AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
906 PM CDT SUN JUN 15 1997

FTW ZONE UPDATE APPEARS SUFFICIENT AS MOST OF THE CURRENT ACTIVITY IS
MOVING NORTHEAST AT 30-35 MPH INTO THE EASTERN BIG COUNTRY AND
NORTHERN HEARTLAND. EXPECT ONLY BRIEF AND MINOR FLOODING TO BE
POSSIBLE OVER THESE AREAS WITH RAINFALL AMOUNTS EXPECTED TO REMAIN
LESS THAN AN INCH. DONT SEE NEED TO CANCEL FFA FOR OTHER AREAS AS
LOWEST FFG VALUES OVER THE WESTERN BIG COUNTRY WHERE LESS ACTIVITY IS
EXPECTED. ANOTHER WAVE OF ACTIVITY SEEN BY SATELLITE AND KMAF DOPPLER
WILL AFFECT THE AREA DURING THE OVERNIGHT HOURS...BUT MOST ACTIVITY
SEEMS TO BE FOLLOWING THE DEEPER THETA-E MOISTURE TO THE SOUTH. DIME
SIZED HAIL IS THE ONLY SEVERE REPORT SO FAR...BUT VIEW IRION STORM
INDICATED A MICROBURST OVER RURAL AREAS. STORMS ARE ALSO SHOWING WEAK
ROTATION...BUT SPEED SHEAR FROM UPPER JET APPEARS TO BE KNOCKING OFF
THE TOPS OF THE STORMS...SO SUPE RCELL DEVELOPMENT WILL BE HARD TO
COME BY. WITH LATEST UPDATES ALREADY IN FROM SAT AND FTW...CURRENT
FORECASTS ARE ON TRACK.
