...SEVERE THUNDERSTORMS EXPECTED OVER PRIMARILY OKLAHOMA THIS
AFTERNOON AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF TORNADOES...LARGE HAIL AND DAMAGING WINDS OVER
PRIMARILY OKLAHOMA THIS AFTERNOON AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

PARTS OF WESTERN ARKANSAS
MUCH OF OKLAHOMA
SMALL PART OF NORTHERN TEXAS

ELSEWHERE...SEVERE STORMS ARE ALSO POSSIBLE ACROSS MUCH OF THE
SOUTHERN PLAINS.

STRONG SOUTHERLY FLOW HAS TRANSPORTED A VERY MOIST AND UNSTABLE AIR
MASS NORTHWARD INTO OKLAHOMA AHEAD OF A LOW PRESSURE SYSTEM
APPROACHING FROM NEW MEXICO. WHILE THERE HAVE BEEN SEVERE
THUNDERSTORMS MUCH OF THE NIGHT ACROSS THE NORTHERN TEXAS PANHANDLE
INTO NORTHWEST OKLAHOMA...DAYTIME HEATING AND THE INCREASING WIND
SHEAR WILL LEAD TO DEVELOPMENT OF WIDESPREAD SEVERE THUNDERSTORMS BY
LATER THIS AFTERNOON.

AT THIS TIME STORM DEVELOPMENT IS EXPECTED TO INCREASE ACROSS
NORTHERN AND WESTERN OKLAHOMA BY MID AFTERNOON AND QUICKLY BECOME
SEVERE. CONDITIONS WILL BE FAVORABLE FOR LARGE SUPERCELL
THUNDERSTORMS WHICH WILL INCLUDE A THREAT OF NOT ONLY TORNADOES BUT
VERY LARGE HAIL AND DAMAGING WINDS.

THERE IS THE POSSIBILITY THAT TORNADOES COULD BECOME STRONG AND THE
HAIL VERY LARGE WITH THE MOST INTENSE SUPERCELLS AS THEY MOVE
EASTWARD ACROSS CENTRAL INTO EASTERN OKLAHOMA LATER THIS AFTERNOON
AND EVENING.

IN ADDITION DAMAGING WINDS WILL BE POSSIBLE WITH THE STRONGEST
STORMS AND THIS THREAT WILL CONTINUE WELL INTO THE EARLY NIGHTTIME
HOURS EASTWARD INTO WESTERN ARKANSAS.

SITUATION. THOSE IN THE THREATENED AREA ARE URGED TO REVIEW SEVERE
WEATHER SAFETY RULES AND TO LISTEN TO RADIO...TELEVISION...AND NOAA
WEATHER RADIO FOR POSSIBLE WATCHES...WARNINGS...AND STATEMENTS LATER
