DISCUSSION
ISSUED AT 247 AM CDT FRI MAY 8 2026
LINGERING SHOWERS HAVE BEEN PULSING ALONG AND NORTH OF I-74 THIS
MORNING. THESE WILL COME TO AN END IN THE NEXT FEW HOURS, WITH A
BRIEF BREAK BEFORE THE NEXT SHORTWAVE PRESSES INTO THE FORECAST AREA
LATE THIS MORNING. ADDITIONAL SHOWERS AND THUNDERSTORMS WILL DEVELOP
IN WESTERN IL AND WILL TRAVEL EAST THROUGH THE DAY, MAINLY ALONG AND
SOUTH OF THE I-72 CORRIDOR BY MID AFTERNOON INTO THE EVENING.
AMOUNTS WON'T BE OVERLY IMPRESSIVE WITH THE WAVE OF RAIN TODAY BUT
THE HIGHEST AMOUNT LOOKS TO BE SOUTH OF I-70. THE HREF IS SHOWING A
100% CHANCE OF TOTAL RAINFALL GREATER THAN 0.5 INCH AND 50% CHANCE
OF GREATER THAN AN INCH SOUTH OF I-70 FOR TODAY. IT LOOKS LIKE THE
WAVE OF RAIN TODAY MAY TRAIN OVER THE SAME AREAS THROUGHOUT THE DAY
SO SOME NUISANCE FIELD OR LOW LYING FLOODING MAY OCCUR WHERE
THE GROUND IS ALREADY SATURATED. THE CURRENT FORECAST DOES
APPEAR TO BE BELOW 6 HOUR FLASH FLOOD GUIDANCE, SO THAT IS
PROMISING.
THE FORECAST IS MOSTLY BENIGN OVER THE NEXT WEEK. A BRIEF WARM UP
SATURDAY INTO THE 80S, THEN COOLING BACK INTO THE 60S FOR THE NEW
WEEK. A GRADUAL WARM UP LOOKS TO BE ON DECK THROUGH THE NEXT WEEK.
SEVERAL PERIODS OF PRECIPITATION CHANCES ARE IN THE FORECAST AFTER
TODAY. THE BEST OF THOSE CHANCES LOOK LIKE TUESDAY WITH 20-50%
CHANCES AREAWIDE. THERE AREN'T ANY SEVERE CHANCES IN THE FORECAST AT
THIS TIME FOR THE NEXT 8 DAYS.
