DISCUSSION
ISSUED AT 200 PM CDT MON AUG 25 2025
THE FORECAST HASN'T REALLY CHANGED SINCE THE LAST FORECAST CYCLE
OVERNIGHT. TEMPERATURES WILL CONTINUE TO BE PLEASANT THROUGH THE
WEEK AND INTO THE WEEKEND. HIGHS IN THE MID 70S TO LOW 80S AND LOW
IN THE UPPER 40S TO UPPER 50S ARE EXPECTED. OVERNIGHT TONIGHT,
THERE IS A 30-50% CHANCE OF LOWS DIPPING BELOW 45 DEGREES IN SOME
LOCALIZED SPOTS ACROSS CENTRAL IL, BASED OFF THE HREF ENSEMBLE.
THE CPC INDICATES THAT BOTH THE 6-10 DAY AND 8-14 DAY OUTLOOKS WILL
HAVE BELOW NORMAL TEMPERATURES AND GENERALLY NEAR NORMAL
PRECIPITATION. THE NORMAL TEMPERATURES FOR THE LAST WEEK OF AUGUST
IS AROUND THE MID 80S FOR HIGHS AND LOW 60S FOR LOWS.
THERE IS A 15-25% CHANCE OF RAIN FOR AREAS NORTH OF I-74 ON THURSDAY
AS A SHORTWAVE PASSES OFF TO THE NORTH. THE SHOWERS SHOULD BE FAIRLY
LIGHT AND UNIMPACTFUL. WE ARE PRETTY CONFIDENT, HOWEVER, THAT MUCH
OF OUR FORECAST AREA WON'T SEE A DROP OF RAIN THROUGH THE END OF THE
FORECAST PERIOD.
