DISCUSSION
ISSUED AT 132 AM CDT SUN SEP 14 2025
RIDGING OVERHEAD IS STILL CONTROLLING THE WEATHER PATTERN. HIGHS
WILL BE IN THE 90S FOR MOST OF THE NEXT WEEK, DROPPING TO ONLY THE
MID TO UPPER 60S OVERNIGHT. THE HOTTEST DAY IS TODAY, WITH HEAT
INDICES OF 95-100 DEGREES. WE MAY GET A BREAK IN THE SUMMERTIME
WARMTH BY THE END OF THE WEEK, AS UPPER TROUGHING BREAKS DOWN THE
RIDGING THAT HAS BEEN PREDOMINATELY IN PLACE. HIGHS START DROPPING
DOWN INTO THE UPPER 70S TO MID 80S BY LATE WEEK. HOWEVER, ABOVE
NORMAL WARMTH APPEARS TO CONTINUE, AS THE CPC KEEPS IT IN THE
OUTLOOKS THROUGH THE NEXT 3-4 WEEKS. NORMAL HIGHS FOR MID TO LATE
SEPTEMBER ARE AROUND THE MID 70S TO LOW 80S AND LOWS IN THE LOW TO
MID 50S.
THE FORECAST LOOKS TO BE PRIMARILY DRY, BUT THERE IS A 20% CHANCE OF
PRECIPITATION FOR WEST CENTRAL IL THIS AFTERNOON. RAINFALL AMOUNTS
IF SOMETHING WERE TO DEVELOP WOULD NOT BE IMPACTFUL. DROUGHT
CONDITIONS AND DRY AIRMASS WILL LIMIT THE CONVECTIVE DEVELOPMENT,
LIKE IT DID YESTERDAY. MORE RAIN CHANCES RETURN LATE IN THE WEEK.
THE NEXT BEST CHANCE FOR RAIN COMES THURSDAY INTO FRIDAY WITH A
40- 50% CHANCE. NONE OF THESE ROUNDS OF PRECIPITATION WILL BE
DROUGHT BUSTING, SINCE THERE IS ONLY A 15-20% CHANCE OF AN INCH OF
RAIN BY NEXT SUNDAY.
