EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
130 PM CDT SAT MAY 8 1993

A SEVERE THUNDERSTORM WATCH IS IN EFFECT FOR MOST OF EASTERN OKLAHOMA
UNTIL 4 PM. THE ONLY COUNTIES NOT INCLUDED IN THIS WATCH ARE LATIMER...
LEFLORE AND MCCURTAIN.

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS ALL OF EASTERN
OKLAHOMA THIS AFTERNOON AND TONIGHT.

AN OUTFLOW BOUNDARY EXTENDED FROM VINITA TO TULSA TO BRISTOW TO MIDWEST
CITY EARLY THIS AFTERNOON AND HAD BECOME NEARLY STATIONARY. TO THE
SOUTH OF THIS BOUNDARY...THE AIRMASS HAS BECOME EXTREMELY UNSTABLE AS
TEMPERATURES HAVE WARMED INTO THE MID 70S TO LOWER 80S. TO THE NORTH OF
THE BOUNDARY...SHOWERS AND THUNDERSTORMS WERE WIDESPREAD AND
TEMPERATURES WERE IN THE UPPER 50S TO LOWER 60S.

THE OUTFLOW BOUNDARY IS NOT EXPECTED TO MOVE MUCH FARTHER SOUTH THIS
AFTERNOON AND MAY EVEN MOVE SLOWLY NORTH. THUNDERSTORMS ARE EXPECTED TO
DEVELOP AND INTENSIFY ALONG AND SOUTH OF THIS BOUNDARY THIS AFTERNOON.
THE EXTREME INSTABILITY SUGGESTS THAT STORMS WILL QUICKLY BECOME
SEVERE AND PRODUCE LARGE HAIL AND DAMAGING WINDS. THE VERTICAL WIND
PROFILE IS ALSO QUITE FAVORABLE FOR A FEW STRONG DAMAGING TORNADOES
THIS AFTERNOON AND TONIGHT ACROSS EASTERN OKLAHOMA.

AS THUNDERSTORMS BECOME MORE NUMEROUS BY THIS EVENING...THE OUTFLOW
BOUNDARY WILL LIKELY BEGIN MOVING BACK TO THE SOUTH. IF THIS OCCURS...
THE MAIN SEVERE WEATHER THREAT WILL SHIFT INTO SOUTHEAST OKLAHOMA BY
LATER TONIGHT. FLASH FLOODING IS ALSO A POSSIBILITY THIS AFTERNOON AND
TONIGHT AS SOME AREAS MAY RECEIVE SEVERAL PERIODS OF THUNDERSTORMS. THE
POTENTIAL EXISTS FOR SOME LOCATIONS TO RECEIVE AS MUCH AS 4 INCHES OF
RAIN THIS AFTERNOON AND TONIGHT. THIS AMOUNT OF RAINFALL WILL LIKELY
RESULT IN FLASH FLOODING OF LOW LYING AREAS.

EMERGENCY MANAGEMENT OFFICIALS AND STORM SPOTTERS ARE EXPECTED TO BE
ACTIVATED THIS AFTERNOON AND TONIGHT.
