SATELLITE ANALYSIS AND TRENDS...LATEST IR AND VIS
IMAGERY INDICATES MULTIPLE CONVECTIVE CELLS DEVELOPING INVOF
ANDREWS..ECTOR..MARTIN.. HOWARD..GLASSCOCK COUNTIES IN W/CENTRAL TX.
THESE CELLS HAVE BEEN RAPIDLY INTENSIFYING OVER THE PAST HOUR WITH
OVERSHOOTING TOPS EVIDENT PER VIS IMAGERY AND MULTIPLE LIGHTNING
STRIKES HAVE BEEN DETECTED.  ANALYSIS OF 850MB THETA-E FIELD SHOWS
CONVECTION IS FIRING OFF ALONG A NOSE OF HIGHER THETA-E LOCATED OVER
W TX.  A STATIONARY SFC FRONTAL BOUNDARY IS CURRENTLY DRAPED W-E ACROSS
W/CENTRAL TX TO CENTRAL TX IN WITH THE CONVECTION LOCATED JUST TO THE
NORTH OF IT.  MID-LVL WINDS ARE SHOWN TO BE DUE EAST PER STLT DERIVED
WINDS SUGGESTING THAT THE MOTION OF THESE CELLS WILL CONTINUE ON A EWD
COURSE IN ADDITION TO FOLLOWING ALONG THE SFC BOUNDARY.  CURRENTLY THREE
INDIVIDUAL CELLS CAN BE IDENTIFIED IN VIS IMAGERY WITH THE LEADING CELL
INVOF HOWARD..GLASSCOCK..MITCHELL..STERLING COUNTIES AND BEGINNING TO
APPROACH NOLAN AND COKE COUNTIES. MANUAL STLT ESTIMATE TECHNIQUE SUGGESTS
RAINFALL RATES MAY REACH UP TO 1.5"/HR AS CLOUD TOPS CONTINUE TO COOL
ALONG WITH POSSIBLE INITIAL RAIN BURSTS BEING PRODUCED.  THE CURRENT
TREND IS FOR MORE CELLS TO DEVELOP UPSTREAM OF CURRENT CELLS AND MOVE
EWD PRODUCING HVY RAIN FOR THE NEXT SEVERAL HOURS.
