DISCUSSION
ISSUED AT 218 AM CDT THU AUG 7 2025
THE UPPER LEVEL PATTERN THE NEXT COUPLE OF DAYS WILL FEATURE RIDGING
CENTERED ACROSS THE SOUTHWEST U.S. WITH WEAK TROUGHING ACROSS THE
SOUTHEAST U.S. MEANWHILE, THERE IS A WEAKNESS IN THE 500MB FLOW
NOTED OVER CENTRAL ILLINOIS EARLY THIS MORNING THAT IS EXPECTED TO
SINK SOUTH INTO OUR CWA TODAY. SEVERAL CAMS INDICATE SOME ISOLATED
CONVECTION MAY DEVELOP AS THIS WAVE PASSES THROUGH. WHILE THE BEST
CHANCE WOULD BE THIS AFTERNOON, CAN'T RULE OUT SOME ISOLATED SHOWERS
IN THE WABASH VALLEY/I-64 AREAS EARLY THIS MORNING. HAVE KEPT POPS
SILENT FOR NOW THOUGH, GIVEN THE LOW CONFIDENCE AND LIKELY LOW
SPATIAL COVERAGE OF ANYTHING THAT DOES DEVELOP.
AS THE TROUGH OVER THE SOUTHEAST U.S. WEAKENS, THE RIDGE TO OUR
SOUTHWEST WILL BUILD NORTHEAST INTO THE OHIO VALLEY AND EASTERN U.S
THIS WEEKEND. THE RIDGE THEN BECOMES CENTERED ACROSS THE SOUTHEAST
U.S. EARLY NEXT WEEK. WHILE THIS HAPPENS, SHORTWAVE ENERGY WILL MOVE
ACROSS THE NORTHERN PLAINS INTO THE UPPER MIDWEST. MODEL GUIDANCE
DOES NOT HAVE A GOOD HANDLE ON THIS SYSTEM, ESSENTIALLY BEING SPLIT
BETWEEN A POSSIBLE FRONTAL BOUNDARY SINKING SOUTH ACROSS THE MID-
MISSISSIPPI VALLEY TUES/WED OR THE POSSIBILITY IT REMAINS TO OUR
NORTH AND KEEPS US PRIMARILY DRY. FOR NOW, THE LOW CHANCE POPS THE
NBM HAS SEEMS REASONABLE.
TEMPERATURES WILL NOT VARY MUCH AT ALL THROUGH THE 7 DAY PERIOD,
WITH HIGHS PRIMARILY IN THE LOW 90S AND LOWS IN THE LOW 70S.
HUMIDITY LEVELS REMAIN SEASONABLE WITH DEW POINTS IN THE UPPER 60S
TO AROUND 70 THROUGH THE WEEKEND BEFORE A LITTLE UPTICK INTO THE LOW
TO POSSIBLY MID 70S OCCURS EARLY TO MID NEXT WEEK. PEAK HEAT INDEX
READINGS WILL PRIMARILY REMAIN IN THE MID TO UPPER 90S THROUGH THE
WEEKEND, AND THEN NUDGE MORE INTO THE UPPER 90S TO AROUND 100 NEXT
WEEK.
