AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
609 AM EDT SUN APR 15 2007
.SHORT TERM /TODAY THROUGH MON/...COLD FRONT MOVING THRU CENTRAL GA
WILL MOVE INTO THE ATLC BY LATE MORNING OR VERY EARLY IN THE AFTN.
STILL LOOKING AT A SEVERE WEATHER RISK WITH THE PRE-FRONTAL SQUALL
LINE WHICH IS NOW APPROACHING OUR SW CWFA. WE ARE ACTUALLY STARTING
TO SEE A LITTLE MORE SURFACE BASED INSTABILITY AS THE SECOND ROUND
OF CONVECTION IS FAST APPROACHING THE REGION. THIS ALONG WITH STRONG
LLJ /40-50 KT AT 925 MB/...120 KT UPPER LEVEL JET...0-1KM HELICITY
OF 300-400 M2/SEC2 CONTINUES TO POINT TOWARD POTENTIAL FOR ANOTHER
ROUND OF SEVERE WEATHER THE NEXT FEW HOURS.
RAINFALL AMOUNTS HAVE NOT YET BEEN AS HIGH AS WE EARLIER
ANTICIPATED...BUT MOST AREAS WILL RECEIVE SOME ADDITIONAL WELCOMED
RAINS AND WILL CONTINUE TO CARRY HIGH POPS AND SEVERE WORDING IN THE
PUBLIC FCST. STRONG CAA WILL DEVELOP IN WAKE OF THE FRONT THIS
AFTN...AND TEMPS WILL ACTUALLY BEGIN TO FALL THROUGHOUT THE AFTN
HOURS.
COLD POOL ALOFT MOVING IN LATE IN THE DAY WITH 500 MB TEMPS LOWERING
TO BETWEEN MINUS 15 AND 20C ASSOCIATED WITH AMPLIFIED TROUGH. THIS
COULD SUPPORT SMALL POPS...BUT WET BULB ZERO LEVELS ACTUALLY LOOK
TOO LOW /LESS THAN 5-6K FT/ TO SUPPORT ANY HAIL. EVEN STRONGER CAA
WILL MOVE IN WITH THE PASSAGE OF THE TROUGH...AND WE ARE LOOKING AT
TEMPS TONIGHT FALLING INTO THE 30S ACROSS MANY INLAND LOCATIONS. NO
RECORDS...FROST OR FREEZE ARE EXPECTED...BUT I DID TWEAK A FEW TEMPS
DOWN WITH SOME OF THE CO-OP MOS GUIDANCE SHOWING LOWER-MID 30S.
MON WILL BE A SUNNIER DAY...BUT WITH DEEP MIXING PROFILES IT WILL
AGAIN BE WINDY/BREEZY. TEMPS WILL ONLY REACH THE 60S TO NEAR 70.
&&
.LONG TERM /MON NIGHT THRU SAT/...FEW IF ANY CHANGES THIS MORNING TO
THE EXTENDED FCST.
&&
.MARINE...06Z CHS SOUNDING INDICATED WINDS UP TO 45 KT AT 925 MB.
BOTH GFS AND NAM HANDLE THIS LOW LEVEL JET WELL...WHILE ALSO SHOWING
THE FEATURE INTENSIFYING TOWARD 12Z. TIMING DIFFERENCES BETWEEN THE
TWO MODELS ABOUND CONCERNING THE PASSAGE OF THE APPROACHING COLD
FRONT STILL HUNG TO THE WEST ACROSS CENTRAL GEORGIA. OBSERVATIONS
WITHIN 20 NM OF THE COAST HAVE NOT REPORTED SOUTHERLY WINDS ANY
STRONGER THAN SCA THRESHOLDS OVERNIGHT AND INTO THE MORNING.
DESPITE THE DELAYED WIND RESPONSE NEARSHORE...FEEL THAT THE
GRADUALLY INTENSIFYING LLJ WILL ENHANCE WINDS OVER THE WATERS
SHORTLY. CONFIDENCE IS FAIRLY HIGH THAT FOLLOWING THE COLD FRONTAL
PASSAGE LATER THIS MORNING...THE INITIATION OF COLD ADVECTION OVER
THE RELATIVELY WARMER WATERS WILL MAINTAIN GALE FORCE WINDS THROUGH
THIS EVENING BY TAPPING INTO THE LINGERING LOW LEVEL JET. STRONGEST
WINDS ARE EXPECTED TONIGHT...WHEN MAXIMUM MIXING OCCURS OVER THE
WATERS. THUS HAVE MADE LITTLE CHANGE TO THE ONGOING WIND FORECAST
FOR THE MARINE ZONES...KEEPING THE GALE WARNINGS CURRENTLY IN PLACE.
SEAS ARE BUILDING AS A RESULT OF THE STRONG SOUTHERLY WINDS THIS
MORNING AND ARE EXPECTED TO REACH 6 TO 9 FT NEARSHORE AND 9 TO 12 FT
IN THE OUTER WATERS. ALTHOUGH WINDS WILL BECOME OFFSHORE THIS
AFTERNOON BEHIND THE COLD FRONT...SEAS WILL BE SLOWER TO SUBSIDE.
WILL LIKELY NEED TO FOLLOW THE GALE WARNING WITH A SMALL CRAFT
ADVISORY MONDAY...AS THE STRONG LOW PRESSURE SYSTEM DEEPENS OFF THE
NEW ENGLAND COAST AND MAINTAIN A STRONG PRESSURE GRADIENT ACROSS THE
COASTAL WATERS.
MARINE CONDITIONS WILL BEGIN TO IMPROVE BY TUESDAY AS HIGH PRESSURE
BUILDS IN FROM THE WEST.
&&
.LAKE WINDS...HAVE CONTINUED THE LAKE WIND ADVISORY FOR LAKE
MOULTRIE THIS MORNING...AS WINDS UP TO 20 KT HAVE BEEN REPORTED.
EXPECT WINDS OVER ALL OF SOUTHEAST SC TO CONTINUE TO INCREASE LATER
IN THE MORNING AS DAYTIME MIXING TAPS INTO STRONG WINDS ALOFT.
THUS...A WIND ADVISORY HAS BEEN ISSUED FOR SOUTHEAST SOUTH CAROLINA
AFTER 8 AM EDT THIS MORNING...REPLACING THE LAKE WIND ADVISORY.
&&
.COASTAL HAZARDS...WILL CONTINUE TO MENTION THE RISK OF HIGH SURF
TODAY ALONG THE COAST OF SOUTHEAST SC AND GA THROUGH THIS
EVENING...AS SEAS WITHIN THE NEARSHORE WATERS INCREASE TO 6 TO 9 FT.
THESE ELEVATED SEAS WILL BE SLOW TO SUBSIDE TONIGHT...EVEN AFTER
WINDS BECOME OFFSHORE THIS AFTERNOON. ADDITIONALLY...BEACH EROSION
MAY BE LIKELY ALONG THE SOUTH CAROLINA BEACHES. TIDE LEVELS WILL
FALL SHORT OF ANY SHALLOW COASTAL FLOODING THIS MORNING.
&&
.RIP CURRENTS...THE COMBINATION OF THE UPCOMING PERIGEE AND NEW MOON
AND STRONG WSW WINDS WILL ENHANCE THE RISK OF RIP CURRENTS TODAY.
DESPITE LITTLE TO NO SWELL ACTIVITY...LOCAL RIP CURRENT ANALYSIS
PUTS THE AREA INTO MODERATE RISK FOR TODAY.
&&
.AVIATION /19Z-06Z/...CURRENT RADAR SHOWS WIDESPREAD
SHOWERS/THUNDERSTORMS MOVING INTO THE AREA AND SHOULD LAST INTO MID
MORNING. SURFACE WINDS WILL REMAIN GUSTY THROUGH THE TAF PERIOD
BUT WITH A LOW LEVEL JET ALOFT THIS WILL CAUSE A BIT OF SPEED SHEAR
AROUND 2 KFT AT BOTH TERMINALS THROUGH 17Z. EXPECT MOSTLY MVFR
CONDITIONS ALTHOUGH WORSE CONDITIONS ARE POSSIBLE ESPECIALLY IN A
SHOWER OR THUNDERSTORM. WILL KEEP MONITORING THE SITUATION AS THESE
SHOWERS TEND TO BE BROKEN AND WILL AMEND IF/WHEN NECESSARY.
&&
.FIRE WEATHER...GUSTY WINDS WILL BE OF CONCERN TODAY...BUT HUMIDITY
LEVELS WILL NOT FALL MUCH BELOW 50 TO 55 PERCENT. HOWEVER...MIXING
HEIGHTS REACH 6-8K FT MON...WHICH WILL TAP INTO MOST OF THE 30-40 KT
WINDS AND VERY DRY AIR IN THIS LAYER. AS A RESULT WE ARE LOOKING AT
POSSIBLE RED FLAG CONDITIONS. LATER SHIFTS WILL NEED TO CONTACT
USERS TO SEE IF A WATCH OR WARNING IS NECESSARY. CRITICAL RH WILL
AGAIN OCCUR TUE...BUT WITH LESS WIND.
