DISCUSSION
ISSUED AT 242 AM CDT SAT AUG 22 2026
THE CONTINUED TREND OF NORTHWESTERLY FLOW ALOFT OVER ARKANSAS WILL
REMAIN. AN UPPER LVL SHORTWAVE PROGGED TO MOVE OVER THE STATE WILL
ALLOW A WEAK FRONT TO DROP DOWN INTO ARKANSAS BY EARLY AFTERNOON AND
TRACK SOUTHWARD ACROSS THE STATE. THE AIRMASS AHEAD OF THIS
ADVANCING WEAK COLD FRONT WILL BE HOT AND HUMID WITH PLENTY OF CAPE
ALLOWING FOR THE EXPECTED DEVELOPMENT OF SCATTERED THUNDERSTORMS
ACROSS THE STATE BETWEEN EARLY THIS AFTERNOON INTO LATE THIS
EVENING.
THE STORM PREDICTION CENTER HAS DESIGNATED THE ENTIRE STATE OF
ARKANSAS IN A MARGINAL RISK (LEVEL 1 OF 5) FOR SEVERE WEATHER TODAY
WITH THE MAIN HAZARDS POSSIBLE AS DAMAGING WIND GUSTS AND A FEW
INSTANCES OF LARGE HAIL WITH ANY STORM THAT DOES MANAGE TO BECOME
SEVERE.
BEFORE THE ANTICIPATED ARRIVAL OF THE WEAK COLD FRONT AND ASSOCIATED
SCATTERED CONVECTION, HIGH TEMPERATURES ARE EXPECTED TO REACH OR
EXCEED 100 DEGREES ACROSS MOST OF CENTRAL AND SOUTHERN ARKANSAS. A
CHALLENGING HIGH TEMPERATURE FORECAST FOR TODAY AS LOCATIONS ACROSS
THE STATE, ESPECIALLY IN CENTRAL AND SOUTHERN ARKANSAS WILL LIKELY
EXPERIENCE COMPRESSION HEATING JUST AHEAD OF THE ADVANCING FRONT
WHERE TEMPERATURES WILL QUICKLY, BUT BRIEFLY RISE A FEW DEGREES
BEFORE THE FRONTAL BOUNDARY OVERTAKES A LOCATION. FOR THIS REASON
AND OVERALL TRENDS DURING THIS HEATWAVE HAVE TRENDED TOWARD NBM 75%
AND NBM 90% VALUES.
FOR THE REMAINDER OF THE FORECAST PERIOD, FROM SUNDAY THROUGH THE
UPCOMING WORKWEEK, EXPECT HOT TEMPERATURES TO PERSIST WITH A FEW
DAYS OF RELIEF POSSIBLE WHICH WOULD LOWER TEMPERATURES A TAD TO
NORMAL VALUES FOR THIS TIME OF THE YEAR AS MULTIPLE WEAK FRONTAL
BOUNDARIES ARE ANTICIPATED TO MOVE ACROSS THE STATE WHICH WILL
PROMOTE APPRECIABLE POP CHANCES (EXPECTED ON MONDAY) AND MODEST POP
CHANCES (ON WEDNESDAY INTO WEDNESDAY NIGHT).
