AREA...NORTHEAST OKLAHOMA.
ONSET...ONGOING.

DISCUSSION...
A MYRIAD OF OUTFLOW BOUNDARIES ARE ACTING ON STRONG INTSTABILITY
TO PRODUCE STRONG TO SEVERE THUNDERSTORMS ACROSS PRIMARILY NORTHEAST
OKLAHOMA AND THE NORTHWEST CORNER OF ARKANSAS THIS AFTERNOON.  THE
SHEAR IS RELATIVELY WEAK SO THE THUNDERSTORMS ARE OF A PULSE TO
WEAKLY ORGANIZED MULTICELL CHARACTER.  DAMAGING WINDS ARE THE
PRIMARY RISK BUT SOME HAIL WILL BE POSSIBLE.

THE THUNDERSTORMS ARE ALSO CAPABLE OF PRODUCING HEAVY RAIN. LOCALIZED
FLASH FLOODING WILL BE POSSIBLE.  IF THE THUNDERSTORMS ORGANIZE MORE
AS A COLD FRONT MOVE SOUTH INTO THE AREA FROM SOUTHERN KANSAS. FLASH
FLOODING COULD BE MORE WIDESPREAD.

THE THUNDERSTORMS ARE EXPECTED TO CONTINUE TO SPREAD SOUTH OVERNIGHT.
AS THE NIGHT PROGRESSES THE RISK FOR SEVERE THUNDERSTORMS SHOULD
DECREASE BUT THE RISK OF FLASH FLOODING WILL LIKELY INCREASE.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
ACTIVATION OF THE REGIONAL SPOTTER NETWORK EXPECTED.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...THUNDERSTORM POTENTIAL.
WEDNESDAY...NO HAZARDS.
THURSDAY...NO HAZARDS.
FRIDAY...NO HAZARDS.
SATURDAY...NO HAZARDS.
SUNDAY...NO HAZARDS.

EXTENDED DISCUSSION...
THE COLD FRONT WILL CONTINUE TO MOVE SOUTH ACROSS THE AREA
TUESDAY.  THUNDERSTORMS WILL LIKELY BE ONGOING AS THE MORNING
BEGINS.  FLASH FLOODING MAY STILL BE A RISK.  THE THUNDERSTORMS
ARE EXPECTED TO END FROM THE NORTH DURING THE DAY OR TUESDAY
NIGHT.

DRY WEATHER IS EXPECTED FOR THE REMAINDER OF THE UPCOMING WEEK
AS HIGH PRESSURE AT THE SURFACE AND ALOFT DOMINATE THE WEATHER.
