EXTENDED DISCUSSION...
THE UNSEASONABLY HOT AND HUMID WEATHER WILL PERSIST FOR MUCH OF

AREA. HEAT INDICES EACH AFTERNOON WILL RANGE FROM 95 TO 103
DEGREES ACROSS MUCH OF EASTERN OKLAHOMA AND WEST CENTRAL
ARKANSAS.
THUNDERSTORM CHANCES RETURN THURSDAY AND CONTINUE THROUGH THE
WEEKEND AS THE REMNANT TROPICAL MOISTURE FROM A POTENTIAL GULF
TROPICAL SYSTEM LIFTS NORTHWARD INTO THE AREA. SOME INTERACTION
WITH AN APPROACHING FRONT IS POSSIBLE BY LATE IN THE WEEKEND,
WHICH COULD FOCUS HEAVY RAIN POTENTIAL ACROSS NORTHEAST OKLAHOMA
AND NORTHWEST ARKANSAS.
