PUBLIC SEVERE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1140 AM CDT TUE APR 24 2007

...AN OUTBREAK OF SEVERE THUNDERSTORMS IS EXPECTED OVER PARTS OF THE
CENTRAL AND SOUTHERN PLAINS THIS AFTERNOON AND TONIGHT...

THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE
DEVELOPMENT OF A FEW STRONG TORNADOES AND DESTRUCTIVE HAIL OVER
PARTS OF THE CENTRAL AND SOUTHERN PLAINS THIS AFTERNOON AND TONIGHT.

THE AREAS MOST LIKELY TO EXPERIENCE THIS ACTIVITY INCLUDE

WESTERN ARKANSAS
CENTRAL AND EASTERN KANSAS
FAR WESTERN MISSOURI
WEST CENTRAL THROUGH EASTERN OKLAHOMA
PARTS OF CENTRAL AND EASTERN TEXAS

SURROUNDING THE GREATEST RISK AREA...THERE IS A SLIGHT RISK OF
SEVERE THUNDERSTORMS FROM THE CENTRAL PLAINS INTO THE LOWER OHIO
VALLEY AND SOUTHWARD INTO SOUTHERN TEXAS

AN INTENSE UPPER LEVEL STORM SYSTEM OVER SOUTHERN COLORADO AND
NORTHERN NEW MEXICO WILL MOVE EAST INTO THE CENTRAL AND SOUTHERN
PLAINS THIS AFTERNOON...ACCOMPANIED BY AN 80-90 KT MID LEVEL JET
STREAK. SURFACE LOW PRESSURE WILL DEEPEN AS IT MOVES ACROSS
SOUTHWEST KANSAS AND THE OKLAHOMA PANHANDLE THIS AFTERNOON. A
PACIFIC FRONT SEPARATING MOIST UNSTABLE AIR TO THE EAST AND DRIER
AIR TO THE WEST IS EXPECTED TO STALL/BECOME STATIONARY ACROSS
WESTERN OR CENTRAL OKLAHOMA...LIKELY JUST WEST OF THE INTERSTATE 35
CORRIDOR. TO THE EAST OF THE BOUNDARY...SURFACE DEWPOINTS WILL BE IN
THE 60S AND 70S FROM SOUTH CENTRAL KANSAS SOUTHWARD THROUGH TEXAS.
THESE VERY HIGH DEWPOINTS WILL CONTRIBUTE TO VERY UNSTABLE
CONDITIONS THIS AFTERNOON.

STRONG TO SEVERE THUNDERSTORMS HAVE ALREADY DEVELOPED FROM SOUTHWEST
OKLAHOMA THROUGH WESTERN PORTIONS OF NORTH CENTRAL TEXAS. THIS
INITIAL LINE OF STORMS WILL HAVE THE POTENTIAL FOR LARGE
HAIL...DAMAGING WINDS AND TORNADOES. GIVEN THE STRENGTHENING
VERTICAL WIND SHEAR AND DEGREE OF INSTABILITY...THE POTENTIAL WILL
INCREASE THIS AFTERNOON FOR SUPERCELLS CAPABLE OF
LARGE...DESTRUCTIVE HAIL AND TORNADOES...SOME OF WHICH COULD BE
STRONG.

TONIGHT...THE POTENTIAL FOR SIGNIFICANT SEVERE WEATHER...INCLUDING
TORNADOES...IS FORECAST TO SPREAD EAST THROUGH EASTERN PARTS OF
KANSAS...OKLAHOMA...AND TEXAS...EVENTUALLY IMPACTING LOCATIONS
THROUGH THE ARKLATEX.

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 TODAY.
