SATELLITE ANALYSIS AND TRENDS...VERY OMINOUS LOOKING SITUATION SETTING
UP ACROSS THE REGION EXTENDING FROM NW TX TO S CENT TX. OUTFLOW
FROM COLD POOL CENTERED OVER N CENT TX (INVOF DALLAS-FT WORTH)
HAS APPARENTLY SLOWED ITS SOUTHWARD PROGRESS RESULTING IN AUTOMATED
SATELLITE ESTIMATES IN THE 2.5"-4.0" RANGE WITH POSSIBLY EVEN HIGHER
AMOUNTS FOR THE PAST 2-3 HOURS FOR THE APPROXIMATE REGION INCLUDING
PORTIONS OF LAMPASSAS/BURNETT/BELL/WILLIAMSON/MILAM COUNTIES. A
SECONDARY MAX OF 2.0"-3.0" HAS BEEN ESTIMATED FOR THE AREA CENTERED
AROUND COMMANCHE/HAMILTON/MILLS COUNTIES. HAVE ALSO NOTICED TRENDS IN
IR IMAGERY FOR COLDEST TOPS WITHIN THIS REGION TO EXPAND TO THE SW
AND ALSO NOW TO THE WEST WHICH IS AN INDICATION OF THE INFLUENCE OF
THE APPROACHING NW TX COMPLEX. THIS IS A BAD SIGN THAT THE SCENARIO
OF THE 2 COMPLEXES INTERACTING IS STARTING TO OCCUR WHICH WILL LIKELY
REINVIGORATE THE WESTERN PERIPHERY OF THE CENT TX MCS RESULTING IN THE
POTENTIAL FOR SOME EXTREMELY HEAVY RAINS OVERNIGHT AS CELLS TRAIN AND
MERGERS OCCUR. WITH A BOUNDARY NOW IN PLACE AT OR CLOSE TO THE SFC TO
FOCUS THE ACTIVITY ALONG WITH TREMENDOUS DIFFLUENCE ALOFT AS SEEN IN
WATER VAPOR LOOPS GREATLY AIDED BY SUBTROPICAL ANTICYCLONIC FLOW AROUND
NORTH SIDE OF MEXICO UPPER LEVEL RIDGE BELIEVE THE THREAT FOR EXCESSIVE
RAINFALL WILL LAST THROUGH THE NIGHT AND INTO THE MORNING. AN ANNOTATED
SATELLITE GRAPHIC DEPICTING THE THREAT AREA WILL BE POSTED ON THE INTERNET
ADDRESS LISTED BELOW IN APPROXIMATELY 10 MINUTES.
