FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
515 AM CDT MON MAY 25 2026
DISCUSSION
OTHER THAN PERHAPS A FEW SPRINKLES ACROSS NORTHWEST ILLINOIS
AROUND MIDDAY, MOSTLY SUNNY SKIES AND DRY CONDITIONS ARE EXPECTED
TODAY. FORECAST HIGH TEMPERATURES ARE IN THE LOW TO MID 80S FOR
INLAND AREAS. AN EARLY AFTERNOON LAKE BREEZE WILL HOLD
TEMPERATURES IN THE 60S AND LOWER 70S NEAR THE LAKESHORE PAIRED
WITH HIGHER RELATIVE HUMIDITY VALUES.
MINIMUM RELATIVE HUMIDITY VALUES MAY DROP INTO THE 25 TO 35
PERCENT RANGE FOR INLAND AREAS THIS AFTERNOON, THOUGH CONFIDENCE
IS ON THE LOWER SIDE IN THE DRIER SOLUTIONS OWING TO THE
WIDESPREAD RAIN THAT FELL YESTERDAY MORNING POTENTIALLY LEADING TO
LOCALLY HIGHER HUMIDITY IN SOME AREAS.
TEMPERATURES ARE FORECAST TO REMAIN ABOVE NORMAL THROUGH MID TO
LATE WEEK FOR INLAND AREAS WITH ONSHORE WINDS KEEPING TEMPERATURES
COOLER NEAR LAKE MICHIGAN EACH DAY. THERE IS A LOW (20% CHANCE)
FOR ISOLATED SHOWERS AND STORMS ON WEDNESDAY FOR AREAS NEAR THE
WISCONSIN- ILLINOIS STATE LINE AS WELL AS AREAS NEAR AND SOUTH OF
US-24. OTHERWISE THERE ARE NO STRONG SIGNALS FOR RAIN THROUGH THE
END OF THE WEEK.
