Hail and Damaging Winds in Oklahoma, July 13, 2003

EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
312 AM CDT SUN JUL 13 2003

JUST BEFORE 3 AM...THUNDERSTORMS STARTED DEVELOPING EASTWARD IN THE
WATCH AREA. WILL WAIT TILL THE LAST MINUTE BEFORE SENDING ZONES AND
ADJUSTING TO HOW THINGS LOOK. WITH WEAK BOUNDARY AND UPPER AIR SHORT
WAVE MOVING ACROSS THE AREA IN THE NORTHWEST FLOW...NOT HARD TO
JUSTIFY A WATCH FOR MUCH OF OK. ONLY QUESTION SEEMS TO BE IS HOW
WIDESPREAD ARE THE THUNDERSTORMS GOING TO BE. WILL KEEP 30 TO 40
POPS ACROSS THE AREA TODAY WITH ONLY 20 PERCENT IN THE SOUTHEASTERN
SECTION TONIGHT. THIS SEEMS THE MOST REALISTIC WITH CURRENT
CONDITIONS.

LOOKS LIKE GUIDANCE HAS A FAIRLY GOOD HANDLE ON THE TEMPS AND WILL
STICK PRETTY CLOSE TO THEM. DRY FORECAST AFTER THIS SYSTEM MOVES
OUT.
