UPDATED OKLAHOMA THUNDERSTORM OUTLOOK NATIONAL WEATHER SERVICE OKLAHOMA CITY OK 745 PM CST MON MAR 31 1986 THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN NORTHWESTERN OKLAHOMA GENERALLY NORTH OF A LINE FROM PONCA CITY TO ARNETT TO BEAVER THIS EVENING. THUNDERSTORMS WILL MOVE INTO NORTHWESTERN OKLAHOMA WITHIN THE NEXT HOUR AND WILL SPREAD ACROSS ALL BUT SOUTHEASTERN OKLAHOMA BY SUNRISE. SOME OF THESE THUNDERSTORMS MAY PRODUCE LARGE HAIL AND WIND GUSTS IN EXCESS OF 60 MILES PER HOUR. A COLD FRONT EXTENDS FROM EXTREME SOUTHEASTERN NEBRASKA TO A WEAK LOW PRESSURE SYSTEM IN THE NORTHWESTERN CORNER OF THE TEXAS PANHANDLE THIS EVENING. A DRYLINE EXTENDS FROM THE LOW THROUGH THE EASTERN TEXAS PANHANDLE. THE POTENTIAL FOR THUNDERSTORM DEVELOPMENT ALONG THE DRYLINE HAS DIMINISHED WITH THE LOSS OF SURFACE HEATING. AN AREA OF WARM AIR ALOFT IN THE VICINITY OF THE DRYLINE THIS AFTERNOON WAS SOMEWHAT STRONGER THAN EXPECTED..AND NO THUNDERSTORM ACTIVITY DEVELOPED IN THAT AREA. HOWEVER..THUNDERSTORMS HAVE BEEN QUITE ACTIVE ALONG THE COLD FRONT NORTH OF OKLAHOMA. THIS COLD FRONT WILL MOVE ACROSS ALL BUT THE SOUTHEASTERN PART OF OKLAHOMA BY SUNRISE. THERE IS SUFFICIENT INSTABILITY AND MOISTURE TO SUPPORT THUNDERSTORM ACTIVITY ALONG THE FRONT DURING THE NIGHTTIME HOURS..ALTHOUGH THE POTENTIAL FOR SEVERE ACTIVITY WILL DIMINISH AFTER MIDNIGHT. GRADIENT WINDS BEHIND THE COLD FRONT ARE LIKELY TO GUST TO NEAR 50 MILES PER HOUR IN NORTH- WESTERN OKLAHOMA BUT WILL DIMINISH SOMEWHAT AS THE FRONT MOVES SOUTHEASTWARD. WE RECOMMEND THAT SPOTTER NETWORKS IN NORTHWESTERN OKLAHOMA REMAIN ON STANDBY FOR THE NEXT FEW HOURS. ANYONE WITH PROPERTY WHICH COULD BE DAMAGED BY STRONG WINDS SHOULD CONSIDER TAKING STEPS TO PROTECT IT BEFORE THE COLD FRONT ARRIVES.
