WARM FRONT
EXTENDING EAST/NORTHEAST THROUGH THE NORTHERN MIDLANDS INTO
SOUTHEAST NORTH CAROLINA AND A TRAILING COLD FRONT EXTENDING
THROUGH SOUTHWEST GEORGIA AND INTO THE CENTRAL GULF OF MEXICO.
THE 18Z MODELS AND THE INCOMING 00Z NAM CONTINUE TO SUPPORT THE
SURFACE LOW CONSOLIDATING ACROSS EAST-CENTRAL GEORGIA AND THE CSRA
OVERNIGHT AS Q-G FORCING AHEAD OF THE UPPER LOW OVERSPREADS THE
SOUTHEAST UNITED STATES. THE MAIN FORECAST CHALLENGE FOR TONIGHT
IS PINNING DOWN THE SEVERE WEATHER POTENTIAL AS WELL AS LOWS
SUNDAY MORNING.
LINES OF SHOWERS AND TSTMS CONTINUE TO REDEVELOP ACROSS PORTIONS OF
SOUTHWEST GEORGIA AND THE FLORIDA PANHANDLE WHERE LOW-LEVEL
INSTABILITY IS MAXIMIZED. EXPECT THIS ACTIVITY TO EXPAND NORTHEAST
INTO THE REGION LATER TONIGHT AS THE EASTERN MOST CORE OF STRONGEST
UVM MOVES IN FROM THE WEST. WILL MAINTAIN CATEGORICAL POPS FOR ALL
AREAS TONIGHT. THE RISK FOR LARGE HAIL...DAMAGING WINDS AND
TORNADOES PERSISTS WITH THE GREATEST NEAR TERM RISK HOLDING SOUTH OF
I-16 WHERE A TORNADO WATCH CONTINUES UNTIL 3 AM. WE MAY VERY HAVE TO
EXPAND THE TORNADO WATCH FARTHER TO THE NORTH INTO PORTIONS OF
SOUTHERN SOUTH CAROLINA LATER TONIGHT AS LOW-LEVEL INSTABILITY AND
0-1KM HELICITIES INCREASE AHEAD OF THE SURFACE LOW. WILL KEEP
MENTION OF SEVERE WEATHER FOR MOST AREAS TONIGHT WITH LARGE
HAIL...DAMAGING WINDS AND TORNADOES BEING THE PRIMARY HAZARDS.
RAINFALL AMOUNTS OF 1-3 INCHES MAY ALSO PRODUCE SOME AREAS OF
FLOODING...MAINLY IN LOW-LYING AND POOR DRAINAGE AREAS.
WITH THE POSITION OF THE SURFACE LOW EXPECTED TO REMAIN ACROSS THE
FAR WESTERN PORTIONS OF THE FORECAST AREA...SOME FAIRLY SIGNIFICANT
ADJUSTMENTS TO OVERNIGHT LOWS HAD TO BE MADE EARLIER THIS EVENING.
TEMPERATURES SHOULD CONTINUE TO HOLD OR SLOWLY RISE FOR THE NEXT
FEW HOURS BEFORE LEVELING OFF OR SLOWLY DROPPING LATE AS SHOWERS
AND TSTMS MOVE IN FROM THE SOUTHWEST. ADDITIONAL ADJUSTMENTS TO
SUNDAY/S HIGH TEMPERATURES ARE ALSO NEEDED WITH THE WARMEST
READINGS LIKELY OCCURRING AN HOUR OR TWO AFTER SUNRISE...WITH
TEMPERATURES FALLING THEREAFTER AS THE SURFACE LOW PULLS AWAY.
WE CONTINUE TO CAREFULLY MONITOR THE POTENTIAL FOR ACCUMULATING
SNOWS ACROSS THE AREA LATE SUNDAY AFTERNOON INTO MONDAY MORNING.
THE 00Z NAM HAS TRENDED A BIT FARTHER SOUTH WITH THE TRACK OF THE
UPPER LOW FROM ITS PREVIOUS RUN AND IS SHOWING 1-3 INCHES OF SNOW
FROM ALLENDALE COUNTY UP THROUGH BERKELEY COUNTY. EVEN THE 00Z NGM
MOS IS FORECASTING AN INCH AT CHS AND 2 INCHES AT NBC. THERE IS
STILL TREMENDOUS UNCERTAINTY WITH THIS SYSTEM AND IT WILL BE
INTERESTING TO SEE HOW THE 00Z ECMWF AND GFS TREND. ADDITIONAL
REFINEMENTS TO THE SNOW FORECAST WILL BE MADE LATER TONIGHT.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/...
AN ACTIVE REGIME WILL CONTINUE SUNDAY. TO START...THE THREAT FOR
STRONG/SEVERE THUNDERSTORMS WILL PERSIST THROUGH THE MORNING...EARLY
NEAR THE COAST BEFORE THE WARM SECTOR IS SHUNTED OFF THE COAST...BUT
PRIMARILY FROM A BAND OF CONVECTION THAT MAY DEVELOP AHEAD OF THE
UPPER LOW/COLD POOL AND ASSOCIATED MID LEVEL DRY SLOT. THE PRIMARY
SEVERE THREAT SHOULD BE HAIL...BUT ISOLATED DAMAGING WIND GUSTS
CANNOT BE RULED OUT. THIS THREAT IS ADDRESSED WITHIN THE HAZARDOUS
WEATHER OUTLOOK.
SUNDAY AFTERNOON...SURFACE TEMPERATURES SHOULD FALL ACROSS THE
REGION AS STRONG COLD ADVECTION GETS UNDERWAY. MEANWHILE...12Z
GUIDANCE...ESPECIALLY THE GFS...SUGGESTS THAT DEEP WRAP AROUND
MOISTURE WILL ROTATE THROUGH INLAND COUNTIES DURING THE 18Z-0Z TIME
FRAME. TRADITIONAL THICKNESS FORECASTS...INCLUDING 100-850 MB
THICKNESS...SUGGEST THAT THE ENVIRONMENT WILL BECOME COLD ENOUGH FOR
ALL SNOW MOST AREAS DURING THE AFTERNOON. HOWEVER...GFS/NAM MODEL
SOUNDINGS SUGGEST THAT FREEZING LEVELS WILL REMAIN TOO HIGH...AT
LEAST 2 KFT AGL...TO SUPPORT ANY SNOW. ACROSS FAR INLAND SC/GA
ZONES...THE COMBINATION OF DEEP WRAP AROUND MOISTURE...COLD
ADVECTION AND DEEP LAYER ASCENT/DYNAMIC COOLING COULD SUPPORT SOME
WET SNOW DURING THE AFTERNOON...A POTENTIAL SUFFICIENT TO JUSTIFY A
MENTION OF A CHANCE OF SNOW...WITH LITTLE/NO ACCUMULATION...TO
ACCOMPANY CATEGORICAL POPS FOR RAIN SHOWERS DURING THE AFTERNOON.
NO WINTER HEADLINES ARE JUSTIFIED AT THIS TIME.
&&
.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
SUN NIGHT THROUGH MON NIGHT WILL BE THE MOST COMPLICATED PART OF THE
EXTENDED FORECAST AND HENCE THE PORTION WITH THE SHAKIEST CONFIDENCE
WHILE TUESDAY THROUGH THE REST OF THE WEEK HAS FAIRLY HIGH
CONFIDENCE WITH THE LACK OF ANY SIGNIFICANT WX SYSTEMS.
SUN NIGHT...PRIMARY SFC LOW PRES CENTER LOOKS TO BE CENTERED OFF THE
NC OUTER BANKS WITH A WEAKER SECONDARY SFC LOW OVER ERN SC.
MEANWHILE...THE POTENT DEEP UPPER LEVEL LOW WILL BE DISPLACED OVER
SRN SC AT THE START OF THE PERIOD. BOTH SYSTEMS LOOK TO MOVE IN
TANDEM TO THE NE THROUGH THE NIGHTTIME PERIOD. MOISTURE DEPTH IS
STILL ENOUGH TO PRODUCE 0.75-1.25 INCH PWATS BUT THE CONCERN IS THAT
THE MAJORITY OF THE MOISTURE IS WITHIN THE LOWEST LEVELS OF THE
ATMOS...MEANING THAT THE LAYER ARND -10 DEG C WILL BE WELL DEVOID OF
ENOUGH MOISTURE FOR GOOD CRYSTAL GROWTH TO PRODUCE ANY SIGNIFICANT
SNOWFALL THROUGH THE OVERNIGHT PERIOD. THAT BEING SAID...BUFKIT
SOUNDINGS DEPICT TEMP PROFILES AND TIMING TO ALLOW FOR FREEZING
TEMPS TO BE REACHED WITHIN A DEEP ENOUGH AREA TO ALLOW FOR ONGOING
RAINFALL TO MIX WITH AND CHANGE OVER TO SNOW FOR THE ENTIRE AREA
/ASIDE FROM THE IMMEDIATE SHORELINE/ BY 06Z MON. THERE IS THE
CONCERN THAT IF ENOUGH DRY SLOTTING OCCURS PER 12Z NAM PROGS THAT
THE PRECIP COULD BE MORE OF A DRIZZLE-TO-FLURRIES REGIME RATHER THAN
A RAIN-TO-SNOW REGIME. HOWEVER...CONSIDERING THAT THE CONSENSUS
AMONG NATIONAL GUIDANCE IS TO USE THE 12Z GFS...HAVE OPTED TO GO
THAT ROUTE WHICH BRINGS ENOUGH QPF IN AN 8-TO-1 RATIO TO PRODUCE UP
TO A HALF INCH OF SNOW ALONG THE FAR NRN FRINGES OF THE CHS CWFA.
WILL LOOK FOR MIN TEMPS TO DROP TO THE UPR 20S TO LWR 30S AWAY FROM
THE COAST WITH LOW-MID 30S CLOSER TO SHORE.
MON...UPPER LOW WILL BE LOCATED OVER NC/VA BY DAYBREAK MON WHILE THE
SFC LOW IS WELL NE OF THE AREA...OFF THE SRN NEW ENGLAND COAST. THIS
WILL ALLOW FOR A DEEP DRY NWLY FLOW TO TAKE HOLD OVER THE AREA.
ALTHOUGH A FEW LINGERING RAIN/SHOW SHOWERS ARE POSSIBLE AT THE
OUTSET OVER FAR NRN PORTIONS OF THE CHS CWFA...THE PREDOMINANT
THINKING IS THAT MOISTURE WILL BE SCOURED OUT FROM W TO E AS HIGH
PRES BEGINS TO MAKE INROADS TO THE AREA. WITH COLD AIR ADVECTION
WELL UNDERWAY...MAX TEMPS ON MON WILL GENERALLY HOLD IN THE 40S AND
IT IS NOT UNREASONABLE THAT FAR NRN PORTIONS OF THE AREA COULD STAY
IN THE UPPER 30S.
MON NIGHT...SKIES WILL CONTINUE TO CLEAR OUT AS HIGH PRES PROGRESSES
INTO THE AREA. HOWEVER...WITH THE PRESSURE GRADIENT NOW QUITE LAYING
DOWN BETWEEN THE INCOMING HIGH AND OUTGOING COMPLEX SYSTEM...WIND
CHILLS IN THE TEENS CAN BE EXPECTED FOR MANY AREAS WEST OF
INTERSTATE 95 AS LOWS DROP TO THE LOW-MID 20S. E OF I-95...LOWS WILL
DROP GENERALLY TO THE MID-UPR 20S WITH WIND CHILLS AROUND 20.
TUE-FRI...HIGH PRES WILL BE THE PREDOMINANT WX FEATURE THROUGH THE
REMAINDER OF THE WEEK AS IT SLOWLY MOVES E THROUGH THE SE STATES AND
SETTLES IN THE WRN ATLC. THERE LOOKS TO BE A FEW STREAKS OF MOISTURE
IN THE UPPER LEVELS TUE-WED THAT WILL MAKE FOR A MORE PESSIMISTIC
CLOUD COVER FCST BUT THE LACK OF DEEP MOISTURE AND LIFTING
MECHANISMS WILL MAKE FOR A DRY FCST THROUGHOUT. TEMPS WILL GRADUALLY
WARM BACK TO NEAR AND EVEN ABOVE NORMAL LEVELS BY THE END OF THE
WEEK.
&&
.AVIATION /06Z SUNDAY THROUGH THURSDAY/...
CONDITIONS WILL DETERIORATE RATHER QUICKLY EARLY THIS MORNING WITH
A SURFACE LOW PRESSURE SYSTEM MOVING TOWARD THE COAST FROM THE
NORTHWEST. RAIN SHOWERS WITH EMBEDDED TSTMS WILL INCREASE IN
COVERAGE AND INTENSITY THROUGH MID-MORNING. MVFR TO IFR CEILINGS
AND VSBYS WILL DOMINATE THROUGH MUCH OF THE NEXT 24 HRS. INCLUDED
A TEMPO WITH SOME HEAVY RAIN AND 2SM VSBY AT CHS DURING THE MID-
MORNING HOURS. MUCH OF THE MODEL GUIDANCE CONTINUES TO INDICATE A
STRONG AREA OF DEEP FORCING WILL SHIFT THROUGH THE CHS AREA AHEAD
OF THE MAIN LOW PRESSURE SYSTEM DURING THAT TIME. WINDS WILL SWING
AROUND TO WEST AND NORTHWEST DURING THE EARLY AFTERNOON AS MUCH
COOLER AIR SHIFTS IN. GUSTY CONDITIONS ANTICIPATED THROUGH TONIGHT
WITH THE STRONG COLD AIR MOVING IN.
EXTENDED AVIATION OUTLOOK...GUSTY NORTH WINDS EXPECTED TO CONTINUE
LATE TONIGHT INTO MON. AT THIS TIME WE ARE NOT EXPECTING
ACCUMULATING SNOWFALL AT EITHER AIRPORT TONIGHT INTO MON MORNING.
VFR CONDITIONS RETURN MON AND LAST THROUGH MIDWEEK AS HIGH
PRESSURE MOVES IN FROM THE NW.
&&
.MARINE...
WILL CANCEL FLAGS FOR THE CHARLESTON HARBOR A LITTLE EARLY.
OTHERWISE THE CURRENT FORECAST LOOKS GOOD. NO MAJOR CHANGES ARE
NEEDED.
SMALL CRAFT ADVISORY WINDS/SEAS WILL PERSIST MUCH OF THE TIME
THROUGH SUNDAY...ALTHOUGH A BRIEF LULL IN WINDS COULD DEVELOP AS
THE SURFACE LOW ADVANCES INTO THE COASTAL WATERS SUNDAY.
FOR SUN NIGHT THROUGH MON NIGHT...STRONG NW WINDS WILL PERSIST OVER
ALL MARINE ZONES AS A POTENT UPPER LEVEL STORM SYSTEM MOVES OVER AND
THROUGH THE WATERS. STRONG COLD AIR ADVECTION OVER THE WATERS...
PARTICULARLY OUT NEAR THE GULF STREAM WHERE SHELF WATERS ARE
WARMEST...LOOKS TO ALLOW FOR GOOD MIXING WHERE FREQUENT GUSTS TO
GALE FORCE ARE POSSIBLE. THUS...HAVE OPTED TO RAISE A GALE WATCH FOR
THE OUTER GA WATERS WHILE ALL NEARSHORE ZONES SHOULD REMAIN WITHIN
SOLID SCA CONDITIONS. BY LATE MON INTO MON NIGHT...HIGH PRES WILL
MAKE GOOD PROGRESSION INTO THE AREA SUCH THAT CONDITIONS WILL BE
IMPROVING DURING THIS PERIOD. HIGH PRESSURE WILL THEN SETTLE INTO
THE ATLC STARTING TUE...LASTING THROUGH THE REST OF THE WEEK...
MAKING FOR BENIGN CONDITIONS FOR THE MID-TO-LATE WEEK PERIOD.
