EVENT...DEVELOPING CONVECTION IN BIG BEND
.
SATELLITE ANALYSIS AND TRENDS...RECENT IR LOOP SHOWS RAPID DEVELOPMENT OF
THUNDERSTORM CLUSTERS ALONG THE FRONTAL BOUNDARY IN THE BIG BEND/PECOS
RIVER REGION.  VERY STRONG MOISTURE TRANSPORT ALONG THE RIO GRANDE INTO
AN EASTWARD ACCELERATING FRONTAL BOUNDARY WITH AMPLE SFC MOISTURE OF
60 PLUS TDS AS LEAD TO SIGNIFICANT MOISTURE CONVERGENCE.  WV LOOP SHOWS
STRONG JET STREAK MOVING ACROSS NORTHERN MEXICO AT THIS TIME LEAVING THE
BIG BEND ON THE DIVERGENT AGEOSTROPHIC PORTION OF THE JET FOR ENHANCED
OUTFLOW ALOFT FOR INCREASED VVS.  THIS HAD LEAD TO RAPID DEVELOPMENT
AND COOLING OF THE COMPLEX OVER E PECOS/N TERRELL COUNTIES AND NOW TO
THE BURST OF CONVECTION ALONG S BREWSTER COUNTY WHERE FFG VALUES ARE
WELL BELOW 1"...WHICH IS SHOULD BE EASILY ECCLIPSED BY STORMS OF THIS
MAGNITUDE IN SUCH A MOISTURE RICH ATMOSPHERE FOR THIS PORTION OF TX.
ADDITIONAL INSTABILITY WITH UPPER LEVEL COOLING ALOFT IS JUST STARTING
AS A SPOKE OF VORTICITY IS SEEN ROTATING THROUGH THE BASE OF THE STALLED
UPPER LOW (CURRENTLY SEEN IN WV OVER W PRESIDO COUNTY).  RAIN TOTALS
NEAR 1-2" CAN BE EXPECTED IN WITH THE AFOREMENTIONED CELLS.
