WITH THE STRONGEST STORMS AS THEY POTENTIALLY TRACK ACROSS
NORTHEAST OKLAHOMA AND INTO NORTHWEST ARKANSAS.
OTHERWISE, HOT AND HUMID CONDITIONS WILL BUILD BACK INTO THE
REGION THIS AFTERNOON, PARTICULARLY SOUTH OF THE WEAK BOUNDARY.

LIKELY MOST DAYS ACROSS THE AREA. A POTENTIAL STRONGER COLD FRONT
COULD ARRIVE TOWARD THE END OF NEXT WEEK, BRINGING INCREASING
THUNDERSTORM CHANCES AND COOLER TEMPERATURES.
