SATELLITE PRECIPITATION ESTIMATES..DATE/TIME 12/19/14 0652Z
SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-683-1404
LATEST DATA USED: GOES-13 0630Z KUSSELSON
NOAA AMSU: 0320Z 0410Z  DMSP SSMIS:2330Z NASA TRMM: 0310Z

LOCATION...LOUISIANA...TEXAS...

.
EVENT...JET, HIGHEST MOISTURE, FRONTAL BOUNDARY FIGHTING IT OUT FOR
NM/W TX SHORT WAVE ATTENTION TO HELP PRODUCE HIGHEST RAIN AMOUNTS NEXT
FEW HRS...
.
SATELLITE ANALYSIS AND TRENDS...SATELLITE ANALYSIS OF FEATURES FIGHTING
IT OUT TO SEE WHICH PROVIDES THE RIGHT MIX FOR A COMPROMISED AREA AND
AMOUNT OF MODERATE TO HVY RAINFALL SOMEWHERE SE TEXAS INTO LOUISIANA.
JET AS PER LATEST GOES WATER VAPOR LOOP AND SATELLITE UPPER LEVEL WINDS
WAS CENTERED APPROXIMATELY MAVERICK TO NEWTON COUNTY TEXAS INTO CENTRAL
LOUISIANA/SW MS.  HIGHEST PRECIP WATER VALUES COVERED SOUTHERN TO CENTRAL
TEXAS AND EAST THRU SE TEXAS...S AND C LA WITH VERY HIGHEST NEAR 1.6"
INTERIOR SOUTHERN TO SE TEXAS TO NEAR THE SW LA-TX BORDER AREA.  LATEST
MICROWAVE CHANNEL IMAGERY ALONG WITH SURFACE OBS AND ASCAT SATELLITE
SCATTEROMETER WINDS SHOWED FRONTAL BOUNDARY NEAR THE TX COAST AND REFUGIO
COUNTY INLAND TO NEAR LASALLE-MCMULLEN COUNTY.  TO THE WEST..BEST LOOKING
SHORT WAVE WAS COMING OUT OF EASTERN NM...POSSIBLY AS TWO FRACTURED SHORT
WAVES AND A FEW WEAKER IMPULSES OUT AHEAD ACROSS CENTRAL TO NW TEXAS THAT
WERE BEGINNING TO STRETCH THEIR FORCING INTO CENTRAL AND INTERIOR EASTERN
TEXAS.  SO QUITE A FEW IMPORTANT FEATURES FOR RAINFALL PRODUCTION AND A
FEW VERY IMPORTANT ITEMS NOT QUITE LINED UP FOR EXCESSIVE...BUT CERTAINLY
ABLE TO SQUEEZE OUT MODERATE TO LOCALLY HVY NEXT FEW HRS IN A NARROW AREA
CLOSE TO CURRENT WPC 6HR QPF THAT COVERS THE 06-12Z PERIOD.    LATEST NASA
TRMM 0310Z PASS SHOWED A MAX 10 MILE AREAL AVERAGE INSTANTANEOUS RAIN
RATE OF 0.55"/HR CENTERED BEXAR COUNTY AND A 0.73"/HR CENTERED GONZALES
AND 0.59"/HR CENTERED NEAR THE GONZALES-BASTROP COUNTY BORDER AREA AND
THIS WENT ALONG WITH THE LOWER RESOLUTION 0400Z NOAA AMSU RAIN RATES.
AND THIS AREA OF HIGHEST RAIN RATES WAS RIGHT IN THE MIDDLE OF JET TO THE
NW OF MAX PWATS BUT IN WEAK TO MODERATE TO LOW LEVEL MOISTURE ADVECTION
THAT ALSO INCLUDED A WEAK PACIFIC MOISTURE CONNECTION ON 700MB TRANSPORT.
.
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 0645-0945Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WILL FOCUS ON THE MID TO UPPER TEXAS COAST AND
INLAND AND TO THE NORTHWEST AND JUST EAST AND NE OF THE SAN ANTONIO AREA
AND POSSIBLY EXTENDING INTO SW LOUISIANA.   LIKE MENTIONED IN CURRENT
WPC EXCESSIVE DISCUSSION, " FFG VALUES ACRS
THIS AREA ARE RELATIVELY HIGH AND THUS ANY RUNOFF CONCERNS SHOULD BE
RATHER ISOLD.
