SATELLITE ANALYSIS BRANCH/NESDIS---NPPU---TEL.301-763-8678
LATEST DATA USED: GOES-12 1532Z   HANNA
.
LOCATION...TEXAS...
.
ATTN WFOS...FWD...SJT...
ATTN RFCS...WGRFC...
.
EVENT...HEAVY RAIN REDEVELOPING JUST NW OF DAL....REGENERATION ALSO
OCCURRING NEAR THE FORT WORTH METRO AREA
.
SATELLITE ANALYSIS AND TRENDS...EARLIER CONVECTIVE CELLS THAT MOVED
THROUGH THE DALLAS AREA HAVE WEAKENED AS THEY MOVED SE OF THE CITY.
SINCE THEN CLOUD TOPS HAVE RAPIDLY COOLED FROM NE TARRANT COUNTY INTO NW
DALLAS COUNTY BOUNDED APPROXIMATELY BY DFW, ADS AND DAL.  RECENT REPORTS
OUT OF DFW CONFIRM MANUAL SATELLITE ESTIMATED RAINFALL RATES OF 2-3"/HR.
.
FURTHER TO THE WEST MESOSCALE BOUNDARIES FROM EASTLAND COUNTY AND
COMANCHE COUNTIES APPEAR TO BE INTERSECTING NEAR RAPIDLY COOLING AND
EXPANDING CONVECTION OVER SE PARKER COUNTY AND WESTERN TARRANT COUNTY.
WOULD ALSO EXPECT RAINFALL RATES OF 2-3"/HR IN THESE AREAS.
.
AUTOMATED SATELLITE ESTIMATES ENDING AT 15Z GENERALLY RANGE FROM 2-4"
FROM E JACK COUNTY TO N DALLAS COUNTY OVER THE LAST 6HRS.  CONSIDERING
THE NOTED LOW BIAS OF AUTOMATED SATELLITE ESTIMATES IN WARMER CLOUD TOP
AND EXTREMELY MOIST ATMOSPHERIC CONDITIONS, BELIEVE LOCALIZED TOTALS IN
EXCESS OF 5" ARE NOT OUT OF THE QUESTION.
.
WEAK UL IMPULSE THAT LIKELY CONTRIBUTED TOWARDS INCIPIENT CONVECTION
APPEARS AS THOUGH IT HAS LIFTED NE OF THE AREA.  STILL THOUGH, LOCAL
AREA VWPS CONTINUE TO SHOW MODEST SWRLY LLJ HELPING TO CONTINUE TO
ISENTROPICALLY LIFT AND TRANSPORT MOIST AND UNSTABLE AIR MASS INTO UPWIND
EDGE OF COMPLEX.  ADDITIONALLY IT APPEARS AS THOUGH UPSTREAM IMPULSE
OVER THE TRANS PECOS REGION MAY TRY TO LIFT NE THROUGH THE AFTERNOON
PROVIDING ADDITIONAL SYNOPTIC FORCING/DESTABILIZATION TO CONTINUE THE
THREAT FOR AREAS OF LOCALIZED HEAVY RAINFALL.
