SHORT TERM
(THROUGH LATE WEDNESDAY NIGHT)
ISSUED AT 254 PM CDT TUE JUN 6 2023
LOWS THIS EVENING WILL HANG AROUND THE MID-60S. WINDS WILL REMAIN
MAINLY LIGHT, BUT MAY BECOME STRONGER IF YOU ARE LUCKY ENOUGH TO
HAVE A THUNDERSTORM PASS THROUGH YOUR AREA. SKIES WILL REMAIN MOSTLY
CLOUDY INTO TOMORROW BUT WILL BEGIN TO DECREASE BY THE EVENING
HOURS.
THIS EVENING THERE IS A BACK-DOOR COLD FRONT PROGGED TO MOVE THROUGH
THE CENTRAL AND SOUTHEASTERN ILLINOIS REGION, BRINGING WITH IT A
CHANCE FOR SCATTERED SHOWERS AND THUNDERSTORMS. QPF FOR THIS SYSTEM
IS SHOWING ANYWHERE FROM A TRACE TO UP TO A TENTH OF AN INCH OF
PRECIPITATION. JUST ENOUGH TO LIGHTLY COAT THE GROUND AND VEHICLES.
HOWEVER, AMOUNTS COULD BE GREATER WITHIN ANY STRONGER SHOWERS OR
THUNDERSTORMS THAT MAY PASS THROUGH.
COOLER TEMPERATURES ARE EXPECTED TO FOLLOW CLOSELY BEHIND FOR
WEDNESDAY AND INTO THE WEEKEND. KEEPING HIGHS IN THE LOWER 80S FOR
WEDNESDAY.

LIGHT, VARIABLE WINDS. HIGHS FOR THESE DAYS LOOK TO BE IN THE UPPER

ASSOCIATED WITH THIS LOW PRESSURE SYSTEM THAT WILL CONTINUE FROM
SATURDAY THROUGH MONDAY MORNING, WITH THE GREATEST CHANCE FOR
SHOWERS AND THUNDERSTORMS ON SUNDAY. CURRENTLY, PRECIPITATION
AMOUNTS RANGE FROM 0.30 INCH NEAR GALESBURG TO 1.25 INCHES NEAR
LAWRENCEVILLE. THIS RAINFALL IS A VERY WELCOME CHANGE IN THE
PATTERN. SADLY, HOWEVER, IT WON'T PUT MUCH OF A DENT IN THE
CURRENT DROUGHT SITUATION.
TEMPERATURES WILL WARM BACK UP BY SATURDAY (HIGHS IN THE MID-TO-
UPPER 80S) BUT WILL COOL OFF AGAIN WITH THE NEXT COLD FRONT MOVING
THROUGH. SUNDAY AND MONDAY WILL BE IN THE MID 70S FOR THE HIGHS BUT
