DISCUSSION
(TONIGHT THROUGH NEXT MONDAY)
ISSUED AT 1132 PM CDT MON AUG 3 2026
A CUTOFF LOW OVER THE SOUTHEASTERN US HAS FINALLY SHIFTED FAR
ENOUGH EAST AS TO HAVE LOST ITS INFLUENCE ON THE MID-SOUTH. AS A
RESULT, WARMER TEMPERATURES AND CLEAR SKIES HAVE RETURNED TO THE
REGION.
A RIDGE WILL SHIFT OVER THE SOUTHERN PLAINS TODAY, SHUNTING THE
TROUGH EAST. AS THE RIDGE BUILDS IN FROM THE WEST, TEMPERATURES
WILL TREND CLOSER TO NORMAL TODAY. EXPECT HIGHS IN THE MIDDLE 80S
TO LOWER 90S. HEAT INDICES SHOULD REMAIN BELOW 100 DEGREES.
TOMORROW, THE RIDGE WILL DEAMPLIFY AND TRANSITION ACROSS THE
MISSISSIPPI RIVER VALLEY, INITIATING A WARMING TREND WITH LOW TO
MID-90S EXPECTED FROM THURSDAY THROUGH THE WEEKEND. THIS PATTERN
WILL SUPPRESS CONVECTION THROUGH THURSDAY, WITH ONLY MARGINAL
RAIN CHANCES (20-30%) RETURNING BY FRIDAY.
THE WEEKEND INTO EARLY NEXT LOOKS HOT AND HUMID, BUT NOTHING
UNSEASONABLY WARM. INCREASED CLOUD COVER FRIDAY THROUGH THE
WEEKEND MAY KEEP TEMPERATURES IN CHECK A BIT, BUT INCREASING
HUMIDITY WILL BOOST HEAT INDICES NONETHELESS. HEAT INDEX VALUES
HEAT ADVISORY CRITERIA OF 105F SHOULD BE MOSTLY CONFINED TO THE
MS DELTA REGION, SOUTH OF MEMPHIS. THERE IS UNCERTAINTY INTO HOW
BROAD OR DEEP THE TROUGH WILL EMERGE, WHICH WILL HEAVILY
INFLUENCE TEMPERATURES AND PRECIPITATION THIS WEEKEND. FOR NOW, A
20-40% POP WAS MAINTAINED THROUGH THE WEEKEND.
