DISCUSSION...  
WIND GUSTS HAVE COME VERY CLOSE TO HIGH WIND CRITERIA THIS  
AFTERNOON NEAR SPS WHERE MIXING HAS RESULTED IN BETTER MOMENTUM  
TRANSFER. IN ADDITION, WIDELY SCATTERED COLD CORE SHOWERS ARE  
ROTATING AROUND THE LOW ACROSS CENTRAL AND NORTHERN OK. THESE  
SHOWERS WILL LIKELY END BEFORE OR NEAR SUNSET THIS EVENING AS THE  
LOW LIFTS NE. WIND SPEEDS WILL ALSO DECREASE WITH DECOUPLING,  
ALTHOUGH THE PRESSURE GRADIENT WILL CONTINUE TO RESULT IN BREEZY  
CONDITIONS THRU MOST OF THE EVENING.  
 
MONDAY LOOKS BEAUTIFUL. SKIES WILL REMAIN CLEAR AND WIND SPEEDS  
WILL DECREASE TO AROUND 10 TO 15 MPH. HIGHS WILL CLIMB INTO THE  
LOW 70S FOR MOST LOCATIONS. BY TUE, EAST TO SOUTHEAST WINDS WILL  
RETURN AS SFC LOW DEVELOPS AHEAD OF A MID TO UPPER SHORTWAVE  
TROUGH MOVING OUT OF THE ROCKIES. A WARM FRONT WILL LIFT NORTHWARD  
TO NEAR THE I40 CORRIDOR DURING THE EVENING HOURS, WHILE MID LEVEL  
ASCENT INCREASES WITH WAA OVER THE NORTHERN/NE HALF OF OK. THERE  
MAY BE ENOUGH ELEVATED INSTABILITY TO PRODUCE SOME STRONGER STORMS  
WITH SMALL HAIL. A COLD FRONT WILL THEN MOVE THROUGH MOST OF OK  
DURING THE DAY WED, WITH THE SFC LOW SOMEWHERE NEAR THE RED RIVER  
OVER SE OK. ADDITIONAL MOIST CONVECTION WILL BE POSSIBLE OVER THIS  
REGION DURING THE AFTERNOON. RAIN CHANCES SHOULD END FOR THE  
ENTIRE AREA AFTER SUNSET WED.  
 
AFTER A BRIEF COOLDOWN BEHIND THE FRONT WED AND THU, TEMPS WILL  
CLIMB BACK TO NEAR AVERAGE BY NEXT WEEKEND AS AN UPPER LEVEL RIDGE  
SETS UP OVER THE CENTRAL CONUS. THIS WARMING TREND WILL LIKELY  
CONTINUE INTO AT LEAST EARLY NEXT WEEK.
