EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
810 PM CDT SUN APR 10 1994

SHORT TERM UPDATE...

AT 8PM A FRONTAL SYSTEM WAS STALLED ACROSS EASTERN OKLAHOMA FROM
NEAR WEST SILOAM SPRINGS IN DELAWARE COUNTY TO JUST SOUTH OF
HENRYETTA IN SOUTHERN OKMULGEE COUNTY.  THIS FRONT IS LIKELY TO
REMAIN ABOUT STATIONARY DURING THE NIGHT AS LOW PRESSURE IN EXTREME
SOUTHEAST NEW MEXICO BEGINS TO TRACK NORTHEAST...TO BE IN SOUTH
CENTRAL OKLAHOMA BY EARLY MONDAY.  AS THE LOW AND ASSOCIATED UPPER
LEVEL DISTURBANCE APPROACHES...THE WINDS ALOFT OVER EASTERN
OKLAHOMA WILL TEND TO INCREASE.

ALONG AND SOUTH OF THE STALLED FRONT THE AIR IS WARM AND VERY
UNSTABLE WITH TEMPERATURES AT EARLY EVENING IN THE UPPER 70S.  THIS
UNSTABLE AIR WAS BEING LIFTED OVER THE FRONT BY SOUTHERLY WINDS
JUST ABOVE GROUND LEVEL.  AS THIS FLOW OF AIR INCREASES AND THE
UPPER LEVEL DISTURBANCE APPROACHES DURING THE NIGHT...THUNDERSTORM
ACTIVITY WILL TEND TO INCREASE AGAIN DURING THE LATE EVENING AND
NIGHT TIME HOURS.  THIS INCREASE IN ACTIVITY WILL MOST LIKELY OCCUR
ALONG AND NORTH OF THE FRONT IN NORTHEAST OKLAHOMA.  THERE IS
HOWEVER SOME POTENTIAL FOR STORMS TO DEVELOP IN NORTH CENTRAL TEXAS
AND EFFECT SOUTHEAST OKLAHOMA LATE TONIGHT.

THE ATMOSPHERE IS EXPECTED TO REMAIN VERY UNSTABLE DURING THE
NIGHT.  THE INCREASING WINDS ALOFT WILL MAINTAIN A VERY FAVORABLE
WIND PROFILE.  THE RESULT WILL BE A CONTINUED POTENTIAL FOR SEVERE
WEATHER WITH ANY STORMS THAT FORM TONIGHT.  THE DEGREE OF
INSTABILITY AND FAVORABLE WIND PROFILE SUGGEST THAT TORNADOES WILL
BE POSSIBLE...ALONG WITH LARGE HAIL AND DAMAGING WINDS.

SPOTTERS IN NORTHEAST OKLAHOMA SHOULD REMAIN ON ALERTD AND SPOTTERS
IN SOUTHEAST OKLAHOMA SHOULD BE READY FOR ACTIVATION LATE TONIGHT.
