ARKANSAS...SOUTHWEST ARKANSAS...NORTH CENTRAL LOUISIANA...  
NORTHWEST LOUISIANA...SOUTHEAST OKLAHOMA...EAST TEXAS AND  
NORTHEAST TEXAS.  
   
DAY ONE...TODAY AND TONIGHT
 
 
SHOWERS AND THUNDERSTORMS WILL INCREASE ACROSS THE REGION  
TODAY...AHEAD OF A STRONG UPPER LEVEL DISTURBANCE THAT WILL LIFT  
NORTHEAST ACROSS THE AREA THIS AFTERNOON AND TONIGHT. DAYTIME  
HEATING WILL HELP TO DESTABLIZE THE AIR MASS AHEAD OF THIS  
DISTURBANCE...ESPECIALLY OVER DEEP EAST TEXAS...NORTH LOUISIANA  
AND SOUTHWEST ARKANSAS...AS STRONG SHEAR AND FORCING ALOFT AHEAD  
OF THIS DISTURBANCE SPREADS INTO THE REGION. ISOLATED TO SCATTERED  
SEVERE THUNDERSTORMS ARE POSSIBLE...WITH DAMAGING WINDS AND  
ISOLATED TORNADOES POSSIBLE. HOWEVER...THE PRIMARY THREAT FROM  
THESE THUNDERSTORMS WILL BE LOCALLY HEAVY RAINFALL...WHICH WILL  
FALL OVER GROUNDS THAT STILL REMAIN SATURATED FROM EXCESSIVE  
RAINFALL THAT FELL EARLIER THIS PAST WEEK. ONE TO THREE INCHES OF  
RAIN...WITH ISOLATED HIGHER AMOUNTS...WILL BE POSSIBLE...WHICH  
WILL CONTRIBUTE TO INCREASED RUNOFF AND THE POTENTIAL FOR FLASH  
FLOODING. THE HEAVY RAIN AND ISOLATED SEVERE THUNDERSTORM THREAT WILL  
DIMINISH FROM WEST TO EAST THIS EVENING...ALTHOUGH SCATTERED  
SHOWERS AND THUNDERSTORMS WILL PERSIST OVERNIGHT MAINLY OVER DEEP  
EAST TEXAS AND NORTH LOUISIANA.  
   
DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
 
 
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE ONCE AGAIN  
MONDAY AFTERNOON AND EVENING OVER THE REGION...AHEAD OF ANOTHER  
STRONG UPPER LEVEL DISTURBANCE THAT WILL MOVE INTO THE SOUTHERN  
PLAINS. DAYTIME HEATING WILL CONTRIBUTE TO AIR MASS DESTABILIATION  
MONDAY AFTERNOON...SUCH THAT SCATTERED SEVERE THUNDERSTORMS  
CAPABLE OF PRODUCING DAMAGING WINDS AND ISOLATED TORNADOES WILL BE  
POSSIBLE OVER EAST TEXAS...SOUTHWEST ARKANSAS...AND NORTH  
LOUISIANA. HOWEVER...THE PRIMARY THREAT WILL AGAIN BE LOCALLY  
HEAVY RAINFALL...WITH ADDITIONAL AMOUNTS OF TWO TO IN EXCESS OF FOUR  
INCHES LIKELY. THIS WILL RESULT IN RAPID RUNOFF AND ENHANCE THE  
POTENTIAL FOR FLASH FLOODING OVER MUCH OF THE REGION.  
 
THE HEAVY RAINFALL THREAT WILL DIMINISH TUESDAY MORNING WITH THE  
DEPARTURE OF THIS DISTURBANCE. SCATTERED SHOWERS AND THUNDERSTORMS  
WILL REMAIN POSSIBLE WEDNESDAY THROUGH SATURDAY.  
   
SPOTTER INFORMATION STATEMENT
