EVENT...NE TEXAS CONVECTIVE COMPLEX FOLLOWING OUTFLOW INTO N
LOUISIANA...WRAP AROUND MOISTURE FOR MODERATE SHOWERS N CENTRAL TEXAS...
.
SATELLITE ANALYSIS AND TRENDS...MCV MOVING ACROSS N CENTRAL TEXAS LOSING
SOME OF ITS PRESENTATION ON SATELLITE...BUT MOISTURE ENTRAINED APPEARED
TO HAVE MORE OF AN EFFECT IN HELPING BAND OF SHOWERS THAT DEVELOPED
ACROSS S CENTRAL OK AND HAVE RECENTLY EXPANDED INTO N CENTRAL TX TO
THE NW OF DALLAS.  WILL TALK MORE ABOUT THAT LATER IN THE DISCUSSION.
TO THE EAST...NORTH-SOUTH  CONVECTIVE BAND MOVING OUT PRETTY QUICK AND
GENERALLY FOLLOWING ALONG OUTFLOW FROM EARLIER THIS MORNING`S ARKANSAS
MCV. INTERACTION/INTERSECTION OF OUTFLOW WITH CONVECTIVE TAIL MARKS THE
MOST ENHANCED RAINFALL AND WITH PWAT VALUES STILL CLOSE TO 1.6"...ISOLATED
SPOT COULD CONTINUE TO GET CLOSE TO THOSE AMOUNTS..MAYBE SLIGHTLY HIGHER
IN AN HR OR SO FROM UPSHUR TO HARRISON COUNTY TX AND INTO NW LA ACROSS
BOSSIER AND CADDO PARISH AND THEN EAST FROM THERE.
INTERESTING THAT MCV COMMA COMPLEX TAKING ON A SLIGHT NEGATIVE TILT AND
ALMOST LOOKS LIKE IT WAS ACTING LIKE A MINI CONVEYOR BELT SENDING DEEP
REINFORCING MOISTURE BACK INTO N CENTRAL TX FOR EXPANDING CONVECTION
GENERALLY NOW CENTERED MONTAGUE TO YOUNG COUNTY AND TO THE NW OF DALLAS.
SOMETHING TO KEEP A EYE ON AS PWATS OVER THAT AREA WERE MAXING OUT CLOSE
TO 1.6"-1.7".
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1500-1800Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...WILL PUSH HEAVIEST ACTIVITY OUT OF NE TX
AND ACROSS NW LOUISIANA AND EXT SW ARKANSAS AND EAST FROM THERE ALONG
REMAINS OF OUTFLOW BOUNDARY.  MORE POSSIBLE CONCERN AND UNCERTAINTY WITH
ENTRAINED MOISTURE WITH CONVECTIVE BAND N CENTRAL TEXAS THAT COULD TRY
TO EXPAND A BIT MORE AND GET CLOSE TO THE DALLAS AREA, DESPITE STABILITY
LEFT IN THE WAKE OF HVY RAIN ROM MCV EARLIER THIS MORNING.  GOES WATER
VAPOR SHOWED ANOTHER WEAK SHORT AVE PUSHING ACROSS SE COLORADO TOWARD
THE TX/OK PANHANDLES...SO NOT SURE WHETHER THAT WILL HELP KEEP CURRENT
MONTAGUE TO YOUNG COUNTY ACTIVITY GOING AND ALLOW IT TO SHIFT SOUTHEAST
DURING THIS PERIOD.  BUT SINCE SOILS VERY MOIST...CERTAINLY SOMETHING
TO KEEP AN EYE ON FOR THE AFTERNOON.
