DISCUSSION
(TODAY THROUGH TUESDAY)
ISSUED AT 1200 AM CDT WED JUN 24 2026
STATIONARY FRONT LOOMS OVER SOUTHERN ARKANSAS TODAY WHILE DRY, HIGH
PRESSURE SITS OVER THE CENTRAL GULF WATERS. THE ORIENTATIONS AND
MEAN UPPER LEVEL FLOW WILL CONTINUE TO DIVERT CONVECTIVE SHOWER AND
STORMS TO THE NORTH AND EAST OF THE FORECAST AREA.
LOCALLY, THIS PATTERN RESULTS IN ANOTHER SEASONABLY HOT AFTERNOON
WHERE LIGHT SOUTH WINDS AND TEMPERATURES REACHING THE LOW 90S CAN BE
EXPECTED. BROAD HIGH PRESSURE IS EXPECTED TO REMAIN INTACT THROUGH
THURSDAY AS THE TROUGH PATTERN TO OUR NORTH MIGRATES OVER THE
CAROLINAS. NO MAJOR CHANGES IN THE FORECAST THROUGH THE REST OF THE
WORK WEEK AT THIS TIME. THE UPPER AIR PATTERN IS FORECAST TO BE
RELATIVELY QUIET WITH PLENTY OF MID LEVEL SUBSIDENCE WARMING TO
INHIBIT CONVECTION. HIGHS WILL CONTINUE TO RANGE IN THE LOW OR MID
90S. DESPITE THE AMOUNT OF SOIL MOISTURE FROM RECENT RAINFALLS, 7-12
MPH SURFACE WINDS, HAVE BEEN ABLE TO HELP MIX THIS HUMID AIR INTO
THE LOWER TROPOSPHERE. WHILE THAT EFFECT HAS HELPED LOWERED MANY
INTERIOR CITIES BELOW HEAT ADVISORY CRITERIA, REST, TIME TO COOL
OFF, AND PLENTY OF HYDRATION ARE ALL ENCOURAGED IN THIS SUMMERTIME
PATTERN.
BY THE WEEKEND, HIGH PRESSURE RIDGING OVER THE WESTERN ATLANTIC
BEGINS TO ELONGATE WESTWARD OVER THE FLORIDA PENINSULA. STILL
EXPECTING A DRY WEEKEND, HOWEVER, WINDS WILL BEGIN TO ACQUIRE MORE
SOUTHEASTERLY COMPONENTS. HIGHS WILL REMAIN IN THE LOW TO MID 90S
AREAWIDE. HOWEVER, GUIDANCE DOES SHOW THE COLUMN BEGIN TO MOISTEN
IN THE LOWER TROPOSPHERE SUNDAY. AT MOST THIS ORIENTATION OF THE
UPPER LEVEL FLOW MIGHT ALLOW FOR DIURNALLY DRIVEN POP UP SHOWER
ACTIVITY TO REENTER THE FORECAST EARLY NEXT WEEK.

WILL BE LOW FOR THE NEXT SEVEN DAYS AND 1 TO 10 HOUR FUELS WILL
BEGIN TO DRY OUT. OVERALL THE FIRE WEATHER CONCERNS WILL REMAIN LOW.
