DISCUSSION...  
SOUTHERLY WINDS WILL CONTINUE TO GUST TO AROUND 30 MILES AN HOUR  
AT TIMES TONIGHT. THIS WILL MAINTAIN A LIMITED FIRE DANGER THROUGH  
THE OVERNIGHT HOURS DESPITE INCREASING HUMIDITY VALUES.  
 
LATE TONIGHT...THUNDERSTORM CHANCES WILL BEGIN TO INCREASE ACROSS  
PARTS OF EASTERN OKLAHOMA AHEAD OF AN APPROACHING DRYLINE AND  
UPPER LEVEL STORM SYSTEM. STORMS LATE TONIGHT ARE NOT EXPECTED TO  
BE SEVERE...HOWEVER COVERAGE OF THUNDERSTORMS AND SEVERE  
POTENTIAL WILL INCREASE DURING THE DAY FRIDAY.  
 
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...  
SPOTTER ACTIVATION NOT EXPECTED.  
   
DAYS TWO THROUGH SEVEN
 
FRIDAY THROUGH WEDNESDAY.  
FRIDAY...THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL...HEAVY RAIN  
POTENTIAL...FIRE WEATHER POTENTIAL.  
SATURDAY...THUNDERSTORM POTENTIAL.  
SUNDAY...SEVERE THUNDERTORM POTENTIAL...HIGH WIND POTENTIAL.  
MONDAY THROUGH WEDNESDAY...THUNDERSTORM POTENTIAL.  
 
EXTENDED DISCUSSION...  
SHOWERS AND THUNDERSTORMS ARE EXPECTED TO INCREASE IN AREAL COVERAGE  
DURING THE DAY FRIDAY ALONG AND AHEAD OF A DRYLINE THAT WILL MOVE  
EAST ACROSS THE REGION THROUGHOUT THE DAY. THE PRIMARY SEVERE  
WEATHER THREATS WITH THESE STORMS WILL BE DAMAGING STRAIGHT LINE  
WINDS AND LOCALLY HEAVY RAINFALL, ESPECIALLY IN FAR EASTERN  
OKLAHOMA AND WESTERN ARKANSAS. ADDITIONAL STORMS MAY DEVELOP  
DURING THE OVERNIGHT HOURS FRIDAY AS THE UPPER LEVEL LOW MOVES  
OVERHEAD. STORMS ASSOCIATED WITH THE UPPER LOW WILL HAVE SOME  
POTENTIAL FOR QUARTER SIZE HAIL. THUNDERSTORM CHANCES WILL  
DECREASE FROM WEST TO EAST SATURDAY AS THE UPPER LOW CLEARS THE  
AREA.  
 
ADDITIONALLY, THERE IS POTENTIAL FOR A RAPID INCREASE IN FIRE  
DANGER FRIDAY AFTERNOON ACROSS NORTHEAST OKLAHOMA MAINLY WEST OF  
HIGHWAY 75 BEHIND THE DRYLINE. GUSTY, DRY SOUTHWEST WINDS OF 25 TO  
35 MILES AN HOUR DURING THE AFTERNOON WILL DROP RELATIVE HUMIDITY  
VALUES TO AROUND 25% IN THESE LOCATIONS DURING THE AFTERNOON.  
 
AN ACTIVE WEATHER PATTERN WILL RESUME LATE SUNDAY AND LIKELY  
WILL CONTINUE WELL INTO NEXT WEEK. THIS WILL RESULT IN MULTIPLE  
CHANCES FOR THUNDERSTORMS, ALONG WITH SOME SEVERE STORM  
POTENTIAL.
