THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.
DAY ONE
THIS AFTERNOON AND TONIGHT.
THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...LIMITED.
AREA...CARROLL COUNTY ARKANSAS.
ONSET...AFTER 10 PM.
DANGEROUS HEAT.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA AND WEST-CENTRAL ARKANSAS.
ONSET...ONGOING.
DISCUSSION...
HIGH PRESSURE ALOFT WILL EXPAND EAST OVER THE REGION
DURING THE NEXT 24 HOURS. THIS WILL STABILIZE
THE ATMOSPHERE SOME. AN ISOLATED SHOWER COULD DEVELOP
IN THE HOT AND HUMID AIR...BUT THE DECREASE
IN INSTABILITY IS EXPECTED TO PREVENT THUNDERSTORM
DEVELOPMENT TODAY. A THUNDERSTORM COMPLEX IS FORECAST
TO MOVE ACROSS MISSOURI TONIGHT AND THERE IS A SLIGHT
CHANCE THAT IT COULD BRUSH CARROLL COUNTY LATE THIS EVENING
OR OVER NIGHT.
HEAT INDEX VALUES THIS AFTERNOON ARE EXPECTED TO TOP OUT BETWEEN
97 AND 102 ACROSS EASTERN OKLAHOMA AND WEST-CENTRAL ARKANSAS.
THESE READINGS ARE JUST BELOW ADVISORY CRITERIA...BUT
CARE SHOULD STILL BE TAKEN BY ANYONE THAT IS ACTIVE
OUTDOORS DURING THE HEAT OF THE DAY.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER ACTIVATION NOT EXPECTED.
DAYS TWO THROUGH SEVEN
FRIDAY THROUGH WEDNESDAY.
FRIDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.
SATURDAY...THUNDERSTORM POTENTIAL...DANGEROUS HEAT POTENTIAL.
SUNDAY...DANGEROUS HEAT POTENTIAL.
MONDAY...DANGEROUS HEAT POTENTIAL.
TUESDAY...DANGEROUS HEAT POTENTIAL.
WEDNESDAY...THUNDERSTORM POTENTIAL.
EXTENDED DISCUSSION...
SOME INCREASE IN LOW-LEVEL MOISTURE IS EXPECTED ON FRIDAY AND
SATURDAY AND THIS COULD LEAD TO A FEW THUNDERSTORMS DEVELOPING
IN THE AFTERNOON AND EVENING ON THESE DAYS. IN ADDITION...
A STORM COMPLEX FROM THE NORTHWEST COULD AFFECT PARTS OF THE
AREA LATE FRIDAY NIGHT AND SATURDAY MORNING.
ALSO OVER THE WEEKEND THE HEAT INDEX IS EXPECTED TO RISE
WITH VALUES AT OR ABOVE 100 ACROSS MUCH OF THE AREA.
PEAK READINGS NEAR 110 ARE POSSIBLE IN NORTHEAST OKLAHOMA
AND IN THE ARKANSAS RIVER VALLEY OF WEST-CENTRAL
ARKANSAS.
HIGH HEAT INDEX VALUES WILL CONTINUE INTO THE FIRST OF NEXT
WEEK...WITH AN INCREASE IN THUNDERSTORM POTENTIAL BY MID WEEK
AS AN UPPER-LEVEL DISTURBANCE FORCES A WEAK FRONT INTO THE
AREA.
EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY OFFICIALS WORKING OUTDOOR EVENTS IN THE COMING
DAYS SHOULD CONSIDER THE LIKELIHOOD THAT A NUMBER OF
EVENT PARTICIPANTS COULD BE AFFECTED BY THE HEAT AND
REQUIRE ATTENTION. A HEAT ADVISORY WILL LIKELY BE
RE-ISSUED FOR MUCH OF THE AREA.
