THE 12Z AVIATION DISCUSSION FOLLOWS....  
 

 
   
AVIATION
 
 
AN AREA OF VERY LOW CEILINGS AND FOG OVER SOUTHEAST OKLAHOMA WILL  
NOT AFFECT ANY OF OUR TAF SITES, AND SHOULD DISSIPATE TOWARD MID-  
MORNING. SIMILARLY, ISOLATED LIGHT SHOWERS OVER THE NORTHWEST  
QUARTER OF OKLAHOMA SHOULD DIMINISH GRADUALLY THROUGH ABOUT 18Z,  
WITH LITTLE TO NO EFFECT ON AVIATION.  
 
WINDS WILL BE SOMEWHAT ERRATIC TODAY, AS A WEAK SURFACE FRONT  
DRIFTS ACROSS THE SOUTHEAST HALF OF OKLAHOMA. WINDS SHOULD GO BACK  
TO LIGHT AND VARIABLE TONIGHT AT MOST SITES.  
 
THERE IS A CHANCE THAT HIGH PLAINS THUNDERSTORMS WILL REACH  
WESTERN OKLAHOMA EARLY FRIDAY MORNING. CHANCES ARE CURRENTLY TOO  
LOW TO INCLUDE IN TAFS.

DISCUSSION...  
FOG HAS FORMED OVER PARTS OF SOUTHEAST OKLAHOMA EARLY THIS  
MORNING. WITH NEARLY CALM WINDS, CLEAR SKIES, AND RELATIVE  
HUMIDITIES AROUND 100%, THIS FOG ISN'T LIKELY TO DISSIPATE UNTIL  
MID-MORNING. IN ADDITION, LIGHT RAIN IS INDICATED BY KVNX RADAR  
ACROSS SOUTHWEST KANSAS AND FAR NORTHWEST OKLAHOMA, DRIFTING  
SOUTHEAST. THESE ISOLATED LIGHT SHOWERS WILL PROBABLY LAST INTO  
LATE MORNING, BUT RAINFALL WILL BE MINIMAL.  
 
WHILE THERE WILL BE A CHANCE OF SHOWERS/THUNDERSTORMS TONIGHT AND  
TOMORROW, THE NEXT REALLY BIG CHANCE WILL BE FRIDAY EVENING AND  
NIGHT, AS ANOTHER STORM COMPLEX IS EXPECTED TO FORM, AND MOVE  
GENERALLY EAST ACROSS OUR FORECAST AREA. THEN, SATURDAY WILL HAVE  
A SIMILAR SETUP AS YESTERDAY (WEDNESDAY). THERE ARE RISKS OF  
SEVERE STORMS WITH BOTH THE FRIDAY NIGHT MCS AND THE SATURDAY  
STORMS.  
 
AS SURFACE BOUNDARIES REMAIN OVER OKLAHOMA AND PERHAPS NORTH  
TEXAS, AND VARIOUS WAVES MOVE THROUGH THE GENERALLY WEST-NORTHWEST  
FLOW ALOFT, THERE WILL BE PERIODIC CHANCES OF RAIN/STORMS INTO  
EARLY NEXT WEEK. FORECAST CONFIDENCE DROPS OF QUICKLY TOWARD THE  
MIDDLE OF NEXT WEEK AS MODEL DIFFERENCES BECOME GREATER.  
 
IT STILL LOOKS QUITE HOT IN OUR TEXAS COUNTIES AND SURROUNDING  
OKLAHOMA COUNTIES THIS WEEKEND. WICHITA FALLS WILL BE CLOSE TO A  
RECORD HIGH ON SATURDAY.
