Area forecast discussion, Jun 15, 9:07 PM CDT, 1 hour 40 minutes before
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. OAKS
