DISCUSSION
(TONIGHT THROUGH NEXT TUESDAY)
ISSUED AT 1149 PM CDT TUE AUG 4 2026
CLEAR SKIES PREVAIL ACROSS THE MID-SOUTH AS A WEAKENING RIDGE
BUILDS IN FROM THE NORTHWEST. WHILE A CUTOFF LOW OVER NORTHEAST
GEORGIA KEEPS THE DEEP SOUTH SEASONABLY COOL, THE RIDGE HAS
ALLOWED TEMPERATURES TO REBOUND LOCALLY. DRY CONDITIONS WILL
PERSIST ACROSS THE MID-SOUTH THROUGH AT LEAST MIDWEEK.
HIGHS WILL CLIMB INTO THE LOW TO MID-90S AFTER WEDNESDAY AS
SOUTHERLY FLOW DEVELOPS IN RESPONSE TO THE WEAKENING CUTOFF LOW
AND DEEPENING LOW PRESSURE OVER THE SOUTHERN PLAINS. THIS FLOW
WILL PUSH DEW POINTS INTO THE UPPER 70S BY THURSDAY, DRIVING HEAT
INDICES INTO THE TRIPLE DIGITS. PORTIONS OF NORTHWEST MISSISSIPPI
AND EAST-CENTRAL ARKANSAS, PRIMARILY SOUTH OF MEMPHIS, MAY
APPROACH HEAT ADVISORY CRITERIA (105F) ON THURSDAY.
A WEAK TROUGH IN NORTHWEST FLOW WILL INCREASE RAIN AND
THUNDERSTORM CHANCES BY FRIDAY, THOUGH GUIDANCE LIMITS POPS TO
AROUND 30%, WITH THE HIGHEST COVERAGE NORTH OF I-40. WHILE THIS
SHORTWAVE AND ASSOCIATED CLOUD COVER MAY SLIGHTLY CURB SATURDAY'S
TEMPERATURES, ELEVATED HUMIDITY WILL MAINTAIN TRIPLE-DIGIT HEAT
INDICES ACROSS MUCH OF THE REGION.
AS THE TROUGH SHIFTS EAST, SUNDAY LOOKS SLIGHTLY DRIER AND A
DEGREE OR TWO WARMER, MAINLY DUE TO THE LACK OF CLOUDS AND
PRECIPITATION. THE THREAT OF HEAT ADVISORY CONDITIONS WILL
PERSIST INTO EARLY NEXT WEEK.
