441 AM CDT FRI JUL 17 2026
DISCUSSION
DENSE SMOKE FROM CANADIAN WILDFIRES AND ASSOCIATED HAZARDOUS AIR
QUALITY WILL REMAIN THROUGH MUCH OF THIS MORNING BEFORE
IMPROVEMENTS ARE EXPECTED DURING THE AFTERNOON AND EVENING. A FEW
ISOLATED SHOWERS MAY BRING LOCALIZED POCKETS OF HEAVY RAINFALL
THIS MORNING, WITH ADDITIONAL SCATTERED SHOWERS AND THUNDERSTORMS
ANTICIPATED DURING THE AFTERNOON AND EARLY EVENING. HIGHEST
COVERAGE OF RAIN TODAY IS EXPECTED NEAR AND EAST OF I-55.
MEANWHILE, TEMPERATURES WILL PEAK IN THE 80S AND LOWER 90S WITH
AFTERNOON HEAT INDICES AS HIGH AS 95 TO 100 DEGREES.
A COLD FRONT WILL PUSH ACROSS THE AREA FROM THE NORTH TOMORROW
PROVIDING ADDITIONAL CHANCES FOR THUNDERSTORMS, SOME OF WHICH
COULD BE STRONG TO SEVERE AND FEATURE DAMAGING WINDS AND
TORRENTIAL RAINFALL. THE BEST CHANCES FOR STORMS AROUND THE AREA
TOMORROW IS NEAR AND SOUTH OF I-80 THROUGH THE EARLY AND MID-
AFTERNOON, ALTHOUGH STORMS WILL BE POSSIBLE DURING THE MORNING
FARTHER NORTH AS WELL.
SMOKE CONCENTRATIONS MAY BE REINVIGORATED FOR LATE SATURDAY AND
SUNDAY BEHIND THAT COLD FRONT.
