145 PM CDT MON APR 11 1994

...MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT
   FOR MUCH OF EASTERN OKLAHOMA...

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT FOR A LARGE PART OF EASTERN OKLAHOMA.  THE AREA INCLUDES
THAT PART OF EASTERN OKLAHOMA SOUTH AND EAST OF INTERSTATE 44.

THERE IS ALSO A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR THE
REMAINDER OF EASTERN OKLAHOMA...INCLUDING THOSE COUNTIES NORTH OF
INTERSTATE 44.

AT 1 PM...A STATIONARY FRONT EXTENDED FROM NORTHERN ARKANSAS ACROSS
EASTERN OKLAHOMA TO NEAR SEMINOLE.  A COLD FRONT EXTENDED SOUTHWARD
TO NEAR ARDMORE.  MOIST SOUTHERLY WINDS WILL CONTINUE TO PUSH
UNSTABLE AIR NORTH OF THE STATIONARY FRONT...RESULTING IN
STRONG...AND POSSIBLY SEVERE THUNDERSTORMS.

FARTHER SOUTH...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG AND
AHEAD OF THE COLD FRONT AND MOVE RAPIDLY NORTHEASTWARD.  WARM
TEMPERATURES AND HIGH HUMIDITIES EAST OF THE COLD FRONT...AND SOUTH
OF THE STATIONARY FRONT...WILL PROVIDE SUFFICIENT CONDITIONS FOR
THE DEVELOPMENT OF STRONG TO SEVERE THUNDERSTORMS IN THAT AREA.  IN
ADDITION...STRONG WINDS ALOFT WILL PROVIDE FAVORABLE CONDITIONS FOR
POSSIBLE TORNADO DEVELOPMENT FROM A FEW OF THE STRONGEST
THUNDERSTORMS.

THE MAIN THREAT FOR SEVERE WEATHER NORTH OF INTERSTATE 44 WILL BE
LARGE HAIL...ALTHOUGH DAMAGING WINDS WILL BE POSSIBLE.  SOUTH OF
INTERSTATE 44...LARGE HAIL AND DAMAGING WINDS WILL ALSO BE
POSSIBLE.  HOWEVER...CONDITIONS  WILL ALSO BE FAVORABLE FOR THE
DEVELOPMENT OF TORNADOES FROM THE STRONGEST THUNDERSTORMS...DUE TO
STRONG WINDS ALOFT.

IF SPOTTERS HAVE NOT ALREADY BEEN ACTIVATED...THEY SHOULD CLOSELY
MONITOR WEATHER CONDITIONS FOR POSSIBLE ACTIVATION LATER THIS
AFTERNOON AND EARLY TONIGHT.
