DISCUSSION
 
 
AN UPPER-LEVEL SHORTWAVE TROUGH OVER THE WESTERN UNITED STATES  
WILL ADVANCE SLOWLY EAST TODAY, AS LOW-LEVEL MOISTURE IS DRAWN  
BACK NORTH INTO OKLAHOMA AND NORTH TEXAS. ELEVATED WARM-AIR  
ADVECTION IN ADVANCE OF THE TROUGH WILL LIKELY SET OFF A FEW  
SHOWERS AND THUNDERSTORMS THIS MORNING OVER WESTERN OKLAHOMA AND  
ADJACENT PARTS OF TEXAS. WHILE THERE IS A POSSIBILITY THAT SOME  
OF THESE STORMS MAY BE SEVERE, THE MAIN RISK OF SEVERE STORMS WILL  
COME THIS AFTERNOON, EVENING, AND INTO THE OVERNIGHT HOURS.  
SHORT-RANGE MODELS SUGGEST THAT SUPERCELL STORMS THAT FORM THIS  
AFTERNOON OVER SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS WILL  
MERGE INTO A LINE OF STORMS, AND THIS LINE WILL THEN MOVE EAST  
ACROSS CENTRAL AND EASTERN OKLAHOMA LATE THIS EVENING AND  
OVERNIGHT.  
 
THE UPPER-LEVEL WAVE WILL DEPART TO THE EAST TOMORROW/TOMORROW  
NIGHT, BUT NOT BEFORE SUPPORTING ANOTHER HIGH CHANCE OF  
THUNDERSTORMS OVER MUCH OF OKLAHOMA AND POSSIBLY NORTH TEXAS. A  
FEW OF THESE STORMS MAY BE SEVERE OVER THE EASTERN HALF OR SO OF  
OKLAHOMA.  
 
RAIN CHANCES FINALLY END THURSDAY EVENING, ONLY TO RETURN AGAIN  
FRIDAY EVENING, AS ANOTHER STORM SYSTEM ADVANCES TOWARD THE  
SOUTHERN PLAINS. AGAIN, A FEW SEVERE STORMS WILL BE POSSIBLE ON  
SATURDAY.  
 
FOR THIS MORNING, SOME FOG IS LIKELY ACROSS PARTS OF OKLAHOMA,  
MAINLY NEAR A LINE FROM WOODWARD TO OKLAHOMA CITY, BUT THE FOG  
SHOULD NOT LAST MORE THAN A FEW HOURS, AND ONLY ISOLATED AREAS OF  
DENSE FOG ARE EXPECTED.
