DISCUSSION
ISSUED AT 228 AM CDT FRI AUG 21 2026
CURRENTLY, AS OF 2 AM CDT, A STATIONARY BOUNDARY REMAINS DRAPED
ALONG THE I-40 CORRIDOR ACROSS CENTRAL ARKANSAS. THIS BOUNDARY IS
EXPECTED TO GRADUALLY TRACK SOUTHWARD AS A WEAK COLD FRONT INTO
SOUTHERN ARKANSAS TODAY.
IN RESPONSE, HIGH TEMPERATURES ACROSS MUCH OF THE STATE WILL
EXPERIENCE A VERY LIMITED FORM OF RELIEF. INSTEAD OF WIDESPREAD 100F
TO 105F OR GREATER TEMPERATURES ACROSS A LARGE PART OF THE STATE,
MANY LOCATIONS ACROSS ARKANSAS MAY ONLY REACH THE UPPER 90S,
POSSIBLY ENDING SEVERAL STREAKS STATEWIDE OF MULTIPLE 100 DEGREE OR
HIGHER DAYS ON FRIDAY.
THIS TREND IS EXPECTED TO CONTINUE OVER THE NEXT SEVERAL DAYS AS
HIGH TEMPERATURES WILL STILL PEAK WELL ABOVE NORMAL FOR THIS TIME OF
THE YEAR ACROSS MOST OF THE STATE, BUT MAY STRUGGLE TO REACH 100
DEGREES IN MANY LOCATIONS.
THE TREND IS THE RESULT OF NORTHWESTERLY FLOW ALOFT OVER ARKANSAS AS
THE UPPER LVL RIDGE IS EXPECTED TO REMAIN CEMENTED OVER THE FOUR
CORNERS REGION OF THE CONUS. IN RESPONSE, A SERIES OF FRONTAL
BOUNDARIES ARE EXPECTED TO MOVE THROUGH THE STATE WHICH WILL
INTRODUCE LIMITED INCREASES IN CHANCES FOR POPS, INCREASED CLOUD
COVER, AND A SLIGHT REDUCTION IN TEMPERATURES OVERALL.
A CONTINUED PATTERN OF HOT AND DRY CONDITIONS ARE EXPECTED TO
CONTINUE OVERALL ACROSS THE STATE, BUT OPPRESSIVE TEMPERATURES, IN
THE THE FORM OF EXTREME HIGH AIR TEMPERATURES ARE NOT EXPECTED TO BE
NEAR THE VALUES EXPERIENCE OVER THE LAST SEVERAL DAYS.
UNFORTUNATELY, HEAT INDEX VALUES WILL REMAIN BETWEEN 105 AND 109
DEGREES ACROSS MOST OF CENTRAL AND SOUTHERN ARKANSAS PROMPTING THE
CONTINUATION OF THE HEAT ADVISORY FOR TODAY.
