DISCUSSION
ISSUED AT 124 PM CDT SUN JUN 7 2026
TONIGHT THROUGH SATURDAY...SCATTERED TO WIDESPREAD SHOWERS, ALONG
WITH SOME THUNDERSTORMS, WILL REMAIN LIKELY ACROSS THE FORECAST AREA
INTO THIS EVENING. WHILE THERE WILL BE SOME LESSENING IN COVERAGE
OVERNIGHT, SOME ISOLATED TO SCATTERED CONVECTION WILL REMAIN
POSSIBLE ACROSS MAINLY NORTHERN PORTIONS OF THE AREA INTO EARLY
MONDAY MORNING, AS A SHORTWAVE LIFTS NORTHEAST THROUGH THE MID-SOUTH
REGION. SOME HEAVY DOWNPOURS WILL REMAIN POSSIBLE FOR THE REMAINDER
OF THIS AFTERNOON INTO THIS EVENING. THIS WILL RESULT IN THE
PONDING OF WATER IN LOW-LYING AND POOR DRAINAGE AREAS, ESPECIALLY
WHERE CONVECTION TRAINS ACROSS THE SAME LOCATIONS.
THIS DEEPLY MOIST AIRMASS WILL PERSIST ACROSS THE REGION DURING THE
WEEK. THE BULK OF THE RAIN CHANCES WILL EXIT THE CWA WITH THE
AFOREMENTIONED SHORTWAVE, WITH RIDGING INCREASING ACROSS THE REGION.
HOWEVER, GIVEN THE AIRMASS NOW RESIDING OVER THE FORECAST AREA, AN
ISOLATED DIURNALLY DRIVEN SHOWER OR STORM WILL REMAIN POSSIBLE EACH
AFTERNOON. IT'LL ALSO BE DURING THIS TIME WHERE THE CONCERN FOR
DANGEROUS HEAT STRESS WILL BE ON THE RISE. BY THE TIME TUESDAY ROLLS
AROUND, AND CONTINUING THROUGH SATURDAY, WITH HIGHS WARMING INTO THE
90S AND DEW POINTS WELL INTO THE 70S, AFTERNOON HEAT INDEX VALUES
CURRENTLY LOOK TO REACH AND EVENTUALLY SURPASS THE CENTURY MARK. IF
THE TREND CONTINUES, AT A MINIMUM, A "LIMITED THREAT" FOR SAID
DANGEROUS HEAT STRESS COULD BECOME NECESSARY AS EARLY AS WEDNESDAY
FOR PORTIONS OF, IF NOT ALL OF, THE FORECAST AREA, AND POTENTIALLY
BE NEEDED FOR CONSECUTIVE DAYS HEADING INTO THE WEEKEND. /19/
