FIRE WEATHER PLANNING FORECAST FOR NORTHERN IL AND NORTHWEST IN
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
1045 AM CDT TUE APR 21 2026
DISCUSSION
GUSTY SOUTHWEST WINDS WILL PERSIST THROUGH THIS AFTERNOON, WITH
THE STRONGEST GUSTS (AROUND 35 MPH) ARE EXPECTED SOUTH OF I-80,
WHERE MINIMUM RELATIVE HUMIDITY VALUES ARE FORECAST TO FALL TO
AROUND 30 PERCENT. THIS AREA HAS RECEIVED NOTABLY LESS RAINFALL
COMPARED TO FARTHER NORTH, AND REPORTED FINE FUEL MOISTURE VALUES
WERE UNDER 8 PERCENT MONDAY AFTERNOON. AS A RESULT, THERE WILL BE
AN ELEVATED FIRE DANGER SOUTH OF I-80 (AND ESPECIALLY EAST OF
I-57) DURING THE AFTERNOON.
ISOLATED TO SCATTERED THUNDERSTORMS ARE FORECAST TO MOVE FROM
NORTHWEST TO SOUTHEAST ACROSS THE REGION THROUGH THE AFTERNOON,
SOME OF WHICH COULD PRODUCE STRONG WIND GUSTS.
A WEAK COLD FRONT WILL MOVE ACROSS THE AREA TONIGHT. THIS WILL
TURN WINDS ONSHORE NEAR THE LAKE, HOLDING TEMPERATURES AND MIXING
HEIGHTS MUCH LOWER LAKESIDE ON WEDNESDAY (TEMPERATURES IN THE 50S
RIGHT AT THE LAKEFRONT). INLAND, TEMPERATURES ARE EXPECTED TO WARM
INTO THE 70S. THERE IS A SLIGHT CHANCE FOR THUNDERSTORMS
WEDNESDAY AFTERNOON, BUT MAINLY WELL SOUTH OF I-80. WARM AND
BREEZY CONDITIONS WILL OCCUR ON THURSDAY, WITH ANY LAKE COOLING
LIMITED TO PARTS OF NE LAKE COUNTY (IL). PERIODS OF SHOWERS AND
THUNDERSTORMS WILL RETURN THURSDAY NIGHT INTO FRIDAY. DRY AND MORE
SEASONABLE CONDITIONS ARE EXPECTED OVER THE WEEKEND. ADDITIONAL
SHOWERS AND POSSIBLE THUNDERSTORMS MAY RETURN EARLY NEXT WEEK.
