EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
130 PM CDT TUE JUN 08 1993

THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT IN EAST-CENTRAL AND SOUTHEAST OKLAHOMA.  THE HIGH RISK AREA
IS ALONG AND SOUTH OF A LINE FROM FORT SMITH TO MCALESTER.

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT IN THE REMAINDER OF EASTERN OKLAHOMA.

THUNDERSTORMS WHICH DEVELOPED JUST AHEAD OF THE DRY LINE THIS
MORNING IN SOUTHWEST OKLAHOMA AND NORTHWEST TEXAS HAVE CONTINUED TO
PROGRESS EASTWARD.  AT 1PM A LINE OF STRONG TO SEVERE THUNDERSTORMS
WAS MOVING THROUGH EAST-CENTRAL AND SOUTHEAST OKLAHOMA.  THE
ATMOSPHERE AHEAD OF THE LINE WAS VERY UNSTABLE AND WIND FIELDS
ALOFT ARE FAVORABLE FOR THESE STORMS TO REMAIN SEVERE.  LARGE HAIL
HAS ALREADY OCCURRED WITH STORMS AND AS THE AFTERNOON CONTINUES THE
THREAT FOR DAMAGING WINDS AND TORNADOES WILL INCREASE.  THE THREAT
IS THERE FOR WIDESPREAD SEVERE WEATHER IN THE HIGH RISK AREA WITH
TORNADOES A DEFINITE THREAT.

FURTHER NORTH...THE SITUATION HAS BEEN COMPLICATED BY THE STORMS IN
EAST-CENTRAL AND SOUTHEAST OKLAHOMA.  AT 1PM SATELLITE PICTURES
SHOWED A STRONG UPPER-LEVEL DISTURBANCE MOVING INTO NORTHWEST
OKLAHOMA.  THIS DISTURBANCE WILL TRACK NORTHEAST TO BE IN SOUTHEAST
KANSAS THIS EVENING AND WILL PROVIDE SIGNIFICANT LIFT AS IT MOVES
PAST NORTHEAST OKLAHOMA.  THIS LIFT WILL BE FOCUSED ON THE
DRYLINE...THAT AT 1PM EXTENDED FROM JUST EAST OF WICHITA...TO NEAR
ENID...TO NEAR ALTUS.  THIS DRYLINE WILL CONTINUE EASTWARD THIS
AFTERNOON AND STALL FROM SOUTHEAST KANSAS INTO SOUTHWEST OKLAHOMA.
THE AIR ALONG THE DRY LINE HAS RECOVERED RAPIDLY FROM THE EARLIER
RAIN-COOLED AIR AND HAS NOW BECOME EXTREMELY UNSTABLE.  RAPID
SEVERE THUNDERSTORM DEVELOPMENT IS EXPECTED EARLY THIS AFTERNOON
ALONG THE DRY LINE IN NORTH-CENTRAL OKLAHOMA AS THE UPPER-LEVEL
DISTURBANCE APPROACHES.  WIND FIELDS WITH THE DISTURBANCE ARE
STRONG AND FAVORABLE FOR SEVERE WEATHER.  ONCE DEVELOPED THE STORMS
WILL TRACK NORTHEAST TOWARD EASTERN OKLAHOMA.

THE QUESTION IN THE MODERATE RISK AREA IS HOW MUCH THE STORMS TO
THE SOUTH DISRUPT THE WIND FIELDS AND HOW MUCH SUN RETURNS TO THE
AREA TO DESTABILIZE THE ATMOSPHERE.  AT THIS TIME THERE APPEARS TO
BE ENOUGH OF A CHANCE FOR DESTABILIZATION TO WARRANT A MODERATE
RISK.  IF THE ATMOSPHERE FAILS TO DESTABILIZE FURTHER THEN THE
THREAT FOR SEVERE WEATHER WILL BE SIGNIFICANTLY REDUCED.

IF SEVERE THUNDERSTORMS DO ENTER THE MODERATE RISK LATER TODAY AND
TONIGHT THEN LARGE HAIL AND DAMAGING WINDS WOULD OCCUR...WITH THE
CHANCE OF AN ISOLATED TORNADO.

DURING THE NIGHT THE DRY LINE IS LIKELY TO AGAIN RETREAT WEST...BUT
A COLD FRONT WILL BE MOVING INTO NORTHWEST OKLAHOMA AND SOUTHEAST
KANSAS.  WITH THE ATMOSPHERE FORECAST TO REMAIN UNSTABLE INTO THE
NIGHT...THERE IS THE THREAT FOR SEVERE STORMS TO DEVELOP ALONG AND
AHEAD OF THE APPROACHING FRONT LATER TONIGHT.

EMERGENCY MANAGEMENT OFFICIALS AND SPOTTER GROUPS IN THE HIGH RISK
AREA SHOULD BE ACTIVATED NOW AS A TORNADO WATCH IS IN EFFECT FOR
THE HIGH RISK AREA.

EMERGENCY MANAGEMENT OFFICIALS AND SPOTTER GROUPS IN THE MODERATE
RISK AREA SHOULD CLOSELY MONITOR THE SITUATION AND BE READY FOR
ACTIVATION LATER TODAY OR TONIGHT.
