AREA OF HEAVY RAIN PRODUCING THUNDERSTORMS CONTINUE TO DRIFT SLOWLY
SOUTHWARD. DOPPLER ESTIMATED UP TO 10.3 INCHES OF RAIN OVER NORTHERN
SAN SABA COUNTY...BUT HAIL CONTAMINATION SHOULD ACCOUNT FOR SOME OF
IT. NEVERTHELESS 5 INCHES WAS REPORTED IN RICHLAND SPRINGS WHERE
DOPPLER ESTIMATES APPEAR FAIRLY ACCURATE. A FEW AREAS HAVE BEEN
UNDERESTIMATED AS WELL.

BASED ON 12Z DATA...PRECIPITABLE WATERS ACROSS THE AREA ARE REACHING
150 PERCENT OF NORMAL ACROSS THE COUNTY WARNING AREA WITH HIGHEST
PERCENTAGES TOWARD MAF. A THERMAL GRADIENT SETTING UP OVER THE
NORTHERN EDWARDS PLATEAU AND NORTHWEST HILL COUNTRY COULD MEAN THIS
ACTIVITY WILL CONTINUE WELL INTO THE AFTERNOON HOURS. THIS ACTIVITY
WILL ENHANCED BY THE DIFFLUENT FLOW ALOFT AND A SLOWLY NORTHWARD
MOVING SHORTWAVE. THUS AM CONSIDERING FFA FOR SOUTHERN PORTIONS OF
THE COUNTY WARNING AREA BUT WILL COORDINATE FIRST.
