CENTRAL/ERN TX
.
SHORT TERM OUTLOOK VALID 0655Z-0955Z...MEDIUM-HIGH CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...CONVECTIVE STORMS THAT WERE LOCATED JUST TO SOUTH
OF DALLAS/FT WORTH HAS TAKEN ON A COMMA SHAPE AND BEGUN TO PROPAGATE MORE
QUICKLY TO THE E WHILE IT ALSO APPEARS TO BE TRYING TO CONGEAL WITH THE
LINE OF CONVECTION SEEN RACING EWRD ACROSS CENT TX EXTENDING FROM JUST
S OF SEP TO THE SSW JUST TO THE W OF COT. THE ANOMALOUS MID/UL LOW OVER
NM HAS ESSENTIALLY REMAINED STATIONARY OVER THE PAST FEW HRS AND THIS
CONVECTION REMAINS UNDER LARGE SCALE DIFFLUENCE WHICH CONTINUES TO ALLOW
FORCING FOR ASCENT FOR THE CONVECTION. THE THREAT OF WIDESPREAD EXCESSIVE
RAINS DOES APPEAR TO BE DIMINISHING AS THIS CONVECTION TRANSLATES EWRD
AND MOVES INTO A RELATIVE MIN OF PW SEEN IN BLENDED TPW. LATEST GPS
PW DATA IN THIS AREA THAT THE NRN EXTENT OF THE CONVECTION IS MOVING
INTO READS JUST BELOW 1.0". INSTABILITY REMAINS HIGH HOWEVER...WITH SPC
MESOANALYSIS INDICATING A MAX FOR SBCAPE OF 2000 J/KG JUST AHEAD OF THE
CONVECTION IN NERN TX. SRLY LLJ HAS ALSO ALLOWED FOR INCREASED MOISTURE
FLUX INTO ERN TX AND MORE CONVECTIVE DEVELOPMENT INVOF CORYELL/MCLENNAN
COUNTIES IN TX NEAR WHERE THE TWO CONVECTIVE FEATURES ARE COMBINING.
.
IMAGINE THAT ANY CHANCE FOR HEAVIEST RAINFALL WOULD OCCUR IN AREAS
OF BRIEF TRAINING OF CONVECTION AS THE MCS HAS APPEARED TO PROPAGATE
MORE QUICKLY TO THE E ACROSS CENT/NERN TX AND RAINFALL RATES SEEM TO BE
SLIGHTLY DECREASING WITH LOWER MOISTURE VALUES IN THE AREA OF DISCUSSION.
THE BEST CHANCES FOR THIS BRIEF TRAINING SEEMS TO BE CLOSE TO WHERE
THE STORMS THAT WERE  AFFECTING THE DALLAS/FT WORTH METRO AREA COMBINE
WITH THE LINE OF CONVECTION MOVING EWRD...WHICH APPEARS TO BE NEAR
LIMESTONE/FREESTONE COUNTIES AND AREAS TO THE E. HIGHER FFG VALUES
WITHIN THIS REGION THAT THE CONVECTION IS MOVING INTO MAY ALSO HELP
FURTHER MITIGATE AND HEAVY RAINFALL CONCERNS.

AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
