OKZ026>034-040-121200- EASTERN OKLAHOMA THUNDERSTORM OUTLOOK NATIONAL WEATHER SERVICE TULSA OK 140 PM CDT MON MAY 11 1992 THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT IN EASTERN OKLAHOMA ALONG AND SOUTHWEST OF A LINE FROM THE KANSAS BORDER NORTH OF BARTLESVILLE TO TULSA TO MUSKOGEE TO THE ARKANSAS LINE AT FORT SMITH. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE REMAINDER OF NORTHEAST OKLAHOMA THIS EVENING AND TONIGHT. THE MORNING THUNDERSTORMS HAVE ESTABLISHED A BOUNDARY FROM JUST SOUTH OF FORT SMITH TO JUST SOUTH OF MCALESTER TO BETWEEN ARDMORE AND OKLAHOMA CITY. IN ADDITION A DRY LINE WAS ADVANCING INTO WESTERN OKLHAOMA. THUNDERSTORMS ARE NOW RAPIDLY DEVELOPING NORTHWEST OF OKLAHOMA CITY NEAR WHERE THE THUNDERSTORM BOUNDARY MEETS THE ADVANCING DRY LINE. THESE THUNDERSTORMS ARE EXPECTED TO RAPIDLY BECOME SEVERE AND WILL DEVELOP EASTWARD ALONG THE BOUNDARY INTO SOUTHEAST OKLAHOMA. OTHER THUNDERSTORMS SHOULD SOON DEVELOP ALONG THE DRY LINE FROM NEAR MEDICINE LODGE KANSAS SOUTHWARD INTO OKLAHOMA. THESE STORMS TOO WILL QUICKLY BECOME SEVERE. THE ATMOSPHERE ALONG AND SOUTH OF THE THUNDERSTORM BOUNDARY HAS BECOME EXTREMELY UNSTABLE WITH A FAVORABLE WIND PROFILE. TORNADOES WILL BE DEFINITE THREAT WITH THE THUNDERSTORMS AS THEY TRACK ALONG THE BOUNDARY INTO SOUTHEAST OKLAHOMA...LARGE HAIL AND STRONG STRAIGHT-LINE WINDS WILL ALSO ACCOMPANY THE STORMS. THE ATMOSPHERE AHEAD OF THE DRY LINE IN NORTH-CENTRAL OKLAHOMA IS MODERATELY UNSTABLE AND MAY DESTABILIZE FURTHER THIS AFTERNOON AS THE CLOUDS AHEAD OF THE THUNDERSTORMS ARE BREAKING UP AND ALLOWING SOME SUNSHINE. THE WIND PROFILE ACROSS NORTHERN OKLAHOMA IS ALSO FAVORABLE FOR SEVERE THUNDERSTORMS. TORNADOES WILL BE A POSSIBILITY IN THE MODERATE RISK AREA OVER NORTHEAST OKLAHOMA AS THE STORMS THAT FORM NEAR THE DRY LINE MOVE EASTWARD. THE ATMOSPHERE IN THE SLIGHT RISK AREA REMAINS RAIN-COOLED AND STABLE AT EARLY AFTERNOON. THE PARTIAL CLEARING NOW OCCURRING AHEAD OF THE DRY LINE MAY WORK INTO NORTHEAST OKLAHOMA LATE THIS AFTERNOON AND ALLOW THE ATMOSPHERE TO DESTABILIZE. THIS...ALONG WITH THE FAVORABLE WIND PROFILE MAY RESULT IN ONE OR TWO OF THE THUNDERSTORMS REMAINING SEVERE TONIGHT AS THEY TRACK INTO THE SLIGHT RISK AREA. THE UPPER-AIR SYSTEM THAT WAS OVER EXTREME SOUTHWEST KANSAS AT EARLY AFTERNOON WAS SUPPORTING THE RAPID STORM DEVELOPMENT. THIS SYSTEM SHOULD BE EAST OF OKLAHOMA BY AROUND 1AM AND SHOULD DIMINISH THE SEVERE WEATHER THREAT AT THAT TIME. SPOTTERS IN THE MODERATE RISK AREA SHOULD BEGIN TO ACTIVATE NOW AS TORNADO WATCHES ARE BEING POSTED. SPOTTERS IN THE SLIGHT RISK AREA SHOULD BE READY FOR ACTIVATION THIS EVENING AND TONIGHT.
