NESDIS IS CONTINUING TO ACCEPT APPEALS ON THE RETIREMENT OF THE SPENES
PRODUCT.  APPEALS CAN BE SUBMITTED BY EMAILING JOHN.SIMKO@NOAA.GOV
.
EVENT...POSSIBLE UPCOMING HEAVY RAIN EVENT ACROSS PORTIONS OF SW TX.
.
SATELLITE ANALYSIS AND TRENDS...CONVECTION OVER FAR SW TX AND TO THE
SE OVER THE BORDER IN MEXICO HAS BLOSSOMED QUICKLY DURING THE PAST
COUPLE OF HOURS WITH VERY MOIST ENVIRONMENT (1.75"-2.0" PW VALUES JUST
E OF ACTIVITY) AND CONFLUENT SW-SE SFC-850MB INFLOW SUPPORTING THE
ACTIVITY. RECENT TRENDS ARE SHOWING A BIT OF ERRATIC CELL MOVEMENTS
WITHIN BATCH OF CONVECTION OVER SW TX THOUGH OVERALL THERE HAS BEEN
AN EASTWARD PROPAGATION LIKELY FROM WEAK COLD POOL FORMATION AND LIGHT
W-WSW MEAN FLOW ALOFT. WITH THE CELLS OVER MEXICO, HAVE SEEN MORE OUTFLOW
GENERATION WITH DEVELOPMENT SPREADING NORTHWARD.
.
OUTLOOK...FOR THE NEXT SEVERAL HOURS, WILL BE WATCHING FOR LIKELY
INTERACTION BETWEEN SW TX CONVECTION SLOWLY PROPAGATING EASTWARD
AND CELLS ALONG NORTHWARD MOVING OUTFLOW COMING OUT OF MEXICO. SOME
CONCERN EXISTS WITH THE HIGH RAIN RATES WHICH WILL OCCUR WITH THIS
UPCOMING MERGER OCCURRING CLOSER TO THE ANALYZED DEEPEST MOISTURE IN THE
REGION. RAP SOUNDINGS ARE SHOWING VERY LITTLE FLOW THROUGH THE COLUMN SO
CONVECTION WILL GENERALLY BE RATHER SLOW MOVING UNTIL COLD POOL FORMATION
OCCURS. HAVE SOME UNCERTAINTY AS TO HOW LONG THE THREAT WILL LAST THOUGH
WITH VISIBLE SATELLITE ANIMATION SHOWING TOWERING CU/NEW CELLS SPREADING
INTO THE SW AND S PORTION OF THE SW TX CONVECTION AND WITH THE PRESENCE
OF CONFLUENT LOW LEVEL INFLOW, DO HAVE A BIT OF CONCERN FOR A GREATER
DURATION HEAVY RAIN THREAT STRETCHING FROM FAR SW TX (PRESIDIO/BREWSTER
COUNTIES) EXTENDING NORTHEASTWARD TO THE AREA ALONG AND AHEAD OF WHERE
THE UPCOMING MERGER IS LIKELY IN THE VICINITY OF METAR STATION K6R6.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10 MINUTES.
