FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
432 AM CDT WED SEP 23 2026
DISCUSSION
OTHER THAN A FEW LIGHT SPRINKLES EARLY THIS MORNING MAINLY NEAR
AND SOUTHEAST OF THE CHICAGO AREA, DRY WEATHER IS EXPECTED TODAY.
OTHERWISE, IT WILL BE MOSTLY CLOUDY AND BREEZY, WITH NORTHEAST
WINDS GUSTING TO AROUND 20 MPH AT TIMES, ESPECIALLY NEAR LAKE
MICHIGAN.
GRADUALLY DECREASING CLOUD COVER AND DIMINISHING WINDS ARE
EXPECTED THROUGH THE END OF THE WEEK, THOUGH TEMPERATURES WILL
REMAIN A BIT LOWER THAN AVERAGE FOR LATE SEPTEMBER. DAYTIME HIGHS
WILL GENERALLY BE IN THE 60S TO LOWER 70S, WITH NIGHTTIME LOWS IN
THE 40S AND 50S. THERE IS A SLIGHT CHANCE (20%) FOR A FEW SHOWERS
TO MOVE INTO WESTERN ILLINOIS LATE SATURDAY NIGHT INTO EARLY
SUNDAY MORNING, THOUGH THESE WILL LIKELY BE DISSIPATING AS THEY
ARRIVE AND MOST AREAS WILL BE DRY THROUGH THE WEEKEND AND INTO
EARLY NEXT WEEK.
