The episode as NWS TSA wrote it up.
A moist and very unstable air mass was in place over eastern Oklahoma ahead of a dry line that approached the area during the afternoon. A warm layer of air aloft suppressed thunderstorm development until late in the evening. Thunderstorms that formed along and just ahead of the dry line over northeastern Oklahoma became severe with large hail and damaging straight-line wind. A second round of storms formed on a cold front that moved through the region during the overnight hours and a few of those storms also became severe with damaging wind gusts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tulsa, OK wrote its last area forecast discussion before the first event at Jun 7, 7:56 PM CST, 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 856 PM CDT THU JUN 7 2007 .MESOSCALE UPDATE... AS THE COLD FRONT APPROACHES FROM THE NORTHWEST THE ORIENTATION OF THE DRYLINE IS BECOMING MORE NORTHEAST-SOUTHWEST ACROSS NORTHERN OKLAHOMA. THIS WILL ALLOW DEVELOPING CELLS MORE RESIDENCE TIME IN / NEAR THE BOUNDARY ZONE. THIS SHOULD AID STORM DEVELOPMENT IN OSAGE AND PAWNEE COUNTIES IN THE NEXT COUPLE OF HOURS. CAPE BELOW 700MB IS RATHER LOW IN THESE AREAS...BUT THE TOTAL CAPE REMAINS BETWEEN 2500 AND 3600 J/KG WITH DEEP LAYER SHEAR NEAR 50 KNOTS.
