THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF CENTRAL AND WESTERN OKLAHOMA THIS EVENING AND TONIGHT WEST OF A PONCA CITY TO WETUMKA TO MADILL LINE. A STRONG UPPER LEVEL SYSTEM WHICH WAS EXPECTED TO MOVE ACROSS OKLAHOMA THIS EVENING AND TONIGHT WAS LOCATED IN NORTHWESTERN ARIZONA AT 4 PM. EXTENSIVE CLOUDINESS AND RELATIVELY MILD CONDITIONS PREVAILED ACROSS MUCH OF CENTRAL AND WESTERN OKLAHOMA WHICH WAS RESULTING IN A MARGINALLY UNSTABLE ATMOSPHERE.

ACROSS THE EASTERN PORTION OF THE FORECAST AREA...FROM A BLACKWELL TO ARDMORE LINE EASTWARD.
