AREAS AFFECTED...SERN OK THROUGH NERN TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 061906Z - 062100Z

THUNDERSTORMS ARE EXPECTED TO DEVELOP BY 20-21Z OVER SERN OK AND
SPREAD SEWD INTO NERN TX. THE STRONGER STORMS WILL BE CAPABLE OF
PRODUCING LARGE HAIL AND DAMAGING WIND GUSTS. AREA WILL CONTINUE TO
BE MONITORED FOR A POSSIBLE WW.

THIS AFTERNOON AN OUTFLOW BOUNDARY LOCATED JUST S OF MCALESTER OK IS
MOVING SEWD. DESTABILIZATION IS OCCURRING S OF THIS BOUNDARY. FULL
SUN AND UPPER 60S DEWPOINTS WILL RESULT IN MODERATE INSTABILITY. AN
MCV CONTINUES MOVING SEWD THROUGH ERN OK WITH A 40 KT NWLY MID LEVEL
JET LOCATED ALONG THE SRN PERIPHERY OF THE MCV. TEMPERATURES ARE
WARMING TO NEAR 90 OVER SERN OK AND NERN TX AND SUGGEST THE CAP IS
BECOMING WEAK ENOUGH FOR STORM TO DEVELOP WITHIN ZONE OF ASCENT
ASSOCIATED WITH SEWD MOVING MCV AND OUTFLOW BOUNDARY. THE LOW LEVEL
JET HAS WEAKENED. HOWEVER...LIGHT SLY BOUNDARY LAYER FLOW VEERING TO
NWLY AND INCREASING TO 40 KT AT 500 MB WILL CONTRIBUTE TO FAVORABLE
0-6 KM VERTICAL SHEAR PROFILES FOR ORGANIZED STORMS INCLUDING
POTENTIAL FOR A SUPERCELL OR TWO.
