AREA FORECAST DISCUSSION

..NEW AVIATION
KEY MESSAGES
- LIMITED LEVELS OF DANGEROUS HEAT STRESS CONTINUE ACROSS MUCH OF
THE AREA INTO THIS WEEKEND.
DISCUSSION
ISSUED AT 116 PM CDT WED SEP 9 2026
TONIGHT THROUGH NEXT TUESDAY...HIGH PRESSURE ALOFT AND AT THE
SURFACE WILL RELAX ITS GRIP ON THE REGION LATE THIS WEEK AND INTO
THE WEEKEND. THIS WILL ALLOW FOR BETTER CHANCES FOR SHOWERS AND
STORMS ACROSS THE AREA AS A WHOLE, AS WEAK TROUGHING ALOFT BUILDS
INTO THE REGION OVER THE WEEKEND. THE BETTER RAIN CHANCES WILL ALSO
RESULT IN A BIT OF RELIEF FROM THE ONGOING HEAT STRESS. HOWEVER,
HIGHS THROUGH SUNDAY INTO THE LOW AND MIDDLE 90S AND DEW POINTS
GENERALLY IN THE LOW AND MIDDLE 70S, WILL STILL YIELD AFTERNOON HEAT
INDEX VALUES NEAR 105F. THIS WILL CONTINUE TO RESULT IN A "LIMITED
THREAT" FOR DANGEROUS HEAT INTO THE WEEKEND.
AS THE NEW WORK WEEK ROLLS AROUND, THE AFOREMENTIONED WEAK TROUGH
WILL BE REPLACED BY STRENGTHENING HIGH PRESSURE ALOFT ACROSS THE
DEEP SOUTH. PERSISTENT SURFACE AND LOW LEVEL SOUTHERLY FLOW WILL
MAINTAIN PLENTY OF MOISTURE ACROSS THE FORECAST AREA MONDAY INTO
TUESDAY. ALTHOUGH OVERALL RAIN CHANCES WILL LESSEN DURING THIS
TIME, SOME ISOLATED TO SCATTERED CONVECTION WILL REMAIN POSSIBLE
DURING THE AFTERNOON HOURS AS HIGHS WARM INTO THE MID AND UPPER 90S.
ONCE AGAIN, SOME CONCERN FOR DANGEROUS HEAT STRESS MAY EXIST ACROSS
PORTIONS OF, IF NOT ALL OF, THE CWA. /19/
