 AREA...EASTERN OKLAHOMA AND WEST CENTRAL ARKANSAS.
 ONSET...THIS AFTERNOON.

DISCUSSION...

ISOLATED THUNDERSTORMS ARE POSSIBLE OVER MAINLY THE ELEVATED
TERRAIN AREAS OF SOUTHEAST OKLAHOMA THIS AFTERNOON. LIGHTNING
WOULD BE THE MAIN THREAT, AND ANY ACTIVITY THAT DEVELOPS WOULD
DISSIPATE BY SUNSET THIS EVENING.

UNSEASONABLE HEAT AND HUMIDITY IS EXPECTED TODAY WITH AFTERNOON
HEAT INDICES EXPECTED TO TOP OUT IN THE 100 TO 105 DEGREE RANGE.
CONDITIONS WILL IMPROVE BY SUNSET THIS EVENING.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION NOT EXPECTED.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY THRU FRIDAY...NO HAZARDS.
SATURDAY AND SUNDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...

A RIDGE OF HIGH PRESSURE ALOFT WILL BUILD OVER THE REGION THIS
WEEK, BRINGING MUCH ABOVE AVERAGE WARMTH AND DRY WEATHER. THE HEAT
COMBINED WITH HIGHER HUMIDITY EARLY THIS WEEK WILL PUSH AFTERNOON
HEAT INDICES INTO THE 100 TO 105 DEGREE RANGE AGAIN ON TUESDAY.
HEAT INDICES SHOULD FALL BACK A BIT LATER THIS WEEK AS THE AIR
DRIES OUT SOME.

A COLD FRONT WILL BRING THE NEXT CHANCE FOR THUNDERSTORMS NEXT
WEEKEND.
