What happened
The episode as NWS OUN wrote it up.
An early morning non-severe thunderstorm caused two fires at the Wynnewood Refinery. The first fire occurred in a tank housing naptha, a gasoline component. This fire was thought to be contained, before another fire began that evening in a tank containing diesel fuel. Approximately 70,000 barrels of naptha and diesel were lost in the two day fire. Roads surrounding the refinery were closed due to the massive amounts of smoke coming from the refinery. No injuries were reported with the explosions. The fire burned for at least 2 days before finally extinguishing. Monetary damage amounts were estimated.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 1137 AM CDT FRI APR 27 2007 .DISCUSSION... THERE IS ENOUGH ELEVATED INSTABILITY TODAY THAT SOME ISOLATED STRONG THUNDERSTORMS HAVE DEVELOPED. WE MAY SEE SOME MARGINALLY SEVERE STORMS WITH THIS CURRENT AREA. FARTHER SOUTHWEST... SUNSHINE WILL ALLOW CONTINUED WARMING AND MAY ALSO SEE A SLIGHT INCREASE IN MOISTURE TO FURTHER DESTABILIZE THE AREA AND SO ISOLATED SEVERE STORMS MAY POSSIBLY DEVELOP LATER TODAY AS WELL... BUT SHOULD NOT BE VERY WIDESPREAD. WILL ALSO LOOK FOR THE CHANCE OF REDEVELOPMENT ALONG THE SURFACE FRONT IN NORTHWEST OKLAHOMA WHERE SOME CU IS BEGINNING TO DEVELOP. MAIN UPDATE TO THE PACKAGE IS THE POP DISTRIBUTION PER RADAR TRENDS. && .PREV DISCUSSION... /ISSUED 427 AM CDT FRI APR 27 2007/ DISCUSSION... SCATTERED SHOWERS AND AN ISOLATED THUNDERSTORM OR TWO CONTINUE TO PROGRESS SOUTHEASTWARD AHEAD OF MID-LEVEL S/WV THAT WILL MAKE ITS WAY ACROSS THE REGION TODAY AND THIS EVENING. GIVEN OBSERVATIONAL DATA EARLY THIS MORNING...APPEARS NAM HAS A BETTER HANDLE ON STRENGTH OF SYSTEM...AS IT HAS A BIT HIGHER AMPLITUDE THAN GFS. MOISTURE WILL BE AN IMPORTANT PARAMETER ON DETERMINING HOW WIDESPREAD AND HOW STRONG ANY THUNDERSTORMS BECOME LATER TODAY. NAM APPEARS TO HAVE A BETTER HANDLING OF BOUNDARY LAYER MOISTURE CONTENT THROUGHOUT THE DAY TODAY AS IT PROGS MID-UPPER 50S AS OPPOSED TO THE MID-UPPER 60S FROM THE GFS. THIS WILL RESULT IN MOST OF THE ACTIVITY BEING QUITE ELEVATED IN NATURE...ALTHOUGH LOWER LEVEL BASED DEEP CONVECTION POSSIBLE THIS AFTERNOON AND EVENING NEAR WEAK FRONTAL BOUNDARY THAT WILL ACCOMPANY THE S/WV TROF. ISOLATED SEVERE STORMS POSSIBLE ACROSS MAINLY SOUTHERN OKLAHOMA AND WESTERN NORTH TEXAS THIS AFTERNOON WHEN INSTABILITY PEAKS. DEEP-LAYER SHEAR WILL SUPPORT SUPERCELL FORMATION WITH LARGE HAIL POSSIBLE. GIVEN RUC/NAM FORECAST SOUNDINGS...SOME STRONG WINDS WILL ALSO BE POSSIBLE WITH DEPTH OF LOWER-LEVEL DRY AIR. S/WV RIDGING WILL DOMINATE WEATHER SATURDAY AND SUNDAY WITH PLENTY OF SUN AND RELATIVELY LIGHT WINDS EXPECTED. THE WINDS WILL BEGIN TO PICK UP SUNDAY AFTERNOON AS NEXT SYSTEM APPROACHES FROM THE SOUTHWEST. TODAYS SYSTEM WILL NOT SCOUR MOISTURE TOO FAR SOUTH...SO AMPLE MOISTURE RETURN IS EXPECTED FOR THE EARLY AND MIDDLE PORTIONS OF NEXT WEEK. FAIRLY DECENT AGREEMENT AMONG MEDIUM RANGE MODELS THROUGH MID-WEEK...BRINGING STRONG S/WVS THROUGH THE REGION MONDAY THROUGH AT LEAST WEDNESDAY...WHEN TIMING BECOMES MORE OF AN ISSUE.
