EVENT...UPDATE TO PREVIOUS SPE FOR ONGOING HEAVY RAINS
.
SHORT TERM OUTLOOK VALID 1045Z-1345Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...CONVECTION THAT ORIGINALLY DEVELOPED IN ERN NM
HAS SHIFTED TO THE NE AND BECOME MORE ORGANIZED OVER THE PAST FEW HRS
AS IT BEGINS TO MERGE WITH CONVECTION DEVELOPING ACROSS NRN TX THAT IS
MOVING NWRD INTO ITS SRN PERIPHERY. THIS MCS AND CONVECTIVE DEVELOPMENT IS
OUT AHEAD OF A WARM FRNTL BNDRY MOVING TO THE N CURRENTLY ANALYZED JUST
TO THE S OF KLBB EXTENDING TO THE ESE TO KDAL AND BEYOND TO KTYR. LOW
LVL WINDS ACROSS MUCH OF TX HAVE VEERED TO MORE SRLY AND REMAIN BTWN
40-50 KTS PER REGIONAL VWPS...PERSISTENTLY ADVECTING ANOMALOUSLY HIGH
MOISTURE/INSTABILITY TOWARDS THE TX PANHANDLE. THIS IS EVIDENCED BY GPS
PWS INCREASING TO 1.0"-1.2" JUST IN THE LAST FEW HRS ALONE. A MORE SRLY
LLJ MAY ALSO ALLOW FOR INCREASED POTENTIAL OF BACKBUILDING CONVECTION
ALONG THE SRN FLANK OF THE MCS...WHICH HAS BEEN NOTED IN LATEST RADAR
DATA INVOF KCVS. INSTABILITY SHARPLY DROPS OFF TO THE N OF A KCVS TO
KCDS LINE...WHICH MAY TEMPER RAINFALL RATES AND MCS SURVIVABILITY AS IT
MOVES TO THE NE. EVEN STILL...WITH PW VALUES AOA 2 STD DEV IN THE AREA OF
DISCUSSION AND SBCAPE VALUES INCREASING BY 1000 J/KG OVER PAST FEW HRS
JUST AHEAD OF FRNTL BNDRY NEAR BEST MOISTURE CONVERGENCE...IMAGINE THAT
HEAVY RAINFALL THREAT WILL REMAIN FOR AT LEAST A FEW MORE HRS IN AREAS
THAT EXPERIENCE BRIEF CELL TRAINING OR CELL MERGERS. THIS APPEARS TO PLACE
THE FAR NRN TX PANHANDLE UNDER THE GREATEST HVY RAINFALL THREAT AS THE
MCS MOVES FROM SW-NE OVER THE AREA AND CONVECTION POSSIBLY REGENERATES
ON THE SRN EDGE WHERE INSTABILITY/MST CNVRG IS BEST.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
