NATIONAL WEATHER SERVICE TULSA OK
600 AM CDT THU JUN 28 2001

...ISOLATED SEVERE THUNDERSTORMS LIKELY ACROSS EASTERN OKLAHOMA AND
   NORTHWEST ARKANSAS TODAY AND TONIGHT...

UPPER LEVEL LOW PRESSURE WILL CONTINUE MOVING SLOWLY SOUTHWESTWARD
TODAY ACROSS SOUTHERN MISSOURI. SHOWERS AND THUNDERSTORMS HAVE
ALREADY DEVELOPED THIS MORNING ACROSS PORTIONS OF EASTERN OKLAHOMA.
SHOWERS AND THUNDERSTORMS WILL CONTINUE THROUGH THE MORNING HOURS
ACROSS THIS AREA. THESE STORMS WILL BE CAPABLE OF PRODUCING HAIL TO
THE SIZE OF DIMES AND VERY HEAVY RAIN.

ISOLATED SEVERE THUNDERSTORMS ARE LIKELY THIS AFTERNOON AND EVENING
ACROSS ALL OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS. THESE STORMS
WILL BE CAPABLE OF PRODUCING HAIL TO THE SIZE OF NICKELS AND WIND
GUSTS TO 65 MPH.

AS THE LOW LEVEL JET STRENGTHENS TONIGHT...SCATTERED THUNDERSTORMS
WILL AGAIN DEVELOP ACROSS EASTERN OKLAHOMA. SOME OF THESE STORMS
COULD BRIEFLY REACH SEVERE LIMITS...PRODUCING DIME SIZE HAIL AND
VERY HEAVY RAIN. BECAUSE THESE STORMS MAY DEVELOP INTO A CONVECTIVE
BAND AND MOVE OVER THE SAME AREAS OVERNIGHT...LOCALIZED FLOODING
WILL BE POSSIBLE.

.DAY TWO...ISOLATED SEVERE THUNDERSTORMS ARE AGAIN EXPECTED ON
FRIDAY OVER EASTERN OKLAHOMA AND NORTHWEST ARKANSAS AS THE
UPPER LEVEL LOW PRESSURE SYSTEM MOVES SLOWLY SOUTHWEST INTO THE
AREA.

.SPOTTER ACTIVATION...
ACTIVATION OF STORM SPOTTERS MAY BE NECESSARY ACROSS PORTIONS OF
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS BEGINNING THIS MORNING.

.DISCUSSION...
LIFTED INDICES ACROSS EASTERN OKLAHOMA THIS MORNING RANGE FROM -2 TO
-4 DEGREE C. ALTHOUGH INSTABILITIES ARE MARGINAL...A FEW STORMS THIS
MORNING MAY BRIEFLY REACH SEVERE LIMITS...PRODUCING DIME SIZE HAIL.

AN UPPER LEVEL LOW PRESSURE SYSTEM WILL CONTINUE TO DRIFT SLOWLY
SOUTHWESTWARD THIS AFTERNOON. COOLER TEMPERATURES ALOFT ASSOCIATED
WITH UPPER LOW...COMBINED WITH SURFACE HEATING WILL CREATE A
MODERATELY UNSTABLE ATMOSPHERE BY EARLY AFTERNOON WITH CAPE VALUES
IN THE 2000-2500 J/KG RANGE. THERMODYNAMIC PROFILES/SHEAR PROFILES
SUPPORT LARGE HAIL AND DAMAGING WINDS WITH THE STRONGER CELLS.

SHOWERS AND THUNDERSTORMS ARE AGAIN EXPECTED TO DEVELOP OVER EASTERN
OKLAHOMA TONIGHT WHERE STRONG ISENTROPIC LIFT WILL BE PRESENT. DIME
SIZE HAIL AND VERY HEAVY RAIN WILL BE THE PRIMARILY THREAT WITH ANY
SEVERE STORMS THAT DEVELOP. IN ADDITION IF STORMS MOVE OVER THE SAME
AREAS...LOCALIZED FLOODING WILL LIKELY OCCUR.
