DANGEROUS HEAT.
RISK...ELEVATED.

DISCUSSION...
ABNORMALLY HIGH HUMIDITY COMBINED WITH TEMPERATURES IN THE LOW TO MID
90S ACROSS EASTERN OKLAHOMA HAS RESULTED IN HEAT INDEX VALUES FROM
105 TO 110 DEGREES THIS AFTERNOON. THESE CONDITIONS WILL CONTINUE
INTO THIS EVENING BUT WILL IMPROVE AS SUNSET APPROACHES AND
TEMPERATURES BEGIN TO FALL.

ISOLATED TO WIDELY SCATTERED THUNDERSTORMS ARE POSSIBLE ACROSS
SOUTHEASTERN OKLAHOMA AND NORTHWESTERN ARKANSAS THIS EVENING. ANY OF
THIS ACTIVITY THAT DOES FORM WILL STRUGGLE TO PERSIST PAST SUNSET.
SEVERE WEATHER CHANCES ARE LOW WITH ANY ACTIVITY THAT FORMS BUT NOT
ZERO DUE TO A HIGHLY UNSTABLE ATMOSPHERE...WHICH WOULD SUPPORT LARGE
HAIL AND DAMAGING WIND GUSTS.

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

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY THROUGH WEDNESDAY...DANGEROUS HEAT POTENTIAL.

EXTENDED DISCUSSION...
AN EXTENDED PERIOD OF HOT AND HUMID WEATHER IS EXPECTED FRIDAY...
THROUGH THE WEEKEND...AND WELL INTO NEXT WEEK AS AN UPPER LEVEL
RIDGE BUILDS ACROSS THE REGION.

AFTERNOON HEAT INDEX VALUES BETWEEN 105 AND 113 DEGREES APPEAR
LIKELY DURING THIS PERIOD.
