SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 08/01/14 0500Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-E 0445Z GG
.
LOCATION...N LOUISIANA...SE TEXAS...
.
ATTN WFOS...JAN...LCH...SHV...HGX...
ATTN RFCS...LMRFC...WGRFC...
.
EVENT...WANING SE TX CONVECTION FOCUS SHIFTING TO CONFLUENT DEEP MST
CONVERGENCE NEAR 85H LOW ACROSS N LA.
.
SATELLITE ANALYSIS AND TRENDS...SINGLE VERY LARGE VERY COLD CONVECTIVE
CLUSTER OVER HOUSTON CONTINUES TO CYCLE WITH OVERSHOOTING TOPS AND
GIVEN EXTREMELY DEEP MST PROFILE CONTINUES TO BE HIGHLY EFFICIENT WITH
2-3"/HR RATES AND SLOW SOUTHERN PROGRESSION.  HOWEVER...REST OF THE
OVERALL LINE HAS BEGUN TO RAPIDLY WARM AND THREAT LOOKS TO BE SHIFTING
NORTHWARD AS NEW CONVECTIVE TOWERS ALREADY BEGINNING TO BLOSSOM ALONG
LOW LEVEL CONVERGENCE BNDY  UNDER THE INFLUENCE OF DEEPING 85H LOW UNDER
INFLUENCE OF APPROACHING 60-70KT LEFT EXIT REGION ACROSS NE TX/SW AR
AND NW LA ATTM.   SWIR (4um) SHOWS A WELL DEFINED LOW LEVEL CIRCULATION
ACROSS N TX WITH DEFINING BNDY FEATURES JUST SOUTH OF THE RED RIVER AND
ENELY CLD FEATURES ALONG THE NORTHERN PORTIONS OF THE CIRC IN E OK/CENT
AR AIDING SQUEEZE/CONVERGENCE IN THIS ZONE.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 0500-1200Z...MEDIUM-HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WITH THE AFOREMENTIONED SETUP... INCREASING 85H
FLOW HAS BEEN SEEN IN THE VAD PROFILE AND ANALYSIS FIELDS WITH SOLID
CONFLUENCE OF SWLY FLOW THAT SHOULD CONTINUE TO ENHANCE WITH WEAKENING
OF THUNDERSTORMS IN SE TX AND SELY FLOW ACROSS S AND CENTRAL LA ATTM.
LOW LEVEL PROFILES SHOW A SATURATED ENVIRONMENT WITH TPWS IN EXCESS
OF 2.25" AND 85H TDS OVER 16C.   BEST MST CONVERGENCE ANALYSIS IS
ACCENTUATED FROM RUSK COUNTY TX ACROSS TO WINN PARISH... AND SIMLIARLY
TO SE TX CONVECTION EARLIER TONIGHT WILL BE HIGHLY EFFICIENT WITH 2-3"/HR
RATES... WITH SLOW PROGRESSION TOWARD THE EAST AND SE... 5-6" TOTALS ARE
NOT OUT OF POSSIBILITY WITH UPSTREAM DEVELOPMENT ACROSS NE TX/SW AR NEAR
THE 85H LOW AND BEST UVV ASCENT FROM JET DYNAMICS...REPEATING OVER THE
SAME AREAS IN N LA FOR MUCH OF THE OVERNIGHT EARLY MORNING.
