DISCUSSION
ISSUED AT 123 PM CDT TUE JUN 9 2026
TONIGHT THROUGH WEDNESDAY NIGHT...
QUIET CONDITIONS WILL PREVAIL ACROSS OUR CWA TONIGHT THANKS TO THE
SUBTROPICAL RIDGE OVER THE SOUTHEAST CONUS. SKY COVER HEADING INTO
THE OVERNIGHT PERIOD WILL BE GENERALLY CLEAR. THIS COMBINED WITH
CALM SOUTHERLY WINDS WILL ALLOW FOR RADIATIONAL COOLING TO OCCUR
AREAWIDE. THIS WILL ALLOW FOR NIGHTTIME LOWS TO DIP INTO THE LOW/MID
70S. SIMILAR CONDITIONS ARE EXPECTED TOMORROW ON WEDNESDAY WITH
DAYTIME HIGHS PEAK INTO THE LOW/MID 90S. HEAT INDICES WILL BE ON THE
RISE WEDNESDAY WITH HEAT INDEX VALUES REACHING THE TRIPLE DIGITS
MAINLY FOR AREAS ALONG AND WEST OF I-55 AND DOWN TOWARDS THE PINE
BELT. AREAS EAST OF I-55 WILL SEE HEAT INDEX VALUES IN THE UPPER
90S. CLEAR AND QUIET CONDITIONS WILL PREVAIL ACROSS OUR CWA
WEDNESDAY NIGHT WITH LOWS IN THE LOW/MID 70S.
THURSDAY THROUGH NEXT TUESDAY...
ANOTHER ROUND OF QUIET WEATHER IS IN THE FORECAST AS WE HEAD INTO
THURSDAY. RAIN CHANCES WILL START TO INCREASE HEADING INTO FRIDAY AS
A COLD FRONT OVER THE CENTRAL PLAINS IS FORECASTED TO PUSH SOUTHEAST
TOWARDS THE LOWER MISSISSIPPI RIVER VALLEY. DESPITE THE SOMEWHAT
DECENT RAIN CHANCES (POPS AROUND 20%-40%) ON FRIDAY, FOLLOWED BY
LOWER CHANCES OF RAIN HEADING INTO THE WEEKEND, DANGEROUS HEAT IS
STILL THE PRIMARY FOCUS FOR THE LONG TERM PERIOD. THERE IS HIGHER
CONFIDENCE IN FRIDAY-SUNDAY BEING THE BEST DAYS FOR HEAT STRESS TO
PEAK AT 105 F DEGREES. AFTERNOON GUIDANCE CONTINUE TO HIGHLIGHT PEAK
HEAT RISK DURING THE FRIDAY-SUNDAY TIMEFRAME WHEN HIGHS ARE EXPECTED
TO REACH THE LOW/MID 90S AREAWIDE. WE WILL HOLD OFF ON MESSAGING FOR
DANGEROUS HEAT IN OUR HWO GRAPHICS FOR RIGHT NOW BUT WILL CONTINUE
TO HIGHLIGHT A MORE GENERAL HEAT THREAT UNTIL WE GET CLOSER TO
FRIDAY.
LOOKING AHEAD INTO EARLY NEXT WEEK, ANOTHER COLD FRONT WILL TRACK
SOUTH TOWARDS THE SOUTHEAST CONUS. THIS COMBINED WITH INCREASED FLOW
FROM THE SOUTH WILL HELP INCREASE MOISTURE AND RAIN CHANCES
ACROSS OUR CWA AS WE GO THROUGH THE NEXT SEVERAL DAYS. /CR/
