FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
426 AM CDT SAT MAY 9 2026
DISCUSSION
SOUTHWEST WINDS GUSTING TO 25 MPH THIS MORNING WILL TURN NORTHWEST
AND SPORADICALLY GUST TO 35 MPH THIS AFTERNOON BEHIND A PASSING
COLD FRONT. WHILE SPRINKLES OR ISOLATED SHOWERS ARE POSSIBLE THIS
AFTERNOON, A VAST MAJORITY OF THE AREA WILL REMAIN RAIN-FREE.
DEEP MIXING WILL DEVELOP BEHIND THE FRONT, WITH MIXING HEIGHTS
QUICKLY GROWING TO 7KFT OR HIGHER. THE DEEP MIXING WILL ALSO
SUPPORT RH VALUES FALLING TO 30 PERCENT OR LOWER FOR SEVERAL HOURS
ACROSS MUCH OF NORTHERN ILLINOIS. BASED ON PRIOR DAY FUEL
MOISTURE VALUES OF UNDER 10 PERCENT AND SIMILAR OR LOWER VALUES
EXPECTED TODAY, ELEVATED FIRE WEATHER CONDITIONS ARE FORECAST.
COOLER AND LESS WINDY CONDITIONS ARE IN STORE SUNDAY AND MONDAY,
THOUGH AFTERNOON RH VALUES WILL STILL FALL INTO THE 30 TO 40
PERCENT RANGE. RAIN CHANCES WILL INCREASE ON TUESDAY, FOLLOWED BY
A GRADUAL WARMUP LATE WEEK INTO NEXT WEEKEND.
