Area forecast discussion, Jan 11, 2:00 PM EST, 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
200 PM EST SAT JAN 11 2014

.SYNOPSIS...
HIGH PRESSURE WILL BUILD INTO THE REGION BEHIND A COLD FRONT TONIGHT
INTO SUNDAY. ANOTHER COLD FRONT WILL APPROACH FROM THE WEST MONDAY
NIGHT.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
LATEST RADAR RETURNS SHOWS A LINE OF STRONG TO SEVERE CONVECTION
OVER THE FORECAST AREA WELL AHEAD OF SURFACE COLD FRONT CURRENTLY
PUSHING ACROSS GEORGIA. SPC WRF MODEL QUICKLY MOVES PRECIPITATION
EAST THIS AFTERNOON AND EARLY EVENING WITH MOST OF THE FORECAST
AREA CLEAR OF ANY SEVERE WEATHER THREAT AFTER SUNSET. A FAIRLY
LARGE RAIN SHIELD BEHIND THE LEADING EDGE OF STRONGER CONVECTION
IS PRODUCING 88D ESTIMATED 3 HOUR TOTALS OF 1-2 INCHES OR MORE IN WESTERN
AREAS OF THE FORECAST AREA. LOCALIZED FLOODING NOT OUT OF THE
QUESTION THIS AFTERNOON. MAIN CONCERN HOWEVER CONTINUES TO BE
DAMAGING WIND GUSTS WITH A STRONG LOW LEVEL JET AND ALSO THE
POTENTIAL FOR A FEW TORNADOES AS SUPPORTED BY FORECAST HODOGRAPHS.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
DRYING AND CLEARING SKIES WILL OCCUR BEHIND THE FRONT
TONIGHT WITH RAIN CHANCES DECREASING RAPIDLY FROM WEST TO EAST THIS
EVENING. DRY WEATHER THROUGH THE PERIOD WITH HIGH PRESSURE BUILDING
OVER THE REGION SUNDAY...DRIFTING OFF THE COAST LATE MONDAY. MODELS
SIMILAR WITH TEMPERATURES A LITTLE WARMER THAN NORMAL THROUGH THE
PERIOD.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
LONGER TERM MODELS SHOW PROGRESSIVE PATTERN WITH SERIES OF UPPER
LEVEL TROFS MOVING ACROSS THE FORECAST AREA BY MID WEEK AND AGAIN
BY FRIDAY...BRIEF RIDGING THURSDAY. GOING CHANCE POPS CAN BE
ADJUSTED FOR TIMING AND INTENSITY BUT THE TREND LOOKS GOOD AT THE
MOMENT. AVAILABLE MOISTURE WITH THESE SYSTEMS STILL IN QUESTION.
GFSX AND ECMX MOS GUIDANCE MAINLY A LITTLE COOLER THAN NORMAL
THROUGH THE PERIOD.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/... COLD FRONT CONTINUES TO
MARCH ACROSS THE SOUTHEAST WITH WSR-88D NETWORK SHOWING SHOWERS
AND THUNDERSTORMS MOVING ACROSS SC/GA THIS AFTERNOON. A FEW OF
THESE STORMS HAVE AND WILL BE STRONG THROUGH THE AFTERNOON. EXPECT
PERIODS OF MAINLY MVFR ACROSS THE CWA THIS AFTERNOON...BUT AS
STORMS MOVE ACROSS TAF SITES CONDITIONS COULD DETERIORATE DOWN TO
LIFR/IFR. WINDS WILL BE GUSTY FROM THE SOUTH THIS AFTERNOON THEN
SHIFT TO THE SW AND WEST TONIGHT INTO SUNDAY. EXPECT WINDS TO BE
AROUND 15 KTS WITH GUSTS UP TO 25 KTS THROUGH THE AFTERNOON...THEN
DIMINISHING SOME THROUGH THE NIGHT. FRONT WILL MOVE OFFSHORE THIS
EVENING WITH DRIER AIR BEGINNING TO MOVE IN WITH CONDITIONS
RETURNING TO VFR BETWEEN 01Z AND 02Z.

EXTENDED AVIATION OUTLOOK...RESTRICTIONS POSSIBLE MONDAY NIGHT
THROUGH TUESDAY MORNING IN SHOWERS ASSOCIATED WITH THE NEXT COLD
FRONT.

&&

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