THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS  
MUCH OF EASTERN OKLAHOMA.  
   
DAY ONE
 
TODAY AND TONIGHT.  
 
SEVERE THUNDERSTORM.  
RISK...LIMITED.  
AREA...EASTERN OKLAHOMA AND WESTERN ARKANSAS.  
ONSET...ONGOING.  
 
DISCUSSION...  
SHOWERS AND THUNDERSTORMS CONTINUE EARLY THIS MORNING ACROSS  
EASTERN OKLAHOMA. THE MAIN THREAT WITH THESE STORMS WILL BE STRONG  
OR DAMAGING WIND GUSTS. THE SEVERE POTENTIAL FOR THIS AFTERNOON  
MAY BE MORE LIMITED IN AREAS THAT HAD RAIN OVERNIGHT. THE HIGHER  
SEVERE POTENTIAL WILL LIKELY BE ACROSS FAR SOUTHEAST OKLAHOMA. AN  
OUTFLOW BOUNDARY EXTENDED FROM ROUGHLY GAINESVILLE TO ATOKA, AND  
THIS COULD SERVE AS A FOCUS FOR STORM DEVELOPMENT LATER TODAY.  
OTHERWISE, MAIN HAZARDS WITH ONGOING STORMS WILL BE BRIEF HEAVY  
RAINFALL, GUSTY WINDS AND LIGHTNING. STORM CHANCES WILL DIMINISH  
BY THIS AFTERNOON THROUGH TONIGHT.  
 
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...  
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.  
   
DAYS TWO THROUGH SEVEN
 
MONDAY THROUGH SATURDAY.  
MONDAY THROUGH SATURDAY...THUNDERSTORM POTENTIAL.  
 
EXTENDED DISCUSSION...  
COLD FRONT FINALLY WILL MOVE SOUTH OF THE AREA BY MONDAY, BRINGING  
SOME COOLER AND MORE STABLE AIR TO THE REGION. SOUTHWEST FLOW  
ALOFT WILL CONTINUE THROUGH AT LEAST MID WEEK, SO ANY LOW  
AMPLITUDE IMPULSE COULD GENERATE SOME SHOWERS AND STORMS. HOWEVER  
THE OVERALL SEVERE POTENTIAL WILL REMAIN LOW FOR THE NEXT SEVERAL  
DAYS.
