What happened

The episode as NWS OUN wrote it up.

A weak cold front moved southeast into Oklahoma during the late afternoon hours. Ahead of the front, numerous boundaries left over from previous days thunderstorms, became a focus for strong to severe thunderstorm development. Thunderstorms developed during mid afternoon hours, extending from parts of central into northern Oklahoma. The strongest storms eventually organized over northern Oklahoma and moved southeast through the evening hours. The hail reached quarter size at times, with winds reaching 60 mph over some areas. No damage was reported with the thunderstorms. The activity moved south into central Oklahoma by mid evening before weakening.

What forecasters said that day

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
329 PM CDT TUE JUL 28 2009

.DISCUSSION...
GENERAL WEST-NORTHWEST FLOW ALOFT CONTINUES WITH VARIOUS SMALL
SCALE WAVES IN THE FLOW... VERY LITTLE CONVECTIVE INHIBITION...
AND MULTIPLE WEAK SURFACE BOUNDARIES. WE WILL BE SEEING SCATTERED
SHOWERS AND THUNDERSTORMS WITH THESE INGREDIENTS IN PLACE ALTHOUGH
IT BECOMES QUITE A CHALLENGE TO PINPOINT SPECIFIC GEOGRAPHY OF THE
HIGHEST PRECIPITATION CHANCES ESPECIALLY AS WE GOT FARTHER AHEAD IN
TIME WHEN WHAT OCCURS ON THE MESOSCALE OR LOWER WILL INFLUENCE
FUTURE CONVECTIVE EVOLUTION. HAVE HIT THE GEOGRAPHY AND TIME
PERIODS THAT HIGHEST WITH THE PROJECTED TIMING OF THE MORE-
SYNOPTIC SCALE FRONT. DO NOT LIKE SOME OF THE EXTREMA IN THE MAV
POP FIELDS AND GFS QPF WITH THE CONVECTIVE FEEDBACK SIGNALS...
ALTHOUGH THE GENERAL INCREASE IN POPS SEEMS REASONABLE.

ALTHOUGH THERE IS STILL SOME SPECIFIC DISAGREEMENT IN THE MEDIUM
RANGE MODELS EVOLUTION OF THE PATTERN... THERE ARE COMING MORE
INTO AGREEMENT WITH THE GFS IS LESS AGGRESSIVE IN BUILDING THE
UPPER RIDGE OVER THE AREA ALTHOUGH THE BEST FLOW REMAINS NORTH AND
NORTHEAST OF THE AREA. WITH SOMEWHAT BETTER AGREEMENT... DID MAKE
SOME ADJUSTMENT TO THE EXTENDED PERIODS BEGINNING WITH SUNDAY TO
TREND TOWARD THIS SOLUTION.
