THIS AFTERNOON THE MCV WAS CENTERED OVER REAL COUNTY DRIFTING NORTHWARD.
AN ASSOCIATED LINE OF SHOWERS AND THUNDERSTORMS EXTENDED FROM BURNET

TO CELL TRAINING RESULTING IN LOCALIZED FLOODING. THE THREAT FOR
LOCALLY HEAVY RAINFALL AND FLASH FLOODING ASSOCIATED WITH THE LINE
OF CONVECTION WILL CONTINUE THRU THE REST OF THE AFTERNOON AS HEATING
INTERACTS WITH PWS OF 1.5 TO 1.75 INCHES. STRONG OUTFLOW WINDS OF
30 TO 40 MPH WERE ALSO OCCURRING IN ADVANCE OF THE LINE. THE SLOW
MOVING LINE WILL CONTINUE TO MOVE EASTWARD FOR THE REMAINDER OF
THIS AFTERNOON. THE AREAL COVERAGE OF CONVECTION WILL DIMINISH
OVERNIGHT WITH THE LOSS OF DAYTIME HEATING. ANOTHER ROUND OF
SHOWERS AND THUNDERSTORMS IS POSSIBLE ON SATURDAY AS ANOTHER UPPER
LEVEL IMPULSE MOVES ACROSS SOUTH CENTRAL TEXAS. HIGHS ON SATURDAY
WILL BE CLOSE TO SEASONAL NORMALS.
