DISCUSSION
ISSUED AT 234 AM CDT SUN AUG 2 2026
TODAY THROUGH SATURDAY...INCREASED TROUGHING ACROSS THE EASTERN HALF
OF THE UNITED STATES, HAS FORCED A FRONTAL BOUNDARY SOUTH AND
THROUGH THE FORECAST AREA. IN THE BOUNDARY'S WAKE, SLIGHTLY DRIER
AIR HAS BEGUN FILTERING SOUTH INTO THE REGION. THIS DRIER AIR,
ALONG WITH SOME CLOUD COVER TODAY ACROSS THE NORTH, WILL PROVIDE
SOME TEMPORARY RELIEF FROM THE OPPRESSIVE HEAT THAT'S GRIPPED THE
REGION FOR SOME TIME. AS DEW POINTS BOTH TODAY AND MONDAY MIX INTO
THE MID 60S AND LOWER 70S, HIGHS TODAY WILL RANGE FROM THE MIDDLE
80S TO LOWER 90S AND FROM THE UPPER 80S TO MIDDLE 90S COME MONDAY.
UNFORTUNATELY, THIS'LL ALL BE SHORT-LIVED AS WE MOVE INTO THE MID
AND LATTER PORTIONS OF THE FORECAST PERIOD. STRONG HIGH PRESSURE
ALOFT WILL RE-ASSERT ITSELF ACROSS THE LOWER MISSISSIPPI RIVER
VALLEY DURING THIS TIME. HIGH TEMPERATURES WILL AGAIN BEGIN
CLIMBING BACK INTO THE MID AND UPPER 90S AREAWIDE. MOISTURE LEVELS
WILL ALSO BEGIN CREEPING UP MID AND LATE WEEK. THIS CURRENTLY LOOKS
TO AGAIN LEAD TO A BOUT OF DANGEROUS HEAT STRESS CONDITIONS ACROSS
MOST, IF NOT ALL, OF THE CWA AS WE END THE FORECAST PERIOD. RAIN
CHANCES WILL ALSO BE TOUGH TO COME BY DURING THIS TIME, WITH ONLY AN
ISOLATED SHOWER OR STORM POSSIBLE DURING THE HEAT OF THE DAY. /19/
