Area forecast discussion, Jun 11, 2:05 PM EDT, 3 hours 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
205 PM EDT WED JUN 11 2014

.SYNOPSIS...
EXPECT INCREASED RAIN CHANCES AS AN UPPER TROUGH APPROACHES THE
REGION FROM THE WEST...AND ATMOSPHERIC MOISTURE INCREASES. WEAK
UPPER TROUGHINESS AND SUFFICIENT ATMOSPHERIC MOISTURE WILL PROVIDE
CONTINUED CHANCES OF MAINLY AFTERNOON AND EVENING THUNDERSTORMS
THROUGH EARLY NEXT WEEK...WITH NEAR NORMAL TEMPERATURES.

&&

.NEAR TERM /THROUGH TONIGHT/...
MOISTURE HAS BEEN INCREASING THROUGH THE MORNING AND SHOWERS AND
THUNDERSTORMS HAVE DEVELOPED OVER THE WESTERN PART OF THE CWA AS
OF 17Z. EXPECT THIS TREND TO CONTINUE THROUGH THE AFTERNOON INTO
THE EARLY EVENING WITH SHOWER AND THUNDERSTORM ACTIVITY
OVERSPREADING MOST OF THE CWA. CURRENTLY HAVE POPS IN THE 50 TO
60 PERCENT RANGE. MAY HAVE TO INCREASE THESE TO ACCOUNT FOR LINEAR
CONVECTION MOVING EAST ACROSS THE AREA.

SEVERE PARAMETERS HAVE BECOME MORE FAVORABLE FOR SEVERE WEATHER
THAN WAS ORIGINALLY FORECAST BY THE MODELS WITH SB LI/S IN THE -6
TO -7 RANGE AND THE CRAVEN/BROOKS SIG SEVERE PARAMETER IN THE
20000 TO 30000 RANGE JUST AHEAD OF THE DEVELOPING LINE. MAIN
THREAT WILL BE WINDS. ALSO WITH PW VALUES GREATER THAN 1.8 IN AND
SOME TRAINING OCCURRING...LOCALIZED FLOODING IS POSSIBLE. HI-RES
MODELS HAVE CONVECTION DISSIPATING AFTER 00Z WITH ONLY SCT TO
WIDELY SCATTERED SHOWERS OR THUNDERSTORMS THROUGH THE REMAINDER OF
THE NIGHT.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
THE MAIN UPPER LOW CONTINUES TO WEAKEN AND MOVE EASTWARD TOWARDS
THE REGION THURSDAY INTO FRIDAY. THE MAIN TROUGH MOVES EAST
FRIDAY...BUT WILL QUICKLY BE REPLACE WITH A SECOND TROUGH DROPPING
INTO THE REGION. THIS WILL CONTINUE TO KEEP UNSETTLED CONDITIONS
IN THE FORECAST. THERE SHOULD STILL BE ENOUGH LOW-LEVEL MOISTURE
AND INSTABILITY IN THE AFTERNOON HOURS TO PRODUCE AT LEAST
SCATTERED SHOWERS AND THUNDERSTORMS BOTH DAYS. ACTIVITY SHOULD
DIMINISH LATE IN THE EVENING HOURS. AFTERNOON HIGHS THURSDAY
ADVERTISED TO BE A FEW DEGREES COOLER UNDER THE UPPER LOW...MAINLY
DUE TO THE INCREASE IN CLOUD COVER ASSOCIATED WITH THE LOW. TEMPS
THURSDAY IN THE MIDDLE TO UPPER 80S. FOR FRIDAY READINGS SHOULD
ONCE AGAIN BE ABLE TO CLIMB TO AROUND 90. OVERNIGHT LOWS FALLING
INTO THE MIDDLE TO UPPER 60S BOTH NIGHTS.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
LONGER RANGE MODELS NOW SHOWING THE REGION SANDWICHED BETWEEN
UPPER RIDGING OFF THE SOUTHEASTERN COAST AND WEAK RIDGING ACROSS
THE SOUTHERN MISSISSIPPI VALLEY. THIS KEEPS A WEAK UPPER TROUGH
OVER THE AREA INTO THE FIRST PART OF NEXT WEEK. BY MID-
WEEK...DEEPER TROUGH TAKES HOLD IN THE WESTERN STATES...HELPING TO
BUILD A WEAK RIDGE ACROSS THE EAST. STILL MUCH UNCERTAINTY WITH
POPS THROUGH THE PERIOD. WOULD EXPECT TYPICALLY SUMMER PATTERN OF
DIURNAL CONVECTION. NEAR CLIMO TEMPS.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE CWA THIS AFTERNOON.
HAVE TEMPO MVFR IN TAFS AT AGS AND DNL BETWEEN 18Z AND 22Z AND
BETWEEN 20Z AND 00Z AT OGB...CAE...AND DNL. IT IS POSSIBLE THAT
VIS WILL VERY BRIEFLY GO TO IFR IN RAIN CORES THAT MOVE OVER THE
TERMINAL BUT DID NOT GO THIS LOW IN THE TAF. CONVECTION WILL
DISSIPATE AFTER 00Z WITH ONLY WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS EXPECTED DURING THE REMAINDER OF THE OVERNIGHT
HOURS. HOWEVER...WITH INCREASED SURFACE MOISTURE DUE TO THE
RAINFALL...FOG MAY BECOME AN ISSUE FROM AROUND 09Z THROUGH 13Z.
WILL HAVE TO MONITOR WHERE THE RAIN FALLS AND HOW SKY CONDITIONS
EVOLVE OVERNIGHT. THE 00Z AND 06Z TAF ISSUANCE SHOULD HAVE A
BETTER HANDLE ON THIS POSSIBILITY.

WIND WILL GENERALLY BE FROM THE SOUTH TO SOUTHWEST AT 10KTS OR
LESS THROUGH THE PERIOD EXCEPT FOR HIGHER WIND SPEEDS AND GUSTS IN
THUNDERSTORMS.

EXTENDED AVIATION OUTLOOK...SCATTERED THUNDERSTORMS EACH DAY MAY
CAUSE BRIEF MVFR CIGS/VSBYS.

&&

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