DISCUSSION
ISSUED AT 124 PM CDT SAT JUN 6 2026
TONIGHT THROUGH NEXT FRIDAY...SHOWERS, ALONG WITH A FEW STORMS,
THIS WEEKEND AND THE POTENTIAL FOR INCREASED HEAT STRESS DURING
THE UPCOMING WEEK REMAIN THE WEATHER STORIES DURING THIS FORECAST
PERIOD. DEEP MOISTURE CONTINUES TO INCREASE ACROSS THE REGION AS A
SHORTWAVE GRADUALLY MOVES INTO AND THROUGH THE FORECAST AREA
THROUGH MONDAY. THIS WILL KEEP GOOD RAIN CHANCES IN THE FORECAST
FOR THE REMAINDER OF THIS AFTERNOON AND AGAIN ON SUNDAY. THERE
WILL BE SOME LULL IN ACTIVITY BOTH TONIGHT AND SUNDAY NIGHT, BUT
GIVEN THE MOISTURE-RICH ENVIRONMENT OVER THE REGION SOME SHOWERS
WILL REMAIN POSSIBLE DURING THE OVERNIGHT HOURS. WHILE FLASH
FLOODING IS NOT EXPECTED, RAINFALL COULD BE HEAVY AT TIMES GIVEN
THE COPIOUS AMOUNT OF MOISTURE OVERSPREADING THE REGION THIS
WEEKEND. THIS COULD HOWEVER RESULT IN THE PONDING OF WATER IN BOTH
LOW-LYING AND POOR DRAINAGE AREAS.
THE DEEPLY MOIST AIRMASS WILL PERSIST ACROSS THE REGION DURING THE
UPCOMING WORK WEEK. THE BULK OF THE RAIN CHANCES WILL EXIT THE CWA
WITH THE AFOREMENTIONED SHORTWAVE, WITH RIDGING INCREASING ACROSS
THE REGION. BUT GIVEN THE AIRMASS OVER THE FORECAST AREA, SOME
ISOLATED TO SCATTERED DIURNALLY DRIVEN CONVECTION WILL REMAIN
POSSIBLE DURING THE WEEK. 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 FRIDAY, WITH HIGHS IN
THE 90S AND DEW POINTS WELL INTO THE 70S, AFTERNOON HEAT INDEX
VALUES CURRENTLY LOOK TO REACH AND EVENTUALLY SURPASS THE CENTURY
MARK. WHILE THIS IS STILL SEVERAL DAYS OUT, IF THE TREND CONTINUES,
AT A MINIMUM, A "LIMITED THREAT" FOR SAID DANGEROUS HEAT STRESS WILL
NEED TO BE ADDED TO THE HWO FOR PORTIONS OF, IF NOT ALL OF, THE
FORECAST AREA FOR THE MIDDLE AND LATTER PORTION OF NEXT WEEK. /19/
