SATELLITE ANALYSIS AND TRENDS...LATEST WV IMAGERY INDICATES BROAD
TROF MOVING TO THE E OVER FAR WRN MEXICO/SRN CA AND ASSCD ANOMALOUS
UL CIRCULATION EVIDENT NEAR UT/AZ BORDER. S/WV IMPULSE WITHIN THE TROF
AXIS IS CURRENTLY EJECTING OUT TOWARDS SWRN NM...INCREASING LARGE SCALE
FORCING FOR ASCENT DOWNWIND IN ERN NM/NRN TX. CONVECTION HAS ALREADY
DEVELOPED IN RESPONSE TO THIS FORCING IN ERN NM OUT AHEAD OF FRNTL
BNDRY THAT EXTENDS FROM NEAR ABQ TO THE SE TOWARDS SRR...THEN TO THE
E TOWARDS HOB AND BEYOND. 50 KT SERLY LLJ BEYOND THE FRONT IS SEEN IN
REGIONAL VWPS NOSING UP TO KMAF...AND IS FAVORABLY ORIENTED TO ALLOW
FOR INCREASED MOISTURE/INSTABILITY FLUX. SBCAPE VALUES BEHIND FRONT
MAX OUT NEAR 2500-3000 J/KG ACROSS CENT TX PER SPC MESOANALYSIS...AND
GPS PWS INDICATE INCREASING MOISTURE TREND OVER PAST FEW HRS WITH PWS
INCREASING TO 1.2"-1.4" IN CENT/W CENT TX...WHICH IS AOA 2 STD DEV FOR
THE AREA IN MAY.
.
ANTICIPATE CONVECTION TO GROW UPSCALE OVER NEXT FEW HRS AND LATER INTO
THE MORNING AS S/WV IMPULSE APPROACHES THE REGION...POSSIBLY AIDED BY UL
JET DYNAMICS FROM UL JET STREAK SEEN IN GOES SATL DERIVED WINDS AS IT
SLOWLY MOVES TO THE ENE. CONVECTION REMAINS FOCUSED BACK ACROSS ERN NM
WHERE MOISTURE CONVERGENCE IS STRONGEST AND FORCING FOR ASCENT FROM MID
LVL S/WV ALSO REMAINS MOST FOCUSED. ONE LIMITING FACTOR APPEARS TO BE
HIGHER CIN VALUES FROM SPC MESOANALYSIS ACROSS NRN TX...WHICH IS LIKELY
INHIBITING GREATER CONVECTIVE DEVELOPMENT AT THE MOMENT. DID NOTICE A
DECREASE IN CIN HOWEVER ACROSS ERN NM INTO NERN TX NEAR BAILEY/COCHRAN
COUNTIES DUE E. ANOTHER BIG LIMITING FACTOR MAY ALSO BE CONVECTIVE
DEVELOPMENT OCCURRING FARTHER S NEAR THE BIG BEND INVOF DRT. AS THIS
OCCURS IT MAY INHIBIT INFLOW TOWARDS NRN TX. EVEN STILL...LATEST IR
IMAGERY INDICATES COOLING CLOUD TOPS AND CONVECTIVE DEVELOPMENT OCCURRING
INVOF YOAKUM/GAINES COUNTIES. WITH 50 KT SERLY LLJ FAVORABLY ORIENTED
TO GREATER MOISTURE/INSTABILITY AND REGIONAL VWPS INDICATING GNRLY
UNIDIRECTIONAL FLOW AT MID-UPPER LVLS...CELL TRAINING APPEARS TO BE THE
MAIN THREAT FOR HVY RAINS. THIS IS EVIDENCED IN ERN NM AS CONVECTION IS
TRAINING FROM SSW TO NNE...JUST MAKING ITS WAY ACROSS THE NM/TX BORDER.
