KEY MESSAGES
ISSUED AT 1220 AM CDT TUE SEP 8 2026

THE ACTIVITY WILL BE SOUTH OF THE AREA. BY THURSDAY, RISING

STORMS.
DISCUSSION
(TUESDAY THROUGH NEXT MONDAY)
ISSUED AT 1139 PM CDT MON SEP 7 2026
THERE ARE SOME LINGERING SHOWERS AND ISOLATED STORMS IN THE FAR
SOUTHWEST RIGHT NOW. THESE WILL DISSIPATE OR WORK INTO
MISSISSIPPI SHORTLY AFTER MIDNIGHT. THE STRONG GRADIENT FROM THE
EASTERLY WEDGE IS FORECAST TO KEEP THE BOUNDARY LAYER MIXED, WITH
SUSTAINED EASTERLY WINDS OF 5 TO 10 MPH. A FEW SPOTS IN THE
HIGHER ELEVATIONS ACROSS THE EASTERN AND NORTHEASTERN COUNTIES
MAY ACTUALLY OBSERVE SOME WIND GUSTS BETWEEN 15 AND 20 MPH
OVERNIGHT.
THE EASTERLY WEDGE WILL REMAIN IN PLACE THROUGH WEDNESDAY AS THE
500 MB RIDGE BUILDS ALOFT. RAIN CHANCES WILL REMAIN MINIMAL
THROUGH WEDNESDAY, GENERALLY LIMITED TO A 20-30% CHANCE OF
SHOWERS OR STORMS ALONG AND SOUTH OF I-85. WHILE TEMPERATURES
WILL REMAIN IN THE 90S, SLIGHTLY DRIER AIR ASSOCIATED WITH THE
EASTERLY WEDGE WILL KEEP CONDITIONS BELOW HEAT ADVISORY CRITERIA.
FORECAST CONFIDENCE IS INCREASING REGARDING THE PERSISTENCE OF
THE RIDGE THROUGH THURSDAY, WITH SOUTHERLY MOISTURE RETURNING TO
THE REGION ON FRIDAY. MEANWHILE, A COLD FRONT MOVING TOWARD THE
OHIO VALLEY IS EXPECTED TO LOSE UPPER SUPPORT AND STALL TO OUR
NORTHWEST BY FRIDAY AFTERNOON. THIS WILL LEAD TO INCREASED
DIURNALLY-DRIVEN RAIN CHANCES THROUGH THE WEEKEND, WITH HIGHS
CONTINUING IN THE LOW TO MID 90S.
