SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 09/22/14 1846Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-EAST:1815Z  JS
.
LOCATION...E SOUTH CAROLINA/SE GEORGIA...
.
ATTN WFOS...ILM...CHS...CAE...FFC...
ATTN RFCS...SERFC...
.
EVENT...POTENTIAL FOR LOCALLY HEAVY RAINFALL WITH WAVE DEVELOPING ALONG
SFC BOUNDARY.
.
SATELLITE ANALYSIS AND TRENDS...OVER THE PAST SEVERAL HOURS WATER VAPOR
IMAGERY SHOWS VERY SIGNIFICANT DEEPENING OF TROF AXIS BACK OVER THE
S CENT/SE US WITH DARKENING SEEN SINKING STEADILY TO THE S TOWARD THE
GULF COAST. THIS IS ALSO EVIDENT IN THE GOES RGB AIR MASS PRODUCT WHICH
REVEALS A COLORIZED PATCH MOVING TO THE SE ACROSS SE TN/N AL/FAR NW GA
THAT`S INDICATIVE OF THE STRENGTH OF THE MID/UPPER LEVEL IMPULSE AND A
SIGN OF SINKING AIR ALOFT. IN ADVANCE OF THIS FEATURE, SEE EVIDENCE IN
BOTH SATELLITE IMAGERY AND OBSERVATIONAL ANALYSIS OF WAVE FORMING ALONG
SFC BOUNDARY LIKELY MOVING NE  FROM E CENT GA NOW INTO W CENT SC. A
LOOK AT THE MOISTURE PROFILES SHOW DECENT BUT NOT OVERLY EXCESSIVE
MOISTURE. THE RECENT BLENDED TPW PRODUCT DOES PICK UP ON AN INCREASE
MAINLY OVER E SC WITH PW VALUES RISING TO SLIGHTLY OVER 1.5". WITH THE
FORMATION OF THE WAVE AND DAYTIME HEATING OCCURRING, STARTING TO SEE AN
INCREASE IN INSTABILITY ALONG AND AHEAD OF THE SFC BOUNDARY IN THE GOES
SOUNDER PRODUCTS FROM S CENT GA TO SE GA AND S SC WITH TRENDS POINTING
TOWARD THE INSTABILITY INCREASING OVER THE NEXT COUPLE OF HOURS FARTHER
TO THE NE ACROSS THE REMAINDER OF E SC. ANALYSIS ALSO SHOWS A BULLS EYE
OF SFC BASED MOISTURE CONVERGENCE CENTERED OVER E SC.
.
SHORT TERM OUTLOOK VALID 1900-0100Z...MEDIUM TO HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...EXPECT CONVECTION TO CONTINUE TO DEVELOP ALONG AND
AHEAD OF SFC BOUNDARY OVER S CENT TO SE GA AND ROUGHLY OVER THE EASTERN
THIRD OF SC OVER THE NEXT COUPLE OF HOURS POSSIBLY ENHANCED BY SEA BREEZE
OVER SC AS EVIDENCED BY RECENT CU LINE MOVING INLAND FROM COASTAL SC IN
VISIBLE ANIMATION. AS THE WAVE FORMS, THE INITIAL SW MEAN FLOW BEGINS
TO BACK WHICH MAY HELP TO EVENTUALLY TRANSPORT BETTER MOISTURE FROM THE
ATLANTIC AND ASSIST IN PROLONGING THE RAIN EVENT OVER SE GA/E SC LATER
THIS AFTERNOON AND INTO THE EVENING/OVERNIGHT HOURS WHICH COULD LEAD TO
LOCALLY HEAVIER RAIN TOTALS FOR SE GA/E SC. THE APPROXIMATE THREAT AREA
STRETCHES FROM SE GA NEAR SAVANNAH TO AROUND MYRTLE BEACH SC STRETCHING
INLAND MAYBE 50 MILES OR SO. GRAPHIC OUTLINING THE APPROXIMATE THREAT
AREA SHOULD BE AVAILABLE ON THE INTERNET IN 10 MINUTES.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10 MINUTES.
