AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE COLUMBIA SC
332 AM EDT SAT JUL 13 2013
.SYNOPSIS...
HIGH PRESSURE OFF THE EASTERN SEABOARD CONTINUES TO PUSH VERY
MOIST AIR INTO THE AREA WITH A FRONT CURRENTLY STALLED NEAR THE
COAST. THE FRONT WILL REMAIN OVER THE AREA THROUGH SATURDAY AND BE
THE FOCUS FOR ADDITIONAL HEAVY RAINFALL INTO THE WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
THE STALLED FRONTAL BOUNDARY...MAINLY A DEWPOINT GRADIENT...WILL
BEGIN TO MOVE WESTWARD LATER TODAY AND TONIGHT. WV LOOP THIS
MORNING SHOWS THE CLOSED LOW ACROSS THE OH RIVER VALLEY DRIFTING
SOUTHWEST TOWARD THE TN VALLEY THIS MORNING. CLOSED AREA OF HIGH
PRESSURE OFF THE MID ATLANTIC COAST AND REMNANTS OF UPPER LOW IN
THE EASTERN GULF OF MEXICO CONTINUE TO ROTATE MOISTURE UP AND INTO
THE SOUTHEAST. REGIONAL 88D RADAR COMPOSITE THIS MORNING SHOWS
WIDELY SCATTERED/SCATTERED SHOWERS ALONG WITH A FEW ISOLATED
THUNDERSTORMS ALONG THE COASTAL PLAIN AND EASTERN MIDLANDS. BOTH
NAM/GFS SHOW INCREASING MOISTURE ACROSS THE AREA AS FLOW INCREASES
FROM THE EAST AND SOUTHEAST. PW VALUES THIS MORNING RANGING FROM
1.5 INCHES WESTERN CWA TO NEAR 2.0 INCHES ALONG THE COAST WILL
INCREASE THROUGH THE DAY. MODELS INDICATE VALUES ABOVE 2.0 INCHES
BY THIS AFTERNOON AND TONIGHT ACROSS THE CWA. BECAUSE OF ALREADY
SATURATED SOILS AND HIGH LEVELS ON MANY LAKES...RIVERS AND
STREAMS...WILL ISSUE A FLASH FLOOD WATCH FOR THE MIDLANDS AND
CENTRAL SAVANNAH RIVE AREA BEGINNING AT 8 AM THIS MORNING THROUGH
8 AM SUNDAY MORNING. EXPECT SHOWER/THUNDERSTORM ACTIVITY TO
INCREASE THROUGH THE DAY AS THE AIRMASS BECOMES MORE MOIST ALONG
WITH INCREASING MOISTURE CONVERGENCE AND INSTABILITY. THESE SHOWERS
AND THUNDERSTORMS WILL HAVE THE CAPABILITY OF PRODUCING LOCALLY
HEAVY RAINFALL IN A SHORT PERIOD OF TIME AS STORMS WILL ONLY BE
MOVING AROUND 10 MPH. RAINFALL RATES OF 1 TO 2 INCHES PER HOUR
ARE POSSIBLE. GUIDANCE AND LOCAL NUMBERS ARE REASONABLY CLOSE
THROUGH THE PERIOD WITH BOTH POPS AND TEMPERATURES. HAVE STAYED
NEAR CONSENSUS FOR TEMPERATURES AND POPS.
&&
.SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/...
BY SUNDAY AND MONDAY...THE AXIS OF DEEPEST MOISTURE WILL HAVE
SHIFTED WESTWARD FROM THE SAVANNAH RIVER INTO AL/GA.
HOWEVER...MODELS DO SHOW A GOOD DEEP ONSHORE FLOW AND EXPECT
ADDITIONAL SHOWERS/THUNDERSTORMS ON SUNDAY AND MONDAY...BUT COVERAGE
SHOULD NOT BE A GREAT AND POPS WILL GRADUALLY DIMINISH THROUGH THE
PERIOD. HAVE STAYED WITH A CONSENSUS OF POPS THROUGH THE
PERIOD...BUT BELOW CONSENSUS FOR TEMPERATURES...MAINLY AFTERNOON
MAX TEMPS. ALTHOUGH RIDGE WILL BE STRENGTHENING NORTH OF THE CWA
AND MOISTURE AXIS HAS SHIFTED WESTWARD...MOIST ATMOSPHERE AND
SOILS WILL SLOW THE RISE IN TEMPERATURES.
&&
.LONG TERM /TUESDAY THROUGH FRIDAY/...
THINGS SHOULD START TO DRY OUT NEXT WEEK. MODELS CONTINUE TO
SUPPORT THE UPPER TROF RETROGRADING TO THE SOUTHWEST INTO TEXAS
WITH AN UPPER LEVEL RIDGE BUILDING INTO OUR AREA FROM THE NORTH
THROUGH MIDWEEK. THE RIDGE APPEARS TO BEGIN BREAKING DOWN AS THE
WEEK ENDS INTO NEXT WEEKEND. WITH LITTLE DYNAMICS IN
PLACE...EXPECT A MORE TRADITIONAL SUMMERTIME PATTERN WITH
SEASONABLY WARM DAYS AND THE POSSIBILITY OF AFTERNOON/EVENING
CONVECTION. TEMPERATURES ARE EXPECTED TO BE CLOSER TO NORMAL
WITH HIGHS MOSTLY IN THE LOWER 90S AND LOWS IN THE LOWER 70S.
&&
.AVIATION /08Z SATURDAY THROUGH WEDNESDAY/...
FRONTAL BOUNDARY STALLED OVER THE MIDLANDS WITH A MOIST AND UNSTABLE
AIRMASS IN PLACE. SHOWERS ALREADY IN THE REGION SO WILL KEEP TEMPO
ACROSS CAE/CUB/OGB. HIGH CONFIDENCE FOR MVFR CIGS THROUGH THE
MORNING. ALSO EXPECT A PERIOD OF IFR CEILINGS AROUND SUNRISE.
BY 15Z...SHOULD SEE THE RETURN OF MVFR CONDITIONS ALL TAF SITES.
WIDESPREAD CONVECTION TO DEVELOP FOR THE AFTERNOON WITH MOIST
ONSHORE FLOW AND FRONTAL BOUNDARY IN THE AREA.
EXTENDED AVIATION OUTLOOK...RESTRICTIONS POSSIBLE SUNDAY THROUGH
WEDNESDAY IN LATE NIGHT/EARLY MORNING FOG OR STRATUS AS WELL AS
SCATTERED MAINLY AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS.
