SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 11/22/14 2259Z

EVENT...UPDATE TO PREVIOUS SPE FOR CONTINUING MOD-LOCALLY HVY RAINS
.
SATELLITE ANALYSIS AND TRENDS...UPPER LOW SPINNING OVER SW TX IS BEGINNING
TO PROGRESS EWD ACROSS THE STATE WITH A LARGE AREA OF MOD-LOCALLY HVY
PRECIP CONTINUING TO FALL OTU AHEAD OF IT OVER CENTRAL/ERN TX. BROAD
DIFFLUENCE PATTERN ALOFT IS EVIDENT IN WV IMAGERY/GOES SATL WINDS AHEAD
OF THE VORTMAX WITH MAX DVGNC SEEMINGLY OVER CENTRAL TX FROM KBMQ SEWD
THROUGH KAUS. SATL/RADAR IMAGERY HAS SHOWN CONTINUED DVLPMT OF WEAK
CELLS WITHIN A ZONE OF LOW LVL CNVGNC THAT EXTENDS FROM THE TX COAST NW
ACROSS CENTRAL TX AND COINCIDES WITH MUCH OF THE ABOVE INDICATED STRONGER
DVGNC ALOFT. HOWEVER LACK OF  INSTABILITY FROM CENTRAL TX E AND NEWD IS
LIMITING INTENSITY OF MOST OF THE CNVCTN WITH THE EXCEPTION BEING FURTHER
SE CLOSER TO THE COAST. BLENDED TPW HAS SHOWN NWD PROGRESSION OF 1.5"
PW VALUES OVER THE PAST FEW HRS OUT OF THE WRN GULF AND NW TWDS CENTRAL
TX HELPING TO MOISTEN THE LOWER LVLS.
.
FURTHER W NR THE SFC LOW...ENHANCED VIS/IR SIGNATURES ARE PRESENT WITH
AN AREA OF CONGEALING CNVCTN THAT IS SLOWLY TRANSLATING EWD. WITH STRONG
LL INFLOW NR THE SFC LOW TO MAINTAIN THEM AND WEAK PROPAGATION VECTORS
IN THIS AREA..THIS MAY RESULT IN SOME LOCALIZED TRAINING AS THE CELLS
SLOWLY PROGRESS EWD FROM CONCHO/MCCULLOCH/COLEMAN COUNTIES.
.
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 2300-0400Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GNRLY EXPECT THE BULK OF THE PRECIP TO CONTINUE
PROGRESSING E/NE ACROSS ERN TX WITH SOME WEAK CNVTN STILL POSSIBLE TO
DVLP ON THE BACK EDGE. BEST LI`S/CAPE VALUES ARE ALL LOCATED FURTHER SW
OF THE PRECIP SHIELD..ESPECIALLY ALONG THE RIO GRANDE. AS S/WV ENERGY
SWINGS EWD OVER THE NEXT FEW HRS..ADDTL CNVCTN SHOULD DVLP WITHIN THE
UNSTABLE AIR MASS OVER SW TX WITH STORMS TRACKING BACK OVER SOME OF THE
AREAS THAT HAD LOCALLY HVY RAINS ALREADY TDY..MOST NOTABLY NR KAUS AND
COUNTIES TO THE S/SW. ALSO MAY NEED TO WATCH SERN PART OF THE DISCUSSION
AREA AS WEAK INSTABILITY OFF THE NWRN GULF AND STRENGTHENING LL CNVGC
OVER THE NEXT FEW HRS HELP TO KEEP STORMS MORE INTENSE JUST N AND NW OF
THE GALVESTON BAY AREA. LEFT EXIT REGION DYNAMICS FROM UPPER JET CROSSING
SRN TX MAY ALSO AID UPTICK IN CONVECTIVE TRENDS LEADING TO HEAVIER RAINS
WITH GREATER THAN 1"/HR LOCALIZED RAINRATES.
