EASTERN OKLAHOMA/NORTHWEST ARKANSAS HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
100 PM CDT TUE MAY 26 1998

NO SEVERE THUNDERSTORMS ARE EXPECTED ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS THIS AFTERNOON OR TONIGHT.

THE AREA OF RAIN AND THUNDERSTORMS WHICH MOVED ACROSS EASTERN OKLAHOMA
AND NORTHWEST ARKANSAS THIS MORNING HAS MOVED EAST OF THE REGION AS OF
1PM THIS AFTERNOON.  THE UPPER-LEVEL STORM SYSTEM THAT WAS RESPONSIBLE
FOR THIS ACTIVITY WAS MOVING EASTWARD ACROSS NORTHEAST OKLAHOMA AT
MIDDAY. NUMEROUS OUTFLOW BOUNDARIES WERE PRESENT OVER THE AREA...BUT THE
MOST WELL-DEFINED BOUNDARY WAS LOCATED OVER FAR SOUTHEAST OKLAHOMA TO
THE SOUTH OF MCALESTER.

THE MOST LIKELY PLACE FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON AND
EVENING WILL BE ALONG THE RED RIVER IN EXTREME SOUTHEAST
OKLAHOMA...WHERE A MODERATE AMOUNT INSTABILITY EXISTS.  SCATTERED
THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THIS BOUNDARY THIS AFTERNOON
PRIMARILY IN CHOCTAW AND PUSHMATAHA COUNTIES.  THE STRONGEST STORMS MAY
BE CAPABLE OF PRODUCING SOME SMALL HAIL AND GUSTY WINDS...BUT THEY
SHOULD REMAIN BELOW SEVERE LEVELS.

LARGE-SCALE SUBSIDENCE IN THE WAKE OF THE UPPER-LEVEL STORM SYSTEM WILL
PREVENT THE DEVELOPMENT OF THUNDERSTORMS OVER MOST OF THE REMAINDER OF
EASTERN OKLAHOMA THIS AFTERNOON.  HOWEVER WITH OUTFLOW BOUNDARIES IN THE
AREA...WIDELY SCATTERED SHOWERS AND THUNDERSTORMS MAY STILL DEVELOP THIS
AFTERNOON AND EARLY THIS EVENING AHEAD OF THE STORM SYSTEM OVER EXTREME
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.  WEAK WIND FIELDS AND
DECREASING INSTABILITY WILL PREVENT ANY THUNDERSTORMS THAT DEVELOP FROM
BECOMING SEVERE.
