THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...THIS EVENING AND TONIGHT.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...ELEVATED.
AREA...EASTERN OKLAHOMA AND NORTHWESTERN ARKANSAS.
ONSET...ONGOING.

DANGEROUS HEAT.
RISK...ELEVATED.
AREA...EASTERN OKLAHOMA AND NORTHWESTERN ARKANSAS.
ONSET...ONGOING.

DISCUSSION...
WIDELY SCATTERED THUNDERSTORMS HAVE DEVELOPED THIS AFTERNOON
ACROSS FAR EASTERN OKLAHOMA AND NORTHWESTERN ARKANSAS. THIS
ACTIVITY WILL CONTINUE THROUGH THIS EVENING AND THEN MUCH OF IT
WILL LIKELY DISSIPATE AFTER SUNSET. THE STRONGER STORMS WILL BE
CAPABLE OF PRODUCING WIND GUSTS TO 50 MPH. ADDITIONAL
THUNDERSTORM DEVELOPMENT IS EXPECTED ACROSS NORTHEASTERN OKLAHOMA
LATE TONIGHT AS A WEAK FRONT APPROACHES THE REGION FROM THE NORTH.

DANGEROUS HEAT INDICES IN THE 105 TO 110 DEGREE RANGE HAVE ONCE
AGAIN DEVELOPED ACROSS MUCH OF THE AREA THIS AFTERNOON. CONDITIONS
SHOULD IMPROVE AFTER SUNSET THIS EVENING. A HEAT ADVISORY REMAINS
IN EFFECT FOR THE ENTIRE AREA UNTIL 9 PM THIS EVENING.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
MONDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.
TUESDAY THROUGH SATURDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...
THE RIDGE OF HIGH PRESSURE ALOFT WILL GRADUALLY WEAKEN AND SHIFT
WEST THIS WEEK. A WEAK FRONTAL BOUNDARY WILL APPROACH THE AREA ON
MONDAY...SUPPORTING A CHANCE OF THUNDERSTORMS INTO MID WEEK AS THE
BOUNDARY BECOMES DIFFUSE OVER THE REGION. A MOIST AND UNSTABLE AIR
MASS WILL PERSIST OVER THE REGION INTO NEXT WEEKEND...RESULTING IN
DAILY THUNDERSTORM CHANCES.

DANGEROUS AFTERNOON HEAT INDICES TO AROUND 105 DEGREES ARE AGAIN
FORECASTED ON MONDAY ACROSS NORTHEAST OKLAHOMA. AN INCREASE IN
CLOUDS AND THE WEAKENING MID LEVEL HIGH PRESSURE RIDGE WILL RESULT
IN LESS HEAT IMPACTS FOR THE REMAINDER OF THE WEEK...DESPITE
TEMPERATURES BEING NEAR SEASONAL AVERAGES.
