What happened
The episode as NWS OUN wrote it up.
A strong upper level storm system moved east through New Mexico and into the Texas panhandle during the day on the 8th. Thunderstorms developed over northern Texas and crossed into southern Oklahoma during the morning and early afternoon hours. This area of thunderstorms weakened as they crossed the Red River, leaving widespread cloud cover over the region. However, later in the afternoon, the skies cleared over western Oklahoma, and this allowed for heating to commence in advance of the dry line that was sharpening up over the Texas panhandle. Thunderstorms moved into western Oklahoma and became severe over Roger Mills county. Initially, marginally severe hail up to quarter size was reported, but the storm eventually spawned two tornadoes, one of them significant. The first tornado occurred southwest of Hammon, with EF2 damage reported on the southeast side of Hammon. The second tornado occurred farther east, but did not produce any damage.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 332 PM CST MON MAR 8 2010 .DISCUSSION... AN UPPER LOW OVER NEW MEXICO IS CONTINUING ITS EASTWARD PROGRESSION AS AN ASSOCIATED SURFACE LOW IS CENTERED IN THE VICINITY OF FAR SOUTHEASTERN COLORADO. A DRYLINE CONNECTED TO THIS SURFACE LOW HAS SURGED EASTWARD IN THE LAST SEVERAL HOURS...WITH STRONG THUNDERSTORMS OCCURRING JUST AHEAD OF THE DRYLINE. OTHER THUNDERSTORMS HAVE DEVELOPED IN THE NORTHEAST TX PANHANDLE...AND IN THE LUBBOCK AREA. COOLING WILL OCCUR ALOFT THIS EVENING FROM WEST TO EAST WITH A CONCURRENT INCREASE IN MID LEVEL LAPSE RATES. THERE MAY BE A BRIEF WINDOW FOR SOME STORMS CAPABLE OF LARGE HAIL THIS EVENING IN NORTHWEST OK EAST OF THE SURFACE LOW CENTER WHERE LOW LEVEL MOISTURE WILL PERSIST A LITTLE LONGER THAN IN AREAS FURTHER SOUTH. OTHERWISE...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO EXIT THE CWA TO THE NORTHEAST BY SOMETIME EARLY TUESDAY MORNING. STRONG WEST WINDS ARE EXPECTED ON TUESDAY. SPEEDS MAY BE SOMEWHAT LIGHTER ACROSS NORTHERN OK WHERE CLOUDS ARE EXPECTED TO PERSIST FOR MUCH OF THE DAY...BUT MIXING WILL ALMOST CERTAINLY ALLOW FOR GUSTY WEST WINDS ACROSS SOUTHWESTERN PORTIONS OF THE CWA. INITIALIZED NAM WIND SPEEDS WERE JUDGED TO BE TOO LOW AND HAVE BEEN BUMPED UP. A TROUGH NOW MOVING ONTO THE COAST OF NORTHERN CA APPEARS TO HAVE ALREADY CLOSED OFF...AND SHOULD REACH THE SOUTHERN PLAINS ON WEDNESDAY. ALL MODELS SHOW THE LOW DEEPENING AS IT MOVES OUT OF THE ROCKIES...THEN MAKING A NORTHWARD TURN ONCE IT REACHES THE WESTERN PORTION OF THE CWA. SUCH A TRACK WOULD PLACE MUCH OF THE OUN CWA IN A DRY SLOT...WITH LOW RAIN CHANCES BUT WITH TEMPERATURES COOLER THAN TUESDAY. INITIALIZED POPS AND TEMPERATURES FOLLOW THIS TREND...AND WE LEFT THEM LARGELY UNCHANGED. WITH THE WEDNESDAY LOW MEANDERING AROUND TO THE NORTHEAST OF THE AREA...LOW PRECIP CHANCES CONTINUE THROUGH THE END OF THE WEEK. THE FORECAST BEYOND THURSDAY FROM THE PREVIOUS SHIFT HAS BEEN LEFT INTACT.
